Technology and Effect Analysis of Structure Optimization in Larix gmelinii Over-cutting Forest
摘要
Abstract
Taking Larix gmelinii as research object,4 structural optimization techniques,which were artificial facilitated regeneration forest,induction of mixed forest,tending of trees for intermediate cutting and regional artifi-cial tending to facilitate the regeneration forest,were proposed by the data of sample plots in the L.gmelinii forest based on the current situation of over-cutting L.gmelinii forest structure under the method of determination of thinning objects,the generation of thinning intensity,the artificial supplementary renewal measures,the cultivation and pattern of the parent tree,the regulation of forest stand succession,the forest pattern and the vertical structure optimization. And carried out a preliminary analysis of the effect.The results indicated through 4 technical measures of structure optimization,the composition of tree varieties for main storey,succession storey and regeneration storey could be effectively regulated and the forest arrangement could be optimized,the tree clustering coefficient would reduce,the space utilization ratio of forest stand would be improved and the positive succession could be facilitated consequently.关键词
