土地利用变化与陆地—海洋的相互作用

LAND USE CHANGE AND LAND-OCEAN INTERACTION

评述了土地利用变化通过对河流的水文学、营养元素、悬浮物、沉积物、水生生物的影响 ,进而对海洋产生的重要影响 ,土地利用变化是陆地—海洋相互作用发生变化的原因之一。介绍了当前北海沿岸的英国及其它一些国家实施的陆地和海洋相互作用计划的研究内容和进展 ,提出今后应加强海岸带土地利用 /土地覆盖变化研究与陆地—海洋相互作用研究的结合 。

The study on land use change and land ocean interaction is the focus of the study on global environmental change. In this paper, it is discussed that the effects of land use change on ocean by influencing the hydrology, nutrient, suspended mass, sediments and biology of river that flow into ocean. The contents and advances of research project—land ocean interaction study implemented by England and some other countries surrounding North Sea are presented. Land use change is one of the most important causes that result in the change of land ocean interaction. The objective of study on land ocean interaction is to predict the trend at the scenario of land use change in the future. So in order to better understand global change, the combining study of land use change in coastal zone and land ocean interaction should be conducted.
