摘要
为探讨山区不同坡位对毛竹林小气候及地上生长的影响,对会同县山区毛竹林进行调查,结果表明:不同坡位的毛竹林其气温、极端最高温度和不同土壤深度的地温以及降水量,山坡均高于山谷,极端最低温度和相对湿度,山坡则低于山谷;相同径级的毛竹个体结构生长差异明显,不同径级的毛竹标准株单株生物量山谷比山坡重,增加5.11 kg/株。相同径级的毛竹单株其平均枝下高、秆重、全重、总节数、枝重、胸壁厚、全高、枝下节间长,山谷均大于山坡3.3%~17.7%,但叶重则山谷小于山坡9.9%。
To explore the effect of different slope positions on moso bamboo forest microclimate and the ground to grow,the moso bamboo forest in Huitong County mountainous area was investigated.The results showed that the temperature,extreme maximum temperature and ground temperature in different soil depth and rainfall of the moso bamboo forest in slope were higher than those in the valley,and the extreme minimum temperature and relative humidity in slope were below those in the valley.the growth of moso bamboo individual with same diameter had obvious difference,and the individual biomass of moso bamboo with different diameter in valley was larger than that in slope,which increased 5.11 kg per plant.For the average under branch height,stem weight per plant,total weight,total number of section,branch weight,chest wall thickness,total height,under branch internode length of moso bamboo individual with same diameter,the valley were greater than the slope of 3.3% ~ 17.7%,but for leaf weight the valley was less than the slope of 9.9%.
