Abstract:: According to P—S—R model and entropy weight method, an index system was constructed and the weight was obtained. By using the RS images in 1991, 2001 and 2007, the social, economic and field survey data and fuzzy matter element analysis method, the urban eco-security of Siping city was evaluated. The result showed that: (1) the eco-security situation was unstable, and had a transformation from insecurity to critical security from 1991 to 2007; (2) the urbanization rate, per capita GDP, energy consumption amount per 10⁴ Yuan GDP, etc. had security status to urban eco-security, while these indices, such as per capita road area, the compactness degree of construction area, public transit vehicle amount per 10⁴ people and the green coverage rate of construction area had the state of insecurity; (3) in order to continue to improve the environmental protection consciousness, change the economic growth way, increase investment in science and technology, optimize industrial structure, increase the per capita public green land area and public transportation vehicles, raise land utilization rate, so as to realize the collaborative unity of economic benefits, environmental benefits and social benefits is the main development direction.
