Abstract:Farming system is an important way to affect the ecological environment in the ecotone between agriculture and animal husbandry of north China,and the irrational farming system has made the local environment deteriorated.Characteristics of soil physical properties change,including wind speed,soil tightness,soil organic matter,soil moisture,soil roughness,the ratio of vegetation coverage,and so on,were studied under different farming systems,including abandoning cropping system,fallow cropping system,rotational cropping system,and conservation cropping system with Wuchan county as case study.The result showed that different farming system had obvious influence on wind speed,soil tightness,soil organic matter,soil moisture,soil roughness,the ratio of vegetation coverage and the mass of wind erosion,and the conservation cropping system could decrease soil erosion obviously and prevent land desertification effectively.The conservation cropping system should be extended in order to promote the sustainable development of agricultural production in the ecotone between agriculture and animal husbandry.
