摘要
应用地理信息系统空间分析技术,对凉水自然保护区1974年和2009年2个年度的森林资源主要因子进行了时间和空间上的动态分析。结果表明,35年来,保护区内森林结构正在向着良好的方向发展,到2009年,天然红松林逐渐占据主导地位,成过熟林继续保持主导地位,天然林比例大幅提高,森林蓄积量降低。35年来,保护区内的森林资源受到了很好的经营,正向着森林的顶级群落演变。
The main factors of the forest resources of Liangshui Nature Reserve in 1974 2009 were analyzed by using GIS spatial analysis techniques from the time space aspects.Result shows that the forest structure in the reserve developed toward a good direction during the 35 years' protection.By 2009,natural Pinus koraiensis gradually occupy the dominant position and mature forests continue to maintain a dominant position;the proportion of natural forests increase and forest volume decrease.The forest resources,which have been protected well over the past 35 years,are developing toward the forest climax community.
