摘要
研究目的:构建统一有效的生态产品价值核算方法体系,识别黄河三角洲生态产品价值的空间分布及动态变化,为生态产品价值实现路径和生态损害鉴定赔偿制度提供参考。研究方法:基于卫星遥感数据,采用生态过程模型和能值分析法。研究结果:(1)2000—2020年黄河三角洲生态产品价值增长了125.39%,其中物质供给与调节服务占比下降,文化服务占比上升。(2)从各项指标来看,水质净化和碳储量服务的价值下降;水源涵养与碳储量服务的实物量呈现下降趋势;粮食生产产品和碳储量服务的能值下降;其他指标的实物量、能值、价值均呈现增长趋势。(3)黄河三角洲生态产品价值呈现出“中部高、东北低”的空间格局,并表现出“中部区域向四周逐渐递减”的变化趋势;其中,粮食生产产品、水产养殖和休闲游憩服务高价值区域分别集中分布于黄河两岸、沿海地带和黄河入海口;水源涵养和水质净化服务呈现“中部高、沿海地区低”的空间特征;土壤保持和碳储量服务均呈现出“中部升高”的动态特征。研究结论:基于卫星遥感数据、生态过程法与能值法相结合的生态产品价值核算方法体系可显著提升生态产品价值评估的客观性和实效性,有助于推动黄河三角洲生态产品价值实现及生态补偿和生态环境损害赔偿政策的有效实施。
The purpose of this study is to establish a unified and effective methodology for valuing ecological products,and identifying their spatial distribution and temporal dynamics,to provide insights for pathways that realize ecological product values and ecological damage compensation systems.The research methods include ecological process model and emergy analysis based on remote sensing data.The research findings are as follows:1)the ecological product value of the Yellow River Delta increased significantly from 2000 to 2020,with a growth rate of 125.39%.The proportion of material supply and regulatory services decreased,while that of cultural services increased.2)In terms of individual indicators,the values of water purification and carbon storage decreased;the physical quantities of water conservation and carbon storage showed a downward trend;the emergy and value of crop production and carbon storage declined;the other physical quantity,emergy,and value indicators showed growth trends.3)Spatially,the ecological product value exhibits a“high in the middle,low in the northeast”pattern,with a gradient decrease from the central region to the periphery.Highvalue areas for grain production,aquaculture and recreational services are concentrated along the Yellow River banks,coastal areas and the river’s mouth.Water conservation and water purification services show a“high in the middle,low in coastal areas”spatial characteristic.Both soil conservation and carbon storage services demonstrate a dynamic increase towards the central region.In conclusions,the combined methodology of satellite remote sensing data,ecological process models and emergy analysis significantly improves the objectivity and practicality of ecological product value assessment,which facilitates the realization of ecological product values in the Yellow River Delta and the effective implementation of ecological compensation and environmental damage compensation policies.
