基于可拓评价的农村饮用水工程运行管理模式研究

A Study on the Mode of Operation and Management of Rural Drinking Water Projects Based on Extension Evaluation

针对农村饮用水工程运行管理模式的多样化和复杂化,选择一种新型的动态可拓评价模型,以浙江省为例选择典型的3种运行管理模式,即村集体管理模式、承包管理模式和用水户协会管理模式进行比较评价,旨在通过评价找出它们的适应条件及优劣,以便在全省范围内推广应用。评价过程中创新性地将可拓评价模型和离差分析法相结合,建立了可拓评价的物元模型、过程元模型和事元模型,通过确定衡量条件、离差分析法确定权系数、建立关联函数与计算合格度、计算规范合格度、计算优度等一系列步骤,选取了浙江省丽水市莲都区15个不同运行管理模式的农村饮用水工程进行评价,得出评价结果。评价结果与实际基本一致,验证了模型和方法的可行性,这为下一步模型的推广应用及信息化提供了基础,同时也为决策部门开展农村饮用水工程运行管理的模式应用提供了技术支撑。

Since operation and management mode for rural drinking water engineering projects are diverse and complicated, it is necessary to select a new dynamic extension evaluation model by taking Zhejiang Province as an example. Three typical operation and management modes are cho sen, for comparative evaluation, including village collective management mode, contract manage ment mode and water user association management mode. The evaluation aims to identify their suitable conditions, advantages and disadvantages for convenient extension and application. In the evaluation process, the extension evaluation model was innovatively combined with deviation anal ysis method and matterelement model, process element model and material element model for ex tension evaluation are established, and through a series of steps such as to determine measured conditions, determine weight coefficient via deviation analysis method, and established associated function and calculation qualified degrees, and calculation specification qualified degrees, and calculation excellent degrees. Fifteen different run management modes of rural drinking water en gineering projects in Liandu District of Lishui city in Zhejiang Province were selected for evalua tion, and evaluation results were obtained. The evaluation results are basically consistent with the actual conditions, verifying the viability of the model and method. This provides basis for the model application and informationization, but also provides technical support for the operation and management of rural drinking water project decisionmaking sector mode application in the future.
