Mountainous eco environment is an important basis of generating natural agro resource,some environmental factors such as soil,vegetation,hydrology and climate are the composing part of agricultural resources.Their match and constitution can reflect the different patterns and spatial heterogeneity of eco environment. In this paper taking Qin Ba mountain of Shanxi Province as an example,the authors point out that has reliability to reveal the environmental structure,function and distribution laws of agricultural resources by using RS and GIS to evaluate qualitatively land ecotype and divide different ecotype zone. The agricultural resources involve agricultural environmental resources,economical product and social labor resources.The environmental resources ,which can be regarded as basis of generating the economical resources,are related compactly with regional eco environment and abided by the zonal principle of mountain land.The economical resources,which are the physical form of the environmental resources,are related directly with appointed agricultural action and abided by eco economy theory .The social labor resources,whose effect shows dualism,are regarded as the main body and ligament that integrate above two kinds of resources. The essence of agro resources sustainable use is to combine the sustainability of environmental resources system with sustainable increase of agro products to meet the demand of getting rid of poverty and realizing sustainable development of society and economy by giving play to the positive actions of labors in mountainous area.
