摘要: 随着杉木人工林面积的不断扩大,杉木人工林地力衰退问题日益严重,而炼山是导致杉木人工林地力衰退的主要原因之一。本文在国家“七五”攻关子课题《炼山对杉木幼林生态系统影响机理及计量评价研究》连续10a定位研究成果的基础上,对国内外有关炼山对采伐剩余物、水土流失、土壤肥力、杉木生长影响等问题进行全面阐述,同时对炼山利弊问题进行归纳与总结,并提出相应对策,这对变革传统杉木经营制度、可持续利用南方山地资源具有重大指导意义。

Abstract: ith the area of Chinese fir plantation increasing constantly, the soil fertility degradation of the site of Chinese fir plantation is increasingly serious. Controlled burning is one of the major causes which cause the soil fertility degradation of the site of Chinese fir plantation. On the basis of the achievements of previous related studies, we, in this paper, fully expound the effects of controlled burning on the slashes, soil and water loss, soil fertility and Chinese fir growth at home and abroad, summarize the advantages and disadvantages of controlled burning,and raise some corresponding countermeasures. This is of great significance for changing the traditional culture system of Chinese fir and for the sustainable use of the resources of the mountainous area in South China.

Key words: ontrolled burning, Chinese fir plantation, ecological system, advantages and disadvantages, countermeasure
