通过研究同心县主要农作物需水与降水的耦合度及水分生态适应性，为制定合理的旱区种植制度决策方案提供理论依据。试验结果表明：同心县4种主要作物的需水与降水耦合度排序依次为：西瓜>马铃薯>玉米>油葵；生态适应性指数排序依次为：马铃薯>西瓜>玉米>油葵。
通過研究同心縣主要農作物需水與降水的耦閤度及水分生態適應性，為製定閤理的旱區種植製度決策方案提供理論依據。試驗結果錶明：同心縣4種主要作物的需水與降水耦閤度排序依次為：西瓜>馬鈴藷>玉米>油葵；生態適應性指數排序依次為：馬鈴藷>西瓜>玉米>油葵。

The coupling degree of the main crops' water demand and the rainfall and the water ecological adaptability in Tongxin County were studied to provide a theoretical basis for making a reasonable decision scheme of dryland cropping sys-tem. The test results show that the coupling degree ordering of 4 kinds of main crops' water demand and the rainfall is wa-termelon>potato>maize>oil sunflower and the ecological adaptability index ranking is potato>watermelon> maize>oil sunflower.
