| 摘 要： | 蒸腾是植株主要的耗水形式.以六盘山北侧的华北落叶松为研究对象,采用当前国内外较先进的热扩散式树干边材液流测定技术从单株水平上探讨了华北落叶松的蒸腾速率特性以及其与环境因子之间的影响机理.就气象因子和蒸腾速率进行了分析,提出了气象因子和华北落叶松蒸腾耗水的数学模型.应用Matlab软件对华北落叶松进行了模糊蒸腾模型的设计和仿真.研究结果表明,空气相对湿度和空气温度是影响华北落叶松蒸腾速率的直接因子,太阳辐射式通过改变空气湿度和空气温度进而来影响华北落叶松的燕腾速率.

| Abstract: | Transpiration water is the main mode of plant water consumption. This study takes Larix principis-rupprechtii Mayr in the north of Liupanshan Mountains as a study object. The water consumption characteristics of Larix principis-rupprechtii Mayr are studied using advanced SL??F technology and then the relationship between transpiration rate and environmental factors is analyzed. A regressive model is constructed through analyzing the meteoric factors. The fuzzy transpiration model based on Matlab is designed and simulated. Results indicate that air temperature and air relative humidity directly affect transpiration rate.Solar radiation intensity can affect the transpiration rate of Larix principis-rupprechtii Mayr by influencing air temperature and air relative humidity . |
