耕地"非农化"与"非粮化"空间格局特征及对策研究
Research on the spatial pattern characteristics and countermeasures of"non-agricultural"and"non-grain"cultivated land
摘要
Abstract
Based on GIS technology,this paper studied the land use data of central Yunnan urban agglomeration in 2000,2010 and 2020,and introduced the"non-agricultural"and"non-grain"cultivated land speed model,standard deviation elliptical model,cen-ter of gravity model and spatial self-correlation model to quantitatively reveal the spatial distribution and agglomeration characteristics of"non-agricultural"and"non-grain"cultivated land in the central Yunnan urban agglomeration in the past 20 years,and proposed corresponding countermeasures to prevent"non-agricultural"and"non-grain"cultivated land.The results showed that:①There were significant spatial differences in the rate of"non-agricultural"cultivated land in various counties and cities in central Yunnan re-gion.The rate of change was the largest in the central region,and the northwest and northern regions were slower.②The spatial differ-ence in the rate of"non-grain"cultivated land from 2000 to 2010 was that the further away from Kunming City,the greater the rate of"non-grain"cultivated land.From 2010 to 2020,the rate of"non-grain"cultivated land in various counties and cities was mainly at level 2 and level 3,with a relatively balanced distribution.③During the research period,the center of gravity and spatial distribution of"non-agricultural"and"non-grain"cultivated land shifted towards the northeast direction.④There was a strong spatial agglomera-tion between the"non-agricultural"and"non-grain"cultivated land,and this agglomeration trend was increasing.关键词
