浑善达克沙地沙漠化成因及其综合防治

Causes and Comprehensive Control Measures of Desertification in Hunshandake Sand Land

浑善达克沙地是我国的4大沙地之一,也是气候变化及人类活动影响较为敏感的地区之一。20世纪60年代以后,该沙地发生了严重的沙漠化,不仅恶化了当地的生态环境,制约了区域经济的发展,而且成为京津地区最主要的沙尘源之一,对京津、华北等周边地区人民的生产、生活和生态安全构成了愈来愈严重的威胁。在搜集资料、进行野外考察和调查的基础上,着重分析了造成本区沙漠化发生发展的各种因素,并结合当地实际提出沙漠化防治的基本措施和对策。

Hunshandake sand land is one of the four main sand land and one of places which are sensitive to the change of climate and human activity impact. After1960's,Hunshandake sand land has seversly desertified, which has not only deteriorated the local eco-environment, restricted the development of territorial economy, but also become into one of the main source of sand and dust in Jingjin region, threatened ecological security, people's production and life around Jingjin and north China more and more.
