摘要

In order to study current situation of application,recycling and residue pollution of mulching films in Xinjiang,and accurately grasp pollution degree of residue of mulching films,this paper made an empirical analysis on residue of mulching films in 31 typical counties and cities in Xinjiang. Results indicate that( i) use of mulching films in Xinjiang is wide and there is great difference in use and residue recycling between cities and counties. Planting area and planting structure jointly influence use of mulching films,and the use of mulching films is significantly correlated with recycling of mulching films,but not correlated with recycling rate of mulching films.( ii) There are significant differences in distribution of residue of mulching films,highest in North Xinjiang and South Xinjiang,followed by East Xinjiang,and the lowest in West Xinjiang.( iii) There are significant differences in distribution of residue of mulching films between different crop fields. Residue of mulching films in cotton field is the key problem of pollution.
