| 摘 要： | 针对水资源核算方法的复杂性,结合城镇用水需求设计取水量、流域多年平均径流量等指标,笔者分析了水资源量概念的内在逻辑关系,并提出采用并行算法核算水资源量的观点.把贵阳城区作为水资源的需求主体,其取水半径在继续向外延伸;目前城区的用水需求量已达到5.8m3*s-1,约占所在南明河径流量(12m3*s-1)及猫跳河上游径流量(30m3*s-1)的1/7.依据可供对比的城区用水需求量、流域产汇流量的并行计算结果,能够直观地反映贵阳城区水资源量相对短缺程度的基本概况.

| Abstract: | Due to the complex of calculation methods about water resources,the authors analyzed the logical concept of water resource quantity,and put forward a new viewpoint on parallel calculation method based on main indexes,including water demand design and average runoff of drainage basin in the present work.Taking as a main body of water resource demand,Guiyang city,a provincial city zone in the southwest of China,gradually spreads its waterfetching radius to farther water area.The water demand of Guiyang is app... |
