甘肃沙漠化及沙漠化治理
中文摘要
在环境污染日益严重的今天,环保问题越来越受到更多人的关注。柴静的《穹顶之下》把人们的目光集中在了大气污染上,但环境污染不仅只有大气污染,尤其在陇原大地上,有着比大气污染更为严重和紧迫的任务——土地沙漠化。土地沙漠化吞噬土地和水资源,形成沙漠,压缩着人们的生存空间,严重制约甘肃经济的发展。而且,沙漠中的沙尘经常随风光顾全省各地,影响人们的生产生活和身体健康。一直以来,政府每年为治理沙化和发展沙产业投入数百万的资金,沙化有了一定的改观,但整体仍然不容乐观。沙漠化已经成为了甘肃挥之不去的痼疾。本论文通过深入甘肃沙化影响最为严重的民勤地区,了解沙漠的形成及治理,调查沙化对周围居民生活的影响,投入沙产业实践劳动,对甘肃沙漠化程度以及沙漠化治理成果等进行了详细分析。
