摘　　要：定位研究位于浙江省富阳市的不同结构毛竹林,2003 年夏季林内气温的日变动状况。结果表明:毛竹林内以日最低气温的变异幅度最大,日最高气温次之,日均气温最小;毛竹纯林内日均最低气温21.20℃,低于竹阔混交林1.32℃,日均最高气温为29.67℃,低于竹阔混交林1.03℃。毛竹林内最低气温主要出现在凌晨 4:00￣6:00,毛竹纯林调节林内最低气温的效应值与栎林相似约-0.3℃,竹阔混交林效应值约1.25℃。方差分析显示毛竹纯林、竹阔混交林、茶园3类林分间的日均气温差异极显著,日最低气温差异显著。This paper deals with a studied on daily variation of summer air temperature in different structures of Phyllostachys pubescens stands sited in Fuyang county of Zhejiang province in period from June 10 to July 15 in 2003. Results showed： the variation range of the lowest daily temperature in pure Phyllostachys pubescens stands was the broadest, However the highest daily temperature inferior to the lowest daily temperature and daily average temperature is the minimum; The average of the lowest＇ daily temperature of inside pure Phyllostachys pubescens stands was 21.20℃ that lower than mixed Phyllostachys pubescens with broadleaved tree stands （mixed stands as follow）was 1.32℃, While the average of the highest daily temperature of inside pure Phyllostachys pubescens stands was 29.67℃ that lower than mixed stands was 1 .03℃. Air temperature of the daily lowest in inner stands of Phyllostachys pubescens stands appeared at 4：00-6：00, Meanwhile it had special ability for adjusting the lowest air temperature in pure Phyllostachys pubescens stands, that the efficiency value nearly -0.3 ℃ was similarly to oak stands while it was 1.25 ℃ of mixed stands. ANOVA results showed it existed the extremely obviously difference of the diurnal average air temperature among in pure Phyllostachys pubescens stands, mixed stands and tea plantation garden, However existed obviously difference of diurnal the lowest air temperature in above three stands.
