发布时间:2018-11-11 19:35
【摘要】:河流不但为人类提供了丰富地淡水资源,且对维持生态系统健康安全起到至关重要。然而由于人类对河流水资源的过度开发利用,导致河流生态系统遭受破坏,生态服务功能受到威胁,生态服务价值大打折扣。因此,维护河流生态服务功能、维持河流生态服务价值等具有重要意义。本文基于河流水文-生态影响机制探讨了河流生态服务价值与水文-生态影响机制的响应关系,并以东江流域为案列,对河流生态服务价值与水文-生态影响机制的响应关系进行了应用研究。研究成果和结论如下:1)通过介绍河流水文和生态因子的内涵,分析了河流水文因子与生态因子的变特征,并从定性角度探讨了河流水文因子与生态因子的相互影响关系,定量角度揭示出了河流水文-生态之间的相互影响机制。2)基于前人对河流生态服务功能类型划分的研究成果,阐述了河流生态服务价值的类型划分、评价方法、评价步骤;定性分析了河流生态服务价值与其水文-生态影响机制的响应关系,构建了河流生态服务价值与其水文-生态影响机制的响应关系数学模型,定量计算出了河流生态服务价值与其水文-生态影响机制的响应关系。3)通过对东江流域水文与生态数据资料,采用小波分析和水文统计分析计算方法分析了东江流域的水文因子与生态因子的变化规律,应用多元回归分析与主成分分析方法定量分析了东江流域的水文-生态影响机制,分析计算了东江流域生态服务价值与水文因子及生态因子之间的响应关系,推出了东江流域水文-生态影响机制与生态服务价值的响应关系函数表达式;并对结果进行综合分析。
[Abstract]:Rivers not only provide people with abundant fresh water resources, but also play an important role in maintaining ecosystem health and safety. However, due to the over-exploitation and utilization of river water resources, the river ecosystem is destroyed, the ecological service function is threatened, and the value of ecological service is greatly reduced. Therefore, it is of great significance to maintain river ecological service function and maintain river ecological service value. Based on the mechanism of river hydrology and ecological impact, this paper discusses the response relationship between river ecological service value and hydrology ecological impact mechanism, and takes Dongjiang River Basin as a case study. The response relationship between river ecological service value and hydrology-ecological impact mechanism is studied in this paper. The research results and conclusions are as follows: 1) by introducing the connotation of river hydrological and ecological factors, the variable characteristics of river hydrological factors and ecological factors are analyzed, and the interaction between river hydrological factors and ecological factors is discussed from the qualitative point of view. The interaction mechanism between river hydrology and ecology is revealed quantitatively. 2) based on the previous researches on the classification of river ecological service function, the classification, evaluation methods and steps of river ecological service value are expounded. The response relationship between river ecological service value and its hydro-ecological impact mechanism is analyzed qualitatively, and a mathematical model of river ecological service value and its hydro-ecological impact mechanism is established. The response relationship between the value of river ecological service and its hydro-ecological impact mechanism is calculated quantitatively. 3) based on the hydrological and ecological data of Dongjiang River Basin, The variation laws of hydrological and ecological factors in Dongjiang River basin were analyzed by wavelet analysis and hydrological statistical analysis. The hydrological and ecological influence mechanism of Dongjiang watershed was quantitatively analyzed by using multivariate regression analysis and principal component analysis. The response relationship between ecological service value, hydrological factors and ecological factors in Dongjiang river basin is analyzed and calculated, and the expression of response function between hydrology and ecological impact mechanism and ecological service value in Dongjiang river basin is derived. The results are analyzed synthetically.
