- Abstract:
- Based on the analysis of human habitat ecosystem structure, the indicator system of evaluating sustainable development ability of human habitat ecosystem was set up through dissipative structure theory and entropy change theory. The year-based information entropy model and index-based information entropy model were applied to evaluate the evolution direction and health coordination of human habitat ecosystem. The correlation degree between index and aggregative indicator was analyzed by grey correlation degree. The results show that:from 2005 to 2015, the input-output entropy, metabolism entropy production and total entropy of the human habitat ecosystem in the lower Yangtze region presented the wavelike decrease change, the order degree kept improving. The comprehensive development degree of the lower Yangtze region went down at first and then went up, the whole state was getting better. The coordinated development degree went up at first, and then went down, and transformed from environmental lag type to economic lag type. In the future, the research area will focus on increasing local fiscal revenue, developing new energy sources, adjusting consumption structure, controlling urban sewage and industrial waste gas, and increasing the proportion of investment in environmental protection. This research method can reflect the evolution direction and trend of human habitat ecosystem and propose targeted measures to enhance the sustainable development ability of the system.
