采用多点监测的方法,研究了攀西地区地膜残留量及影响因素.结果表明,攀西地区平均地膜残留量为16.27 kg·hm-2,90％以上残留在耕作层,残留量显著低于新疆等北方地区；机械化耕作加大了地膜残留,人工耕作减少了地膜残留；覆膜前10年是地膜残留累积的主要时期,覆膜10年后地膜残留量相对稳定,耕作层以下地膜残留程线性累积的过程；生育期短和栽培管理复杂的蔬菜等作物加大了地膜残留.%The plastic film residues and influence factors in Panxi District of Sichuan Province were studied by multiple spot monitoring. The results showed that the amount of plastic film residues in Panxi district was 16.27 kg·hm-2, and 90 % of plastic film residues was distributed in cultivated horizon. The amount of plastic film residues was notablely lower than that of Xinjiang province. The first decennary was the period of plastic film residues cumulating in field and film residues amount was stable in ten years after plastic film mulched,but the plastic film residues amount under cultivated horizon was higher and higher along mulching years. The plastic film residues amount was increased by the short life crops adoption, such as vegetables.
