摘要
黄河三角洲指黄河在入海口多年来淤积延伸、摆动、改道而形成的一个扇形地带,黄河水沙是维持三角洲生态环境的最基本条件。随着社会的发展,黄河三角洲地区人类活动不断加大,该地区的生态环境也面临着一些突出问题:黄河水不再泛滥,减少了对三角洲补充水沙的范围;黄河入海流量减少,进一步降低了对三角洲补水的能力;工业化进程给三角洲生态环境的健康带来了不利影响。维持三角洲生态环境健康要充分利用黄河水沙资源,将改造盐碱与保护湿地实施有机结合,积极发展生态经济。
Yellow River Delta is a fan-shaped region by sedimentation,extending,swing and diversion in Yellow River Estuary,Yellow River water and silt are most essential conditions to maintain Yellow River Delta ecological environment.With the developing of the society,mankind activities keep increasing,the ecological environment presents some extrusive problems:Yellow River doesn't overflow the dikes,but water and silt supplement range to the delta also decrease;discharge in Yellow Estuary decrease,water supplement to the delta drops further;industrialization causes adverse effect to the delta ecological environment.In order to maintain the health of the delta ecological environment,we should take full advantage of Yellow River water and silt resources,combine improvement of saline land with protecting wetlands,develop ecological economy actively.
