摘要:目前我国水资源供需矛盾突出,水资源短缺对农业生产的限制日趋严重,调整农户灌溉技术的使用和提高灌溉用水效率有助于缓解我国农业用水压力。本文以河北省张家口市沽源县239份农户调查为样本,利用结构方程模型分析农户对节水灌溉技术认知的影响因素。结果表明:农户受教育程度、承受风险能力、灌溉成本、农业收入以及政府政策宣传都对农户节水灌溉技术认知有不同程度的影响,其中政府政策宣传影响最明显。因此,政府加强对节水灌溉技术的扶持力度和宣传力度,不断完善节水灌溉的推广体系,有助于提高农户节水灌溉的认知程度,提高农户积极性。29805

Based on the structural equation modeling of cognitive farmers water-saving irrigation technology and the main influence factors analysis
Abstract :At present,our country faces a serious problem which is the imbalance between supply and demand of water resource, the increasingly shortage of water resource severe restrictions on agricultural production. Adjust the use of farmers' irrigation technology and improve the efficiency of irrigation water is critical. The survey of 239 farmers in HeBei ZhangJiakou Guyuan county, using the structural equation modeling to analyze the factors of farmers cognition of water-saving irrigation technology. It is found that farmers' education degree,risk tolerance,irrigation costs,agricultural income and government policy ,all of these factors have different degrees of influence on farmers cognition, including government policies affect the most obvious. Government need to strengthen the support of water-saving irrigation technology and publicity.Also need to improve the promotion of water-saving irrigation system and improve the level of water-saving irrigation for farmers, improve the farmers' enthusiasm.
