那我们基本上明白了，human resource 是表示人力资源，是一种比较笼统的人力供应情况，而human source 则表示与人类有关的某些事物的来源，比如感染源是人类的禽流感 human source of bird flu.
water resource 表示水力资源，是一种关于综合水量的一种状况，water source则是指某个具体水源，比如自来水的水源，河流的源头等等。
英文解释其区别如下：
source means that anything or place from which something comes, or is obtained. For example: Which foods are sources of calcium?
resource means that a source of supply, support, or aid that can be readily drawn upon when needed. For example: Dr. Yang is a man of resource.
