山区的一些水利工程一般是工程造价高,工作量大。下表是初步调查到的广东省蓄水量为5～12.4立方米。工程造价高的原因是受地形限制,一般是坝高库容小,环山开渠,渠线长,土石方工作量大;其次是运输不便,运费高。水利工程造价高,对发展 Some water conservancy projects in the mountains are generally high project costs and heavy workload. The following table is a preliminary survey of Guangdong Province, water storage capacity of 5 ~ 12.4 cubic meters. The reason for the high construction cost is due to the terrain constraints. Generally, the dam height is small, the opening of surrounding mountains and mountains, the long drainage line and the large amount of earth and rock work; followed by inconvenient transportation and high freight costs. High cost of water projects, development
