| Abstract: | Taking the Guanzhong irrigating region for an example the crop ecological demand of soil and water resources were analysised in order to make the balance of the soil and water resources and best promote its utilization and its production efficiency in regional soil water exploitation and utilization.Firstly,the soil and water resources were evaluated and classified;secondly the regular pattern of the crop ecological demand were discussed;finally the countermeasures of coordinating between soil water resources and crops and the optinum thought of its utilization were suggested. |
