Poor land use management and practice inhibit the growth and establishment of tree seedlings in dryland areas.We assessed arbuscular mycorrhizal fungi(AM)status of Faidherbia albida(Del.)A.Chev.trees grown on different land uses.We quantified the growth and nutrient uptake of F.albida seedlings inoculated with AM from different sources.These efforts were based on soil and fine root samples from the rhizosphere soils of F.albida trees.AM root colonization was determined using the gridline intersect method.Spores were extracted by the wet sieving and decanting method and identified to genus level.The seedling experiment had a completely randomized onefactorial design with four treatments and five replications.Faidherbida albida seedlings were grown in a greenhouse.All in situ F.albida trees were colonized by AM fungi.AM root colonization of F.albida trees was significantly higher(P<0.0086)in area exclosures than on lands used for grazing or cultivation.Spore abundance was significantly higher(P<0.0014)in area exclosures followed by cultivated land and grazing land.Glomus was the dominant genus in all land-uses.AM-inoculated F.albida seedlings grew better(P<0.05)than non-inoculated controls.Seedlings inoculated with AM from area exclosure had significantly(P<0.05)higher growth and nutrient uptake than those inoculated with AM from grazing and cultivated land.This emphasizes the importance of the native soil AM potential for better establishment of seedlings to achieve optimum plant growth improvement and assist in rehabilitation of degraded arid lands. 展开更多

Geomorphological regionalization(geomor-region)and geomorphological type(geomor-type)classification are two core components in the geomorphologic research.Although remarkable achievements have been made in the study of geomor-region,many deficiencies still exist,such as the inconsistency of landform indicators,the small quantity of division orders,disparities of geomorphological characteristics,differences of mapping results,and the small scale of zoning maps.Requirements for improved national geomor-regions are therefore needed for the purpose of an enhanced national geo-information system.Based on theories of geomor-region in China including plate tectonics,crustal features,endogenic and exogenic forced geomorphological features,and regional differentiations of geomor-type,a three-order(major-region,sub-region,and small-region)research program on China’s geomor-regions is proposed on the basis of previous 2013 geomor-region system.The major contents of the new geomor-region scheme are:(1)principles of the national multi-order geomor-regions;(2)hierarchical indicator systems of geomor-regions including characteristics of the terrain ladder under the control of tectonic setting,combinations of regional macro-form types,combinations of endogenic and exogenic forces and basic types of morphology,combinations of regional morphological types,and combinations of regional micro-morphological types;(3)naming rules and coding methods of geomor-regions;and(4)precise positioning techniques and methods of multi-order geomor-region divisions based on multi-source data.Using the new geomor-region theory and division methodology,the partition of national three-order geomor-regions of China was successfully constructed.The geomor-region system divided China into six first-order major-regions,36 second-order sub-regions,and 136 third-order small-regions.In addition,a database and management information system of the national geomor-regions were established.This research has an important guiding significance for promoting the d 展开更多

Soil productivity(SP) without external fertilization influence is an important indicator for the capacity of a soil to support crop yield.However,there have been difficulties in estimating values of SPs for soils after various long-term field treatments because the treatment without external fertilization is used but is depleted in soil nutrients,leading to erroneous estimation.The objectives of this study were to estimate the change of SP across different cropping seasons using pot experiments,and to evaluate the steady SP value(which is defined by the basal contribution of soil itself to crop yield) after various longterm fertilization treatments in soils at different geographical locations.The pot experiments were conducted in Jinxian of Jiangxi Province with paddy soil,Zhengzhou of Henan Province with fluvo-aquic soil,and Gongzhuling of Jilin Province with black soils,China.Soils were collected after long-term field fertilization treatments of no fertilizer(control;CK-F),chemical fertilizer(NPK-F),and combined chemical fertilizer with manure(NPKM-F).The soils received either no fertilizer(F0) or chemical fertilizer(F1) for 3-6 cropping seasons in pots,which include CK-P(control;no fertilizer from long-term field experiments for pot experiments),NPK-P(chemical fertilizer from long-term field experiments for pot experiments),and NPKM-P(combined chemical and organic fertilizers from long-term field experiments for pot experiments).The yield data were used to calculate SP values.The initial SP values were high,but decreased rapidly until a relatively steady SP was achieved at or after about three cropping seasons for paddy and fluvo-aquic soils.The steady SP values in the third cropping season from CK-P,NPK-P,and NPKM-P treatments were 37.7,44.1,and 50.0% in the paddy soil,34.2,38.1,and 50.0% in the fluvo-aquic soil,with the highest value observed in the NPKM-P treatment for all soils.However,further research is required in the black soils to incorporate more than three cropping seasons.The partial least squares 展开更多

