内陆水—陆地交错带的生态功能及其保护与开发前

内陆水／陆地交错带是陆地和水生态系统的界面区。由于它在系统间的特殊地位，近年来受到国际上生态和环境学界的格外重视。水陆交错带的生态功能有保持生物物种的多样性、拦截和过滤经过此交错带的物质流、有利于鱼类的繁育、稳定毗邻的生态系统、净化水体、减少洪水危害、保持水土等。水陆交错带的保护和科学开发都有待提高，使之在人类和自然的协调发展中发挥更大的作用。

THE ECOLOGICAL FUNCTION,PROTECTION AND UTILIZATION OF LAND/INLAND WATER ECOTONES

Land/inland water ecotones are the border zones between terrestrial and aquatic ecosys-tems. In recent years, this subject has extracted extensive research efforts internationallysince their effects in material and energy transport between ecosystems. The land/inland wa-ter ecotones have the following ecological functions: to conserve biodiversity,to filter materi-als from the water flow, to stabilize the adjacent ecosystems, to clarify water against pollu-tion,to reduce harmful flood,to retain water and nutrients,etc. It is necessary to improve thelevel of management, conservation and utilization of the ecotones so that they could playmore effects in a sympathetic development of the human society and nature.
