海岸带土地开发利用及生态环境效应研究简述

海岸带土地利用变化是影响海岸带生态环境的一个重要方面，也是目前国内外学术界广为关注和研究的热点问题，研究海岸带土地利用变化及其对生态环境的影响对于了解区域的生态环境演变乃至全球变化具有重要意义。分析海岸带土地利用变化研究在全球变化研究中的地位，阐述海岸带地区土地利用变化及生态环境效应研究，对研究全球气候变化、海平面上升、陆地与海洋交互作用及由此引起的岸线变迁、入海营养盐和悬浮物及沉积物等物质通量变化、海岸带生物多样性、海岸带区域乃至整个全球C、N等物质总循环等都具有重要意义。基于以上研究，简述海岸带土地利用变化及其对生态环境影响研究进展，总结分析海岸带土地利用变化及环境效应影响研究目标和重点研究内容

PROGRESS OF THE RESEARCH ON LAND EXPLOITATION AND ITS USE AND ECO-ENVIRONMENTAL EFFECTS OF COASTAL ZONE

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.
