中国是受荒漠化危害最为严重的国家,荒漠化对社会、经济及人们的生存环境造成了严重的危害。1999年完成的第二次全国荒漠化监测结果显示,目前我国荒漠化仍呈扩展趋势。近两年来,日趋严重的沙尘天气,不仅给北方干旱地区也给东部地区的人民群众带来了严重危害,沙尘天气的加剧从一个侧面反映出目前我国荒漠化的严重形势。 China is the country most seriously affected by desertification, and desertification has caused serious harm to society, economy, and people’s living environment. The results of the second national desertification monitoring completed in 1999 showed that desertification in China is still expanding. In the past two years, the increasingly serious dust weather has not only brought severe damage to the arid regions in the north but also to the people in the eastern region. The intensification of dust weather reflects the serious situation of desertification in China at present.
