摘要：全球沙漠化问题导致人类的生存空间和可持续发展已经受到了严重的威胁,成为全世界关注的重要生态环境问题。中国是世界上沙漠化危害最严重的国家之一。中国政府对此非常重视,并在几十年的沙漠化防治工作中取得很大的成就。从20世纪70年代后期以来,先后启动了如“三北”防护林、治沙工程、退耕还林还草等重点生态建设工程,取得了一定成绩。但是中国目前仍面临着“局部逆转、总体恶化”的严峻形势。展望未来沙漠化的防治,应在已有成绩之上,改变思路,将生态效益与经济效益有效结合,以人为本,以防为主,科学防沙治沙。

Abstract: Global desertification, which has been a serious threat to human survival environment and sustainable development, is the most important eco-environmental problem in the world. China is one of most serious desertification countries in the world. China has paid great attention and high regards to the prevention and control of desertification. Great and productive achievements have been obtained in the past decades. Since the late 1970s, the government has started series of program such as the“Three North”Windbreak System, Control Desertification Project, Recovery of Forest and Grassland from Farmland and other key ecological construction projects. Obvious successes have been achieved. But desertification control in China at present is still faced with an arduous status of“locally reversed but wholly worsen”. Looking ahead, the future desertification prevention and control should be aimed to integrate ecological and economic benefits effectively, undertake people-oriented approach, pay priority attention to prevention of desertification, and utilize more scientific strategies.
