摘要
第六次全国荒漠化和沙化调查以第三次全国国土调查成果为底板,以2019年为基准年,全面查清了我国荒漠化和沙化的状况。通过简要介绍第六次全国荒漠化和沙化调查的基本情况,全国荒漠化和沙化土地状况和动态变化,结合相关资料分析了目前的防治形势并提出了对策建议。调查结果显示,截至2019年,我国荒漠化土地面积为25737.13万hm^(2),沙化土地面积为16878.23万hm^(2)。与2014年相比,5年间全国荒漠化土地面积净减少378.80万hm^(2),年均减少75.76万hm^(2)。沙化土地面积净减少333.52万hm^(2),年均减少66.70万hm^(2)。
The Sixth National Survey on Desertification and Sandification was based on the results of the Third National Land Survey,using 2019 as the benchmark year.The results showed a comprehensive status of desertification and sandification in China.This paper presented a brief overview of this survey,the status and dynamic changes of desertification and sandification in China,conducted a comprehensive analysis of the current situation,and proposed some suggestions for combating desertification and sandification.The survey results showed that,until 2019,the desertification land area in China was 257.3713 million hm^(2) and the sandification land area was 168.7823 million hm^(2).Compared with 2014,the desertification area of China decreased by 3.7880 million hm^(2) with an average annual decrease of 757.6 thousand hm^(2).The sandification area of China decreased by 3.3352 million hm^(2) with an average annual net reduction of 667 thousand hm^(2).
