| 摘 要： | 本文以大豆、花生、玉米、甘薯四作物为例，用土壤－植物－大气连续体（ＳＰＡＣ）理论分析作物水势分布物点及其耐旱性。结果表明：植物叶水势是植物水分状况的较好的生理指标，作物根、叶间水势差较大，叶位间水势差小。不同的作物叶片水势差异显著，作物耐旱性越强，其叶片水势越高。

| Abstract: | The characteristics of water potential and draught of soyean,pennut,corn and sweot was reported with SPAC.The results showed that leaf water potential of crops was a physical physiologial index refecting the water holding capacity of crop,the difference of water contents between roots and laves of crops was signtient and that among leaves was litle.The difference of leaves potential was outstanding among crops,that was more hight and crops'draught ladurence was more strengthen. |

| Keywords: | Leaves' water potential Drought proof Distribution |
