摘要
农业被认为从南水北调中获益最大，但恰恰也是最主要的问题。谷物和其他粮食作物消耗掉了中国可用水总量的70％，创造出的GDP却只有15％。因此，在现有土地使用模式的基础上，即使谷物价格增加到三倍，南水北调的供水成本也使得其灌溉功能并不经济合算。
Agriculture, which stands to benefit most from the water transfer, is the major problem. Grain and other crops guzzle an enormous 70% share of China＇s total water availability, but contribute just 15% in return to China＇s GDP earnings. Based on current land--use patterns, therefore, the cost of providing water through any component of the south - north transfer scheme would make its use for irrigation uneconomic, even if grain prices trebled.
