- 摘要:
- 风沙危害是目前北京地区面临的最为严重的生态环境问题之一，搞好本区的生态修复工作具有重要的意义。以延庆县为例，系统分析了本区风沙化土地生态建设的制约因素以及生态修复现状中存在的问题，提出了今后生态修复的模式和4条对策：一是加强农田耕作制度的指导与管理；二是坚持生态修复与经济发展相结合；三是依靠科技，强化管理，提高防沙治沙的技术含量；四是加强法制建设，实行依法治沙。
- Abstract:
- Sand damage is one of the most serious eco-environment problems in Beijing. So,it has great meaning to do well in ecological rehabilitation engineering. According to the restricted factors of eco-environment construction in Yanqing district and problems in it,model and four countermeasures of ecological rehabilitation are brought out:first is to strengthen guidance and management of cultivated system in farmland; the second is to insist on combining ecological rehabilitation with economic development; the third is to depend on science and technology,intensify management and enhance technical content of preventing and controlling sands; the last one is to strengthen legal system construction,depending on law to control sands.
