中文摘要: |
引入农业标准产量概念,建立农业水分生产率评价知识模型,以省域为分析单元,从灌溉强度和灌溉广度两个方面研究农业水分生产率的变化,评价区域农业水分生产率状态,并根据不同区域水分生产率形成要素特征进行灌溉策略分析。 |
英文摘要: |
The concept of agricultural standard yield was introduced,and the knowledge model of agricultural water productivity ratio evaluation was set up.From the aspect of irrigation intensity and extent,the changes of agricultural water productivity ratio of different provinces in China were studied,the state of regional agricultural water productivity ratio was evaluated,and the corresponding irrigation strategies were analyzed according to the basic characters of regional water productivity ratio. |
