摘　　要：研究不同时期土地利用方式对生境质量的影响,对于矿业城市健康可持续发展具有重要意义。选择安徽省淮南市为研究对象,利用2000-2020年的三期土地利用数据作为基础数据,采用InVEST模型,分析了2000-2020年研究区生境质量的分布规律与变化特征。结果表明:(1)近20年来,研究区主要以水田和旱地2种土地利用类型为主,在研究期间占研究区总面积均超过70%。2000-2020年的用地类型变化剧烈,综合土地利用动态度为4.63%,研究区内的水田和旱地面积逐年递减,占比减少了4.3%,坑塘和建设用地的面积呈逐年增长趋势,坑塘和建设用地的面积占比分别增加0.4%、4.21%;(2)2000-2020年的生境质量平均值分别为:0.37、0.36、0.35,表明研究区生境质量呈持续下降趋势。研究结果可为研究区域生境土地综合整治及生态规划提供参考。Studying the impact of land use patterns on habitat quality in different periods is of great significance for the healthy and sustainable development of mining cities.This paper selects Huainan City,Anhui Province as the research object,uses three phases of land use data from 2000 to 2020 as the basic data,and uses the InVEST model to analyze the distribution and change characteristics of habitat quality in the study area from 2000 to 2020.The results show that:①In the past 20 years,the research area mainly consists of two types of land use:paddy field and dry land,accounting for over 70% of the total area of the research area during the research period.The land use types have undergone significant changes from 2000 to 2020,with a comprehensive land use dynamic degree of 4.63%.The area of paddy fields and dry lands in the study area has been decreasing year by year,with a decrease of 4.3%.The area of ponds and construction land has shown an increasing trend year by year,with an increase of 0.4% and 4.21%,respectively;②The average habitat quality values between 2000 and 2020 were 0.37,0.36,and 0.35,respectively,indicating a continuous downward trend in the habitat quality of the study area.Among them,5.24% of the habitat quality levels decreased,transitioning from lower-to-lower levels.The research results provide scientific references for the comprehensive improvement of habitat land and ecological planning in the research area.
