基于选择模型的灌区信息化水平评价指标研究

A Study on Evaluation Indicators of Informatization Level of Irrigation District Based on Selection Model

针对当前我国灌区信息化发展水平评价中指标选取存在的随意性、重复性和不完整的问题,在分析我国灌区信息化建设发展现状和评价指标选取原则的基础上,以指标简洁性和完整性为目标,根据前人提出的评价方法和模型,进行灌区信息化水平评价指标选取和优化研究,从信息基础设施建设、应用性能、效益效果三个方面构建了一套灌区信息化水平评价指标体系。以湖北漳河灌区的信息化系统建设情况为例,运用评价指标优化选择模型,将灌区信息化水平评价指标由40个优化减少到17个,指标的完整性达到85.13,满足了指标数量少且完整性高的目标。

Aiming at the problems of randomness,repeatability and incompleteness in the indicators selection of the informatization development level evaluation of irrigation ditricts in China,on the basis of analyzing the informatization development status in irrigation districts and the selection principle of evaluation indexes,according to the evaluation methods and models put forward by predecessors,the evaluation indicators selection and optimization of informatization level of irrigation districts were studied with the goal of index simplicity and integrity,and a set of evaluation index system for informatization level of irrigation districts was constructed from three aspects,including information infrastructure construction,application performance and benefit effect.Taking Hubei Zhanghe Irrigation District as an example for empirical study,the indicators optimization selection model was used.The result showed that the indicators could be optimized from 40 to 17 and the completeness of indicators system could reached as high as 85.13%,which met the goal of fewer indexes and higher integrity.
