芜湖市农户废旧地膜捡拾的影响因素研究

Research on the Influencing Factors of Waste Mulching Plastic Film Collection in Wuhu City

为使芜湖市地膜残留污染问题得到有效解决,应用二元Logistic回归模型对农户残膜捡拾程度的影响因素进行研究。结果表明80.45%的农户捡拾残膜,其中33.83%只捡拾地表残膜,46.62%先清理地表残膜,翻耕时再次捡拾。农户年龄、家庭成员最高文化程度、2018年家庭非农收入、对残膜危害的了解程度、对可降解地膜的了解程度对农户残膜捡拾程度有显著正向作用;健康状况、主要从事的工作、覆膜面积和所在村或乡镇是否有地膜回收站点对农户残膜捡拾程度有显著负向作用;户主文化程度、参加技术培训频次、回收废品情况、耕地面积、2018年种植纯收入、处理残膜的原因和对地膜节约技术的了解程度的影响不显著。

In order to effectively solve the problem of plastic film residue contamination in Wuhu City, the paper used binary Logistic regression model to study the factors affecting the recovery degree of plastic film residue. The results showed that 80.45% of the farmers picked up the residual membrane, of which 33.83% only picked up the surface residual membrane, and 46.62% cleaned the surface residual membrane first and picked it up again during tillage. The age of farmers, the highest educational level of family members, the household non-agricultural income in 2018, the understanding degree of residual film hazards, and the understanding degree of degradable plastic film had significant positive effects on the recovery degree of residual film. Health status, main work, mulching area and whether there is a plastic film recovery site in the village or town had significant negative effects on the recovery degree of residual film;the influence of household head’s education level, frequency of participating in technical training, recycling situation, cultivated land area, net planting income in 2018, reasons for disposing residual film and understanding degree of plastic film saving technology were not significant.
