| 摘 要： | 采用快速离体称重法,测定皇甫川流域本氏针茅每日6:00-19:00蒸腾强度的日动态;用自动气象站同步连续监测太阳总辐射、空气温度、空气相对湿度、风速、10 cm处土壤温度等环境因子;用LI-6400便携式光合系统同步测定本氏针茅每日6:00-19:00的叶蒸腾速率、气孔导度等因子,并用Excel 2003,Visual C++6.0和SPSS 13.0处理所测定数据.通过分析本氏针茅每1 h单株蒸腾量与环境因子以及植物特性因子之间的关系,建立了皇甫川流域单株本氏针茅瞬时蒸腾量数学模型.通过对模型评价指标进行计算及分析,认为该模型拟合优度较好,可以获得满意的数值模拟结果.在此基础上,建立了单株本氏针茅的日蒸腾量数学模型.

| Abstract: | Transpiration of Stipa bungeana in Huangfuchuan watershed was measured using isolated weighing method.Synchronous environmental factors such as incident solar radiation,air temperature,relative air humidity,wind speed,and soil temperature at depth of 10cm were recorded continuously using automatic weather station.Leaf transpiration rate and leaf stomatal conductance were also measured using LI-6400.The data were then processed using Excel 2003,Visual C++ 6.0,and SPSS 13.0. The individual transpiration model was developed by analyzing the correlation between transpiration and environmental factors along with plant characteristic factors.The model is evaluated to be good based on the performance indices.The mathematical model of daily transpiration for S.bungeana in Huangfuchuan watershed was developed based on the model of hourly transpiration. |
