| 摘 要： | 矿业城市生态脆弱性具有典型的"压力-敏感-弹性"(PSE)特征,据此构建了基于生态压力、生态敏感及生态弹性指数的矿业城市生态脆弱性评价的基本判定指标和评价模型,进而比较选取熵值法为评价方法,使之形成一套相对完整的矿业城市生态脆弱性评价体系,并以阜新市为例,进行矿业城市生态脆弱性评价。结果表明:①阜新市生态脆弱性随矿产资源开采阶段的演进而呈明显的上升趋势;②生态敏感度对阜新市生态脆弱性具有决定性意义;③阜新市生态脆弱性演变规律表明矿业城市生态脆弱性在"锁定效应"和累积因果循环作用下具有典型的时间累积性,侧面说明阜新市要实现可持续发展产业转型是关键、生态补偿是措施、资金是保障,从而需要加大中央和上级政府在财政、金融、产业、税收等方面的优惠政策和扶持力度。

| Abstract: | Mining city,as an important part of urban system,is always a focus question in relation to social stability and development of the national economy.The ecological fragility of the mining city has the typical characteristics of pressure-sensitive-elasticity(PSE).Hereby,this paper establishes an evaluation model of ecological fragility of the mining city,taking ecological pressure index,ecological sensitivity index,ecological elasticity index as the basic indexes and utilizing an relatively reasonable evaluat... |
