土地荒漠化不仅是一个重大的生态环境问题,也是我国社会经济可持续发展所面临的非常严峻的问题。我国荒漠化土地面积约为262.2万km~2,占国土面积的27.3%。当前荒漠化土地面积正以每年2460km~2的速度扩展,而且还有加速扩大的趋势。我国在建国初期就开展荒漠化的治理,近半个世纪以来,荒漠化研究治理工作已经取得了一些令世人惊叹的成就,但荒漠化点上治理、面上破坏,局部好转、总体恶化的局面,仍未得到根本改观,荒漠化的治理亟待模式上的创新。荒漠化的生产虽然是从植被破坏产生土
Land desertification is not only a major ecological and environmental issue, but also a very serious issue that our country faces in its sustainable social and economic development. The area of desertified land in China is about 2,622,000 km 2, accounting for 27.3% of the total land area. At present, the area of desertified land is expanding at a speed of 2,460km ~ 2 per year, and there is a trend of accelerating its expansion. Since the founding of our nation, desertification control has been carried out in the early days of the founding of New China. Since the past half century, desertification research and management work has made some amazing achievements. However, the desertification control, destruction, partial improvement and overall deterioration have not yet been achieved It has been fundamentally changed that desertification governance is urgently needed to be modeled on innovation. Although the production of desertification is the soil from the destruction of vegetation
