林业非点源污染研究进展

Progress of research on non-point source pollution of forestry

非点源污染作为目前影响水环境质量的重要污染源,已引起广泛关注,并成为研究热点之一,但其研究重点主要集中在农业非点源污染领域。而林业非点源污染对山区、丘陵等区域地表水体的水质有重要的影响,尤其是采伐、整地、使用化学物质和林火等林业活动对水质的影响更大,因此开展林业非点源污染的研究,制定相应的防治措施具有重要的意义。

Non-point source pollution is an important pollution of water environment quality which has been given extensive attention and become a hot research topic,but the research is mainly focus on the field of agricultural non-point source pollution.Non-point source pollution from forestry has important impact on the quality of surface water bodies of mountain area,hilly land and other regions.In particular,the management activities such as cutting,soil preparation,use of chemical substances and prescribed burning have greater impact on the water quality.Therefore,carrying out research on forestry non-point source pollution and taking relevant prevention measures will be of great significance.
