摘要:
掌握耕地质量指数的空间集聚性和异质性特征，对耕地质量利用分区管理与制定差异化保护政策提供科学依据。运用江苏省2016年度耕地质量等别更新数据库，以耕地质量指数为空间变量，采用面积加权平均法和空间自相关的分析方法，计算县区的耕地质量等别指数，探究耕地质量等别指数的集聚性规律和异质性特征。结果表明：（1）苏南地区耕地质量等别在空间分布上呈现较强的集聚性规律，呈现由东南向西北逐级递减的趋势；（2）苏南地区耕地质量整体上呈现显著的空间正相关特征，从全局Moran’s I值分析，表现为国家利用等指数>自然等指数>经济等指数；（3）从县级耕地质量局部空间自相关分析得出耕地质量HH型呈现组团集中分布特征，LH型和HL型则零星分散在个别县区，LL型按条带状集中分布。研究基于县区耕地利用特点与局部空间自相关分析类型，将苏南地区划分为重点保护区、质量提升区、结构调整区和优先建设区4个耕地保护分区。
Abstract:
We explored the spatial structural characteristics and agglomerate regulation of cultivated land quality by taking the cultivated land quality index of 2016 in Jiangsu Province as the spatial vaiable. In addition, we analyzed the reasons for the differences in the studied area by using the cultivated land quality index. The results indicated that the cultivated land quality exhibited the strong agglomeration pattern in spatial distribution in the south of Jiangsu Province besides that the local distribution of cultivated land quality showed that the level of northwest area was less than southeast. The quality of cultivated land had a significant spatial positive correlation in the south of Jiangsu Province. From the overall Moran’s I value analysis, the performance index decreased in the order:utilizing the index > nature index > economic index; according to the analysis of local spatial autocorrelation of cultivated land quality at county level, the HH type of cultivated land quality showed cluster concentration distribution characteristics, LH type and HL type scattered in individual counties, but the LL type of cultivated land mostly distributed in strips. Based on the characteristics of cultivated land use and local spatial autocorrelation analysis in the counties, the southern part of Jiangsu Province is divided into four arable land protection areas such as key protected areas, quality improvement areas, structural adjustment areas, and priority building areas. The measures were also put forward for differential farmland protections.
