中文摘要	为了有效应用家庭集雨水窖解决喀斯特石漠化区人畜饮水困难问题,基于泸西县19592018年降水数据,利用降雨距平百分数等方法分析该地区年际、年内降雨变化特征;通过实地调研该地区的用水、产流、贮蓄等情况,运用水量平衡原理,建立了日降雨用水平衡模型,着重探讨季风气候下不同旱涝年份降雨特征及其对水窖的影响,揭示喀斯特山区家庭饮用水窖的最佳尺寸。结果表明:(1)泸西县近60a呈暖干化趋势,年际降雨变化大,干旱年出现频率为20%;年内降雨量分布极为不均匀,雨季降雨量占84.15%。(2)按屋顶集雨面积为100m~2,每户家庭用水量0.159m~3/d,模拟得出家庭水窖的最佳尺寸为25m~3,干旱年雨水利用率可达到75.40%,家庭水窖非极端干旱年有效供水率Re≥95%,常年供水率期望值E(C)=95.19%,每口水窖至少可以提供人畜饮用水55.133m~3/a。通过设计最佳的集雨水窖,提高雨水利用率和水窖供水率,有效解决了气候变化下喀斯特石漠化区水资源日趋匮乏的瓶颈。
英文摘要	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 1959to 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 rainfallwater 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 60years,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 100m~2 and the household water consumption of 0.159m~3/d,the simulation results show that the optimal size of the household water cellar is 25m~3,the annual rainwater utilization rate can reach 75.40%;except for extremely dry years,the effective water supply rate of the family cellar is Re≥95%,the expected annual water supply rate is E(C)= 95.19%;and each cellar can provide at least 55.133m~3 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.
