摘要：基于实地调查和资料分析，根据浙江省龙游县庙下溪小流域自然地理和社会经济状况，测算庙下溪小流域山洪灾害的区域分布和灾害影响程度，并对沿河村落防洪现状进行科学评价，分析了防洪预警方法、预警结果的合理性，进而划定受山洪威胁的沿河村落危险区，按自然村为单元确定预警指标和图值，为山洪灾害监测预警和防律提供科学依据。

Abstract : Flood disasters is a kind of natural disaster caused by continuous heavy rainfall in the mountain areas . In recent years, the frequent occurrence of mountain flood disaster in Longyou County , Zhejiang Province , not only causes devasta-ting damage to the infrastructure of the hilly area , but also poses a great threat to the people 's life and safety. Based on field survey and data analysis , the rational analysis on natural geography and social economie conditions of Miaoxia Stream water shed is conducted , and the regional distribution and disaster impact caused by mountain torrents disaster are investigated and evaluated. A scientific evaluation on flood control capacity of the villages in flood threat zone , as well as warming ap proaches , is also delineated. Taking the natural village as a unit to detemine early waming indicators and threshold , explo ring countermeasures for beaten villages in small watershed are talked about to provide technical support for flood disasters monitoring and early warning and defense .
Key words : small watershed ; flood control ; danger zone ; flood warning
衢州市位于浙江省西部，由于气候条件复杂、地形地质条件特殊，台风、强降雨引发的溪河洪水和由此诱发的滑坡、泥石流等山洪灾害发生频繁，给人民群众生命财产安全带来极大的损害，近年来，我国山洪灾害有加剧的趋势，且造成的损失也越来越大，成为我国洪涝灾害中致人伤亡的主要灾种(1-2)，山洪灾害防治已迫在眉睫

江省大力推进基层防汛防台体系和山洪灾害防治非工程措施建设，已初步建成基层防汛防灾体系3]，龙游县隶属于浙江省衢州市，属浙中丘陵盆地区,2013年被列入山洪灾害调查评价重点县，该县近些年分别于2004年、2007年、2008年和2011 年发生过较大规模的山洪灾害，对农田、房屋、学校、水利电力设施等造成极大损坏，人民群众生命财产安全受到极大威胁.本文在总结前人山洪灾害防治措施的基础上，对沿河村落防洪现状进行科学评价，划定受山洪威胁的沿润村落危险区，按自然村为单元确定预警指标和阅值，进一步增强山区防
