中文摘要	【目的】揭示乌兰布和沙漠1979年人工种植梭梭水分利用过程,以期为当地梭梭林的经营管理提供理论参考。【方法】利用PS-TDP8树木茎流监测系统和自动气象站对乌兰布和沙漠梭梭的液流变化及其周围的气象因子进行观测。【结果】梭梭晴天茎干液流日变化呈单峰型。春、夏、秋季梭梭茎干液流连日变化趋势一致,白天液流速率高于夜间,且夜间液流速率变化幅度小。5、7、9月时茎干直径12.5 cm的梭梭液流启动时间均早于直径8.95 cm的梭梭,平均液流速率也较高。茎干直径12.5 cm的梭梭在5、7、9月的液流峰值分别为2.90、4.18、 3.15 cm/h,液流日累积量分别为12.29、14.23、9.44 L;茎干直径8.95 cm的梭梭同时期液流峰值分别为1.06、 1.20、1.07 cm/h,液流日累积量分别为2.84、3.68、3.10 L;同一茎干直径梭梭在7月的液流日累积量最大。梭梭液流日变化中,晴天为单峰型,雨天呈双峰型;雨天液流峰值及夜间液流均低于晴天。夏季茎干液流启动时间最早,峰值出现时间最早,峰值最大;春季液流启动时间最晚,峰值出现时间最晚,峰值最小。春、夏、秋季梭梭夜间均存在微弱液流。【结论】影响梭梭液流速率的气象因子中,春季主要为太阳总辐射、空气温度、风速,夏季主要为太阳总辐射、空气相对湿度、风速,秋季主要为太阳总辐射、空气温度。
英文摘要	【Objective】The water use process of artificially planted Haloxylon ammodendron (C.A.Mey.) Bunge in 1979 in Ulan Buh Desert was revealed to provide a theoretical support for the management of the local H. ammodendron forest. 【Method】The PS-TDP8 tree stem flow monitoring system and automatic meteorological station were used to observe the sap flow changes of H. ammodendron in Ulan Buh Desert and surrounding meteorological factors.【Result】Diurnal variations of the stem sap flow of H. ammodendron during sunny days showed asingle peak. The daily change trend of H. ammodendron stem sap flow during spring,summer and autumn was consistent. The sap flow rate during the day was higher than that during the night; however,the sap flow rate at night varied slightly. In May,July and September,the sap flow of H. ammodendron with a stem diameter of 12.5 cm started earlier than that with a stem diameter of 8.95 cm, and the average sap flow rate was also higher. The peak sap flow of H. ammodendron with a stem diameter of 12.5 cm in May,July and September was 2.90,4.18 and 3.15 cm/h,respectively,and daily cumulative volumes of sap flow were 12.29,14.23 and 9.44 L,respectively. The peak sap flow of H. ammodendron with a diameter of 8.95 cm during the same period was 1.06,1.20 and 1.07 cm/h,respectively,and daily cumulative volumes of sap flow were 2.84,3.68 and 3.10 L,respectively; H. ammodendron Bunge with the same diameter had the largest daily accumulation of sap flow in July. The sap flow of H. ammodendron wassingle-peakedon sunny days anddouble-peakedon rainy days. The peak sap flow on rainy days and nights was lower than that on sunny days. In summer,the stem sap flow started the earliest,the peak appeared the earliest,and the peak was the largest. The spring sap flow started the latest,the peak appeared the latest,and the peak was the smallest. Whether it was spring,summer or autumn,there was a weak liquid flow in H. ammodendron at night.【Conclusion】In spring,the meteorological factors affecting the flow rate of H. ammodendron mainly included solar radiation,air temperature,and wind speed. In summer,the meteorological factors affecting the flow rate of H. ammodendron mainly included solar total radiation,relative humidity of air,and wind speed. In autumn,the meteorological factors affecting the flow rate of H. ammodendron mainly included solar total radiation and air temperature.
