| 摘 要： | 选取资源型城市平顶山市为研究对象,以Landsat影像及统计资料为基础数据,对平顶山市2000~2011年各子区环境承载力与土地利用程度变化之间的关系进行研究,结果显示平顶山各辖区间土地利用变化与区域环境承载力呈正相关关系,且前者的变化幅度明显大于后者。在空间分布上,各评价单元的土地利用变化程度在不断提高,区域环境承载力除石龙区外均呈增加趋势;在时间分布上,评价单元内土地利用结构变化较大,大部分土地利用层级有所提升,区域环境承载力在主要子区上均有所增加。

| Abstract: | This article takes the resource - based city Pingdingshan as the research object, and researches the relationship between regional carrying capacity and land use changes in Pingdingshan. The result shows that land use changes＇ increase is as same as the regional carrying capacity generally and the former is more than the latter obviously. In the spatial distribution, the land use change of evaluation unit improves continuously, and the regional carrying capacity indicates growth trend except Shilong district. In the time distribution, the structure of land use changes enormously among evaluation unit, and most lands rise using hierarchy, and the regional carrying capacity indicates growth trend on most sub districts. |
