摘    要:
盐渍土区生态、水文过程及其耦合作用机制是当前盐渍化、次生盐渍化产生的根源。目前的研究主要是从土壤水盐动态、地表水文格局及其生态效应、生态地下水位、生态需水等角度对盐渍土区生态水文过程进行研究和探讨,尚未能揭示清楚盐渍土形成和演化的生态水文学机制。未来需要就生态、水文过程及其耦合作用机制,地表水、地下水以及土壤水之间的相互转化关系及其生态效应,基于生态水文过程的生态需水,以及构建流域尺度盐渍化生态水文模型等进行深入研究,以便为盐渍土区生态环境的维护和恢复、生态与社会经济的和谐提供理论与实践指导。

关 键 词:盐渍土区  生态水文学  生态需水  盐渍化效应

Abstract:
The ecological processes,hydrological processes and the coupling effects in different spatial and temporal scalings are the main causes of some eco-environmental problems,especially the soil salinization in the saline soil regions.The study on the effects of eco-hydrological processes on soil salinization includes the following topics:soil water and solute transport,the pattern of the surface water and its ecological effect,the ecological groundwater level and eco-environmental water requirement.However,one has also to reveal the eco-hydrological mechanism of the saline soil formation and evolution.The future topics on the eco-hydrological processes effect on the saline soil region should include:ecological process,hydrological process and the coupling effect between them;the transfer between the surface water,groundwater and soil water,with ecological effect;the eco-environmental water requirement based on the eco-hydrological process;the eco-hydrological model in the catchment.
Keywords:saline soil region  eco-hydrology  ecological water requirement  salinization effect
