| 摘要: |
| 在前人承载力研究的基础上提出了承载力的新见解，定义了承载力的四要素，并根据农业生产的实际情况提出了灌区农业水资源承载力的概念，建立了农业水资源承载力计算模型，该模型计算时考虑了农业水资源的两个特殊性，即各种作物的被承载能力及作物的需水和供水过程。最后将模型应用于河南省第三濮清南灌区，验证了模型的正确性。 |

| Abstract: |
| Based on the previously study on the carrying capacity,the paper put forward new comprehension about the carrying capacity,and defined four factors of the carrying capacity;then the paper brought forward the concepts of the agricultural water resources carrying capacity in irrigation area and established the calculation model of the agricultural water resources carrying capacity.The model considered two particularities about the agricultural water resources:the carrying capacity between different crops and the water demand and supply process.Finally the model was used in the third Pu-Qing-Nan irrigation area,Henan province,the correctness of the model was validated. |
| Key words: irrigation area the agricultural water resources carrying capacity quantitative model |
