平塘县土地利用变化与社会经济发展的相关性分析
|
摘要
以平塘县为研究对象,基于"3S"技术手段,分析其土地利用动态变化特征,构建土地利用结构与社会经济结构相关性评价指标体系,采用二元相关分析法定量分析平塘县土地利用结构与社会经济结构变化的相关性。结果表明:1)2000-2013年,平塘县耕地持续减少,其中水田减少最多,林地增长速度较快,建设用地持续增加;2)平塘县人口密度与土地利用程度指数呈显著正相关,经济密度与耕地比重、未利用地比重呈显著负相关,与建设用地比重呈显著正相关,第一产业占总GDP比重与耕地比重呈显著正相关,第二、三产业占总GDP比重与建设用地比重呈显著正相关。
Taking Pingtang County as the research object,based on 3S technology,we analyzed its land use dynamic change characteristics,constructed the relativity evaluation index system of land use structure and social economic structure,quantitatively analyzed the relativity between land use structure and social economic structure by using binary relativity analysis method. The results showed that:( 1) the cultivated land in Pingtang County continued to decrease from 2000 to 2013,and the paddy field showed the most reduction; but the construction land continued to increase,and the forest land increased fastest.( 2) In Pingtang County,population density and land use degree index had significant positive correlation; economic density and the proportion of cultivated land / unutilized land had significant negative correlation,but economic density and the proportion of construction land had significant positive correlation. The proportion of primary industry in the total GDP and the proportion of cultivated land had significant positive correlation,and the proportions of secondary industry and tertiary industry,and the proportion of construction land had significant positive correlation.
