研究结果表明:西北各省区地下害鼠主要监测对象是甘肃鼢鼠、中华鼢鼠和高原鼢鼠;监测的主要地面害鼠是小家鼠、达乌尔黄鼠和灰仓鼠等13种。草兔已经成为一种危害农林牧业生产的主要灾害。害鼠发生面积不断扩大,且有爆发成灾的趋势。退耕还林工程的实施,使原先发生在农田的害鼠变成了林地害鼠,造成了在局部地区林地鼠害发生面积的急剧增加。
The results showed that the main monitoring objects of ground pest rats in Northwest China were Gansu zokor, Chinese zokor and plateau zokor; the main ground pests monitored were 13 species of Mus musculus, Daurian ground caterpillar and gray hamster. Rabbit has become a major disaster that endangers the production of agriculture, forestry and animal husbandry. Rodent occurred area continues to expand, and there is a trend of disaster outbreak. The implementation of the Project of Conversion of Cropland to Forestland made the pest rats originally occurred in the farmlands become forest pests, causing a sharp increase in the area of rodent pests occurring in some areas.
