摘要
荒漠化的驱动因素来自于两个方面:自然因素和人为因素。其中不利的自然因素是其发生发展的基础条件;不合理的土地利用、人口的迅速增长和政策上的失误等人为因素是造成我国荒漠化的主要原因,其主要表现形式是滥垦、滥牧、滥樵采、滥用水资源和滥开矿等。在此基础上本文简要介绍了我国荒漠化的现状及其发展趋势。由于造成荒漠化最重要的因素之一就是土地的不合理利用,因此合理的土地利用规划及其与之相应的环境影响评价就显得十分必要。土地利用规划环境影响评价对于防治沙漠化具有许多积极的作用,可以最大限度地防止荒漠化的出现。
The driving factors for development of desertification have two aspects： natural factors and artificial factors. Of these the adverse natural factors are the basic background condition for development of desertification, while the artificial factors including unreasonable land use, fast increasing of population and false policies, such as over-reclamation, over- grazing, unrestricted cutting, squandered water resources and indiscriminate mining, are the main causes of rapid wide-spreading of desertification in China. Based on that stated above, this paper briefly introduced the present status and developing trend of desertification in China. Because unreasonable land use is the main factor for development of desertification, the rational land use planning and the environmental impact assessment in it are important. Environmental impact assessment in land use planning has many positive effects, so it can prevent the development of desertification to maximal degree.
