在界定沙区微区概念的基础上,分析了沙区微区集水的形成、转化以及对干旱沙区生态水文方面的重要作用,综述了国内外对微区集水在土壤水文、土壤发育和微区植被生长等方面的研究动态以及沙区微区集水在农林业和生态修复上的应用,指出沙区微区生态水文过程今后的研究重点在于对微区水文过程做出更加准确的量化分析,提出沙区具有完整意义的水文模型,为准确定量评价沙区水分循环和生态恢复提供理论依据。
View on process of water catchment and its vegetation effects in micro-region of sandy area
This paper defines the concept of micro-region in sandy area, on the basis of which analyzes the formation and transformation of micro-water harvesting and its important role in arid ecological hydrology. Additionally, it presents a summary the domestic and foreign research trends on the effects of micro catchment in soil hydrology, soil development and its application in agroforestry and ecological restoration. Overall, the future research trend lies in the more accurate quantitative analysis in the process of micro zone hydrology and indicates the complete significance in sandy hydrological models in order to provide a theoretical foundation for accurate quantitative evaluation of the hydrological cycle and ecological restoration in sandy areas.
