基于层次分析法的鹤岗市煤矿区生态脆弱性评价
Ecological Vulnerability Assessment Based on Analytic Hierarchy Process in Hegang Coal Mining Area
摘要
Abstract
Based on the theory of ecological vulnerability of domestic and foreign coal mining areas, the 3S technology was adopted in coal mining area of Hegang City.From the three properties of environmental exposure, sensitivity and adaptability, ecological vulnerability model and evaluation index system were established in coal mining area in Hegang City based on hierarchical analysis method and expert consultation method.Results showed that among the influencing factors of ecological vulnerability in coal mining area, suitability had greater impacts on environmental exposure and sensitivity, indicating that ecological environment was greatly affected by external disturbance.In the ten indexes of influencing factors, vegetation coverage rate had the greatest weight (significant influence), followed with the percentage of cultivated land area.Therefore, reducing human interference, increasing vegetation coverage and the proportion of arable land were not only simply the best choice for ecological construction of coal mining area, but also the foundation of sustainable economic development.关键词
