【摘要】 本文在分析和计算干旱地区地下水资源的基础上,提出生态警戒水位的概念。并讨论在无地质资料的条件下,干旱地区地下水资源量可通过设立若干地下水位观测网点进行计算。在分析植物的水分生理特征的基础上,提出保护荒漠绿洲生态系统的主要任务就是要调控地下水位稳定在盐渍化临界高水位以下和生态警戒水位以上的范围内。根据植物生态因子作用规律、生态位的概念等,提出可开采量概念,为生态水文学奠定基础。更多还原

【Abstract】 On the basis of analysis of the arid region water resources,we give out a theory of alert groundwater table.And discuss the method to calculate groundwater resources in arid region by analysis of the variation of grid groundwater table observation plot in the regions with littler hydrogeological data and without groundwater information.On the basis of analysis of plant hydrophysiological characteristics,we give out that the main task of revelation of the fragile ecosystem is to control the groundwater table in the limit between the alert groundwater table and the salinization water table.According to the water resources relation law,plant physiological effecting law and ecological local theory,the paper divide the groundwater resources into the renew water resources,ecowater resources and exploitable water resources.Above theory can promote the ecotone hydrology development.更多还原
