【摘要】：河流不但為人類提供了豐富地淡水資源,且對維持生態(tài)系統(tǒng)健康安全起到至關(guān)重要。然而由于人類對河流水資源的過度開發(fā)利用,導致河流生態(tài)系統(tǒng)遭受破壞,生態(tài)服務(wù)功能受到威脅,生態(tài)服務(wù)價值大打折扣。因此,維護河流生態(tài)服務(wù)功能、維持河流生態(tài)服務(wù)價值等具有重要意義。本文基于河流水文-生態(tài)影響機制探討了河流生態(tài)服務(wù)價值與水文-生態(tài)影響機制的響應(yīng)關(guān)系,并以東江流域為案列,對河流生態(tài)服務(wù)價值與水文-生態(tài)影響機制的響應(yīng)關(guān)系進行了應(yīng)用研究。研究成果和結(jié)論如下:1)通過介紹河流水文和生態(tài)因子的內(nèi)涵,分析了河流水文因子與生態(tài)因子的變特征,并從定性角度探討了河流水文因子與生態(tài)因子的相互影響關(guān)系,定量角度揭示出了河流水文-生態(tài)之間的相互影響機制。2)基于前人對河流生態(tài)服務(wù)功能類型劃分的研究成果,闡述了河流生態(tài)服務(wù)價值的類型劃分、評價方法、評價步驟;定性分析了河流生態(tài)服務(wù)價值與其水文-生態(tài)影響機制的響應(yīng)關(guān)系,構(gòu)建了河流生態(tài)服務(wù)價值與其水文-生態(tài)影響機制的響應(yīng)關(guān)系數(shù)學模型,定量計算出了河流生態(tài)服務(wù)價值與其水文-生態(tài)影響機制的響應(yīng)關(guān)系。3)通過對東江流域水文與生態(tài)數(shù)據(jù)資料,采用小波分析和水文統(tǒng)計分析計算方法分析了東江流域的水文因子與生態(tài)因子的變化規(guī)律,應(yīng)用多元回歸分析與主成分分析方法定量分析了東江流域的水文-生態(tài)影響機制,分析計算了東江流域生態(tài)服務(wù)價值與水文因子及生態(tài)因子之間的響應(yīng)關(guān)系,推出了東江流域水文-生態(tài)影響機制與生態(tài)服務(wù)價值的響應(yīng)關(guān)系函數(shù)表達式;并對結(jié)果進行綜合分析。
[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.
