计划火烧在四川云南松林区得到及时推广应用,大大提高了控制森林火灾的能力,起到了明显的防火作用,有效地防止了森林火灾的发生。计划火烧作为保护森林的措施和手段,已被各地所接受。然而,计划火烧后的生态效果究竟如何?会不会影响林木生长,以及社会经济效益怎样?都是人们极为关心的问题。为此,我们于1991年1月对1988年和1989年试验火烧后的生态效果进行了调查研究。通过林木生长量、幼树死亡率、草本灌木恢复情况调查,探讨计划火烧对林木生长的影响,综合分析火烧后的生态效果。一、研究方法在火烧试验林地,采用标准地调查方法,
Planned fire was timely popularized and applied in Songlin District, Yunnan Province, greatly improving the ability to control forest fires, playing a significant role in fire prevention and effectively preventing the occurrence of forest fires. Planned fire as a measure and means to protect the forest has been accepted by all localities. However, what is the ecological effect after the project is planted? Will it affect the growth of trees and the socio-economic benefits? All are matters of great concern to people. To this end, we conducted a survey in January 1991 on the ecological effects of the tests after burning in 1988 and 1989. Based on the investigation of the growth of tree growth, the mortality of saplings and the recovery of herbaceous shrubs, the effects of planned fire on the growth of forest trees were discussed, and the ecological effects after fire were comprehensively analyzed. First, the research methods In the fire test forest, using a standard survey method,
