黄土高原残塬沟壑区隰县共有12种鼠类,农区地面夜行性鼠类群落由8种鼠类组成。近些年由于当地种植业结构调整、林果业发展、除草剂使用、退耕还林以及天敌增多等原因,农区的地面优势鼠种发生了改变。文章将1985年—2014年间4种主要害鼠在野鼠群落中数量比例的变动进行了分析研究,明确了农区地面夜行性鼠类群落的优势鼠种已由20世纪80年代和90年代的古北界鼠种子午沙鼠和大仓鼠演替成为目前的东洋界鼠种社鼠和古北界鼠种长尾仓鼠,并对优势鼠种演替的原因进行了分析,为当地的农业生产和生态建设过程中灭鼠措施和方法的调整提供了科学依据。
There are 12 species of rodents in Yuxian County in the gully region of the Loess Plateau in the Loess Plateau. The nocturnal nocturnal rodent community in the agricultural region consists of 8 species of rodents. In recent years, because of the restructuring of the local planting industry, the development of forestry and fruit industry, the use of herbicides, the return of cultivated land to forests and the increase of natural enemies, the ground superiority rodents in the farming areas have been changed. In this paper, we analyzed the quantitative changes of the four major types of rodent pests in 1985-2004 in our country. It is clear that the dominant rodents of nocturnal rodents on the ground in rural areas have been changed from the ancient ones in the 1980s and 1990s The succession of north gerbil gerbil and large hamster seedlings in Beidajie become the current squirrel in the East China Sea and the long-tail hamster in the Guibei Kingdom. The reasons for the succession of the dominant species are analyzed. Ecological construction of rodent control measures and methods to provide a scientific basis for adjustment.
