1995～ 1998年在祁连山北坡人工造林地对中华鼢鼠进行实地调查 ,研究不同生境中鼢鼠的数量分布和发生危害情况 ,基本掌握了其种群数量变动及危害规律 ,并根据气温、性比等因素 ,建立了祁连山林区中华鼢鼠短、中期数量测报模型 :F =1 6 79p。
After the field investigation on Myospalax fontanieri in the plantations on the north slope of Qilian Mountains from 1995 to 1998,damage and population distribution of Myospalax fontanieri in different habitats were studied and the regularity of population variation and damage were found out and its short and medium term population prognosis model(F=1 679p)was established according to the temperature,sex ratio and so on.