Landslides in Tianshui Basin, Gansu Province, Northwest China, severely affect the local population and the economy;therefore,understanding their evolution and kinematics is of great interest for landslide risk assessment and prevention. However, there is no unified classification standard for the types of loess landslides in Tianshui.In this study, we explored the landslide distribution and failure characteristics by means of field investigation,remotesensinginterpretation,geological mapping, drilling exploration and shearwave velocity tests, and established a database of Tianshui landslides. Our analysis shows that shear zones in mudstone usually develop in weak intercalated layers. Landslides occur mainly along the West Qinling faults on slopes with gradients of 10° to 25° and on southeast-and southwest-facing slopes.These landslides were classified into five types: loess landslides, loess–mudstone interface landslides, loess flow-slides, loess–mudstone plane landslides and loess–mudstone cutting landslides. We discussed the evolution and failure process of each landslide type and analyzed the formation mechanism and motion characteristics of large-scale landslides. The analysis results show that the landslides in the study area are characterized by a gentle slope, long runout and high risk. The relationship between the runout L and the vertical drop H of the large-scale landslides in the study area is L > 4 H. There are good correlations between the equivalent friction coefficient of largescale landslides and their maximum height, runout,area and volume. The sliding zone of large-scale landslides often develops in the bedrock contact zone or in a weak interlayer within mudstone. From microstructure analysis, undisturbed mudstone consists mainly of small aggregates with dispersed inter-aggregate pores, whereas sheared clay has a more homogeneous structure. Linear striations are well developed on shear surfaces, and the clay pores in those surfaces have a more uniform distribution than those in undistur 展开更多

According to the geothermal geological conditions, the geothermal resources in Zibo can be divided into sedimentary basin type and tectonic basin type. The main thermal reservoirs of sedimentary basin type are the Neogene Guantao Formation and the Paleogene Dongying Formation.The thermal reservoirs of tectonic basin type are mainly the Ordovician Majiagou Group. The characteristics of reservoir, cap, pass and source of thermal resource types in different areas are elaborated. Based on the analysis of the wellforming conditions of the existing geothermal wells in the area, combined with the geothermal anomaly areas and hydrogeochemistry, it was discovered that the fault structures in the area, especially the deep faults such as Yuwangshan fault, Wangmushan fault, Zhangdian fault and Chaomizhuang graben, play an important role in controlling the occurrence and distribution of tectonic basin-type geothermal resources in Zibo City. 展开更多

Located in a monsoon domain,East Asia suffers devastating natural hazards induced by anomalous monsoon behaviors.East Asian monsoon(EAM)research has traditionally been a high priority for the Chinese climate community and is particularly challenging in a changing climate where the global mean temperature has been rising.Recent advances in studies of the variabilities and mechanisms of the EAM are reviewed in this paper,focusing on the interannual to interdecadal time scales.Some new results have been achieved in understanding the behaviors of the EAM,such as the evolution of the East Asian summer monsoon(EASM),including both its onset and withdrawal over the South China Sea,the changes in the northern boundary activity of the EASM,or the transitional climate zone in East Asia,and the cycle of the EASM and the East Asian winter monsoon and their linkages.In addition,understanding of the mechanism of the EAM variability has improved in several aspects,including the impacts of different types of ENSO on the EAM,the impacts from the Indian Ocean and Atlantic Ocean,and the roles of mid-to high-latitude processes.Finally,some scientific issues regarding our understanding of the EAM are proposed for future investigation. 展开更多

Assessment of the suitability of satellite soil moisture products at large scales is urgently needed for numerous climatic and hydrological researches, particularly in arid mountainous watersheds where soil moisture plays a key role in landatmosphere exchanges. This study presents evaluation of the SMOS(L2) and SMAP(L2_P_E and L2_P) products against ground-based observations from the Upstream of the Heihe River Watershed in situ Soil Moisture Network(UHRWSMN) and the Ecological and Hydrological Wireless Sensor Network(EHWSN) over arid high mountainous watersheds, Northwest China.Results show that all the three products are reliable in catching the temporal trend of the in situ observations at both point and watershed scales in the study area. Due to the uncertainty in brightness temperature and the underestimation of effective temperature, the SMOS L2 product and both the SMAP L2 products show "dry bias" in the high, cold mountainous area. Because of the more accurate brightness temperature observations viewing at a constant angle and more suitable estimations of single scattering albedo and optical depth, both the SMAP L2 products performed significantly better than the SMOS product.Moreover, comparing with station density of in situ network, station representation is much more important in the evaluation of the satellite soil moisture products. Based on our analysis, we propose the following suggestions for improvement of the SMOS and SMAP product suitability in the mountainous areas: further optimization of effective temperature;revision of the retrieval algorithm of the SMOS mission to reduce the topographic impacts;and, careful selection of in situ observation stations for better representation of in situ network in future evaluations. All these improvements would lead to better applicability of the SMOS and SMAP products for soil moisture estimation to the high elevation and topographically complex mountainous areas in arid regions. 展开更多

A recent study suggests that the deep dolomites in well Xike-1 located more than 1000 m deep have a very low porosity,and no permeability for most of the samples.Given that the largest oil and gas fields in the South China Sea are all composed of biohermal dolomites while the deep dolomites of Xike-1 serve as the caprock formations rather than the reservoirs,this represents the first discovery and is of great theoretical importance.In this paper,core photos of the tight dolomites are presented.Hand specimens description and systematic porosity-permeability reveal a very low porosity,and no permeability for most of the samples.PLM,SEM and XRPD analysis discovered that the dolostones in the deep tight dolomites are quite large in size and euhedral or subhedral in shape.Alizarin red-stained sections are mostly pink in color and have a full coverage,which are considered as evidence for multiple calcite intrusions after the formation of ankerite dolomites.Biological relict textures are developed.The order degree is medium to low.The dolomites could be the product of penecontemporaneous dolomitization. 展开更多
