The impacts of vegetation restoration on the soil erosion have been widely elucidated in the semi-arid ***,the magnitude of soil erosion on abandoned sloping farmland still remained unclear and their responses to vegetation succession were rarely *** main objective of this study is to determine the magnitude of soil erosion along vegetation succession and explore the impact of vegetation succession on soil erosion from abandoned sloping *** observations were employed to monitor the rainfall,runoff,and soil erosion of seven sloping farmland plots with different abandoned ages and bare land from 2015 to *** results indicated that the annual runoff depth and soil erosion modulus of vegetation types were in the range of 0.46 to 5.49 mm·a^(-1)and 1.3 to 24.5 t·km^(-2)·a^(-1),*** vegetation effectively reduced the annual surface runoff and soil erosion with reduction of 73.8% to 97.8%and 98.0% to 99.9% as opposed to bare ***,there were no significant differences in runoff and soil erosion for different vegetation types along *** largest event of vegetation types contributed to 38.7%-44.1% of the annual runoff and 42.5%-66.3% of the annual soil erosion,*** restoration considerably alleviated the contribution of largest erosive event to annual soil *** relationships between soil erosion,runoff and rainfall factors could be fitted well by linear functions,and the performances of regression models in predicting runoff were more satisfactory compared to predicting soil *** Artemisia gmelinii(Agm)+Stipa bungeana(Sb)optimized the trade-off between sediment reduction and runoff maintenance,which should be selected as the suitable vegetation types to achieve the sustainability of socio-ecological systems.

Severe soil and water loss have led to widespread land degradation on the Loess Plateau in *** the relationship between land use and sediment connectivity can be beneficial to control soil *** this study,three catchments in the Yanhe River Basin on the Loess Plateau were selected to analyse the relationship between land use and sediment connectivity using grey correlation *** of connectivity(IC)was employed to quantify sediment connectivity,including two flow direction algorithms(D8 and D-infinity)and two final targets of sediment transport(outlet and main channel of catchment).Then,11 landscape metrics were used to evaluate the land use spatial patterns of *** comparing the IC value ranges,histograms and classes,and their relationship with remote sensing images of the two flow direction algorithms,we find that the D8 algorithm is more suitable for this study *** results showed that the three catchments are characterized by high sediment connectivity in the grassland and forest close to the *** addition,the roads and bare land close to the channel also have high or medium sediment *** correlation analysis showed that landscape division index(DIVISION),fractal dimension index(FRACMN),aggregation index(AI),total class area,patch cohesion index(COHESION),and largest patch index(LPI)indices were the main factors that affect sediment connectivity at the class *** the landscape scale,the landscape shape index(LSI),Shannon’s diversity index(SHDI),and gully density have an essential effect on sediment *** condition provides a way to control the sediment connectivity in the watershed by transforming land use type or changing its spatial pattern,but specific adjustment measures have to be further explored.

为探讨自然降雨条件下不同施肥模式和耕作方式对坡耕地紫色土肥力质量的影响,通过采集监测时长为9年的径流小区径流和土样,测定了径流量、有机质、全氮、全磷、全钾、速效磷、硝态氮和铵态氮等指标,运用灰色关联法建立了土壤肥力质量评价指标体系,分析了土壤肥力水平与施肥模式、耕作方式之间的关系。结果表明:5种不同试验处理下,各土壤肥力因子均有不同程度下降,其中土壤硝态氮和铵态氮含量减少最为显著;评价土壤肥力的关联度逐年减小,横坡耕作单施化肥处理的多年平均关联度表现最大,对应的多年平均径流量最小;顺坡耕作方式下,农家肥和化肥配施处理的多年平均关联度最大,对应的多年平均径流量最小,对照处理则相反;多年平均径流量与多年平均关联度之间满足线性函数模型y=-0.000 2x+0.762 8(R^2=0.748 4),随着径流量的增大,土壤肥力质量显著下降,二者呈负相关关系。横坡耕作下农家肥和化肥配施处理对于维持土壤肥力水平以及减少地表径流量效果最优。

土壤侵蚀是全球性的环境问题,河流输沙量常被用于评估流域的土壤侵蚀程度,而流域出口监测的输沙量是把整个流域内部当作"黑箱"处理,这可能会忽视流域内的侵蚀热点区或由于泥沙淤积而造成的潜在风险区。泥沙连通性这一概念可用于理解土壤侵蚀与泥沙输移过程及其时空分布。针对国内泥沙连通性研究刚刚起步的现状,梳理了泥沙连通性的研究方法,分别为实地观测法、示踪法、模型法、指标法和图论法五类。通过分析不同方法应用的优缺点,认识到今后的研究应在精确评估结构连通性的基础上,结合影响泥沙输移的外力因子及其对应的过程,探求量化流域内部泥沙输移动态的方法,以此为更精细的流域管理和泥沙连通性研究提供技术支持。

Based on the Melnikov method,we investigate chaotic behaviors in the extended thermodynamic phase space for a slowly rotating Kerr-AdS black hole under temporal and spatial *** results show that the temporal perturbation coming from a thermal quench of the spinodal region in the phase diagram may cause temporal chaos only when the perturbation amplitude is above a critical value,which involves the angular momentum *** the spatial perturbation,however,it is found that spatial chaos always occurs,independent of the perturbation amplitude.
