| 摘 要： | 土地利用/覆被变化是影响海岸带环境演变的一个重要方面。文章着重从土地利用/覆被变化对温室气体释放、入海物质通量、生物多样性影响以及海岸特有自然覆被的生态环境效应角度评述了土地利用/覆被变化对海岸环境演变影响研究的内容与进展。分析指出该领域未来研究将朝更宏观综合(全球环境影响)与更微观深入(环境生物地球化学过程)两个趋向发展。可持续土地利用评价与调整、海岸环境生物地球化学过程与模拟、海岸生物多样性保护和海岸带综合管理将成为未来研究的重点。

| Abstract: | Worldwide concern about global change is resulting from the land use/cover change (LUCC) LUCC is also an important aspect of its effects on the coastal environment evolvement, which has led governments and researchers to consider international actions to address the issue, such as IGBP and its LOICZ project This paper reviews the recent achievements of studies on LUCC’s impact on coastal environment from four aspects: (1)LUCC’s impact on greenhouse gases release; (2)LUCC’s impact on nutrient and sediment fluxes flowing into ocean; (3)LUCC’s impact on coastal biodiversity; (4) Ecological effects of the special vegetation cover on the ecological environment On the base of summarizing and analysis, the paper brings forward the research trend and the future developing directions The research trend of coastal environment evolvement consequence of LUCC is going to be extremes, namely, to more macroscopical (study of global environmental change) and to more microcosmic (study of coastal environmental biogeochemistry process) The developing directions of the research in the future are introduced: Evaluation and the regulation of land use based on sustainable development; Study of biogeochemistry process and its simulation model of coastal environment. |
