The characteristics of bases are:1) pure larch stands over 133 ha mu;2) the age of the stands over 15 years cannopy density over 0.7;3) low mountain, middle-upper part hills, shady sides.The available control methods are: thinning, changing the habitat of the stands, introducing some spiders artificially to kill the adults of Dendrolimus superans Butler,applying mixed forest. These measures can prevent the stands from becoming outbreak bases.

落叶松毛虫(Dendrolimuslstperans Butler)周期性大发生,与大发生基地(虫源)林分某些条件有密切关系。这些条件是:①13.3ha以上大面积落叶松纯林;②林龄在15年以上,郁闭度大于0.7;③低山、丘陵中上部,漫岗顶部。 在松毛虫大发生增殖期,大发生基地面积仅占全林面积的7.1%,便于重点控制。所采取的措施是:进行间伐抚育,改善基地林分生境;人工助迁蜘蛛;采用化学防治,把松毛虫虫口控制到最低水平线上;搞好封山育林、混交造林,预防松毛虫大发生基地的形成。

This paper is based on the informations gained from the Ⅸ World Forestry Congress aswell as from some newest periodic literatures. It explains the new trends in the worldplantation forestry.The main contents include the scale of afforestation and direction of itsdevelopment,the choice of species,establishment of mixture stands, quality of seeds andplanting stock, silvicultural techniques and their rational combinations, etc.
