贵州省农田地膜残留现状及污染防治对策OACSTPCD
Status of Farmland Plastic Film Residue and Pollution Control Countermeasures in Guizhou Province
随着地膜使用年限的不断增加,农田地膜大量残留造成的"白色污染"不但严重影响农田土壤质量和农业生产,同时也对农村生态环境安全构成巨大的威胁.本研究通过中国农村统计年鉴和调查点,分析了2001-2021年地膜使用量和覆膜面积的变化特征,2019-2022年省调查点地膜的残留现状及回收情况,并提出增强农民环保意识,建设地膜回收利用体系,强化监测评价,完善地膜残留监测网络等防治对策,研究结果为贵州省农田地膜的科学使用和回收利用提供了数据支撑,为残留污染的防控提供了参考依据,促进了农业绿色高质量发展.
With the increasing years of plastic mulch usage,the"white pollution"caused by its massive residues has significantly deteriorated farmland soil quality and agricultural production,posing a substantial threat to rural ecological safety.This study analyzes the changing trends of plastic mulch usage and covered area from 2001-2021,and the status and recycling of mulch residues from 2019-2022 based on data from China's Rural Statistical Yearbook and fixed-point monitoring.It suggests enhancing farmers'environmental awareness,establishing a mulch recycling system,strengthening monitoring and evaluation,and improving the mulch residue monitoring network.The findings provide data support for the scientific use and recycling of farmland plastic mulch in Guizhou Province and serve as a reference for residue pollution control,fostering high-quality green agricultural development.
