【摘要】：为更科学合理地对瓯江中上游流域水资源进行优化调控,依据流域的现状和存在的问题选取相应的优势指标和劣势指标,提出了体现依靠优势、克服劣势目标的指标体系。将层次分析法和熵权法相结合,计算指标组合权重。层次分析法确定主观权重,熵权法确定客观权重,既充分考虑了专家意见,又避免了单一赋权的片面性。并结合灰色关联度法建立灰色综合评判模型,计算得到瓯江中上游流域水资源最优调控方案,与传统指标体系和计算方法进行对比,证明提出的指标体系构建方法和综合评价模型是合理可行的。由于改进的指标体系简化了传统指标体系,突出评价的针对性,使得基于该指标体系的灰色综合评判模型可用于瓯江中上游流域水资源调控方案的评价和优选,也为其他流域水资源调控方案优选提供了新的思路。
[Abstract]:In order to optimize the water resources in the middle and upper reaches of Oujiang River more scientifically and reasonably, according to the current situation and the existing problems of the river basin, the author selects the corresponding superior index and inferior index, and puts forward the index system which embodies the goal of relying on the advantage and overcoming the inferior position. AHP and entropy method are combined to calculate the combined weight of index. The analytic hierarchy process (AHP) determines the subjective weight and the entropy weight determines the objective weight, which not only fully considers the expert opinion, but also avoids the one-sidedness of single weight. The grey comprehensive evaluation model is established by combining the grey correlation degree method, and the optimal regulation and control scheme of water resources in the middle and upper reaches of Oujiang River basin is obtained, which is compared with the traditional index system and calculation method. It is proved that the method of constructing the index system and the comprehensive evaluation model are reasonable and feasible. Because the improved index system simplifies the traditional index system and emphasizes the pertinence of the evaluation, the grey comprehensive evaluation model based on the index system can be used to evaluate and select the water resources regulation scheme in the middle and upper reaches of Oujiang River. It also provides a new idea for the optimal selection of water resources control schemes in other watersheds.
