    2020~2021年中国黄河流域沙化土地治理发展报告

    摘要

    黄河流域分布着大面积的沙化土地,主要位于黄河源高寒沙化土地区、上游干旱半干旱典型沙漠化区和下游黄河故道土地沙化区。20世纪90年代以来,随着防沙治沙力度的不断加大,黄河流域土地沙化程度明显减轻、沙化土地面积显著降低,但局部零星沙地仍存在扩大现象。黄河流域人民在防沙治沙实践中形成一批行之有效的实用技术和模式。针对沙化土地治理存在的问题和挑战,本报告提出了坚持科学治沙、防治草场退化、促进沙产业高质量发展等建议。

    Abstract

    The Yellow River Basin with a large area of desertified land,is mainly located in the alpine desertified land area at the source of the Yellow River,the typical arid and semi-arid desertification area at the upstream and the desertified land in the old channel of the lower Yellow River at the downstream. Since the 1990s,with the increasing efforts of sand prevention and control,the degree and area of desertified land in the Yellow River Basin have been significantly reduced,but the expansion of local sporadic desertified land still exists. The people of the Yellow River Basin have also formed a number of effective and practical technologies and models in the practice of sand prevention and control. In response to the problems and challenges in the control of desertified land,the report puts forward some suggestions on adhering to scientific desertification control,preventing grassland degradation and promoting the high-quality development of desertification industry.
