基于改进信息熵的县域耕地整治潜力综合评价

Potential evaluation of county cultivated land remediation based on improved information entropy weight method

为提高耕地整治潜力测算的科学性,从数量、质量与生态3个方面构建了县域耕地整治潜力多因素评价体系,并采用改进信息熵确权方法与指数和法对盘山县耕地整治潜力进行定量化评价;在此基础上,采取Natural Break分级方法将盘山耕地整治区划分为5级潜力区;分析了不同潜力区耕地整治的可行性并提出了整治顺序,为盘山县开展耕地整治工作提供参考依据和技术支撑,也可为县级土地整治规划提供方法参考。

In order to improve the estimation accuracy of cultivated land remediation potential, we established a comprehensive evaluation index system of cultivated land remediation from aspects of quantity potential, quality potential and ecological factor. Furthermore, cultivated land remediation potential of Panshan County was evaluated by improved information entropy weight method and Synthetic evaluation method. Then, the study area was divided into five potential areas by using the Natural Break method. Finally, the feasibility of cultivated land remediation of different potential areas was analyzed and the order for remediation was proposed. The study can provide a scientific basis for land remediation work of Panshan county and a method reference for land remediation planning at the county level.
