摘  要:
本文从发病林分、立地条件、病虫害、气象因子等方面对无为市国外松衰退现象进行详细调查,在此基础上分析得出:林分早期衰亡是一种林木衰退病,是由土壤、林分密度、森林病虫害、干旱、霜冻等因素诱发林木衰退,并不断激化促进林木衰退所致;改良土壤、加强抚育管理和控制病虫害危害,对衰退病的防治具有一定效果。

摘  要:
In this paper, a detailed survey was made on the degradation actualities of introduced foreign pine plantations in Wuwei City from such aspects as diseased stands, site conditions, diseases and pests and meteorological factors. An analysis based on the survey showed that the early decline of the stands was the forest degradation caused by multiple factors including soil, stand density, forest diseases and pests, drought and frost. Improving soil, strengthening tending management and controlling diseases and pests could have some effects on controlling the degradation.
