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.
