摘要
20世纪50年代初至70年代中期,我国荒漠化土地面积年均扩大1560平方公里,年均增长率为1.01%,70年代中期到80年代中期,年均扩大面积2100平方公里,年均增长率为1.47%.当前我国荒漠化土地面积正以每年2460平方公里的速度扩展,而且还有加速扩大的趋势.其中,尤以西部地区为烈.因此,我国西部地区荒漠化治理的现实路径的选择成为关键.
From 1950's to 1970's Chinese desertation land area increased 1560 square kilometers per year and the average increase rate is 1.01%. During the following 10 years the number became respectively 2100 and 1.47%. Nowadays, the expanding desertation area is 2460 square kilometers per year and most of them take place in Western China. Consequently, desertation control in that region becomes critical for the whole country.
