摘 要:我国水资源紧缺且分布不均衡,无法满足农业生产用水的需求,所以在农业灌溉中引入节水灌溉技术非常迫切,水是蔬菜生长过程中不可缺少的重要因素,传统蔬菜种植过程中,水资源浪费严重,引入节水灌溉技术可以降低蔬菜作物的耗水量,同时提高产量,大幅提高蔬菜种植经济效益。通过对郑州周边中牟县、毛庄镇、惠济区蔬菜种植基地走访调查,确定了影响蔬菜种植户选择节水灌溉技术的因素,随后运用逻辑回归模型对影响因素进行了分析,并从发展规模化种植、增加节水灌溉补贴、加大宣传培训三方面提出了相应的对策和建议。

Abstract: Shortage and uneven distribution of water resource in China, unable to meet the needs of agricultural production water, so the introduction of water-saving irrigation technology in agricultural irrigation is very urgent, water is an important and indispensable factor in the process of vegetable growth, in the process of the traditional vegetable, water waste is serious, the introduction of water-saving irrigation technology can reduce the water consumption of vegetable crops, increase production at the same time, significantly improve the economic benefits of vegetable planting. Based on the investigation of vegetable planting bases in Zhongmou County, Maozhuang Town and Huiji District around Zhengzhou, this paper determined the factors affecting vegetable farmers' choice of water-saving irrigation technology, and then analyzed the influencing factors by Logistic regression model. Corresponding policy suggestions were put forward from three aspects of developing large-scale planting, increasing water-saving irrigation subsidy and increasing publicity and training.
Key words: vegetable planting; water saving; empirical analysis
水是生命之源,是地球上動植物生存不可或缺的重要条件。同时,水资源还与经济和社会的发展息息相关,水资源短缺会大大制约一个国家和地区的经济发展,随着全球气候的变暖,以及经济快速发展带来的人口爆炸等问题,水资源短缺的问题日益严重[1]。面对如此紧缺的水资源现状,如何更好的保护水资源节约利用水资源,成为了当前社会研究的重要方向。据不完全统计,我国淡水资源的总储量仅为2.8万亿m3,约占全球淡水资源总储量的6%,人均淡水资源占有量仅为全球平均水平的1/4,是世界最缺水的国家之一[2]。农业是水资源的使用大户,据统计,中国淡水资源消耗中有超过60%被用在农业灌溉上。受“大水漫灌才能浇透土地”等落后思想的影响,中国农业用水效率极低,平均利用系数仅为0.3,与发达地区的0.8的利用系数相比,有非常大的差距[3]。……
