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 master the density and population distribution of small animals in the new tourist area of Shenzhen and provide a scientific basis for the prevention and control of small animals. Methods From March 2016 to February 2017, the small mammals in Dapeng New District of Shenzhen City were monitored by squirrel cage method to calculate the density and composition ratio of small animals. Using Excel 2007 and SPSS 17.0 software to organize and statistical analysis of data; count data between the comparison using χ2 test. Results A total of 559 small beasts were captured, accounting for 48.30% of the total catches, followed by Rattus norvegicus, accounting for 25.22%. The average density of small beasts was 7.25%, and the density of small animals was significantly decreased (1.72% ~ 11.93%). The peak density appeared in August to October. The density of small mammals in different habitats was the highest, with the highest density of 11.35% in the old estates. Conclusion The density of small mammals in the new tourist area of Shenzhen City is relatively high, and the prevention and control of small animals should be strengthened; Stinkbug, Rattus norveraceus and Rattus flavipectus are the main control targets.
