广西沙田镇农村农户生态足迹及其影响因子分析

Household ecological footprint and its infleuncing factors: a case study in Shatian Town,Guangxi Zhuang Autonomous Region

为研究我国南方农村家庭生态足迹及其与农业生产生活和能源消耗之间的关系,对广西贺州市平桂管理区沙田镇51户农户的能源消耗和家庭生产情况进行实地调查,采用生态足迹分析方法和多元线性回归模型对调查数据进行分析计算,结果表明沙田镇的农户经济以农业生产为主,农业生产生态足迹是农户生态足迹的主要构成部分,其中化肥、农药的生态足迹比重最大,农业产量和家庭耕地面积对农村家庭生态足迹起主要决定作用。为了减少农户生态足迹,需要提高化肥、农药的使用效率,调整农业生产结构、转变生产方式和消费模式,提高单位面积土地的生物产量和土地资源利用效率。

In order to investigate the ecological footprint of household in rural area of Guangxi and the relationship among the ecological footprint,agricultural production and living and farmers＇ energy consumption,51 farmer families＇ corresponding satuations in Shatian Town of Hezhou City in Guangxi were surveyed.Base on the data collected from the survey of 51 farmer families,a multiple linear regression model was established to analyze the ecological footprint.The results show that farmers economy mainly consisted of agricultural production,which contributed to a large components of household ecological footprint.Within agricultural production,fertilizer and pesticides application were the largest proportion of ecological footprint.The productivity of agricultural and agricultural production area of rural familes played a decisive role in household ecological footprint.Therefore,several strategies to reduce household ecological footprint in rural area were put forward,including the increase of fertilizer and pesticides use and efficiency,the adjustment of production structure,the changes in production mode and consumption pattern,and the increase of productivity per unit area and land use efficiency.
