深圳市新型旅游区小兽密度和种群分布状况研究

Research on the density and population distribution of small mammals in the new tourist area of Shenzhen city

目的掌握深圳市新型旅游区小兽密度和种群分布状况,为小兽防制提供科学依据。方法于2016年3月至2017年2月,用鼠笼法对深圳市大鹏新区小兽进行监测,计算小兽密度和构成比。采用Excel 2007和SPSS 17.0软件对数据进行整理和统计分析;计数资料率间的比较采用χ2检验。结果共捕获小兽559只,以臭鼩鼱为优势种,占捕获总数的48.30%,其次为褐家鼠,占25.22%;小兽平均密度为7.25%,小兽密度季节消长明显(1.72%~11.93%),密度高峰期出现在8-10月;不同生境小兽密度不同,以旧屋村最高,密度达11.35%。结论深圳市新型旅游区小兽密度较高,应加强小兽防制工作;臭鼩鼱、褐家鼠和黄胸鼠为主要防制对象。

Objective To investigate the density and population distribution of small mammals and provide the scientific basis for the small mammal control in the new tourist area of Shenzhen city.Methods The cage trapping method was used to monitor small mammals in Dapeng district from March 2016 to February 2017.The small mammal density and composition ratio were calculated,and the enumeration data were analyzed by chi-square test.Results A total of 559 small mammals were caught,with Suncus murinus being the predominant species accounting for 48.30%,followed by Rattus norvegicus accounting for 25.22%.The average density of small mammals was 7.25%,and the seasonal fluctuation was obvious（1.72%-11.93%）,with the peak period from August to October.The small mammal density varied with different habitats,the highest density（11.35%）was in the old houses.Conclusion The small mammal density in the new tourist area was relatively high.So,it should be strengthened to prevent and control the small mammals.Suncus murinus,R.norvegicus,and R.tanezumi are the main vectors of concern.
