摘要
生态需水与荒漠化之间的关系错综复杂,制定适宜的生态补水策略是防治荒漠化的核心和难点。为此,以荒漠地区的典型河流孔雀河为例,运用综合分析法结合ArcGIS软件,从孔雀河来水状况、用水情况、土地利用类型的变化态势及保护孔雀河的重要意义等方面辩证分析确定孔雀河的生态需水对象,采用Tennant法、定额法确定适宜的生态需水量,并提出与地区水资源和生态环境相适配的生态需水保障措施,为荒漠化地区河流的生态需水及保障措施研究提供参考。
The relationship between ecological water demand and desertification is very complicated.To formulate appropriate ecological water replenishment strategy is the core and difficult point of desertification control.Taking Kongque River,a typical river in desert area,as the research object,this paper adopts comprehensive analysis method and ArcGIS software to dialectically analyze and determine the ecological water demand object of Kongque River from the aspects of inflow water status,water use status,change trend of land use type and the significance of protecting Kongque River.Tennant method and quota method are used to determine the appropriate ecological water demand.The ecological water demand protection measures matched with the regional water resource and ecological environment are put forward,which provides a reference for the study of ecological water demand and protection measures of rivers in desertification areas.
