1水文基本建设工程项目前期工作的特点1．1点多面广,单项工程投资相对较小水文基本建设的重点是水文站网建设。由于水文观测的需要,水文测站广泛分布在全国各大江河的干支流上,截止2005年,全国共有各类水文测站33445处(2005年水文情况年报)。每处水文测站建设工程的投资多数在100万元左右。上述特性决定了水文基本建设工程与大中型水利水电工程相比,水文基本建设工程项目前期工作具有点多面广,单项工程投资相对较小的特点。1．2单项工程的建设环境及建设内容千差万别,涉及的专业较多由于各单项工程地理分布十分广泛,根据水文测站观测任
1 Hydrology Capital Construction Project Preliminary Work Characteristics 1.1 Multi-faceted, single project investment is relatively small Hydrological infrastructure is the focus of hydrological station network construction. Due to the need of hydrological observation, hydrological stations are widely distributed in the tributaries of all major rivers in China. By 2005, there were 33445 hydrological stations in China (Annual Report on Hydrological Conditions 2005). The investment for each hydrological station construction project is about one million yuan. The above characteristics determine the hydrological capital construction projects compared with large and medium-sized water conservancy and hydropower projects, hydrological infrastructure projects in the early stage of a wide range of points, single project investment is relatively small characteristics. 1.2 Single construction environment and construction content vary widely, involving more professional Because of the geographical distribution of a single project is very wide, according to the hydrological station observation
