京津风沙源成因分析与防治对策研究

Analysis on the causes and strategies of desertifieation in Beijing and Tianjin

沙漠化是当今世界人类共同面临的一个重大环境及社会问题。早在1977年联合国内罗毕国际荒漠化会议就把北京列为荒漠化边缘化城市之一。日趋严重的沙尘暴，不仅影响京津的生态环境、社会环境，而且困扰现代城市及人们的生活方式，已到非治理不可的程度。然而，目前我们对京津风沙源地区的沙漠化现状、成因、扩展趋势及其如何防治还不十分清楚。因此，必须对京津风沙源地区的沙漠化现状及其成因进行全面分析，并对其荒漠化及其治理进行评价，在此基础上提出京津风沙源治理的应对策略。

Desertification is becoming a major environmental and social problem today. Increasingly severe dust storms, not only affect the ecological and social environment, but also disturbed the modern city and the people＇s way of life. So we have to control it. However, we don＇t know well about the sandstorm source areas of desertification status, causes, trends in Beijing and Tianjin, and how to expand prevention and treatment. Therefore, we need to comprehensive analyze sandstorm source status and causes of desertification in Beijing and Tianjin. Base on this , we will find a solution.
