土地利用规划实施后吉林省环境变化评价

Assessment of Environmental Change After the Implementation of Land Use Plan in Jilin Province

基于生态足迹理论及其技术方法,进行吉林省土地利用总体规划(2006-2020年)环境影响评价的实例研究。结果表明,1996-2005年吉林省生产型生态赤字逐年增加,规划期内的生态恢复与建设任务比较艰巨;2010年吉林省生态赤字与规划基期(2005年)相比,有了相大幅度的减少,但受人口总量影响,土地生态承载力持续降低;2020年受消费水平,尤其是能源消费影响,吉林省生态赤字反弹,但仍优于规划基期;综上所述,吉林省规划期内土地利用结构和规模调整方案,有利于减轻土地生态压力,提高吉林省生态环境质量水平和土地生态承载力,实现土地利用与生态环境建设协调发展。

The strategical environmental assessment on land - use planning of Jilin province is studied based on ecologi- cal footprint theory and methods. The result shows the ecological deficit is increasing from 1996 to 2005 year in Jilin province, which means the task ecological rebuilding is arduous in stage of land - use planning. While the ecological defi- cit will have large decreasing in 2010 by comparing the year of 2005 ,the capacity of land ecological system will continu- ous reduce because of the big population. Because the level of consume, especially energy consume will have been im- proved, the ecological deficit will deteriorate in 2020. And the ecological deficit is in 2020 less than the year of 2005. The programme of land use is helpful for reducing the pressure of land ecological capacity,improving eco - environmental level, and promoting the coordinate development of land use and eco - environmental construct.
