落叶松人工林的调控要素有间伐对象、间伐时间、间伐强度和间伐方式等。间伐方式应根据林分的特点和培育的目的来确定,必须从落叶松的生物学特性出发,确定一个科学的间伐强度。在进行落叶松人工林抚育间伐时,间伐对象的选择相当重要。提高林分生长量的关键在于:根据落叶松的生物学特点和不同生长发育阶段,采取合理的抚育措施,科学地调控林分生态因子。对落叶松近熟林也可以高强度间伐,然后采取林下更新的经营方式,既促进了林木的径级增长,又充分地利用了生态位空间,提高了林地利用率。
Larch plantation control elements are thinning object, thinning time, thinning intensity and thinning methods. Thinning methods should be based on the characteristics of the stands and the purpose of cultivation to determine, we must start from the biological characteristics of larch, to determine a scientific thinning intensity. In the larch plantation tending thinning, the choice of thinning object is very important. The key to improve the stand growth is to adopt reasonable tending measures according to the biological characteristics of larch and different stages of growth and development to scientifically control the stand ecological factors. The larch near-mature forest can also be high-intensity thinning, and then take under the forest management mode of operation, not only to promote the diameter growth of trees, but also make full use of the niche space and improve the utilization rate of forestland.
