| Popis: | The study built Albedo-NDVI feature space model by using Landsat TM remote sensing image during 2007-2013, analyzed desertification situation of Acukeerqin Banner. The results showed that: these years, Mild desertification area of study area increased from 466.73 hm2 to 495.96 hm2, increased by 29.23 hm2. By 2013, the slight desertification area reached 591.82 hm2, have accounted 40.2% of whole area. During the study period, the moderate desertification area increased from 316.06 hm2 to 345.16 hm2, increased by 29.1 hm2, but the servere desertification land area decreased 43.82 hm2. It is shown that the land desertification problem has improved, overall has a good trend, severe desertification has slowed down under the management of preventive measures, as it change into moderate or mild desertification interval. The main causes of desertification in the study area are the excessive reclamation, population growth, reduction of rainfall and temperature rise. |
