摘要:

岩溶地区第四次石漠化调查以第三次全国国土调查成果为底版,以2021年为基准年,全面查清了我国石漠化土地状况及变化。通过简要介绍第四次石漠化调查基本情况、石漠化土地现状及动态变化状况,分析目前的石漠化防治形势,提出防治对策建议。调查结果显示,截至2021年底,我国石漠化土地面积722.3万hm2,与2016年同口径相比,石漠化土地面积净减少333.1万hm2,年均减少66.6万hm2,表明我国石漠化土地总体向“面积减少、程度减轻、生态状况稳定向好”的方向转变。

关键词: 岩溶地区, 石漠化, 状况, 动态变化

Abstract:

The fourth rocky desertification survey in Karst area was based on the result of the third national land survey,while taking 2021 as the base year to comprehensively investigate the condition and change of the rocky desertification land China.This paper briefly introduced the basic situation of the fourth rocky desertification survey,the present situation and dynamic change of rocky desertification land,as well as analyzed the current situation of rocky desertification control,and put forward countermeasures and suggestions.The results showed that,the rocky desertification land area was 7.223 million hm2 by 2021.Compared with 2016,the net decrease of rocky desertification land area was 3.331 million hm2,while the average annual decrease was 0.666 million hm2.The main results indicating that the rocky desertification land in China presents the overall evolution direction of "area decreasing,degree reduction and ecological condition being stable ".

Key words: karst area, rocky desertification, status, dynamic change
