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，冰雪灾害对毛竹的出笋数量有一定提高，但冰雪灾害对毛竹的高和粗生长存在着一定的影响，冰雪灾害对毛竹林土壤养分变化影响不大，但对土壤有机质和碱解氮含量有一定的影响。

Abstract: |
|
The number of phyllostachys pubescens shoots and the growth after Ice-snow disaster was investigated. The leaves of phyllostachys pubescens and soil samples were collected. Meanwhile the contents of N, P, K of the samples were analyzed. The results showed that the number of phyllostachys pubescens shoots had increased due to snow disaster, but the snow disaster had some impact on the height and stem growth. The snow disaster had little impact on soil nutrients of phyllostachys pubescens forest, but it had impact on soil organic matter and hydrolyzable nitrogen content.
