森林涵养水源的价值核算研究

Theory and Method to Accounting Value of Forest Water Conservative

森林涵养蓄水价值量核算方法较多,包括土壤蓄水估算法、水量平衡核算法、多因子回归法和用地下径流增长法计算森林涵养水源的价值。但此方法存在一个问题,需要分别求出森林涵养水源的价值,然后进行合成。在合成过程中,可能存在信息叠加等问题,使计算结果偏离实际,为此提出了森林涵养水源价值量核算模糊数学模型,V=(A○R).S,A为要素评价的权重值,R为影响森林涵养水源单要素评判矩阵所组成的综合评价矩阵,S为水资源价格向量,S=(P,P1,P2,P3,0)。

There are various methods to calculate the value of forest water conservative. Generalizing the information from all over of the world, the substitution method is applied generally. The methods discussed above are often adopted to calculate the value of forest water conservative. While these methods need to calculate the values respectively and then synthesize them. During this process, superposing of information may make a deviation from the truth. It becomes a focus that whether a model can be established to synthesize them. Here the author puts forward the fuzzy mathematics theoretical model for the value of forest water conservative. V=A○R,Where A is the weight value for factors,R is the integration value matrix which is made up of matrixes that single element, S is the vector of water source, in detail, S=(P,P1,P2,P3,0).
