摘  要:
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.
