Preliminary Theory of Adaptation Mechanisms of Soil Erosion in Agr icultur al Landscape
农业景观对土壤侵蚀的适应机制研究初探

The consensus of atmospheric scientists is that climate change is occurring and affecting agricultural system increasingly. To maintain food security at a regional scale, we should recognize the key adjustable factors in agriculture management and design an optimized plan for agricultural landscape under climate change. This paper aimed at future soil erosion changes and tried to construct a research scheme for adaptation in agricultural landscape by combing related environmental factors. Firstly, to provide a scientific basis for prediction of soil erosion trends at various spatio-temporal scales, we summarized related studies about the influences of climate and land use change on soil erosion. Secondly, from the point of strengthening the adaptation ability to soil erosion, the relationships between landscape characteristics (landscape types, spatial patterns and crop management conditions) and soil erosion were fully discussed to improve the adaptation of optimized configuration in agricultural landscape. Finally, for evaluating the adaptation degree of agricultural landscape, soil loss and runoff were then predicted with an agent-based erosion model under future climate scenarios, which can help management of valuable cropland and suggest the need for continually changing soil conservation strategies.
