基于分形理论的湖州市城市生态系统健康评价
Urban ecosystem health assessment of Huzhou, Zhejiang Province of East China based on fractal theory
摘要
Abstract
In view of the deteriorating urban ecosystem, a combination of landscape pattern index, water environment parameters, and socio-economic indicators was adopted to build an urban ecosystem health assessment index system. Based on self-similarity theory and fractal theory, the system fractal dimension was calculated, and the link between the fractal dimension and ecosystem health was set up to quantitatively evaluate the urban ecosystem health status and analyze its dynamic trend at different stages of urbanization. By analyzing and calculating the ecosystem fractal dimension of Huzhou City in 1997, 2001 , and 2005, the fractal dimensions in the three years were obtained, which were 0.8934, 1. 1723, and 1.2619, respectively, foreshowing that the urban ecosystem of the City was growing towards an unhealthy condition. This study indicated that the development of Huzhou City' s urbanization had made a negative effect on the urban ecosystem, and thus, more attention should be paid to the ecological and environmental protection during urban planning and construction in the future.关键词
