耕地管理条件空间分布特征及分区——以湘乡市为例

Spatial Distribution Characteristics and Zoning of Cultivated Land Management:A Case Study of Xiangxiang City

以湘乡市2022年耕地利用现状调查数据为基础,运用AHP层次分析法构建耕地管理条件评价指标体系,系统评价了湘乡市村域的耕地管理条件,并运用GIS技术和空间自相关分析方法对其进行空间特征分析与分区。结果表明:湘乡市耕地管理条件整体处于中上水平,并且在空间上呈现出明显的集聚分布特征,耕地管理条件较好的村庄主要分布在市域中北部和中南部地区,耕地管理条件较差的村庄主要分布在市域西北部和西南部地区。结合局部空间自相关分析结果,将湘乡市村域耕地分为稳定管理区、综合管理区和重点管理区三类,在实际的管理过程中,要结合村域耕地特点和实际基础设施情况进行因地制宜的保护管理。

The survey data of cultivated land use in Xiangxiang City,2022 and the analytical hierarchy process(AHP)were employed to establish an evaluation index system of cultivated land management,which was used to systematically evaluate the cultivated land management on a village scale in this city.Furthermore,the geographic information system(GIS)and spatial autocorrelation analysis were employed to characterize the spatial pattern and determine the management zones.The results showed that the cultivated land management in Xiangxiang City was generally at the middle and upper levels,with obvious spatial agglomeration distribution.Specifically,the villages with mature cultivated land management were mainly concentrated in the north-central and south-central areas,and those with poor management were mainly concentrated in the northwestern and southwestern areas of the city.According to the results of local spatial autocorrelation analysis,the cultivated land management in this city was zoned into three categories of stable management,comprehensive management,and prioritized management.Measures should be taken according to the local characteristics and infrastructures of the villages.
