基于耕地质量指数局部空间自相关的耕地保护分区研究——以敦化市为例
|
摘要
本文以敦化市为研究对象,以行政村耕地质量指数为空间变量,采用局部空间自相关分析方法,探究敦化市研究单元耕地自然等指数、利用等指数、经济等指数在空间分布上的集散程度及耕地质量空间差异性,并根据空间关联聚集图,进行耕地质量区域划分。研究结果表明,敦化市耕地质量在空间上呈现出空间正相关,具有较强的集聚性,HH型和LL型多以组团形式出现,HL型和LH型多以个体形式零散分布;从耕地质量差异化提升、精准化监测等方面提出保护举措,可为山地丘陵地区耕地质量保护和提升提供借鉴和参考。
Taking Dunhua city as the research object,local spatial autocorrelation analysis as the method and cultivated land quality index of administrative village as the spatial variable,this paper explores the spatial distribution degree of cultivated land natural index,utilization index and economic index in the research unit of Dunhua city and the spatial difference of cultivated land quality,and aggregates according to spatial correlation.The results show that the quality of cultivated land in Dunhua City is positively correlated in space and has strong agglomeration.HH and LL types mostly appear in the form of clusters,HL and LH types mostly scatter in the form of individuals;protection measures are put forward from the aspects of improving the quality of cultivated land differentiation and precise monitoring,which can be used for hilly and mountainous areas.The protection and promotion of cultivated land quality provide references and explorations.
