| 摘 要： | 借助黄河河口地区1996年5月和2004年9月两期的遥感影像,结合监督分类和非监督分类得到了该区两期土地利用数据。在ARINFO软件中计算得到土地利用转移矩阵,并分析两期土地流向及变化度。同时求得能表示景观离散程度、破碎状况、景观形状和多样性的景观结构指数。通过分析指出了整个研究区域总面积有所减少,盐碱地改良后用于了鱼虾养殖,但仍有部分未利用地和水域盐碱化,整个研究区域景观类型丰富且均匀,但居民地和工矿业的发展引起局部破碎度加剧。虽然黄河三角洲还有进一步发展的空间,但部分生态环境指标的恶化需引起重视和保护。

| Abstract: | Because of its fragile ecological environment and quick land use change, Yellow River Delta becomes a study focus for people to disclose human effects on ecological environment, tendency and reason of ecosystem changes. Two terms of satellite images are corrected and interpreted by using RS, and estuary is cut out as the study area. Using spatial analysis in ARC/INFO, land use map and landscape pattern indices are achieved. Subsequently, land flow direction, change ratio and landscape pattern indices differences are discussed. Results show that total decrease is 8201. 591 ha, while habitats and industry land increase 1. 387% per year. Salinized soil is improved for aquatic breeding, and also some unutilized soll and water region have been aggravated. For the whole study area, landscape category is plentiful and even, but at different parts fragmentation is intense. |
