华北地下水超采区农户节水灌溉技术认知分析——以河北省张家口市沽源县为例

目前我国华北地区面临严重的地下水超采问题,在地下水超采综合治理行动方案中明确提出要加强农业节水,调整农业种植结构。农户节水灌溉技术认知与农业节水效果密不可分,本文以河北省张家口市沽源县269份农户调查为样本,采用结构方程模型探索农户节水灌溉技术认知的内在机理。结果显示：农户个人特征、家庭生产特征、政策宣传特征和农户水资源稀缺性认知的路径系数分别为0.186、0.157、0.469和0.200。表明节水灌溉技术补助、培训和参观高效节水示范区对提升农户节水灌溉技术认知的效果显著。因此,在依靠政府技术资金支持的基础上,发现农户节水灌溉技术认知差异,制定完善的节水灌溉技术宣传推广体系,有利于提高华北地区农户采用节水灌溉技术的积极性。

Farmer cognition on water-saving irrigation technology analysis in groundwater overmining area of North China: A case study of Guyuan county,Zhangjiakou city,Hebei province

At present, North China faces serious groundwater overmining problem. In the action plan of comprehensive control of groundwater overmining in North China, it is clearly proposed to strengthen agricultural water saving, and adjust the structure of agricultural planting. Farmers' cognition of water saving irrigation technology is closely related to water saving effect. This paper takes the survey of 269 farmers in Guyuan county, Zhangjiakou city, Hebei province as a sample, uses structural equation model to explore intrinsic mechanism of farmers' cognition of water saving irrigation technology. Results show that, the path of personal characteristics of farmers, characteristics of household production, characteristics of policy advocacy, farmer cognition of water resources scarcity are 0.186, 0.157, 0.469 and 0.200. respectively. It is indicated that water saving irrigation technology subsidy, technical training and visiting high efficiency water saving demonstration area are effective in improving farmers' cognition of water saving irrigation technology. Therefore, on the basis of reliance on government technical financial support, we should find out the farmers' cognition differences in water saving irrigation techniques, and perfect the publicity system of water saving irrigation technology so as to enhance farmers' enthusiasm to use water saving irrigation technology in North China.
