Dynamic Analysis and Management Countermeasure of Forest Resource Structure in Linjiang Forestry Bureau
摘要
Abstract
The forest structures like land types, origin of stands, dominant species and stands age as well as forest stock volume and productivity in recent 20 years of Linjiang forestry bureau, Jilin province were dynamically analyzed based on annual review data of 1000 plots and 5 forest maps of 1977, 1982, 1987, 1992 and 1996. The problems existed in the forest resources wen summarized and the corresponding strategies were put forward. Results show that, besides the land area is not obviously changed, there are still many problems such as the proportion of rare species is relatively small. and the volume percentage of dominant species gradually decreases. The proportion of young forest and mature forest is gradually increasing, and middle- age forest first increases and then decreases with slightly changed as a whole. The mature and overmature forest is little, and so is recoverable forest resource. The area of nature forest with different stands decreases greatly, and the update speed of plantation can not keep up with that of harvesting. Therefore, it is recommended to adopt cutting-and-culturing forest management mode and relevant measures to adjust the forest resource structure.关键词
