摘要
在生态安全评价压力-状态-响应概念模型指导下,以青岛市为研究区,从水土保持角度,综合运用熵权法和GIS的先进技术,进行了青岛市生态安全评价研究。研究表明,青岛市的生态安全表征状态以一般为主,生态安全水平有待进一步提高。在分析的基础上,提出了青岛市生态安全的发展模式,为青岛市控制水土流失、建设良好生态提供依据。
In this research the Entropy Method and GIS＇ advanced technology was applied to study the ecological security from the angle of soil and water conservation,based on the Qingdao being taken as the investigation region under the guidance of model of ecological security evaluation,rankly,State-Pressure-Response. The results showed that the level of ecological security was mainly about general which accounted for 39.96% of the total investigation region. Based on the analysis,the development mode of ecological security was epurated to provide the evidence for controlling soil erosion for the construction of a good ecology in Qingdao.
