加快建设生态友好的现代化新青海是青海省实现现代化的重点内容.文中综合运用土地利用转移矩阵、生态环境质量指数、重心迁移分析、标准差椭圆、地理探测器模型探讨了青海省1990-2020年生态友好等级区时空演变特征及影响因素.结果表明:1)青海省生产空间面积从1990年的8304.48km2上升至2020年的9528.19km2;生态空间面积总量相对稳定,保持在71万km2左右;生活空间面积增加迅速,至2020年增加到992.82km2.2)青海省生态友好状况不断向好,全省生态环境质量指数从0.2731上升至0.2903,各市州生态环境质量呈波浪式上升趋势.3)各等级区呈由东南向西北迁移趋势,到2020年生态友好高质量区、较高质量区面积分别为95152.38km2、133817.54km2,分别占比13.17％、18.53％.4)年均降水量是影响青海省生态友好等级区演化的核心因子,其次是户籍人口城镇化率和距市县政府驻地距离,年均降水量与距市县政府驻地距离交互对生态友好等级区空间分异的影响较强.
Identification,spatial-temporal evolution,and geographical exploration of eco-friendly areas in Qinghai Province:A perspective of production-living-ecological spaces
Accelerating the construction of eco-friendly modern Qinghai is the key content of realizing modernization.In this paper we comprehensively used research methods such as land use transfer matrix,ecological environment quality index,analysis of the center of gravity transfer,standard deviation ellipse,and geographic detector model,to explore the characteristics of eco-friendly area evolution in Qinghai Province from 1990 to 2020 and influencing factors.The results show that:1)The area of production space in Qinghai Province increased from 8304.48km2 in 1990 to 9528.19km2 in 2020,the area of total ecological space was relatively stable at about 710000km2,and the area of living space increased to 992.82km2 by 2020.2)The ecological friendliness situation in Qinghai Province continued to improve.The ecological environment quality index of the whole province increased from 0.2731 to 0.2903.The ecological environment quality of all cities and states showed a wavy upward trend.3)Each grade area showed a trend of migration from southeast to northwest.By 2020,the area of eco-friendly highest quality areas and higher quality areas were 95152.38km2 and 133817.54km2,respectively,accounting for 13.17％and 18.53％,respectively.4)The average annual precipitation was the core factor affecting the evolution of eco-friendly areas in Qinghai Province,followed by the urbanization rate of the registered population and the distance from the city and county governments.The interaction between the average annual precipitation and the distance between the city and county governments had a stronger impact on the spatial differentiation of eco-friendly areas.
