利用P—S—R模型构建指标体系,采用熵权法求取权重,基于吉林省四平市模糊物元模分析方法,利用1991年、2001年和2007年的3期TM遥感影像,结合野外调查数据及社会经济数据等,分析处理提取生态安全评价指标,对四平市的生态安全进行评价。结果表明:(1)四平市1991—2007年城市生态安全状况是不稳定的,经历了由“不安全”向“临界安全”转化的过程;(2)影响四平市城市生态安全的因素并不协调统一,其中,城市化率、人均GDP、万元GDP能耗、恩格尔系数等指标为安全状态,而人均道路面积、建设区紧凑度、每万人拥有公共交通车辆、建设区绿化覆盖率等指标为不安全状态;(3)四平市在今后的发展中,要继续提高环境保护意识,转变经济增长方式,加大科技投入,优化产业结构,增加人均公共绿地面积和公共交通车辆,提高土地利用率,从而实现经济效益、环境效益和社会效益的协调统一。

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.
