| 1. | Main progress of research on hydrologic processes and prediction models 水文过程及模型研究主要进展 |
| 2. | Land - surface hydrologic processes are not only the main participants in climate change but are effected by the change 气候变化中陆面水文过程既是重要的参与者,同时也受到这些变化的影响。 |
| 3. | Land surface hydrologic process is one of the crucial processes which controls the land surface process and the land - atmosphere interaction 陆面水文过程是制约整个陆面过程及其陆气相互作用的关键过程之一 |
| 4. | The hydrologic processes have been described by regular methods of internal determinacy or external randomness or both of them for a long time 长期以来,一直采用传统的确定性或随机性或两者结合的方法来描述水文过程,揭示水文系统的内在确定性规律和外在随机性规律。 |
| 5. | One of the key research areas in modem ecohydrology is studying the feedbacks beween vegetation dynamics in structure , distribution , and succession and hydrologic processes at multiple spatial and temporal scales 摘要植被变化与流域水文过程构成一个反馈调节系统,是目前生态水文学研究的重点对象。 |
| 6. | In this paper , starting with the physical mechanics of land surface hydrologic process and the introduction of the theory in probability statistic distribution , an analytical expression of heterogeneous evapotranspiration efficiency is given which takes heterogeneous soil water content ' s subgrid scale spatial variability into account , through which the parameterization scheme of subgrid scale soil surface ' s evapotranspiration efficiency ( which is generally called mosaic method ) is modified to a statistic - dynamic scheme in which a whole heterogeneity of the grid region is considered 本文从陆面水文过程的物理机制出发,引进概率统计分布理论,推导出一种由非均匀土壤含水量次网格尺度空间变率所形成的非均匀蒸发散率解析表达式,从而将通常的次网格尺度地表蒸散率的参数化方案( mosaic方法) ,改进为考虑网格区整体非均匀性的统计-动力参数化方案。 |
| 7. | Developing and establishing macro - scale distributed hydrological model are required in order to make certain the regional water and energy cycle , study and resolve the hydrology and water resources problems under the changing environment according to the climatic prediction of gcm . as a branch of hydrologic cycle , land - surface hydrologic processes are nearly relative to atmospheric circle by water and energy exchange between land - surface and atmosphere 为了确定大尺度区域水文循环及能量收支、能够根据gcm给出的气候预测,研究和解决变化环境中的水文水资源问题,评估和监测大流域的径流过程和水资源量的动态变化规律,需要研制和建立大尺度分布式水文模型。 |
