摘要
城市发展水平不仅体现在社会效益与经济效益方面,在生态效益方面尤为重要,生态平衡控制是保障城市可持续化发展的重要途径。从提取层与分析层角度设计基于遥感图像的景观生态平衡控制系统。遥感图像边缘分割是系统提取层的核心,分割遥感图像边缘得到景观斑块分割结果。根据遥感图像景观斑块分割结果提取有效景观数据信息,计算分维数、多样性、均匀度等景观指数,分析景观生态平衡状况,据此制定合理的景观生态平衡控制方案,控制景观生态平衡。研究结果表明,该系统可精准分割遥感图像边缘,有效计算城市区域景观指数、分析生态平衡状况,合理控制区域景观生态平衡。
The urban development level is not only reflected in social and economic benefits,but also in ecological bene fits. Ecological balance control is an important way to ensure the sustainable development of cities. A landscape ecological balance control system based on remote sensing images is designed from the perspectives of extraction layer and analysis layer. The edge segmentation of remote sensing images is the core of the system extraction layer. The segmentation result of landscape patches is obtained by means of edge segmentation of remote sensing images. The effective landscape data information is extracted accord ing to the landscape patch segmentation result of remote sensing images. The fractal dimension,d iversity,evenness and other landscape indexes are calculated,and the ecological balance status of the landscape is analyzed,so as to make a reasonable landscape ecological balance control scheme for ecological balance control of the landscape. The research results show that the system can accurately segment the edges of remote sensing images,effectively calculate the landscape indexes of urban areas, analyze the ecological balance situation,and reasonably control the ecological balance of regional landscapes.
