| 1. | Ground water table 地下水位表 |
| 2. | Water and salt transport in sand - layered soil under evaporation with the shallow under ground water table 蒸发条件下浅层地下水埋深夹砂层土壤水盐运移特性研究 |
| 3. | Ground water table influences the infiltration capacities of frozen soils by its influence on ground soil moisture 地下水位对冻融土壤入渗能力的影响通过对土壤含水量的影响实现。 |
| 4. | Consequently , the dynamic of ground water table and water quality has an intense influence on the growth of vegetation 因此地下水水位和水质的动态强烈地影响到植被的发育和动态。 |
| 5. | Therefore , the spatial and temporal dynamic of the soil water and salinity , the ground water table and salt concentration are main factors affecting the oasis stability 因此,干旱区流域内土壤水盐和地下水水位、盐分含量的动态变化成为影响绿洲稳定性的重要因素。 |
| 6. | 2 . the change of water content and salt concentration in soil is a dynamic process of balanced accumulation and consumption . it is influenced markedly by the ground water table 而180 《 40cm以下土层主要受地下水的水位、水质影响,因为地下水的总盐含量变化也较小。 |
| 7. | During the growing season , the ground water tables at each sampling point are falling , but the total salinity of the soil does not change much 这是因为180 240cm以上土层是根系大量分布的层次,群落中的植物均以盐生植物为主,它们在生长过程中能够吸收土壤中的大量盐分离子而保持正常生长。 |
| 8. | The spatial and temporal distribution of water resource is the dominant factor that influences the dynamic of ground water . the influence displays mainly in the seasonal and spatial dynamic of ground water table and water quality 水资源在时空上的分配是地下水动态的主要影响因素,主要表现在地下水位、水质在季节和空间上的动态变化。 |
| 9. | For this reason , to analyze the spatial and temporal dynamic of ground water table and water quality beneath the typical phytocommunity in particular areas , will be helpful to probe into the dynamic formation of soil moisture and salinity , and to understand the spatial variation of vegetation 因此,分析区域内典型植物群落的地下水水位、水质在时空上的动态变化,有助于探讨土壤水盐动态变化的形成条件,揭示植被在空间上梯度变化的原因。 |
| 10. | Based on analyzing the water resource situation and water environment problems such as water pollution , ground water table dropping , seawater invading and local water system degradation in shandong peninsula urban agglomeration ( spua ) , this article puts forward some strategies for sustainable water utilization in spua accompanying the rapid urbanization 摘要在分析山东半岛城市群水资源状况和地下水位下降、海水入侵、水域污染及自然生态失衡等水环境问题的基础上,提出了水资源约束下山东半岛城市群发展对策。 |
