荒漠化

非洲有三分之一的土地面临荒漠化的威胁。

A third of Africa is under threat of desertification .

开展国土绿化行动，推进荒漠化、石漠化、水土流失综合治理，强化湿地保护和恢复，加强地质灾害防治。

We will promote afforestation , take comprehensive steps to control desertification , stony deserts , and soil erosion , strengthen wetland conservation and restoration , and better prevent and control geological disasters .

第三十八条国家鼓励单位和个人按照土地利用总体规划，在保护和改善生态环境、防止水土流失和土地荒漠化的前提下，开发未利用的土地；

Article 38 The State encourages development of unused land by units or individuals according to the general plans for the utilization of land and under the precondition of protecting and improving the ecological environment , preventing water loss , soil erosion and desertification .

通过对图像几何和投影系统转换，图像标准假彩色合成，影像空间增强处理，并结合划分的土地利用/覆被类型，建立TM影像目视解译标志，进行荒漠化信息的提取。

Through geometrical and projection system transform , standard false color composite , spatial enhance to image , link with land use / cover type , establish interpret symbol of TM image , and to extract information of desertification .

根据2001年8月31日Landsat卫星遥感TM数据，结合现场调查，通过景观熵值、植被覆盖度等指标综合评判，对研究样地荒漠化程度进行划分。

According to Landsat remote sensing TM statistics on August 31 ~ ( th ), 2001 , together with the local investigation , the desertification level was classified through evaluation of the entropy and vegetation coverage , etc.

结果表明：黄河源区近15a来高覆盖度草地、湿地和冰川面积急剧减少，未利用土地面积增加，土地荒漠化程度加剧，土地利用综合程度指数下降。

The results show that the area with a high coverage of grassland , wetland and glacier decreased in the time period , while the area of barren land increased . The comprehensive land use index decreased remarkably , indicating that desertification worsened .
