摘　　要：由于人为活动或自然因素干扰,荒山作为我国一种典型的退化生态系统正在不断增加。在东部基础地质环境遥感调查中发现,长三角经济区存在着许多荒山,主要分布在浙江省大部及江苏省北部及西南部。根据地貌资料统计,浙江省低山丘陵为4.38万km2,根据野外森林利用情况的调查分析,浙江省至少有1/3即1.46万km2低山丘陵植被遭到严重破坏,后期无人管理,处于自然恢复状态。若要进行经济林建设,既可使生态环境得到恢复,又可以取得巨大的经济效益。Due to human activities and natural disturbance, the barren hills as a typical degradation ecosystem are constantly increasing. On the basis of geological environment remote sensing survey in eastern China, the authors have found that in the Yangtze River Delta Economic District there exist extensive barren hills with miscellaneous heaths and bushes under no management, which are mainly distributed in most areas of Zhejiang and north and southwest parts of Jiangsu Province. According to the statistical information of the landscape, there exist 43 800 km^2 barren hills in Zhejiang Province. Field investigation reveals that at least 1/3 of hilly vegetation, i. e. , about 14 600 km^2 （close to thecurrent area of Beijing） of such vegetation, has been severely damaged, unattended and in a state of natural recovery. If the economic forest - building is carried out, the barren hills can be restored, and the tremendous economic value can be achieved as well.
