西北干旱区生态与环境极为脆弱,在绿洲开发过程中极易引起土壤盐渍化、土地沙化等生态与环境问题。本文在阐释绿洲及绿洲化等概念基础上,对西北干旱区绿洲化及其环境效应研究进行综述。针对绿洲、绿洲化等概念可操作性不强,绿洲化趋势研究数据时间序列较短及时间节点较少,绿洲化环境效应综合评估薄弱等问题,提出未来应在界定绿洲与绿洲化等基础上,加强绿洲化机制研究,应特别关注过度绿洲化问题。

Oasisization, which not only sh ows the expansion of oasis area but also the improvement of land productivity and land intensive level, is mainly the transition process from desert to oasis in arid region. However, the low level or disordered development of oasis may trigger a series of ecological problems like vegetation degradation and soil salinization. In this paper, three focus research fields including the concepts of oasis, oasisization and undue-oasisization, the driving mechanism of oasification, and the evaluation of environmental effects of oasi-sization are reviewed. It is found that there are some problems, such as the deficiency of quantitative concept of oasis and oasisization, the lack of oasisization data, and the comprehensive evaluation of oasisization environmental effects, needed to be solved.
