In this paper, we obtained the spatial distribution of natural factors (eg, landform,precipitation,) and social-economical factors(as per capital revenue, land products, culture ratio ) used GIS. then analysis the relationship between farmer per capital revenue(FPCR) and other facts in order to investigated the influence factor to FPCR. The results demonstrated that the relationship have distinct time and spatal characteristic. The FPCR have obviously positive relationship with crop gross products, unit product, and irrigation rate, precipitation, it show that crop cultivation income always is the main source of FPCR in Zulihe River basin, the cropland products is the determinate factor. Noteworthiness,the noticeably negative relationship of FPCR with reclaim rate indicate that it is a myopia behavior to expand the area of cropland which not only can not enhance the income of farmer but also deteriorate agroecological environment,which will aggravate the so-called vicious circle of ecology-economy. Zulihe River located in the arid and semi-arid region of the Loess Plateau, the water resource is a key factor for elevating land products,so under the condition of limited water resource, and to elevate the utilization ratio of water resource to elevate the land productivity is the breakthrough point for improving the rural revenue.
