| 摘 要： | 在GIS支持下,以1993、2000和2007年TM影像为数据源,利用景观/斑块类型面积、斑块个数、拼块所占景观面积的比例、分维数、破碎度指数、多样性指数、均匀度指数、蔓延度指数等景观特征指标,从类型和景观水平对采煤沉陷区景观特征及其动态变化进行了研究.研究结果表明大南湖沉陷区在最近15年景观格局发生了很大的变化,以建设用地、耕地为主导的区域景观被打破,形成了以建设用地、水域、林地为主导的区域景观格局;开采活动和人为土地复垦是造成采煤沉陷区景观变化的主要因素.

| Abstract: | On the basis of GIS technology, such indexes as umber of patches, patch area, PLAND, fractal dimension index, fractal index, diversity index, evenness index and TM images in 1993,2000and 2004 were used to study the regional landscape characteristics and its dynamic changes of mining subsidence area. The result shows that landscape in study area changes greatly in recently 15years. The regional landscape leading by construction land and plantation was replaced by construction land, water and woodland, and th... |
