土地和水是人类赖以生存的两大资源。随着经济的发展和人口的增加,在河谷地区人水争地的矛盾愈来愈突出。此文基于生态学、地貌学、水文学等学科在河谷土地利用与洪水关系方面的研究成果,从生态学的角度概括和总结了河道整治、河岸带开发、河谷内人工构筑体与河流属性及洪水的关系,介绍了有关河流生态恢复研究的现状和趋势。提出运用景观生态学原理开展土地利用格局与洪水减灾和利用的研究,向自然界学习,对处理好土地利用与洪水关系有重要意义。

Land and water are two basic resources for human beings. Along with the economic development and the increase of population, the conflicts of contention for domain between human and water are becoming more and more serious in the world. Based on the research achievements in ecology, geomorphology and hydrology, the relationships between channel improvement, development of riparian zone, artificial structures and the river characteristics and flood are summarized. In addition, the present status and trends of ecological river restoration are described. It is of significance to apply the theory of landscape ecology to studying the land-use patterns related to the reduction and utilization of flood, and learn from the nature in dealing with the relationship between land-use and flood in valley.
