【摘要】：以鄱阳湖区为研究对象,结合鄱阳湖区特征及生态建设需求,在遵循评价指标选取原则的基础上,初步建立了反映鄱阳湖区自然地理状态、社会经济特征、水环境特征、水生态特征、政府管理等综合功能特征的主要指标。通过对鄱阳湖区的水文、工程、生态、经济社会资料进行了调查研究。运用定量遥感方法反演鄱阳湖流域相关的水量、水质和生态环境特征参量,建立长时间序列的生态环境特征参数,综合分析鄱阳湖区生态系统特征。分析鄱阳湖区生态系统面临的主要问题,有针对性地提出了生态系统调控对策。为解决维持和增强鄱阳湖区生态系统的结构和功能、增大生态系统的负荷能力、保证生态系统服务功能的正常发挥提供全方位的数据支持。
[Abstract]:Taking Poyang Lake region as the research object, combined with the characteristics of Poyang Lake region and the needs of ecological construction, on the basis of following the principle of evaluation index selection, this paper preliminarily established the natural geographical state and social and economic characteristics of Poyang Lake region. Water environment characteristics, water ecological characteristics, government management and other comprehensive functional characteristics of the main indicators. Through the Poyang Lake region hydrology, engineering, ecology. The quantitative remote sensing method was used to retrieve the relevant parameters of water quantity, water quality and ecological environment in Poyang Lake basin, and to establish the ecological and environmental characteristic parameters of a long time series. Comprehensive analysis of the characteristics of the Poyang Lake region ecosystem and analysis of the main problems faced by the Poyang Lake region ecosystem. In order to maintain and strengthen the structure and function of the ecosystem in Poyang Lake region, the paper puts forward the countermeasures of ecosystem regulation and control, and increases the load capacity of the ecosystem. Ensure that ecosystem services function to provide a full range of data support.
