低山丘陵区鼠类调查及相关问题探讨

１９９１～１９９２年，笔者对日照市低山丘陵区村庄周围不同生境的鼠类进行了调查。其中１９９１年以河湖岸边鼠密度最高，为７．３７％；梯田最低，为１．５４％。黑线姬鼠（Ａｐｏｄｅｍｕｓａｇｒａｒｉｕｓ）占８３．９０％，河湖岸边、干沟等生境春季捕获的均为黑线姬鼠。为防病保粮，在低山丘陵区的重点生境（河湖岸边、干沟及石堰边等）开展灭鼠活动，可取得事半功倍之效，春季尤然。

Survey on Rodents and Inquiring into Eliminating Rodents for Preventing Diseases or Grain Preservation in Hilly Country

This svrvey of rodents were carried out in different habitats around the villages of hilly country in Rizhao city in Shandong province between 1991 and 1992.The number of trap nights was 10551 in total for four quarters in 1991,the results indicated that the density of rodents was the highest in fluvio-lacustrine side and the lowerest in bench terrace area,the capture rate was7.37% and 1.54%,respectively,the capture rate was 2.01% in common ground.The A.agrarius was predominant,83.90%.All of them were A.agrarius in fluviolacustrine side,arroyo and so on in spring.Acorrding to the above,we consider that if rodents are eliminated by the methods of stressing habitats for preventing diseases or grain preservation in some areas of hilly country, getting twice the result with half the effort can be obtained. the emphasis places of eliminating rodents in the area are fluviolacustrine side,arroyo and side of stone embankment,especially in spring.
