摘要: 以现代黄河三角洲所在东营市的4个区县(东营区、河口区、垦利区和利津县)为研究对象,采用驱动力-压力-状态-响应-影响(DPSIR)模型,基于该区独特的生境特征,筛选出人口密度、黄河来沙、自然岸线率等14个指标,构建了黄河三角洲生态质量评价体系,利用熵权法确定各指标权重;采用综合指数法,计算2000—2020年黄河三角洲各区县的生态质量评价综合指数,并分析其主要驱动因子。结果表明:现代黄河三角洲的生态质量评价综合指数2000—2010年呈下降趋势,2010—2020年呈上升趋势,垦利区的生态质量最好,东营区的生态质量最差;人口密度、还湿面积和湿地保护率是影响现代黄河三角洲生态质量的首要因子,指标层中状态、影响和响应指标对现代黄河三角洲湿地生态质量有很大影响;不同区县生态质量提升的主要驱动因子不同,东营区和利津县均为人口密度,河口区为还湿面积,垦利区为人口密度和湿地率。本研究为黄河三角洲的生态保护与修复提供了一定的科学依据。

Abstract: We assessed the ecological quality of four districts/counties in Dongying City (Dongying District, Hekou District, Kenli District and Lijin County) located in the Yellow River Delta. An ecological quality evaluation system was established with DPSIR model by identifying 14 indicators, including population density, sediment flux, and natural shore-line rate. The weight of each indicator was calculated by the entropy weight method. Using a comprehensive index approach, we analyzed the dynamics of ecological quality assessment index and its driving factors for each district/county from 2000 to 2020. The comprehensive index for ecological quality assessment of the modern Yellow River Delta decreased in 2000-2010 and increased in 2010-2020. Kenli District demonstrated superior ecological quality, while Dongying District showed inferior performance. Population density, area of wetland restoration, and wetland protection rate were key factors influencing the ecological quality. State, influence, and response indicators had significant impacts on wetland ecological quality. Different districts/counties exhibited different driving factors for improving ecological quality, such as population density for Dongying District and Lijin County, area of wetland restoration for Hekou District, and population density and wetland rate for Kenli District. Our results provide a scientific foundation for ecological protection and restoration in the Yellow River Delta.
