摘要
为揭示黄土高原生态保护时空演变规律,以黄土高原为研究对象,构建生态保护评价指标体系,采用熵值法和空间自相关方法,探究2011年-2018年黄土高原生态保护时空演变特征。黄土高原生态保护等级在2011年-2018年间持续上升,在2012年出现明显的空间聚集特征。2011年黄土高原生态保护指数处于[0.030,0.351],到2018年生态保护指数达到[0.045,0.639],生态保护指数明显提升,西安、郑州等城市进入中等质量发展和较高质量发展阶段,其余城市仍为低质量发展阶段。
In order to reveal the spatio-temporal evolution rules of ecological protection in the Loess Plateau,an ecological protection evaluation index system was constructed using the Loess Plateau as the research object,and the entropy method and spatial autocorrelation method were used to explore the spatio-temporal evolution characteristics of ecological protection in the Loess Plateau from 2011 to 2018.The results show that the ecological protection level of the Loess Plateau continued to rise between 2011 and 2018,and obvious spatial aggregation characteristics appeared in 2012.In 2011,the ecological protection index of the Loess Plateau was[0.030,0.351].By 2018,the ecological protection index reached[0.045,0.639].The ecological protection index increased significantly.Cities such as Xi'an and Zhengzhou entered the stage of medium-quality development and higher-quality development.The rest cities are still in a low-quality development stage.
