| 中文摘要: |
| 为科学、准确地评估区域生态质量,促进生态保护与修复,以江苏省为研究对象,综合运用卫星遥感、生物多样性调查等多源数据,根据《区域生态质量评价办法(试行)》对2020—2024年江苏省生态质量情况开展评估,并进一步从生态格局、生态功能、生物多样性和生态胁迫4个维度分析变化趋势及其驱动因素。结果表明:①2020—2024年,江苏省生态质量保持为"二类",年际间变化幅度为"基本稳定"。受自然生态系统覆盖比例低、国土空间开发强度高等因素制约,江苏省生态格局指标和生态胁迫指标有待优化。②全省生态质量变化受建设用地扩张、生态用地减少、城市公园绿地增加、生物多样性指标提升和植被覆盖年际波动等多重因素综合影响。③稳定生态格局和生态胁迫,提高生态功能和生物多样性,是进一步稳定和提升江苏省生态质量的关键。 |

| To scientifically and accurately assess the ecological quality and facilitate regional ecological conservation and restoration,taking Jiangsu as the research area,using multi-source data including satellite remote sensing and biodiversity surveys,this study applied the Trial Measures for Regional Eco-environmental Quality Evaluation to evaluate the ecological quality of Jiangsu Province from 2020 to 2024.Trends and driving factors were analyzed across four dimensions:ecological pattern,ecological function,biodiversity,and ecological stress.The results showed that:① From 2020 to 2024,the Ecological Quality Index (EQI) of Jiangsu Province maintained "Class II",with an annual change range of "basically stable".Constrained by factors such as a low proportion of natural ecosystem coverage and a high intensity of territorial space development,the ecological pattern indicators and ecological stress indicators of Jiangsu Province need to be optimized.②Provincial ecological dynamics were driven by multiple interacting factors,including construction land expansion,ecological land reduction,urban park green space increase,biodiversity index improvement,and interannual vegetation coverage fluctuation.③Stabilizing the ecological pattern and ecological stress,and improving ecological functions and biodiversity are the keys to further stabilizing and enhancing the ecological quality of Jiangsu Province. |
