Since the late 1970s, reform and opening-up policy has been implemented in China, which brought in a great deal of foreign investment and the availability of the transition of land usufruct in both rural and urban areas. This leads to repaid urbanization and fast economic development, with an increase rate of 15% in urbanization level, an increase ratio of 2% in the urban district area and over 9% GDP growth per year. Relatively, serious eco-environment disasters occurred, such as the pollution accident in Huaihe River in 1994, the lower reaches of Yellow river drying up for 227 days in 1997, the unusual big floods in Yangtze river and Nengjiang river in 1998, the 12 dust storm events in North China which affected Beijing, Korea, and Japan in 2000, and the serious pollution accident in Huaihe River again in 2004. Integrated analysis shows that, it is mainly caused by the land use/ cover changes, the accelerating urbanization, and the rapid growth of village enterprises. The case studies in China find out that, it is very important to plan land use/cover pattern under eco-environmental security and adjust national policy of land use and environmental management friendly to ecosystem, which is not only beneficial to improve ecosystem health and environmental quality and advance sustainable development of China, but also helpful to maintain the ecosystem health in Asia and the whole world.
