【摘要】 基于GIS的空间分析平台,以景观生态学的方法建模,分析了北京市妫水河流域的景观格局特征,并与妫水河平原的景观格局特征进行了比较,发现在妫水河平原范围内,由于人为干扰程度的加剧,整体生态格局的异质性下降、碎裂化增加,景观生态格局的稳定性和安全性比之妫水河流域有所下降。分析了妫水河流域面临的问题及其原因,进而提出妫水河流域生态恢复的建议和措施。更多还原

【Abstract】 Using the ACRGIS Analysis platform, a landscape ecology model was developed to analyze the pattern characteristics of Gui Shui River watershed in Beijing. The modeling study produced important ecological indices for the 11 function-based landscape classes of the watershed and the overall watershed. A detailed discussion of the existing and potential problems facing the watershed is presented. Effective ecological rehabilitation measures are proposed to address the causes of these problems.更多还原
