摘要
以贵州省黔中地区33个县(市、区)为研究单元,基于2000年、2010年和2020年三期土地利用现状数据,按照"生产—生态—生活"土地利用功能分类,利用土地利用转移矩阵对黔中地区的土地利用功能转型进行研究,同时通过计算生态环境质量指数和土地利用转型生态贡献率,定量分析黔中区生态环境效应。研究表明,2000-2020年,黔中区生产用地和生态用地面积分别减少5911.75 hm^(2)和18902.59 hm^(2),生活用地面积增加24814.33 hm^(2);黔中区生态环境质量指数从2000年的0.6178下降到2020年的0.6147,生态环境质量呈下降趋势;黔中区生态环境改善和恶化两种情况同时存在,但是生态环境恶化的趋势稍大于生态环境改善趋势。
To 33 in Central Guizhou in Guizhou County(city,area)as the research unit,based on the land use status data of 2000,2010 and 2020,remote sensing monitoring of land use in accordance with the"production,ecology,life"function classification,by using the transfer matrix of land use on the function of land use transition in Central Guizhou,at the same time,through the calculation of the ecological environment quality index and ecological contribution rate of land use transformation,the quantitative analysis of Central Guizhou ecological environment effect.The research shows that,from 2000 to 2020,the area of production land and ecological land in Central Guizhou decreased by 5911.75 hm^(2) and 18902.59 hm^(2) respectively,and the area of living land increased by 24814.33 hm^(2);the ecological environment quality index of Central Guizhou decreased from 0.6178 in 2000 to 0.6147 in 2020,indicating a downward trend in ecological environment quality;both the ecological environment improvement and the ecological environment deterioration existed in Central Guizhou,but the trend of the ecological environment deterioration was slightly larger than the trend of the ecological environment improvement.
