云南松是我省的主要用材树种。云南松蓄积占全省有林地总蓄积的44.1％,面积占全省有林地面积的64.6％。它分布在海拔1500—2800公尺山地,除我省外还有贵州,四川两省也有分布。过去对云南松林分平均高与蓄积的相关关系的研究较多,而对云南松林分中最大高与蓄积的相关关系研究较少。云南松作为我省的重要用材树种,无论在科研和生产实践中,对最
Yunnan pine is the main timber species in our province. Pinus yunnanensis accounts for 44.1% of the total forest reserves in the province, accounting for 64.6% of the total forest area in the province. It is located at 1500-2800 meters above sea level in the mountains, in addition to my province there are Guizhou, Sichuan Provinces are also distributed. In the past, there was a great deal of research on the relationship between the average height and the accumulation of Pinus yunnanensis in Yunnan Province. However, the correlation between the maximum height and the accumulation of Pinus yunnanensis was few. Yunnan pine as an important timber species in our province, both in research and production practices, the most
