| 摘 要： | 以东北林业大学帽儿山实验林场为调查对象,以1983年和2004年森林经理调查林相图和森林经理调查小班数据为基础,以地理信息系统技术为支持,将两期(1983年和2004年)的矢量数据专题图叠置,生成两期森林资源变化图,包括林场区域、林班区域、龄组变化、树种起源变化分布图.进而直观、鲜明地反映出研究区域两个时期间森林类型空间分布上的变化特征,既能反映出前期的森林资源状况,又能显示森林资源现状,为可持续经营森林资源提供科学依据.

| Abstract: | Based on the forest management inventory stand maps and subcompartment data in 1983 and 2004 of Maoershan Experimental Forest Farm of Northeast Forestry University,supported by GIS techniques,the vector forest maps of 1983 and 2004 were overlaid to generate a changing map of forest resources,including distribution maps of forest farm boundary,compartment boundary,age class and species origin.The changes of forest types in space distribution of 1983 and 2004 were reflected in the map. It not only reflects the forest resource in the past,but also at present.It can offer the scientific data for the sustainable management of forest resources. |
