摘　　要：2008年春天我国南方发生的严重雨雪冰冻天气对毛竹林造成严重危害,作者调查了富阳区毛竹林的受灾特征及其影响因子,并在此基础上研究了不同施肥处理对受灾毛竹林恢复生长的影响。结果表明:1)毛竹林受灾程度与其所处的海拔、坡向、坡度、坡位、竹林地土壤厚度等环境因子以及毛竹林林分结构密切相关,其中海拔高度的影响最为显著;2)不同施肥处理对毛竹林恢复生长的影响差异显著,在试验的几个处理中,以在高海拔(500 m)区使用大剂量施肥(生物肥料160 kg/667 m^2和复合肥40 kg/667 m^2)和在低海拔(300 m)区使用小剂量施肥(生物肥料100 kg/667 m^2和复合肥20 kg/667 m^2)的新竹产量为高,每年产量分别达到2 243.3 kg/667 m^2和2 258.3 kg/667 m^2,分别比对照增加65.4%和63.3%;3)高海拔地区的毛竹林因受损严重,在适当施肥后其新竹萌发量比低海拔地区的要高,但立竹直径明显低于低海拔地区。Considering that the rain and snow freezing weather in the spring of 2008 caused the severe damage on Phyllostachys pubescens forest,this paper investigated the characteristics of damages suffered by stands,and then studied the impacts of different fertilization treatments on the restoring growth of affected stands.The results showed that： 1） The damage suffered by Ph.pubescens stands were closely related to environmental factors such as the altitude, slope direction, slope angle, slope position and soil thickness of bamboo stands as well as bamboo stands structure, among which altitude was the most significant factor; 2） Different fertilization treatments had significantly varied effects on the restoring growth of Ph.pubescens stands. Under the treatment of higher dose of fertilizer at high altitude （ bio-fertilizer at 160 kg/ha and compound fertilizer at 40 kg/ha） and the treatment of using lower dose of fertilizer at low altitude （ bio-fertilizer at 100 kg/ha and compound fertilizer at 20 kg/h a ） ,the Ph.pubescens stands had the highest new bamboo culms yield,which was 2 243. 3 kg/ha and 2 258. 3 kg/ha,65. 4 % and 63. 3% higher than the control, respectively. 3） The bamboo stands in the high altitude area were seriously damaged, and after the appropriate fertilization, the new bamboo sprouting rate was higher than that in the low altitude area, but the diameter of new bamboo culms was obviously less than that in the low altitude area.
