Abstract

Abstract:

In order to study the change law of sap flow and its influencing factors in sunny and rainy days and reveal the water consumption characteristics of Ammopiptanthus mongolicus in Ulan Buhe desert， the diurnal variation of sap flow rate of Ammopiptanthus mongolicus was monitored by thermal diffusion probe（TDP） stem sap flow meter， and the diurnal variation of meteorological factors such as air temperature and air relative humidity was synchronously monitored by automatic weather station. The diurnal variation of soil factors was measured by soil temperature and humidity automatic monitor， and the diurnal variation characteristics of sap flow of Ammopiptanthus mongolicus with different diameters under different weather conditions and their relationship with environmental factors were studied. The results showed that the sap flow of Ammopiptanthus mongolicus was high in the daytime， and there was sap flow at night， but the sap flow rate was small and did not change much. The larger the diameter of Ammopiptanthus mongolicus， the greater the daily average sap flow rate. The sap flow curves in sunny days and rainy days showed“single peak type”and“double peak type”， respectively，the daily mean value of sap flow rate in sunny days was higher than that in rainy days. Under sunny and rainy conditions， the sap flow rate of Ammopiptanthus mongolicus was significantly positively correlated with solar radiation， soil temperature， air temperature and saturated water-air pressure difference， and was significantly negatively correlated with air relative humidity， and had no significant correlation with soil water content. The regression equation analysis showed that the solar radiation had the greatest influence on the sap flow rate in sunny days， which could explain 89.1% of the change of sap flow alone， and the soil temperature had the greatest influence on the sap flow rate in rainy days， which could explain 85.8% of the change of sap flow alone. In summary， the change trend of sap flow rate of Ammopiptanthus mongolicus in the Ulan Buh desert was different between sunny and rainy days. The sap flow rate was mainly affected by solar radiation in sunny days and soil temperature in rainy days. Whether sunny or rainy days， the change of sap flow rate was positively correlated with solar radiation， soil temperature， air temperature and saturated water vapor pressure deficit， negatively correlated with relative humidity， and not significantly correlated with soil water content. Above results were of great significance for clarifying the water consumption law of Ammopiptanthus mongolicus in Ulan Buh desert， and had certain theoretical significance for biodiversity conservation and regional vegetation construction.

摘要：

为揭示乌兰布和沙漠沙冬青耗水特征，研究沙冬青晴天和雨天液流变化规律及其影响因素，采用热扩散树干液流仪监测沙冬青液流速率日变化，并利用自动气象站同步监测空气温度、空气相对湿度等气象因子日变化，利用土壤温湿度自动监测仪测定土壤因子日变化，研究不同直径沙冬青液流在不同天气条件下的日变化特征及其与环境因子的关系。结果表明，沙冬青白天液流较高，夜晚存在液流，但液流速率小且变化不大。沙冬青直径越大，日均液流速率也越大；晴天与雨天沙冬青液流变化曲线分别呈“单峰型”与“双峰型”，晴天液流速率日均值高于雨天。晴天和雨天条件下，沙冬青液流速率与太阳辐射、土壤温度、空气温度、饱和水气压差呈显著正相关，与空气相对湿度呈显著负相关，与土壤含水量相关性不显著。回归方程分析表明，对沙冬青晴天液流速率影响最大的是太阳辐射，可单独解释液流变化的89.1%，对雨天液流速率影响最大的是土壤温度，可单独解释液流变化的85.8%。综上可知，乌兰布和沙漠沙冬青液流速率在晴天与雨天的变化趋势存在差异，晴天沙冬青液流速率主要受太阳辐射影响，雨天主要受土壤温度影响，晴天和雨天液流速率的变化与太阳辐射、土壤温度、空气温度、饱和水汽压亏缺呈正相关，与相对湿度呈负相关，与土壤含水量相关性不显著。研究结果对于明确乌兰布和沙漠沙冬青耗水规律具有重要意义，对生物多样性保育和区域植被建设具有一定理论意义。
