地下水库综合效益评价研究

地下水库综合效益评价对地下水库的规划、建设和管理具有重要的科学意义和应用价值。为研究地下水库在修建和运行过程中对水资源、生态环境、社会经济的影响，在对地下水库综合效益内涵探讨的基础上，从整体角度构建地下水库综合效益评价指标体系，以拟修建的陕西省石川河富平地下水库为例，选取适宜的指标，采用实数编码的加速遗传算法优化投影寻踪分类模型，对基准年2018年和规划年2030年石川河富平地下水库综合效益进行评价。结果表明：石川河富平地下水库效益良好，地下水库修建后运行至2030年时，具有较好的生态维护价值和水资源恢复效果，间接论证了修建该地下水库的必要性，为其后续规划设计和管理运行提供了重要的决策支持。该评价指标体系切实可行，可广泛应用于地下水库综合效益评价。

Comprehensive benefit evaluation of a groundwater reservoir

Comprehensive benefit evaluation is crucial to the planning, construction and management of groundwater reservoirs. In order to study the influence of the construction and operation of groundwater reservoirs on local water resources, ecological environment and social economy, an evaluation index system of groundwater reservoir comprehensive benefit is constructed from the overall perspective based on the discussion of the connotation of groundwater reservoir comprehensive benefit. Taking the proposed Fuping Groundwater Reservoir of Shichuan River in Shaanxi Province as an example, appropriate indexes are selected and the real-coded accelerated genetic algorithm is used to optimize the projection pursuit classification model. The comprehensive benefits of Fuping Groundwater Reservoir in Shichuan River are evaluated taking 2018 as the base year and 2030 as the planning year. The results show that the benefit of Fuping Groundwater Reservoir in Shichuan River is satisfactory, it still has good ecological maintenance value and water resource remediation effect in 2030, which indirectly demonstrates the feasibility of the construction of the proposed groundwater reservoir and provides important decision support for its subsequent planning, management and operation. The evaluation index system is feasible and can be widely used in comprehensive benefit evaluation of groundwater reservoirs.
