摘要
对开平市大沙河灌区农业综合开发节水工程项目水资源进行水量平衡供需计算分析,计算结果分析表明,灌区节水工程项目实施改造和调整农业结构后,除可满足城镇供水要求及农业灌溉保证率达到90%外,还有盈余水量,达到节水增效的目的,项目综合效益显著。
We have already carried out the assessment and analysis on water resource and supply and demand balance for the water saving project in Dashahe irrigated area,which indicate that after reconstructing the water saving project in Dashahe irrigated area and adjusting the agricultural structure,the project can fulfill beside the demand of urban water supply as well as 90% of guarantee rate in irrigation,there is a surplus of water,it can achieve the purposes of water saving efficiency and the overall project efficiency is significant.
