　　摘 要：为规范水利信息化项目设计概(估)算编制，合理确定投资，针对水利信息化项目多学科、多行业交叉融合的特点，通过分析国内外相关标准规定，调研典型水利信息化项目实际情况，侧重解决概(估)算编制的重难点问题。提出符合水利信息化实际的项目划分、费用组成与单价构成，并结合软、硬件费用编制的特点，给出相关计算方法，最后通过实例应用验证相关结论。结果表明：水利信息化项目有别于常规水利工程以土木工程为主的特点，是以附加值含量高的软硬件设施设备为主体的新型基础设施项目，设计概(估)算编制应注重合理确定软硬件设备价格，根据项目实际情况科学划分并计算相关费用，才能满足项目设计概(估)算阶段投资控制的需要。

　　Abstract：In order to standardize cost estimation and reasonably estimate investment costs, based on the water resources informatization projects, this study analyzes relevant domestic and foreign standards and regulations, investigates the actual situation of typical water conservancy informatization projects, and focuses on solving the key problems of cost estimation. This study proposes the project division, cost and unit price composition in line with the actual situation of water conservancy informatization, and gives relevant calculation methods in combination with the features of software and hardware cost estimations, and verifies the conclusions through practical application. The results show that water conservancy informatization projects are different from conventional water conservancy projects which are usually characterized by civil engineering. They are a new type of infrastructure project with high added value of software and hardware facilities as the main body. Cost estimation should pay attention to the reasonable pricing of software and hardware equipment, as well as scientific categorization and calculation of related costs according to the actual situation of the project. The requirements of investment control in the project cost estimation stage can then be fulfilled.
