人工招引益鸟各地都有一些成功的经验。我们场地处长白山区,虽然植被面貌较我省中西部地区稍好,但由于大面积人工纯林日益增加,给森林鸟类的栖息、繁殖带来了困难:而森林害虫却日趋增多。为了控制害虫的发生,我们于1984年开始在寒葱岭、新开岭、柞木台、王牛沟林场落叶松人工林中、挂巢箱招引益鸟,收到了较好效果。1984—1985两年共挂巢箱3000个,挂巢林地面积达10,500亩。巢箱种类主要采取山雀式和椋鸟式两种,规格如表1
There are some successful experiences around the world. Although the vegetation in Changbai Mountain area of our site is slightly better than that in the central and western part of our province, the increasing availability of large-scale artificial pure forests has caused difficulties in the habitat and breeding of forest birds: the number of forest pests is on the increase. In order to control the occurrence of pests, we started to hang the nesting boxes in the larch plantations of Hanlingling, Xinkailing, Qumutai and Wangniougou in 1984 and received good results. In 1984-1985, a total of 3,000 nesting boxes were hung in the two years, with an area of 10,500 acres of hanging nests. The main types of nest box tits and starlings two species, the specifications shown in Table 1
