Study on wetland restoration technology by artificial precipitation enhancement

The most critical factor for wetland restoration is the surface water and the artificial precipitation enhancement is one of direct ways to gain water resources at present. Based on the experimentation data and experiences in Yushu of Qinghai Province, the technical feasibility of artificial precipitation enhancement for the wetland restoration was analyzed. The results indicated that the effect of artificial precipitation enhancement on rainfall, wetland biomass and the soil moisture was significant. The precipitation, forage yield and soil moisture within 0 to 10 cm were increased by 10.73% (or 33.8 mm), 9.02% (or 10 g/m2) and 39% respectively.
