| 摘 要： | 探讨了广西弄岗自然保护区不同演替阶段群落不同梯度的气温、湿度、土壤温度、光照强度的日变化特征，结果表明各演替群落的平均气温，最高温度，最低温度，气温上升和下降的速度随着群落演替的进展呈下降趋势，各群落的气温垂直变化一般随高度增加而增加；各演替阶段群落的土壤5cm处的温度变化呈不规则的单峰曲线；随着演替的进展，各群落的空气相对湿度增大，空气相对湿度的变幅随着演替的进展而变小；一般来说，随着高度的增加，各演替阶段的光照强度也增加。

| Abstract: | The main climate factors, such as air temperature(AT),relative humidity(RH), soil temperature(ST) and light intensity(LI) are studied in different successive communities in karst areas in Nonggang,Guangxi. The results show that: 1)the mean, maximum and minimum AT, and the rate of diurnal variation of AT drop with the evolution of the communities and the vertical variation of AT increases with the height; 2)diurnal variation of ST in every successive community has only one peak; 3)as the communities develop, RH is increasing and the variation of RH becomes small; 4)LI also increases with the height. |
