山东半岛蓝色经济区生态安全预警时空格局研究

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,用熵权法进行研究,从时间看,2005—2013年该地区的生态环境得到改善,但还没有出现V级理想状态的地区;从空间看,到2013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、沾化和西南的日照值得关注。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。

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

This paper takes the Blue Economic Zone of Shandong Peninsula as a whole to study.The PSR model was used to construct ecological security early warning index system of the Blue Economic Zone of Shandong Peninsula.Then the pa-per studies the ecological security early warning of the Blue Economic Zone of Shandong Peninsula by entropy method.The main conclusions are as follows:From the time perspective,the ecological environment in the region has made preliminary improvement in 2005 -2013 years,but no area reaches V grade that is the ideal state level;From the space perspective, the ecological environment of the eastern part of Shandong Peninsula Blue Economic Zone is better than the western part. Especially,supervision departments need to pay attention to Wudi,Zhanhua in the northwest and the Rizhao in the South-west.Finally,According to the different regions with different levels of ecological security,the paper puts forward the cor-responding ecological restoration and environmental governance countermeasures.
