摘  要:
[目的]以新疆鄯善县耕地质量为研究对象,构建耕地质量预警指标体系,[方法]运用熵权法和相关性分析筛选出对耕地土壤属性、自然环境条件以及农田基本建设影响比较大的指标作为耕地质量预警的警情指标;阐述了2007-2018年耕地质量存在的警情,在此基础上引入线性回归预测模型对鄯善县2020-2030年耕地质量的警情进行了预测,并进行综合警度的划分。[结果]结果表明:鄯善县耕地质量综合警情朝着恶化的趋向进行。[结论]鄯善县耕地质量恶化。

摘  要:
Taking the quality of cultivated land in Shanshan County of Xinjiang as the research object,an early warning index system of cultivated land quality was constructed,and entropy weight method and linear regression method were used to select the index that had a relatively large impact on the soil properties,natural environment conditions,and farmland infrastructure construction as the warning index of cultivated land quality. This paper expounds the warning situation of cultivated land quality from 2007 to 2018. Based on this,the relevant forecasting model is introduced to predict the warning situation of cultivated land quality in Shanshan County from 2019 to 2028,and the comprehensive warning level is divided.The results show that the comprehensive alarm situation of cultivated land quality in Shanshan County tends to deteriorate.
