[例1]下列说法正确的是( ) A.水资源是指河流水、淡水湖泊水、浅层地下水 B.水资源是指陆地上各种可以被人们利用的淡水资源 C.水资源不包括冰川和深层地下水 D.静态水资源的循环周期长、更新缓慢,一般不宜开发利用 解析:水资源是指陆地上各种可以被人们利用的淡水资源。水资源除了河流水、淡水湖泊水、浅层地下水之外,还有冰川和深层地下水及咸水湖泊水等。只不过冰川和深层地下水及咸水湖泊水属于静态水资源而已,不能把水资源与目前人们主要利用的淡水资源混为一谈。静态水资源的循环周期长、更新缓慢,一般不
[Example 1] The following statement is correct () A. Water resources refer to river water, freshwater lake water, and shallow groundwater B. Water resources refer to various freshwater resources that can be used by people on land. C. Water resources do not include Glaciers and deep groundwater D. The cycle of static water resources is long and slowly updated. It is generally not suitable for development and utilization. Analysis: Water resources refer to various freshwater resources that can be used by people on the land. In addition to river water, freshwater lake water and shallow groundwater, water resources include glaciers, deep groundwater and saltwater lakes. However, glaciers, deep groundwater and brackish lake water are static water resources and cannot be confused with the freshwater resources that people currently use. The cycle of static water resources is long and slowly updated. It is generally not
