摘　　要：干旱半干旱地区缺乏针对性的灌溉水源适宜性评价方法,且评价方法适用性不强,指标较为单一,无法运用至多种水源,故以干旱半干旱地区为研究对象,探究能适用于不同灌溉水源适宜性的评价方法。综合考虑灌溉水源可供应量、灌溉水供应及时程度、提水能耗费、灌溉水温等因素构建灌溉水源适宜性评价指标体系,引入群体决策熵优法-CRITIC算法确定评价指标的组合权重,以宁夏平罗县3种可利用的灌溉水源为典型案例,结合构建的评价指标体系及权重确定方法,采用TOPSIS法对3种不同水源4-9月的灌溉适宜性进行综合评价。平罗县黄河水与排水4-9月的贴近程度值皆大于0.31,均适宜灌溉。地下水4月的贴近程度值仅为0.2412,不适宜灌溉,但地下水5-8月的贴近程度值皆大于0.31,适宜灌溉,与宁夏银北灌区实际情况相符。构建的评价指标体系和引入的组合权重确定方法(群体决策熵优化-CRITIC算法)适用于干旱半干旱区的灌溉水源适宜性评价。There is a lack of targeted evaluation methods for the suitability of irrigation water sources in arid and semi-arid areas.Existing evaluation methods tend to have limited applicability and rely on single indicators,which restricts their usefulness across different water sources.Therefore,this paper takes arid and semi-arid areas as the research object to explore the evaluation methods that can be applied to the suitability of different irrigation water sources.The suitability evaluation index system of irrigation water source was constructed by comprehensively considering factors such as the available supply of irrigation water source,the timeliness of irrigation water supply,the consumption of water lifting energy,and the irrigation water temperature.The group decision entropy optimization method algorithm was introduced to determine the combined weight of the evaluation index.Taking three available irrigation water sources in Pingluo County of Ningxia as a typical case,the TOPSIS method was used to comprehensively evaluate the irrigation suitability of three different water sources from April to September,combined with the constructed evaluation index system and weight determination method.The closeness degree values of Yellow River water and drainage in Pingluo County from April to September were all greater than 0.31,suggesting their suitability for irrigation.The close degree value of groundwater in April is only 0.2412,which is not suitable for irrigation.Still,the closeness degree value of groundwater from May to August exceeds 0.31,which is suitable for irrigation,and is consistent with the actual situation of Yinbei Irrigation District in Ningxia.The evaluation index system constructed in this paper and the introduced combination weight determination method(group decision entropy optimization-CRITIC algorithm)are suitable for the suitability evaluation of irrigation water sources in arid and semi-arid areas.
