- Abstract:
- Desertification is an important factor influencing the change of ecosystem service values. The desertification dynamics in Inner Mongolia from 1981 to 2010 and its impact on regional ecosystem service values were analyzed by combining multi-source data such as NDVI, GIS and the sensitivity analysis method. The results showed that:(1) although the area of deserted land in Inner Mongolia increased 69 200 km2 from 1981 to 2010, the overall degree of desertification had been controlled; the regions experiencing desertification reversion mainly concentrated in the southwest of Inner Mongolia such as Ordos and Alxa, and the areas undergone desertification expansion mainly occurred in Horqin and Otindag; (2) the total ecosystem service value decreased by 67.157 billion Yuan, and desertification dynamics had moderate linear correlation with ecosystem service value, which caused 23.7% decrease of ecosystem service value; (3) the impacts of desertification dynamics on the change of ecosystem service value in different sandy regions had spatial heterogeneity, which had promoting effects in Erdos, Otindag etc., and reverse effects in Tumd, Houshan etc.; (4) the sensitivity of ecosystem service value to desertification dynamics in different sandy regions also had obvious differences; for example, sensitivity index could reach up to more than 50 in Horqin and Hetao Plain, while it also could be lower than 1 in Hulun Buir and Houshan region. These results of the study can provide the important reference for the scientific land planning, ecological protection and sustainable development in Inner Mongolia.
