地下水与植被关系的研究进展

Research progress on relation between groundwater and vegetation

地下水与植被之间有着复杂的关系,它涉及地下水、土壤、植被等相互之间的动态平衡。地下水的变化会引起土壤水盐变化而直接影响植被的生长、分布和演替。本文系统地总结了地下水与土壤含水量、土壤含盐量、天然植被、地表荒漠化关系等诸多方面的影响研究进展,并探讨了生态地下水埋深对植被的重要作用。认为针对地下水变化引起的生态负效应,开展地下水与植被的关系研究,认识和理解植被退化的过程和机制,是应对气候变化和人类活动影响下地下水管理和生态保护的重要工具,最后指出地下水生态效应仍是今后亟需加强的研究方向。

There is a complex relation between groundwater and vegetation, which involves dynamic balance between groundwater, soil and vegetation. The change of groundwater can cause the transport of water - salt in soil, this outcome influences the growth, distribution and succession of vegetation. This paper firstly summarized the current progress of study on relation between groundwater and soil moisture, soil salinity, vegetation, surface desertification etc. Secondly, it studied the important role of rational groundwater depth on vegetation. The study on relationship between groundwater and vegetation and understanding of vegetation degradation process and mechanism aimed at ecological negative effects caused by groundwater are an important tool important of groundwater management and ecosystem protection so as to copy with future climate change and human activity . Finally, it indicated that eeo-effects caused by groundwater is still the future research direction.
