-
Acurately elavuating the utilization situation of the usually coupled agricultural water and land resources is very helpful for improving the productivity of agricultural water and land resources in related areas. We provide a geogrid-based framework of agricultural zoning in 109 counties of Shaanxi Province throught using principal component analysis and cluster analysis. The results show that the geogrid-based zoning method has a good applicability in agricultural zoning, through which the agricultural zones in Shaanxi Province can be divided into five regions and 17 subregions based on data of 36 903 geogrids. The five regions show distinct differences. Region Ⅰ possesses sufficient hydrothermal resources, where the water resource utilization is the best and the land resource utilization is moderate. Region Ⅱ possesses good hydrothermal resources, and the land resource utilization is also good. Region Ⅲ possesses general hydrothermal resources, where the water resource utilization is good and the land resource utilization is moderate. Region Ⅳ possesses a moist climate, where the water resource utilization is good and the land resource utilization is relatively poor. Region Ⅴ possesses a arid climate with relatively low temperature, where the water and land resources are insufficient and the land resource utilization is the poorest. The polygons of subregions generally distribute in the middle area of Shaanxi Province. The results of zoning reflect the current development and utilization of agricultural water and land resources in related regions of Shaanxi Province, and clarify the degree of match between agricultural water and land resources and their utilization potential in agriculture, which lay the foundation of effective utilization of water and land resources in agricultural areas in this province.
