China's eco-environmental sensitivity and its spatial heterogeneity

The eco environmental degradation has been attracted more and more attention in China. It is becoming a challenge for scientists to find effective measures to tackle the eco environmental problems. In this study, we reviewed the spatial pattern and correlationship of major eco environmental problems: soil erosion, desertification, salinization, and acid rain. The concept of eco environment sensitivity was proposed, and the factors which influence the eco environment sensitivity in China were analyzed, especially climatic factors were focused. A regional classification of eco environment sensitivity in China was developed, and the characteristics of each sub region of eco environment sensitivity was described.
