| 摘 要： | 本文采用快速称重法对毛乌素沙地的臭柏、樟子松、油蒿、沙柳蒸腾作用日进程的季节变化进行了测定，并同时测定了小枝含水量及气温、土壤含水率等因子。结果表明：不同植物种其蒸腾速率特征因季节变化存在明显差异；蒸腾速率与气温密切相关。四种植物的蒸腾速率，油蒿最高，臭柏最低。

| Abstract: | Transpiration rate of four plants ( Artemisia ordosica,Sabina vulgaris,Salix psymophila,Pinus sylvistris var. mongolica) in MaoWuSu sands were measured with Quick weighing technique in July,August and September.In addition,air temperature,soil water content,branch water content and so on were measured at the same time.The results show that transpiration rates vary greatly with the change of seasons for different species,and are closely related to air temperature,soil water content and branch water content.Among these species, Artemisia ordosmica was the highest transpiration plant,and Sabina vulgaris was the lowest transpiration plant. |
