山东半岛蓝色经济区生态安全预警时空格局研究

Study on Spatiotemporal Change of Ecological Security Early Warning in the Blue Economic Zone of Shandong Peninsula

摘要:

生态安全是人类社会可持续发展的核心,已成为多个学科的研究热点。以山东半岛蓝色经济区整体为研究对象,采用PSR模型构建生态安全预警指标体系,并用熵权法对山东半岛蓝色经济区生态安全预警进行研究,得出以下结论：从时间维度看,2005-2012年该地区的生态环境得到了初步改善,但是还没有出现进入V级理想状态的地区；从空间格局看,到2012年,山东半岛蓝色经济区的生态环境为“东优西劣”,特别是西北的无棣、沾化和西南的日照需要继续关注。最后针对处于不同生态安全等级的地区提出相应的生态恢复和环境治理对策。

Abstract:

Ecological security is the core of the sustainable development of human society; it has become a hotspot in many disciplines. This paper takes the Blue Economic Zone of Shandong Peninsula as a whole to study. The PSR model was used for constructing ecological security early warning index system of the Blue Economic Zone of Shandong Peninsula. Then the paper study on ecological security early warning of the Blue Economic Zone of Shandong Peninsula by entropy method. The main conclusions are as follows: From the time,The ecological environment in the region has been preliminary improvement in 2005-2012 years, but no area reaches V grade that is the ideal state level. From space, the ecological environment of the eastern part of Shandong Peninsula Blue Economic Zone is better than the western part. Especially supervision department need to continue to pay attention to Wudi, Zhanhua in the northwest and the Rizhao in the Southwest. Finally, According to the different regions have different levels of ecological security, the paper puts forward the corresponding ecological restoration and environmental governance countermeasures.
