建国以来,我省营造了大量人工刺槐林,现已大多郁闭成林,急待抚育间伐,调节林分密度,改善林木生长条件,以便尽快成材和发挥森林的有益效能。我省的抚育间伐,以往一般应用定性间伐,近年来才试验、推广定量间伐。为了进一步探索定量间伐的理论,改进编表方法,使编出的经营密度管理表,更加符合我省的实际情况,更有实际应用价值,今年我院结合吉县的林业区划工作,试编了人工刺槐林的经营密度管理表。 Since the founding of the People’s Republic of China, a large number of Artificial Robinia pseudoacacia forests have been established in our province. Most of them are now closed to afforestation. There is an urgent need of tending thinning, adjusting stand density, and improving the conditions for tree growth so that they can be used as soon as possible and the beneficial effects of forests can be realized. In our province, tending and thinning, in the past the general application of qualitative thinning, in recent years before testing to promote quantitative thinning. In order to further explore the theory of quantitative thinning, improve the tabulation method, make the compiled management density management table, more in line with the actual situation in our province, more practical application value, this year combined with Jixian County Forestry Division of our work, Man-made acacia plantation management density management table.
