泉州市土地利用结构的量化分析与评价

Quantitative Analysis and Evaluation of Land Use Structure in Quanzhou City

根据2009年第二次全国土地利用现状调查数据,运用数学方法并结合GIS技术,从县级尺度对泉州市的土地利用结构及其区域差异与成因进行定量分析,提出土地利用和城乡建设的差别化政策建议。研究结果表明:定量分析方法能很好揭示区域土地利用结构的地域分异,全市比较明显地存在4种不同的土地利用结构模式;影响研究区土地利用结构县域差异的主要因素与土地利用结构指数之间存在明显关系。

Using data from the second national land use survey of 2009,and a variety of mathematical models and GIS technology,this article quantitatively analyzes land use structure and its regional differences at the county scale,as well as the causes of these differences,in Quanzhou city.This article also suggests new policy ideas for land use and urban-rural construction.The results show that quantitative analysis clearly reveals the regional differences in land use structure,and four regions of differing land use structure were identified in Quanzhou city.In addition,a significant linear relationship,or non-linear correlation,exists between the main factors that affect the structure of countywide differences,and the land use structure index.
