摘  要：
选取湖北省4个典型区域作为研究对象,通过开展问卷调查和典型样点采集的方式,对湖北省地膜的使用与残留现状进行了分析。结果表明,湖北省4个典型区域覆膜比例为10%～88%,地膜厚度为0.005～0.014 mm,每年地膜使用量为17.29～50.16 kg/hm2,地膜使用量与覆膜比例有关,地膜使用后均不作回收;0～30 cm土层地膜残留量为10.72～38.20 kg/hm2,残留的地膜主要集中在0～20 cm土层中,该土层残膜量占0～30 cm土层残膜量的92%及以上;0～30 cm土层残留的地膜为18.83万～80.47万片/hm2,0～20 cm土层残膜数量占0～30 cm土层残膜数量的78%及以上;残留的地膜主要以中块膜(4～25 cm2)和大块膜(>25 cm2)为主,小块膜(<4 cm2)相对较少。

摘  要：
Through questionnaire survey and sample collection in representative regions of Hubei province(i.e.Hong′an County,Xishui County,Honghu City and Jiayu County),the mulching film application and residue status in soil layer(0～30 cm) were analyzed.The results showed that the plastic film mulching area accounted for 10%～88% in the investigated region.And the thickness of mulching film was 0.005～0.014 mm.The application amount of mulching film was 17.29～50.16 kg/hm2 every year and was related to the mulching proportion.The mulching film was not recycled in the four regions.The mulching film residue in surface soil(0～30 cm) was 10.72～38.20 kg/hm2 and was primarily concentrated in the plough layer(0～20 cm),contributed to more than 92% of the film residue in 0～30 cm soil.The quantity of residual film was 1.883×105～8.047×105 pieces per hectare and those in the plough layer was more than 78%.According to area of residual film,they were divided into three categories,i.e.large size(> 25 cm2),medium size(4～25 cm2) and small size(<4 cm2).The former two categories were the main size.
