摘要
松花江三湖流域是吉林省水资源和林业基地,是长白山动植物资源保护的重要地域.通过对三湖流域土地利用变化及其对生态环境的影响的深入剖析发现,随着人口的增加和经济的发展,三湖流域土地利用结构发生了显著变化,并导致了土地资源生态环境背景的变化,生态环境质量下降甚至恶化,严重影响了水资源、森林资源的可持续利用.并对三湖流域土地利用变化的生态环境效应进行研究,为改变人们的生产方式,加强对资源与环境的保护,促进区域经济与环境的协调发展奠定了基础.
The 3-lakes of the Songhua River is the base of water resources and forestry in Jilin province,and the important region for protecting the animal and plant resources of the Changbai Mountains.With the increase of population and the development of economy,the land use change in 3-lakes is more notable,cause the change of environmental background of land resources and make the ecoenvironmental quality come down,so as to influence seriously the sustainable utilization of water and forest resources.Studying the effect of land use change on ecoenvironment in 3-lakes can make people change the production fashion,notice the protection of resources and environment,and make the regional economy and ecoenvironment develop in a good way.
