- Abstract:
- The evolution of wind erosion climatic erosivity is the key to vegetation growth. Based on GIMMS NDVI3g V1.0 data, climate data, this study analyzed the change of wind erosion climatic erosivity and its impacts on vegetation growth in northern China from 1981 to 2010. The main method used in this study was the multiple scenario analysis method and the sensitivity analysis. The results show that:(1) during the period of 1981-2010, the wind erosion climatic factor index is between 10~100, the mean value is 29.4, the level of erosivity is general; the basic characteristic is gradually weakening from east to west, and gradually weakening from south to north; (2) in 1981-2010, the wind erosion climatic erosivity showed tendency to descend in northern China; The change was mainly affected by wind speed, and the correlation coefficient between the two was up to 0.95; (3) changes of wind erosion climatic erosivity had spatial heterogeneity to vegetation changes; most of the sandy areas were characterized by the significant decrease of wind erosion climatic factor index, which led to the vegetation increase; (4) the response degree of vegetation dynamics to the changes of wind erosion climatic erosivity was obviously different:vegetation dynamics were more sensitive to wind erosion climatic erosivity in Hetao Plain and Tarim Basin, etc., and the sensitivities of Yili basin, Wulanchabu and Alashan Plateau were relatively low.
