| 融合多源遥感影像与地面实测数据,构建"天空地"一体化监测网络,严格依据《区域生态质量评价办法(试行)》,选取长株潭都市圈这一中部核心区域,从生态格局、生态功能、生物多样性和生态胁迫4个维度,对长株潭都市圈生态质量现状及其动态变化进行综合剖析。研究发现,2024年长株潭都市圈生态质量为65.35,属二类,具有良好的生态基底,研究区内生态质量达到一类、二类、三类和四类的县域评价单元占比分别为10.5%、36.8%、47.4%和5.3%,一、二类面积总和占比高达84.6%;同时,区域生态质量呈现显著的空间分布差异特征,与都市圈外围县域相比,城市建成区的生态质量则较差。2020年以来,区域内生态质量轻微改善的县域共6个,覆盖区域面积的12.21%,生态质量保持基本稳定的县域为13个,占比高达87.79%,长株潭都市圈生态质量整体呈现稳中有升、持续向好的态势。 |

| As a key strategic pivot driving the coordinated development of the Yangtze River Economic Belt and a core engine spearheading the rise of central China,the Changsha-Zhuzhou-Xiangtan Metropolitan Circle faces heightened ecological demands due to its rapidly expanding regional economy.Scientifically evaluating its ecological quality serves not only as a practical embodiment of the "lucid waters and lush mountains are invaluable assets" concept,but also as a significant innovation in exploring synergistic models for new urbanization and ecological civilization construction.This study integrates multi-source remote sensing imagery and ground-based measured data to establish an integrated "space-air-ground" monitoring network.Strictly adhering to the Technical Criterion for Regional Eco-Environmental Quality Evaluation (Trial),it comprehensively deconstructs and analyzes the current status and dynamics of ecological quality within the metropolitan circle across four core dimensions: ecological pattern,ecological function,biodiversity,and ecological stress.The study found that in 2024,the ecological quality index of the Changsha-Zhuzhou-Xiangtan Metropolitan Circle was 65.35,classified as Grade II,indicating a sound ecological foundation.Among the county-level evaluation units in the study area,the proportions classified as Grade I,II,III,and IV were 10.5%,36.8%,47.4%,and 5.3% respectively,with Grade I and II areas covering a substantial 84.6% of the total area.Meanwhile,the regional ecological quality exhibited distinct spatial heterogeneity,with urban built-up areas exhibiting poorer quality compared to surrounding counties.Since 2020,six counties in the region have experienced slight improvements in ecological quality,covering 12.21% of the area,while ecological quality remained essentially stable in 13 counties,accounting for 87.79% of the region.Overall,the ecological quality of the area demonstrates a trend of stability with slight improvement,continuing to move in a positive direction. |
