摘 要:耕地是人类赖以生存的基本资源,耕地保护是事关国计民生的战略问题。为充分掌握耕地种植现状,及时为耕地保护提供数据参考,本文以寿光市为例,基于年度变更调查土地利用现状数据,采用核密度分析法、最近邻指数法、标准差椭圆法等方法对耕地进行统计分析,综合评估耕地及其种植属性空间分布特征,从而为后续耕地保护提供数据参考,进一步促进耕地资源可持续发展。Cultivated land is the basic resource for human survival,and cultivated land protection is a strategic issue related to the national economy and people’s livelihood.In order to fully grasp the current cultivation in cultivated land and provide data reference for cultivated land protection in time,this paper took Shouguang City as an example and used kernel density analysis method,nearest neighbor index method,standard deviation ellipse method,and other methods to analyze the cultivated land based on the data of current land use in annual change survey.The paper comprehensively evaluated the spatial distribution characteristics of cultivated land and its planting attributes,so as to provide data reference for the subsequent protection of cultivated land and further promote the sustainable development of cultivated land resources.
关 键 词:土地利用现状 耕地保护 空间分布 核密度 最邻近指数
