内蒙古西部处于腾格里大沙漠、乌兰布和沙漠的荒漠干旱地区。该地区的城市及农田供水条件是十分困难的。不过,在山前冲积扇地区深层地下水比较丰富,城乡供水一般依靠打机井取水。但是井深达200米以上,机井的投资较大,如果布点较密则机井出水量会彼此干挠,如布点较稀则满足不了城乡供水需要,所以一般的仍需要考虑截留地表水解决用水需要。在内蒙古西部地区的干旱山区,工厂矿山的布点较多,集中了大量的
The western part of Inner Mongolia is located in arid and arid regions of the Tengger Desert, Ulan Buh Desert. The urban and farmland water supply conditions in the area are very difficult. However, there are abundant deep groundwater in alluvial fan areas in the piedmont. Water supply in urban and rural areas generally depends on pumped well for water intake. However, wells with a depth of 200 meters or more have a large investment in drilling wells. If the distribution points are relatively dense, the water output from the wells will be indifferent to each other. If the water supply points are too thin, the water supply needs of urban and rural areas will not be met. Therefore, the need to retain surface water to solve water needs to be considered. In the arid mountainous area in the western part of Inner Mongolia, there are more factories and mines, concentrating a lot of
