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

地处全球变化敏感地区的海岸沙地的利用变化及其环境效应日益受到关注。文章通过对海岸沙地利用及其变化研究的发展历程,海岸沙地利用变化研究的案例与技术方法,海岸沙地利用变化所引起的大气环境、水环境、土壤环境、生物环境等方面的环境效应研究等文献的梳理和总结,对国内外海岸沙地利用变化及其环境效应的研究进展进行了综述,并提出了今后研究的主要方向:海岸沙地利用变化未来发展的情景模拟、海岸沙地利用演变驱动机理的定量分析、海岸沙地利用的整体生态环境效应研究、海岸沙地防护林地的合理开发与布局等。

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.
