摘要/Abstract

摘要： 基于遥感技术，并在GIS的支持下对长白山林区露水河林业局森林资源变化进行研究。结果表明：1985年研究区森林资源本底为成熟阔叶林和成熟针叶林，二者联合比例为68.52%；1999年为中龄针叶林和成熟阔叶林，二者联合比例为65.96%。15年间森林面积增加了17.6%，成熟林比例下降到4875%；在人为因素和自然因素的共同影响下，研究区森林资源发生了显著变化，其中有些森林经营方式不够合理，不利于森林进展演替；森林蓄积结构较为单一，应改进营林措施，增加乡土良种的培育.

Abstract: By using remote sensing and GIS, this paper studied the temporal changes of forest resources in Lushuihe Forest Bureau of Changbai Mountains. The results showed that in 1985, mature broadleaved and coniferous forests occupied 68.52% of the forest resources, but in 1999, medium-age broadleaved and coniferous forests occupied 65.96%. During the fifteen years, forest area increased by 17.6%, and the proportion of mature forests decreased from 68.52% to 48.72%. The forest resources in the study area changed greatly under the effects of human activities and natural factors. Some forest management measures adopted were not rational, and harmful to the progressive succession of forests. The volume structure of the forests was relatively single, and some forest management measures should be modified, with the cultivation of more local forest species to be strengthened.
