延边朝鲜族自治州耕地破碎度变化研究
Research on Change in Fragmentation Degree of Cultivated Land in Yanbian Korean Autonomous Prefecture
摘要
Abstract
In this paper,all cultivated lands in Yanbian Korean Autonomous Prefecture were taken as the research objects. By using the data of land use from 2010 to 2015,we evaluated and analyzed the fragmentation comprehensive index of cultivated land in all evaluation units in the researched area. The results showed that the degree of cultivated land fragmentation in all evalua-tion units became more and more serious. The fragmentation degree of all cultivated land in Yanbian Korean Autonomous Prefec-ture reached gradeⅡ or gradeⅢ at the end of 2015. In the researched area,the fragmentation degree of cultivated land in Dun-hua city was the most serious,and its growth rate was the fastest. Therefore,the cultivated land protection at present is necessary in Yanbian Korean Autonomous Prefecture.关键词
