非法狩猎两栖动物是近年来比较常见的野生动物案件类型。为获得非法狩猎案的基础特征和规律,探讨案件的热点问题,对江浙两省1 945例两栖动物案件信息进行统计分析。利用QGIS软件分析江浙两省的热点城市,对案件数据进行时空规律的描述性分析。江苏省的涉案热点城市为南通、宿迁、徐州、盐城、扬州,热点动物为黑斑侧褶蛙(Pelophylax nigromaculatus)、金线侧褶蛙(Pelophylax plancyi)、中华蟾蜍(Bufo gargarizans)3种;浙江省的热点城市为宁波,热点动物为黑斑侧褶蛙。2011—2020年江浙两省发布的有关野生动物的政务信息数量与涉案次数均呈正相关(江苏r=0.467,浙江r=0.666),监管力度的强度对非法狩猎有调控作用。夏季为案件的高发期,建议执法部门应在夏季加大农贸集市、两栖动物栖息地的监管力度。在今后的保护管理中,各级野生动物和湿地保护管理部门应关注区内两栖动物的生存现状。

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.
