《全国主体功能区域》和"十二·五"规划确定"两屏三带"为主体的生态安全战略格局。本文以"两屏三带"中发挥华南和西南生态安全屏障的南方丘陵山地带为研究对象,以2000、2005和2010年三期土地覆被为主要数据源,采用转移矩阵和景观格局指数方法,对其土地覆被及景观格局变化特征进行了分析。结果表明:(1)十年来南方丘陵山地带的土地覆被景观类型以林地、耕地为主,分别占南方丘陵山地带总面积的75%和20%;(2)土地覆被变化主要是林地和耕地互相转换,人类在开采自然资源的同时实施了退耕还林、封山育林等生态工程;(3)自然景观斑块数量下降,形状更规则更简单,景观多样性指数上升,优势度稍稍下降,均匀度上...

The National Principal Function Regionalization and The 12th Five-Year Plan has set an strategic landscape of ecological security based on Two Barriers And Three Belts. Taking the land cover map data in 2000, 2005 and 2010 as main data source, this paper analyzes the characteristics of the changes of the land cover and landscape pattern in Southern Hillside during 2000-2010. The hillside secures the ecological environment in southern and southwest China. Transfer matrix and landscape pattern indexing are used for the analysis. The results shows...
