【摘要】 在汶川8.0级地震及其次生灾害的共用作用下,地震灾区生态环境变得更加脆弱。灾后3年灾区重建任务主要集中在经济社会方面,对生态环境重建的投入不足,以及灾区高碳化产业结构,造成灾区生态系统功能退化,灾区生态系统出现弱均衡现象,严重影响灾区生态系统的可持续发展。灾区生态弱均衡可防可控,通过在灾区树立低碳均衡发展思想,制定灾区生态低碳发展路径;加大节能减排工作力度,调整灾区产业结构;推行退耕还林政策,发展林木产业,推进生态农业低碳建设;构建森林碳汇示范基地,实施低碳生态战略,推动灾区生态系统全面可持续发展。更多还原

【Abstract】 Under the coaction of Wenchuan M8.0 earthquake and its secondery hazards,ecological environment of the earthquake-stricken area become more vulnerable.During the three years after the eartquake,reconstruction focused mainly on economic and social aspects,investment to the reconstruction of the ecological environment is insufficient,togethe with the high-carbon structure of industries in the area,and the ecological system of the earthquake-stricken area falls to functional deterioration and weak equilibrium,which influences the sustainable development of the ecological system greatly in the area.The weak equilibrium is preventable and controllable however.To promote comprehensive and sustainable development of ecosystems,several measures of low-carbon model are presented as follows: establishing equilibrium development thinking,making a ecological low-carbon development path,increasing energy conservation efforts,adjusting the industrial structure,practising the policy of reverting cultivated land to forests,developing forest industry,promoting low-carbon eco-agriculture construction,onstructing forest carbon sequestration demonstration bases,implementating the ecological low-carbon strategy,and promoting the comprehensive development of ecological system in the area.更多还原
