云南省森林资源动态变化分析与评价

摘要

以1978-2012年开展的7次森林资源监测数据为依据,分析云南省35年来森林资源的数量及质量动态变化特点.结果表明,全省森林面积快速增加,林分质量有所下降;森林蓄积持续增长,长消比例逐年提高;人工林分持续增加,经济林发展速度快;竹林面积总体减少,天然竹呈下降趋势.在对主要森林资源变化趋势进行分析评价的基础上,提出相应对策.%Based on the monitoring data of forest resources from 1978 to 2012,this paper analyzed the dynamic change characteristics of forest resource in quantity and quality for 35 years.The results showed that the forest area was rapidly increasing,but forest quality was decreasing;the accumulation of forest continued to grow,long extinction ratio was increasing year by year;artificial forest was continuously increasing,economic forest developed rapidly;the area of natural bamboo was reducing,and the total area of bamboo area declined.Therefore,on the basis of the analysis and evaluation of forest resources,the paper put forward the corresponding countermeasures.
