基于AquaCrop作物-水生产力模型,综合分析研究了影响江苏省农业用水效率的影响因素。在此基础上,利用模型模拟结果,估算了不同作物在变化的环境条件下的净灌溉需求和作物需水量。最后,根据多因素回归模型计算各环境要素对农业用水效率的影响大小。研究结果发现,平均湿度、总灌溉面积、滴灌面积、施肥率、土壤表面优良率是最需要注意的五项影响因素。通过关键影响因素分析可知,改善农业用水效率需要加强农田水利设施建设、减少土壤侵蚀和水资源污染、推行田间节水灌溉技术。同时,为保证农业用水的高效使用,在生长季节提供的灌溉用水量不得超过作物的有效用水需求。

Based on the AquaCrop crop-water productivity model, this article comprehensively analyzed the factors affecting agricultural water efficiency in Jiangsu Province. On this basis, using model simulation results, the net irrigation requirements and crop water requirements of different crops under changing environmental conditions were estimated. At last, according to the multi-factor regression model, the impact of various environmental factors on the efficiency of agricultural water use was calculated. The results of the study found that the average humidity, total irrigated area, drip irrigation area, fertilization rate, and soil surface goodness rate were the five most important factors. Through the analysis of key influencing factors, we can see that improving agricultural water efficiency requires strengthening the construction of farmland water conservancy facilities, reducing soil erosion and water pollution, and implementing field water-saving irrigation technologies. Meanwhile, in order to ensure the efficient use of agricultural water, the amount of irrigation water provided during the growing season must not exceed the effective water demand of the crop.
