摘要:
采用快速称重法对库布齐沙漠人工柠条、沙枣和不同林龄的人工梭梭以及天然植物油蒿蒸腾速率日进程的季节变化进行了测定,并同时测定了气温、小枝含水率等相关环境因子.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;对几种植物种的蒸腾速率与气温和小枝含水率进行回归分析表明,除4年生梭梭外,均呈现出不同程度的相关性,其中油蒿的复相关系数最高为0.925,其次是年生梭梭为0.79,2年生梭梭的相关系数(除4年生梭梭外)在几种植物中最低为0.426.沙枣和柠条均与气温呈直线相关,而与小枝含水率的相关性极低.沙枣和柠条相比,与气温的相关程度更高.
Abstract:
Celerity metage was used to mensure evapotranspiration rate in different season of artifical Caragana korshinskii,Elaeagnus angustifolia,Haloxylon ammodendron in different age and natural Artemisia ordosica Krasch in Kubuqi desert,air temperature and twig’s water containing was mensured in synchronization.The result shows that transpiration rate of various plant has distinct differences because of season changing.Regression analysis to vegetation’s transpiration rate with air temperature and moisture content of twig indicate different degree of relativity except for four-year-old Haloxylon ammodendron.Artemisia ordosica Krasch’s correlation coefficient is highest above all,about 0.925,the second one is three-year-old Haloxylon ammodendron,about 0.793,two-year-old Haloxylon ammodendron’s correlation coefficient(except the four-year-ones) is the smallest among those plants,about 0.426.Elaeagnus angustifolia and Caragana korshinskii are all linearity relative with temperature,but there is less relativity with small branch’s water containing rate.Elaeagnus anugustifolia is firmly relative with temperature compared with Carragana korshinskii.
