Abstract:: In order to effectively use rainwater in the family water cellar to solve the drinking water difficulties of people and animals in karst rocky desertification areas, based on the precipitation data of Luxi County from 1959 to 2018, the characteristics of rainfall variation in this area were analyzed by means of percentage of rainfall anomaly, and through in situ investigation in the area with water use, runoff production and storage in this area, etc. Based on the principle of water balance, a daily rainfall—water balance model was established, and the characteristics of rainfall in different drought and flood years under monsoon climate and its influence on water cellars were emphatically discussed, so as to reveal the optimal size of family drinking water cellars in karst mountainous areas. The results show that:(1)in the past 60 years, Luxi County showed a trend of warming and drying, with great inter-annual rainfall variation, and the occurrence frequency of drought years was 20%; the annual rainfall distribution was extremely uneven, with the rainy season accounting for 84.15%;(2)according to the roof rainwater harvesting area of 100 m² and the household water consumption of 0.159 m³/d, the simulation results show that the optimal size of the household water cellar is 25 m³, the annual rainwater utilization rate can reach 75.40%; except for extremely dry years, the effective water supply rate of the family cellar is R_e≥95%, the expected annual water supply rate is E(C)=95.19%; and each cellar can provide at least 55.133 m³ of drinking water for human and livestock in a year. Through the design of the best household rainwater harvesting cellar, the utilization rate of rainwater and the water supply rate of the cellar are both improved, and the bottleneck of water resource shortage in the karst rocky desertification area under climate change is effectively solved.
