【摘要】 城市公园湿地景观的空间格局分析是城市湿地生态系统研究的重要内容。本研究尝试应用1m分辨率的IKONOS遥感图像,利用RS、GIS等先进技术,获取城市公园湿地景观数据。运用景观生态学的原理,采用多样性指数、优势度指数、破碎化指数和斑块的分数维等空间结构指标,对北京市城市公园湿地的景观格局进行了研究和分析。更多还原

【Abstract】 The IKONOS image provides the 1m high spatial pan and the 4m multi-spectral data, which can be merged to improve the classification accuracy of visual or computational interpretation. Based on these images, the classification and distribution of wetlands in Beijing urban parks were examined. In this paper the authors studied the landscape patterns with the help of remote sensing and GIS. The result shows that the urban parks are composed of large patches. The shapes of patches are regular in the area, and the difference in patches of the same type is very indistinct. With the increasing disturbance, the landscape diversity decreases and the dominance increases.更多还原
