Abstract:

The land use change of coastal zone is an important one among those elements affecting the coastal zone ecological environment. And it is currently attracting extensive attentions and researches from domestic and international academics. The study of the land use change of coastal zone and its impact on ecological environment is very critical to understand the regional environment evolution as well as the global change.Firstly, the status of the land use change of coastal zone in the study of global change was analyzed.The influence of the study of the land use change of coastal zone and its ecological environment impact on the following researches was elaborated including: the change of global climate;the rise of sealevel;the interaction of continent and ocean and the thus resulted shoreline change; the flux change of materials such as nutrient salt, suspended solid and sediments, etc;the coastal biological diversity and the total cycle of substances such as C, N in coastal regions and the entire global. Based on the above researches, the paper summarized the development of the study of land use change of the coastal zone and its impact on environment, concluded and analyzed the critical study content of the land use change of coastal zone and its environment effects.Finally,the outlook of the study of land use change of coastal zone and its impact on environment was proposed
