历年来春季灭黄鼠前黄鼠密度调查均采用一日钢闸法,需用大量的钢闸,较多的人力和充足的时间,影响大范围的黄鼠密度调查。我们用1983年4月和1984年4月吉林省11个县(市)黄鼠密度调查数据为样本,建立了4个直线回归方程,并配置了68％可信范围,以此推算春季灭黄鼠前黄鼠密度及样方分布。
In the past years, the density of ground squirrels in front of the ground squirrel has been surveyed using the steel gate method in the spring. A large number of steel gates, more manpower and sufficient time are needed to influence the density survey of a wide range of ground squirrels. In April 1983 and April 1984 in Jilin Province, 11 counties (cities) rat density survey data as a sample, the establishment of four linear regression equation, and the allocation of 68% confidence range, in order to calculate the spring yellow Density and quadrats distribution in front of rat.
