A number of aircraft precipitation enhancement bases have been built in Shanxi Province, which can carry out precipitation enhancement operations throughout the year and respond to emergencies, and carry out artificial precipitation enhancement and snow enhancement operations many times. Focusing on the needs of increasing soil moisture, increasing reservoir water storage capacity, purifying air quality, reducing forest fire risk and protecting soil erosion, Shanxi Province has continuously improved the business layout of artificial precipitation (snow) enhancement with ecological restoration as the mainstay.

Water resources in Shanxi Province;
1. The main source of water resources in Shanxi Province is local precipitation. From 1956 to 2000, the average precipitation in the whole province was 79.5 billion m, equivalent to the rain depth of 508.8 mm. During 65438-0980-2000, the average precipitation in the whole province was 75.5 billion m, equivalent to the rain depth of 483.2 mm. Compared with 1956- 1979 series precipitation, the precipitation in this period decreased by 9.04%. Since 1970s, precipitation in most areas of Shanxi Province has been relatively dry.
2. Due to the constant changes of underlying surface conditions caused by human activities, the surface water resources in most areas of Shanxi Province are gradually decreasing. The annual average of river runoff in 1980-2000 in Shanxi Province is 7.289 billion m, which is lower than the series average of 13.9 16.0% 1956-2000. Compared with the average value of 1956~ 1979 series, it is reduced by 4 1.5 1 100 million m, with a reduction rate of 36.35%.
