摘要
[目的]分析2000—2020年中原城市群“三生”用地的时空演变特征及其生态环境效应,为快速城镇化地区“三生”空间格局优化以及区域生态环境保护等提供科学参考。[方法]基于中原城市群2000,2010和2020年3期土地利用数据,采用生态环境质量指数和景观格局指数两种方法,定量分析中原城市群“三生”用地转型的生态环境效应。[结果]①研究区生产用地面积明显减少(-7890 km^(2)),生态用地面积相对稳定(仅变化0.1%),生活用地面积快速增加(7638 km^(2));2000—2010年的“三生”用地转换面积远低于2010—2020年。②研究区生态环境质量指数先升后降,在区域整体上呈现“西高东低”的空间格局。郑州市下降幅度最大,济源市提高最多;生态环境质量指数(EV)与最大斑块指数(LPI)、景观形状指数(LSI)、斑块结合度指数(COHESION)、聚集度指数(AI)、香农多样性指数(SHDI)和香农均匀性指数(SHEI)高度相关。③生态环境改善趋势小于恶化趋势,恶化的主要因素为林草生态用地向农业生产用地转化,以及生活用地对农业生产用地的占用。④各类景观破碎化加剧,聚集度和连结度降低,景观形状趋于不规则化,多样性和均匀度增加,整体生态环境质量恶化。[结论]两种评价指数对“三生”用地转型的生态环境效应评价结果趋于一致,即研究区生态环境质量呈下降趋势。农业生产用地对林地和草地生态用地的占用是生态环境恶化的主要因素。
[Objective]The temporal and spatial evolution characteristics of the productive-living-ecological land use and its ecological environmental effects in the Central Plains urban agglomeration from^(2)000 to 2020 were analyzed in order to provide references for the optimization of the productive-living-ecological space pattern in rapidly urbanized areas and for regional ecological environmental protection.[Methods]Based on land use data of the Central Plains urban agglomeration in 2000,2010,and 2020,the ecological environmental quality index and the landscape pattern index were used to quantitatively analyze the ecological environmental effects of the productive-living-ecological land use transition in the Central Plains urban agglomeration.[Results]①The area of production land in the study area decreased significantly(-7890 km^(2)),the area of ecological land was relatively stable(changing only 0.1%),and the area of living land increased rapidly(7638 km^(2)).The conversion of productive-living-ecological land use from^(2)000 to 2010 was much lower than in 2010—2020.②The eco-environmental quality index of the study area initially rose and then fell,showing an overall spatial pattern of“high in the west and low in the east”.Zhengzhou City had the largest decline,and Jiyuan City increased the most.LPI,LSI,COHESION,AI,SHDI were highly correlated with EV.③The improvement trend of the ecological environment was less than the deterioration trend.The main factors causing deterioration were the conversion of forest and grass ecological land to agricultural production land and the occupation of agricultural production land by living land.④The fragmentation of various landscapes increased over time,and the degree of aggregation and connection decreased over time.The shape of the landscape tended to become irregular,the diversity and uniformity have increased,and the overall ecological environmental quality deteriorated.[Conclusion]The evaluation results of the eco-environmental effects of the two evaluation inde
