快速经济发展下县级土地利用/覆被空间变化分析

土地利用/覆被变化(LUCC)是人类活动对自然环境施加影响的显著表现形式。本文以案例的形式,运用LUCC度量模型和LUCC转移矩阵分析研究区清新县2001-2007年的LUCC空间格局变化,并对全县土地利用/覆被进行了分区。研究结果表明,清新县2001-2007年面积增加最多的为林地,而减小最多的为耕地,期间全县综合土地利用/覆被动态度为2.77%、土地利用/覆被强度从2.163增至2.172;同时,清新县土地利用/覆被存在着较为明显的空间差异,全县土地利用/覆被区划可分为南部综合服务中心区、中部产业转移区和北部生态脆弱区三个功能区。

Study on land use/cover spatial change on county scale in the rapid economic development region

Land use / cover change （LUCC） is the obvious represent that human behave effect on the environment. In this paper, we illustrated how to apply land use change model and LUCC transfer matrix to evaluate land use / cover special pattern change and direct the functional zoning by the case of Qingxin County from 2001 to 2007. The result showed that the largest increase was woodland area in the whole coun- ty during the period; however the largest decrease was arable land area. The comprehensive land-use dynamic degree was 2.77%, and the land use intensity increased from 2.163 to 2.172.According to the obvious spatial differences of the land use, the county could be divided into three different functional zones that were the southern comprehensive serving central zone, middle industry transfer zone and northern ecologically fragile zone respectively.
