摘要
浙江省常山县有马尾松林18462hm^2，其林分生产力低下，植物群落结构单调、土壤冲刷严重、松毛虫发生频繁。从20世纪90年代开始，根据不同情况，分别采取封山育林、补植阔叶树、营造阔叶林、工程治理等措施，修复生态系统，调查统计结果至2004年，水土流失面积大幅度减少、小溪流水时间延长15-20d、松毛虫发生率处在0．1％以下。
Pinus massoniana forest with the area of 18, 462hm^2 of Changshan county in Zhejiang province has the characteristics of low productivity of stand, monotonous vegetation structure, severe soil erosion, frequent occurrence of Dendrolimus pinidiatrea （pine- moth）. Since 1990 of twenty century, some measures including closing off, replanting broadleaf trees, cultivating broadleaf forest, and engineering control have been adopted under different situations. The statistic result until the year of 2004 indicated that soil erosion area reduced tremendously, the time of flowing water prolonged 15 - 20 hours, and incidence of Dendrolimus pinidiatrea was below 0.1%.
