, 2009 以全根系挖掘法,对共生于原始盐生荒漠生境中的多枝柽柳[Tamarix ramosissima(Ledeb.)]、梭梭[Haloxylon ammoden-dron(C.A.Mey.)Bunge]、琵琶柴[Reaumuria soongorica(Pall.)Maxim.]的根系分布特征进行了研究;对降水引发的湿润-干旱周期中植物同化枝水势、蒸腾速率的变化过程进行了跟踪观测,并据此计算3种植物的水分胁迫效应指数和土壤-植物系统导水度,以最终确定3种植物用水策略和其对降水的响应特征。研究结果表明 ...

, 2013 利用2008年6-8月微波辐射计的观测资料和探空数据,对反演得到的温、湿度廓线进行对比分析,得出温、湿度廓线与探空数据具有很好的相关性,两种设备观测的水汽廓线总体趋势一致.微波辐射计观测的乌鲁木齐夏季水汽总量(PWV)呈明显的日循环特征,PWV平均为21.66 mm,从04:00-15:00逐渐减小,从15:00-23:00逐渐增加,最大值为22.44mm,最小值为20.89 mm,日变幅为1.55 mm,变化率7.1％.乌鲁木齐夏季降水主要发生在夜间,尤其是后半夜,这与PWV的日变化基本一致 ...

, 2016 为探明降雨条件下坡面薄层水流阻力特性，分析雨强对坡面流阻力的综合作用，以流体力学和水力学基本 理论为依据，通过５个坡度和８个流量、４个雨强组合条件下的模拟降雨试验，系统研究了降雨条件下坡面薄层水 流阻力规律。结果表明：相同雨强条件下，阻力系数随着坡度的增加呈现先增加后减小的趋势，随着流量、水深的 增大而逐渐减小，最终稳定在０．０２５左右；相同坡度下，坡面薄层水流的阻力系数随着降雨强度、放水流量的增大 而减小；降雨强度在一定程度上影响阻力系数与弗汝德数幂函数关系的离散性。在本试验条件下，薄层水流都处 于 ...
