长白山重点国有林区森林资源动态分析--以临江林业局为例
Dynamics Analysis of the State-owned Forest Resource in Changbai Mountain---Taking Linjiang Forestry Bureau as an Example
摘要
Abstract
The dynamic changes of forest resources in Changbai Mountain were analyzed during 1977—2008 , taking Linjiang Forestry Bureau as an example. The results show :Forestry land area and forest area declined before rising trend,the utilization efficiency of forestry land increased gradually. Natural forest area was greatly reduced year by year during 1977—1997 and reduction rate was 37%,then decreased year by year. Broad-leaved accumulation of sharply reduced, coniferous forest accumulation greatly increased, and accumulation of mixed needle tends to be reasonable. Mid-maturation forest area and volume proportion are very big in 1987,and the forest area and volume of each age group tend to be reasonable in 2008 .关键词
