Abstract:

In order to improve the utilization efficiency of agricultural land in Zhuji City, this study analyzed and evaluated the suitability of agricultural land in Zhuji City. Five indicators including elevation, slope, soil texture, organic matter content and water resources availability were selected to represent the suitability of agricultural land in Zhuji City, and corresponding evaluation models were established afterwards. In the single factor evaluation, the highly suitable areas for elevation, slope and water resource availability accounted for more than 30% of the total area, while the highly suitable areas for soil texture and organic matter content only accounted for less than 10%. While in the comprehensive evaluation of agricultural land, the proportion of highly suitable areas for cultivated land, garden land and forest land was about 40, and they were mainly distributed in the central area of Zhuji City, and the suitability of areas in the west, East and South Zhuji was lower. The above results can provide reference for the agricultural land planning of Zhuji City.

Key words: Zhuji, agricultural land, land suitability analysis, geographic information system
