卫星遥感技术在河北坝上土地沙化调查中的研究应用

Study and application on land desertification of the western flatland of Hebei province using satellite remote sensing technique

介绍了利用卫星遥感技术对坝上西部地区土地沙化的调查研究。对调查区的土地沙化现状及沙化成因进行了分析，提出了土地沙化治理对策。通过多时相对比研究，得出了坝上西部地区土地沙化总体向轻、缓方向微弱发展、局部加剧的结论。

The investigation on land desertification of the western flatland of Hebei province using remote sensing technique is introduced. The land desertification status and the cause of desertifica-tion is analyzed, and the countermeasure of harnessing land desertification is gaved in the paper. On the basis of multi -temporal comparative analysis, aconclusion is obtained, the change tendency of land desertification in the whole area is lighter and lighter, but the sitution Lang desertification in some area is getting worse.
