Coastal Sandy Land Use Change and Connected Environmental Effects: Progresses and Perspectives

Coastal sandy land is located in the sensitive area of global change. More and more attention has been paid to coastal land use change and connected environmental effects. In this paper, the literature concerning the study on coastal sandy land use is reviewed, the definition, distribution and area of coastal sandy land are introduced. The process of coastal sandy land research is divided into three stages: 1) the stage of aeolian geomorphology research(early stage), 2) that of coastal land resources investigation(mid stage), and 3) that of coasral land use change research(recent stage). Progress in technology of coastal land use change study at home and abroad, and the effects of the change on atmospheric environment, water environment, soil environment and biological environment are summarized. Some directions for future study of coastal land use change are suggested: scene simulation of coastal sandy land change in future, quantitative study on the driving mechanism of the coastal sandy land, overall effects of coastal sandy land use change on ecological environment, and rational exploitation and layout of forest shelter on coastal sandy land, etc.
