Abstract: Based on the data of land quality survey in Honghu city, an evaluation system composed of soil nutrient index and environmental index are established. According to The land quality geochemical assessment specification (DZ/T 0295-2016), the land quality geochemical assessment and spatial distribution of the land are studied. The soil in Fengkou town, Wanquan town of Honghu city is divided into five gradesHigh quality, good, medium, poor, inferior. The results show that the overall land quality status of the evaluation area is in good condition, with land of high quality and above accounting for 80.91% of the evaluation area, among which land of high quality accounted for 54.01%.
