| 为了讨论方法集模型对于灌区用水效率综合评价的可行性，以DEA模型作为对比参照，选取了渠系和田间两方面指标，对黑龙江省20个灌区用水效率进行排序和计算，得出的主要结论：利用方法集模型评价的20个灌区的排序结果均通过Spearman检验，解决了不同评价方法结果不一致的问题，且与DEA模型得出的排序结果一致；通过方法集模型和DEA模型结果可以看出：富裕、永发、安邦河、龙头桥和石龙灌区效率值较低，分别是0.58、0.55、0.54、0.51、0.45，且20个灌区灌溉用水效率与渠系效率平均关联度为1.779，与田间效率平均关联度为1.229，受渠系水利用效率影响较大，受田间水效率影响较小，可采取渠道衬砌，合理规划渠系布局等方式减少渠道输配水环节的灌溉水损失，采取控制灌溉技术，喷、滴灌溉等节水措施，提高灌溉用水效率。 |

| In order to comprehensively and scientifically evaluate the utilization of agricultural irrigation water in irrigation areas, using DEA model as a comparative reference, two indicators, canal system, and field, were selected to rank and calculate the water use efficiency in 20 irrigation areas in Heilongjiang Province. The main conclusions were as follows: The sequencing results of 20 irrigation districts evaluated by the method set model were all tested by Spearman test, which solved the problem of inconsistent results of different evaluation methods and was consistent with the sequencing results obtained by DEA model. The results of method set model showed that the efficiency values of Fuyu, Yongfa, Anbang River, Longtou Bridge, and Shilong irrigation districts were lower and their efficiency values were 0.58, 0.55, 0.54, 0.51, and 0.45. The average correlation between irrigation water use efficiency and canal system efficiency was 1.779, and the average correlation between irrigation water use efficiency and field efficiency was 1.229, which was greatly affected by the water use efficiency of canal system, but the field water efficiency was less affected. In order to reduce the loss of irrigation water in the water supply and distribution links of canals, measures such as lining of canals, rational planning of canal system layout and water saving measures such as controlling irrigation technology, spraying and dripping irrigation can be adopted to improve the efficiency of irrigation water use. |
