摘要
以青岛市为研究区,基于PSR模型构建土地生态安全评价指标体系,采用熵权法和综合评价法,对2017年青岛市土地生态环境安全状况进行综合评价,并结合评价结果进行区域等级划分。结果表明:青岛市的7区3市中,土地生态安全状况存在一定差异。市南区、市北区和李沧区处于土地生态安全状况的风险级别;崂山区、黄岛区、即墨区、平度市和莱西市处于敏感级别,但彼此之间的差异并不明显;只有城阳区的土地生态安全为良好级别。建设针对不同级别土地生态安全的状况,从人口、产业、政策及社会方面进行改进,有助于青岛市土地生态环境安全的保护。
Scientific and rational evaluation of land ecological security is an important part of ecological civilization construction and is of great significance to the sustainable development of ecological environment.Based on the PSR model, this paper builds a land ecological security evaluation index system.And uses the entropy weight method and the comprehensive evaluation method to comprehensively evaluate the land ecological environment safety status of Qingdao in 2017, and combine the evaluation results to carry out regional grades.The results show that there are certain differences in the ecological security status of the land in the 7 districts and 3 cities of Qingdao.Shinan District, Shibei District and Lisong District are at the risk level of land ecological security.Laoshan District, Huangdao District, Jimo District, Pingdu City and Laixi City are at a sensitive level, but the differences between them are not obvious.Only the ecological security of the land in Chengyang District is at a good level.In view of the ecological security status of different levels of land, improvement from population, industry and policy will contribute to the protection of land ecological environment security in Qingdao.
