Abstract: In order to effectively assess the ecological security status of Hubei province from 2014 to 2018,10 major cities in Hubei province were selected as the research objects for empirical study.Combined with the ecological characteristics of the urban agglomeration in the middle reaches of the Yangtze River,based on the pressure-state-response model,13 indicators including the natural population growth rate,the comprehensive utilization rate of solid waste and the proportion of the tertiary industry in the regional GDP were selected to construct the ecological security index system of Hubei province.The weight of each indicator was determined by principal component analysis.The comprehensive index method and comprehensive evaluation model were used to evaluate the ecological security status of Hubei province,and based on the evaluation results,suggestions for promoting the high- quality development of Hubei province were put forward.
