县级耕地质量等级更新研究——以江苏省睢宁县为例

Updating the County Cultivated Land Quality Grading——A Case Study of Suining County,Jiangsu Province

耕地作为土地最重要的组成部分,耕地质量等级更新研究对于科学利用耕地具有重要影响。该研究以睢宁县为研究区域,通过划分分等单元并建立参数体系,计算自然质量分值、利用系数及经济系数,得出自然等、利用等、经济等指数,划分出耕地质量等别,对县级耕地质量等级进行更新评价,用于对耕地数量、质量的一体化管理,为科学用地提供技术支持。

As the most important part of the land, the quality of cultivated land has important influence on the scientific use of arable land. Tak- ing Suining County as the study area, through the classification of grading units and establishment of parameter system, calculation of natural quality scores, using coefficient and economic coefficient, the nature, use and economic index were obtained, cultivated land quality was classi- fied. The quality level of county farmland is updated and evaluated, and the integrated management of quantity and quality of cultivated land is used to provide the technical basis for scientific land use.
