河西走廊灌溉农业发展的水资源承载能力分析

论文采用模糊综合评判方法,对河西走廊灌溉农业发展的水资源承载能力进行了分析,建立了评价的数学模型。研究表明,该区水资源开发利用已近于其饱和容量,发展节水灌溉,充分提高水的利用效率,是保障和发展干旱区农业的根本出路。

A study on water resource s carrying capacity for irrigation agricul tural development in arid area-a case study of Hexi Corridor

The scale of agricultural development of the arid area depends on the carrying ca-pacity of water resources,Taking Hexi Corridor as an example,this paper sets up an evaluation model by applying the fuzzy synthetic evaluation method.The results showed that the develop-ment of water resources in Hexi Corridor tended to reach saturation capacity.Therefore,to de-velop water-saving irrigation,raise utilization factor of canal system and improve water use effi-ciency are the fundamental way out for assuring and developing agriculture in arid area.
