Abstract
As of 2022,there are 398 small reservoirs in Xinjiang,with a total storage capacity of 1.107 billion m3,including 149 mountain reservoirs and 249 plain reservoirs.Although these small reservoirs account for 68.9％of all reservoirs in the region,their storage capacity represents only 5.1％,indicating very limited regulation and storage capabilities.Nearly one-quarter of these reservoirs have exceeded their service life.Additionally,design flaws from the 1950s and 1960s,poor management,and insufficient funding have led to issues such as disrepair,low flood control standards,weak seismic resistance,and severe evaporation and leakage.This study thoroughly examines the root causes of these problems and proposes new solutions,including risk elimination and reinforcement measures,replacing plain reservoirs with mountain reservoirs,and the"overtopping without failure"theory,providing references for the future governance of small reservoirs.关键词
