摘要
在RS和GIS技术的支持下,以2003年的IKONOS和2006年QUICKBIRD高分辨率遥感影像为主要数据源,利用面向对象分类方法获取西溪湿地景观数据,研究和分析了西溪国家湿地公园实施综合保护工程前后的景观格局变化。结果显示,各类湿地面积均有不同程度的变化,景观多样性指数和均匀度指数上升,连通性有所增强;优势度指数和聚集度指数降低,景观破碎化程度有所增加。西溪湿地景观格局的变化,反映了人类有目的、有选择的进行改造和优化的结果。
Under the support of RS and GIS technology, landscape data of Xixi National Wetland was obtained by object-oriented image classification method based on high-resolution remote sensing image of IKONOS in 2003 and QUICKBIRD in 2006. Analysis on landscape pattern changes before and after protecting project in the wetland showed that different types of wetland area changed, diversity and evenness index increased, connectedness enhanced, dominance index and contagion index reduced, but fragmentation increased. The changes of landscape pattern in the wetland reflected the result of human activities.
