| Abstract: |
| Based on statistical information and fieldwork investigation,applying analytic hierarchical process theory and taking the Tarim River Basin as a research unit,this paper established the mathematical model and indicator system for integrated evaluation of agricultural water-saving potential.The indictor system includes five aspects such as socio-economic,hydrology and water resources,agricultural water use efficiency,and the extent of agricultural water-saving development and the ecological environment.The evaluating model and the indicator system are applied to evaluate synthetically the agricultural water saving potential in Tarim River Basin.The evaluation results showed that level of agricultural water-saving potential in 2003 increased by 49% compared to that in 1996,and by 17% compared to that of 2000 in the basin,indicating that with the implementation of the agricultural water-saving measures and continuous improvement of the level of water-saving,the effectiveness of agricultural water conservation has been obtained and the implementation level of agricultural water-saving measures is getting higher and higher,and greater potential leaves for further exploitation in the basin. |
