摘  要：
针对近年来小金县油松枯死现象有进一步蔓延的趋势,本研究通过分析油松立地条件、病虫害发生情况对其健康的影响,结果表明病虫害及立地条件的综合作用是导致小金县油松枯死的主要因素。由于小金县油松立地条件较差,长势弱,给油松赤枯病、松针锈病、小蠹、天牛等病虫害提供了侵入的机会,导致当地油松树势衰退,甚至死亡。因此,应加强林分抚育,监测重点病虫害的发生。

摘  要：
In recent years,a lot of trees of Pinus tabulaeformis forest have been found to be withered or dead in several regions in Xiaojin county and this phenomenon has a further spreading tendency.In this paper,analysis is made of pests and site conditions of P.tabulaeformis.The results have shown that the withered reason of P.tabulaeformis in Xiaojin is the result of the comprehensive function of pests and site conditions.Because of poor site conditions in Xiaojin,P.tabulaeformis growth is worse than other tree species,thus giving the opportunity for the invasion of pests,such as blight,pine needle rust,bark beetles and longicorn beetles,and causing the growth of P.tabulaeformuis to decline and even die.Therefore the effective measures should be adopted to control these potential disasters and strengthen the tending of the stand and the monitoring of pests.
