Abstract:

Illegal amphibian hunting was a quite common type of wildlife cases in recent years.In order to obtain the basic characteristics and rule of illegal hunting cases and explore the hot issues of the case,this paper conducted the statistical analysis of amphibians 1 945 cases in Jiangsu and Zhejiang Provinces.QGIS software was used to produce a hierarchical map of hot cities in JS and ZJ.Descriptive analysis of the spatio-temporal patterns of the case data was performed.The hotspot cities in JS were Nantong,Suqian,Xuzhou,Yancheng and Yangzhou,and the hotspot animals were 3 species of Pelophylax nigromaculatus,Pelophylax plancyi,Bufo gargarizans.The hotspot city in ZJ was Ningbo,and the hotspot animal was Pelophylax nigromaculatus.The hotspot animals in JS and ZJ were Anura.The number of government information released about wildlife in both provinces was positively correlated with the number of cases involved (JS r=0.467,ZJ r=0.666),and the increased supervision had controlled illegal hunting.Summer was the high incidence of cases,it was recommended that law enforcement authorities should increase the supervision on agricultural fairs and amphibian habitats in summer.For future conservation management,wildlife and wetland conservation management authorities at all levels should pay attention to the survival status of amphibians in the region.
