Xiangjiang River in recent years, urbanization, industrialization process entered a rapid development stage. With the rapid development of urbanization, migration to urban rapid agglomeration, the rapid expansion of urban space to the rural areas, industrial production emit large quantities of waste water, waste gas, waste, pollution and destruction of the Xiangjiang River basin ecological environment has been, leading to effects on ecological environment the impact of rapid urbanization increasingly prominent. Therefore, in order Xiangjiang River rapid urbanization and ecological environment for sustainable development, the Xiangjiang River Basin in the context of rapid urbanization, the ecological environment effects were studied. This article in the understanding of regional sustainable development theory, on the basis of the circumstances of the man-land relationship theory, the theory of coordination and coordination of urbanization and eco-environment interaction theory, the urban complex ecological theory and combined with the Xiangjiang River Basin natural, socio-economic, ecological environment, Xiangjiang River Basin of rapid urbanization and ecological environment interaction coupling process, coupled role of law and mechanisms described, and then use factor analysis and build the Xiangjiang River Area Rapid urbanization and ecological environment and the effect of coupling coordination degree model, and then use of rapid urbanization and ecological environment and the effect of coupling coordination degree model derived from the data analysis of the Xiangjiang River Rapid Urbanization and Ecological Environment Coupling time and space characteristics and ecological environment, briefly come to the conclusion of the study. In time, the Xiangjiang River basin as a whole in the middle stage of rapid urbanization, characterized by a higher degree of coordination moderate coupling, the ecological environment to meet the needs of rapid urbanization, the effects of ecological environment driving and braking effect fluctuating effects of ecological environment drive into negatively correlated with rapid urban trend is consistent with the coordination degree C; ecological environment braking effect and rapid city into a positive correlation. In space, in 2008, the lower reaches of the Xiangjiang River ecological environment and response status is relatively poor, the ecological environment of rapid urbanization pressure upstream region is relatively good ecological environment to meet the needs of rapid urbanization; Xiangjiang River in the middle stage of rapid urbanization, the rapid urbanization of the middle and lower reaches comprehensive development level was significantly higher than the upstream region; Xiangjiang River downstream areas of rapid urbanization and ecological environment and effects of cross coupling effect is more intense than in the upstream area. And then divided into three types on the Xiangjiang River rapid urbanization and ecological environment and the effect of coupling coordination development. The first one is Zhuzhou, Xiangtan, Loudi City, Hengyang City at low to medium degree of coordination with moderate and low coupling, urbanization and ecological environment interactions more intense, the ecological environment is barely able to meet the demand for degree of urbanization, ecological environment will continue to deteriorate, the braking effect of the ecological environment of rapid urbanization increases; second Changsha City is coordinated for the low low-coupled, urbanization remained rapid development of the ecological environment can not meet the needs of urbanization degrees, urbanization and ecological environment of the degree of interaction is more intense, the deterioration of the ecological environment, but the slowdown in the rate of deterioration and improvement, the braking effect of the ecological environment play a leading role; third type is the city of Chenzhou, Yongzhou higher degree of coordination than high degree of coupling, urbanization and ecological environment in a more harmonious state, the degree of interaction is weak, the ecological environment to meet the demand for urbanization, rapid urbanization and ecological environment and the effect of the simultaneous development of ecological environment driven from the effects of a leading role . Finally, the proposed measures and specific measures to promote the coordinated development of rapid urbanization and the ecological environment of the Xiangjiang River, Xiangjiang River Basin of rapid urbanization and ecological environment and the effects of sustainable development and coordinated development.
