白马河林场云南松子测林抚育采伐设计论文

西南林学院本科毕业（设计）论文题 目：永仁县白马河林场松子测林抚育采伐设计 教学院系资源学院专业林学永仁县白马河林场松子测林抚育采伐设计（西南林学院 资源学院 650224）摘要：松是我国西南地区主要用材树种，在地区占有相当大的比重。本设计根据抚育采伐技术规程的要求，对永仁县白马河林场松子测林进行了调查。在对调查资料整理分析的基础上，采纳定量抚育采伐技术中的营养面积法确定各采伐技术要素，从而进行具体的抚育采伐设计，旨在讨论探讨营养面积法在实践中的应用，并达到白马河林场松子测林速生丰产的目的。结果表明：该子测林松由于密度大，必须立即进行抚育采伐，采伐强度为 24.6%，每隔三株应采伐一株。关键词：松；抚育采伐；营养面积法；子测林ThePinus yunnanensis of filial generation determined forest in the Bai Maheforest farm in Yongrenfor intermediate cuttingYuan Suzhen (Institute of Resources, SouthwestForestryCollege, Kunming ,Yunnan,650224)Abstract: Pinus yunnanensis is the main tree species of southwest regions in our country,and accounts fora large proportion in Yunnan. The investigation to filial generation determined forest was performed in the Bai Mahe forest farm in Yongren according to rules in technical for intermediate cutting based on the arrangement and analysis of the investigation material.The nourishment area was applied in this project which aimed at studying the practical use of nourishment area and achieving the purpose of efficient production of Pinus yunnanensis in the filial generation determined forest in Bai Mahe forest farm.The results show that the Pinus yunnanensisof filial generation determined forest need 24.6% intermediate cutting every three treesat once because of too thickness.
