摘要

民國86至88年連續兩年冬季，在澎湖白沙地區以捕獲去除法進行野鼠密度調查，僅捕獲小黃腹鼠（Rattus losea）及月鼠（Mus formosanus）兩種。防治前，小黃腹鼠及月鼠比例為1.3：1，防治後，比例轉為1：4，且月鼠逐漸成為該地區之優勢鼠種。防治前野鼠棲群密度為73.7隻／公頃，經連續兩年防治，棲群密度降為2.1隻／公頃，防除率為97.2%。

Population densities of field rodents were investigated by remove trapping method at Bai-Sha, Penghu from 1997 to 1999. Only Mus formosanus and Rattus losea were found. The ratio of Mus formosanus to Rattus losea was 1:1.3 before control, and was 4：1 after control. Mus formosanus was the dominent. The average density was 73.7 per hectare before control and dropped to 2.1 after control. The control was 97.2%.
