河套灌区节水改造工程是以节水为中心的续建配套和技术改造。节水工程的实施,使河套灌区的引黄水量将由52亿m3逐渐压缩到40亿m3,灌区用水状况发生重大改变的同时地下水的补给与埋深,土壤盐渍化、灌区的生态系统都发生一系列变化。因此合理实施节水改造工程,加强灌区生态环境建设,是实现地区经济可持续发展的重要保障。 Hetao irrigation water-saving project is to improve water conservation as the center continued construction and technological transformation. The implementation of water-saving projects will enable the water diversion from the Hetao Irrigation District to be gradually reduced from 5.2 billion m3 to 4 billion m3. While the water use conditions in the irrigation districts have undergone significant changes, the recharge and burial depth of groundwater, soil salinization and the ecosystem of irrigated areas will all occur A series of changes. Therefore, it is an important guarantee to realize the sustainable development of the regional economy by reasonably implementing the water-saving renovation project and strengthening the ecological environment construction in the irrigated area.
