摘　　要：设置标准地调查毛竹林在冰雪灾害后的出笋及生长情况,采集土壤样品和毛竹叶子样品并分析其N、P、K含量等。结果表明,冰雪灾害后毛竹的出笋数量提高,新竹比例提高10个百分点;新竹平均高减少1.6 m,胸径减少2.2 cm;新竹叶片全N、全P含量差异不显著,全K含量1.400%比对照的1.734%减少了0.334个百分点,粗灰分含量9.34%比对照的6.82%增加了2.52个百分点。The number of Phyllostachys pubescens shoots and the growth after ice-snow disaster was investigated in the standard plots.The leaves of P.pubescens and soil samples were collected to analyze their contents of N,P,K.The results showed that the number of P.pubescens shoots had increased 10% due to ice-snow disaster.The average height and DBH of P.pubescens shoots had decreased 1.6 m and 2.2 cm respectively.There existed no significant differences between the contents of N and P in the leaves samples.The content of K（1.400%） in the leaves samples had reduced 0.334% than the control（0.334%）,and the content of coarse ash（9.34%） had increased 2.52% than the control（6.82%）.
