Spatial Distribution Characteristics of Arable Land Grade in Chenggu

Abstract:

The purpose of this paper is to grasp the distribution characteristics of arable land quality. Methods employed are system analysis method and spatial analysis function of ArcGIS. The results show that the arable land quality is relatively higher compared to the national level. Differences of arable land grade were significant among different agricultural grading zones. The arable land grade of Han River plain area is the highest. The grades of irrigable land and paddy field are higher than dry land, and the irrigable land is the highest. Topography, soil, irrigation conditions, population density, economic development level are the main factors causing the difference of arable land grade spatial distribution. The research can provide a scientific basis for policies and measures making about arable land quality protection and grade improvement.
