| 摘要: |
| 选取1995、2000、2008年为时间变化单元，以江苏省从北到南的20县市区域为空间变化单元，建立植被覆盖度、水土流失量模型，定量分析江苏省植被覆盖度和水土流失量的时空变化特征。结果表明:（1）江苏省的区域植被覆盖度时间变异较大，随时间的推移总体呈上升的趋势，其中新沂的植被覆盖度最高，扬中的植被覆盖度变化最大。（2）20个县市区域的水土流失量随时间的推移总体上有所增加，而如皋、通州、海门、东台、扬中、泰兴和兴化等区域的土流流失状况有所改善。 |

| Abstract: |
| Taking 20 countries of Jiangsu province from north to south in 1995， 2000 and 2008 for example， the models of vegetation cover， soil and water erosion were established in order to assess the spatial and temporal varia-bility of vegetation cover， soil and water erosion. The results indicated that:（1） The spatial variability of vegetation cover in the counties of Jiangsu province was comparatively obvious， and the vegetation cover in 2000， 2008 was larger than that in 1995， among the counties Xinyi owned the highest vegetation cover of Xinyi is highest， and Yangzhong showed the largest spatial variability of the vegetation cover.（2） The amount of water and soil erosion generally increased except the seven counties， i.e.， Rugao， Tongzhou， Haimen， Dongtai， Yangzhong， Taixing， and Xinghua. |
