摘要:
应用1991年的TM图像和2006年的ETM图像，将研究区湿地类型分为自然湿地（包括河流湿地、湖泊湿地、灌丛湿地）和人工湿地（包括水塘、输水渠、水产池塘），提取研究区两个时期的湿地景观，并应用斑块数量、斑块面积、斑块密度、多样性指数、优势度指数、均匀度指数和分维数指数分析了研究区的湿地景观变化情况。结果表明：1991-2006年银川市湿地斑块数量和面积减小幅度很大，但水产池塘的斑块数量与面积呈增加趋势。1991年研究区自然湿地比例远大于人工湿地，但到2006年两种湿地类型比例相当。从景观水平来看，研究区湿地的Shannon多样性指数与均匀度指数减小，优势度指数增加。
Abstract:
Based on the TM images of 1991 and ETM images of 2006, the wetlands types were classified as nature wetland and artificial wetland, and the wetland landscape of two periods was picked. The landscape pattern was analyzed based on the index of the plot area and number, fragmentation, diversity, dominance, eveness and fractal dimension. The result indicated that the plot area and number of the wetland decreased severly from 1991 to 2006, but the aquatic ponds increased. The proportion of nature wetland was greater than artifical wetland in 1991, but it was almost equal until 2006.On the landscape pattern, the diversity and eveness decreased, and the dominance increased.
