【摘要】：(1)归纳生态系统服务价值的研究成果,提出河流生态系统服务功能及其相应价值的评估问题。参照类似的研究理论,界定河流生态系统功能的概念,并将河流生态系统服务功能一级分类划分为淡水供给功能、物质生产功能、生态支持功能、生态调节功能和文化娱乐功能5大类,二级分类划分为17项。依托生态服务功能的分类引入河流生态服务功能流量的概念。简述生态服务价值评估方法并概括其优缺点。(2)为有效实施水库生态价值调度,探讨水库生态价值调度的内涵,建立水库生态价值调度模型。针对新丰江水库,对其流量约束进行简要分析,在约束条件下确定典型年的调节流量,并计算典型年相应的生态服务功能流量。运用河流生态服务功能价值的评估方法进行水库生态服务价值评估。(3)以新丰江水库为案例,对新丰江水库生态服务价值进行评估,对研究区域建坝前后水库生态服务价值结果进行对比分析。生态服务价值由大至小总体排序为生态支持功能价值生态调节功能价值淡水供给功能价值文化娱乐功能价值物质生产功能价值。不同社会经济取水比例对生态价值大小的影响比较大,现阶段推荐合理的社会经济取水比例为30%。水库生态服务价值统计显示,生态支持功能价值、生态调节功能价值、淡水供给功能价值、文化娱乐功能价值、物质生产功能价值在水库生态服务价值中所占比例分别为77%、11.67%、6%、3%、2.33%。可见,生态支持功能与生态调节功能在水库服务功能中占主导地位。由此推想,可将上述比例数值作为参考权重系数,来确定水库中主导生态服务功能及主要生态服务价值。(4)归纳总结,指出论文中的不足。水库生态服务价值的评估涉及的内容范围广,需要大量的基础数据与资料,但因考虑到收集数据存在困难,在计算时取用一定数据和比例,使得研究成果与实际效益存在一定的差距,但作为评估方法参考仍是可取的。
[Abstract]:1) Inducing the research results of ecosystem service value, putting forward the evaluation of river ecosystem service function and its corresponding value, defining the concept of river ecosystem function with reference to similar research theory. The primary classification of river ecosystem service function is divided into five categories: fresh water supply function, material production function, ecological support function, ecological regulation function and cultural and recreational function. Based on the classification of ecological service function, the concept of river ecological service function flow is introduced. The evaluation method of ecological service value and its advantages and disadvantages are briefly described. This paper discusses the connotation of reservoir ecological value dispatching, establishes the reservoir ecological value dispatching model, analyzes the flow constraints of Xinfengjiang reservoir, and determines the regulating flow rate of typical year under the constraint condition. The ecological service value of Xinfengjiang reservoir is evaluated by using the method of evaluating the ecological service value of the river and taking Xinfengjiang reservoir as a case study to evaluate the ecological service value of Xinfengjiang reservoir. The results of ecological service value of reservoir before and after dam construction in the study area were compared and analyzed. The value of ecological service was ranked as ecological support value ecological regulation value fresh water supply value cultural entertainment value from large to small. The production function value of energy value material. Different social and economic water intake ratio has great influence on ecological value. At the present stage, it is recommended that the reasonable ratio of social and economic water intake is 30%. The value statistics of ecological service of reservoir show that the value of ecological support function, ecological regulation function value, fresh water supply function value, cultural and recreational function value, The proportion of the value of material production function in the ecological service value of the reservoir is 77% 11.67% and 2.33% respectively. It can be seen that ecological support function and ecological regulation function play a leading role in the reservoir service function. Therefore, it is assumed that the ecological support function and the ecological regulation function play a leading role in the reservoir service function. The above proportion value can be taken as the reference weight coefficient to determine the dominant ecological service function and the main ecological service value in the reservoir. It is pointed out that the deficiency of the paper is pointed out. The evaluation of the reservoir ecological service value involves a wide range of contents. A great deal of basic data and data are needed, but taking into account the difficulty of collecting data, some data and proportion are used in the calculation, which makes the research results differ from the actual benefit, but it is still advisable to use it as a reference for the evaluation method.
