基于突变级数法的闽南海岸带生态安全评价
Eco-security assessment in southern coastline of Fujian based on catastrophe theory
摘要
Abstract
Based on P-S-R framework and catastrophe progresion method, a catastrophe model for assessment of urban eco-security was developed, and assessed the ecological security status of southern coastline of Fujiann from 1994 to 2006. The results showed that: ( 1 ) With the impact of rapid urbanization and population growth, the ecolosical security gained in 2001, and returned to V again in 2006. The system pressure increased, because human activities created a sisnifieant load. (2) From 1994 to 2006, the values of tie eeoIogical security of the system state and system response were rising, indicating that people's response to system safety was positive and effective. However, poulation and resource pressure were the main threat to ecological security of the study area. (3) Catastrophe theory which did not use weights prevened people from subjectivity when empowering. Using catastrophe model to calculate specific value of various indicators of the ecological security, quantitative contrast can be conducted anong all levels of various indicators.关键词
