Abstract采用地理信息系统(GIS)技术,在ArcGIS 9.2和景观空间格局分析软件Fragstats 3.3的支持下,运用叠加分析(overlay)和景观的空间格局指数方法对淮河上游山丘区1990年、1995年和2000年3期的土地利用景观空间格局及其动态变化进行系统的分析研究,探讨其景观格局变化与相应生态过程之间的关系。结果表明:(1)1990—2000年的10a间,研究区景观结构总体未发生重大变化。(2)10a间,研究区内平原区水田景观类型向平原区旱地、林地和农村居民点用地景观类型转化的趋势显著。(3)10a间,研究区整体景观异质性上升,斑块趋向离散,连接性下降。(4)研究区后5a部分面积优势景观类型较前5a的破碎化程度均有减弱,斑块聚集度增加且连接性变强。(5)研究区生态系统结构和功能处于“局部改善、整体恶化”状态。
