生态脆弱带水土流失对农业景观的影响——以云南省丽江地区永胜县为例

以云南省丽江地区永胜县为例，分析了生态脆弱带水土流失对农业景观的影响，认为生态脆弱区水土流失严重的主要原因在于自然环境的脆弱性及在其基础上过度的人类活动，从农业景观要素和景观格局两方面讨论了水土流失对生态脆弱区农业景观的影响机制和结果，最后指出发展生态农业和区域的水土流失整治共同进行，才是生态脆弱区可持续发展的道路。

Effects on Agriculture Landscape by Water and Soil Loss in Ecotone

The authors analyse the effects on agriculture landscape in the ecotone by water and soil loss in a case study carried out in Yongsheng, Lijiang, Yunnan Province. The most important reasons of the effects are the special environment and human activities in ecotone. Research of factors and patterns of agriculture landscape can be used to study the mechanisms and results of the effects on agriculture landscape by water and soil loss. Eco-agriculture and controls to water and soil loss should be the best way to have sustainable development in ecotone.
