Spatial distribution characteristics of cultivated land planting attributes based on current land use
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.
