摘　　要：南岭保护区粉蝶共35个种,隶属于16个属,资源十分丰富。南岭保护区粉蝶和海南粉蝶相似百分率高达72%,二者之间有着共同起源的密切关系。2008年1-2月的雨雪冰冻灾害发生后,再次对南岭保护区粉蝶进行调查,发现南岭保护区粉蝶的种类明显减少,有20个种的粉蝶没有被发现,占南岭保护区粉蝶总数的57.14%。可见,雨雪冰冻灾害对南岭保护区的粉蝶多样性产生了破坏性的影响。Totally 35 species of Pieridae,belonged to 16 genera,had been found in Nanling National Nature Reserve in a previous multiple-years investigation.The Pieridae fauna were 72 % similar to that in Hainan Province,and these butterflies in the two places had the same origin.An investigation was carried out again after a snow disaster which happened during the period of January to February 2008.The result showed that populations and species of Pieridae decreased obviously.Up to 20 species of Pieridae,accounted for 57.14% of total Pieridae in Nanling,were not found.It indicated that the snow disaster brought a destructive impact on the Pieridae biodiversity in Nanling National Nature Reserve.
