汉江流域水权初始配置模型研究

INITIAL ALLOCATION FOR MODEL OF WATER RIGHTS IN HANJIANG RIVER BASIN

水权管理的关键和难点是水权的初始分配。做好初始水权的分配,能够促进水资源的优化配置,达到以水资源的可持续利用支持国民经济和社会的可持续发展。根据水权初始分配有效性、公平性、可持续性发展的原则,分析了水权初始分配的主要影响因素,主要是经济发展、用水效益、平均分水、现状用水、水源地优先、生态环境以及社会发展;构建了水权初始分配的层次结构图;采用多目标半结构性模糊优选模型研究流域水权初始分配,该模型根据人的经验知识量化原理确定定性指标的相对优属度和各指标的目标权重,为确保模型的实用性,目标值重要性比较时采取了专家咨询手段;定量指标则根据实际情况采用越大越优型的相对优属度公式或越小越优型相对优属度公式。

Initial allocation of water rights is the key point for water management. The optimization of water resource allocation will promote sustainable development of national economy and society. In consideration of efficiency, impartiality and sustainability, affective factors for the initial allocation of water rights were discussed in this paper, including economic development, efficiency of water usage, average water distribution, current water consumption, water resource field preference, ecological environment and social development. In this paper, an index system was founded, and semi-structural and multi-objective fuzzy optimal selection model was adopted; the objective weight and relative membership degree of qualitative objectives were calculated depending on practical quantified knowledge. Expert consultation was used to compare the importance of two objectives to ensure the practicability of the model. The relative membership degree of quantitative objectives was calculated by computing formula according to practical situation. By applying the model into Hanjiang river basin, the initial allocation of water rights was performed.
