【内容概述】

黄河三角洲是中国三大三角洲之一。该区有丰富的自然资源,气候、水、土地、矿产、海洋、旅游资源丰富。但是由于人们不合理的开发利用土地和资源,使得黄河三角洲的生态环境出现了许多问题。黄河三角洲湿地是世界上最年轻、最具特色的湿地。黄河三角洲的湿地类型比较复杂,面积变化不稳定。目前黄河三角洲湿地面临大规模开发、黄河断流、湿地污染、海平面上升等问题,生态环境比较脆弱,引起了学术界广泛的关注。本文通过搜集资料,描述了三角洲的生态环境存在的问题,主要从湿地资源方面展开分析,对黄河三角洲湿地资源及其生态特征进行了分析,总结出其资源特征,描述了湿地资源的动态变化,同时根据湿地的影响因素等资料总结出湿地变化的一系列原因,主要从自然因素和人为因素两方面考虑,最后提出有利于湿地保护与可持续发展的对策建议。关键词:黄河三角洲;湿地;生态环境;变迁
 
The Research Of Yellow River Delta Ecology Environmental Change
Abstract
Yellow River Delta is one of the China's three deltas. This region possess
abundant natural resources,such as climate ,water,land,mineral and so on.But the people make much absurd exploitation for lot’s of resources,so the Yellow River Delta appears many problems about it’s ecology environment.The Yellow River Delta’s wetland is the yongest and most characteristic wetland in the word. The Yellow River Delta’s wetland form is
complex.The change of the area is not steady.Now The Yellow River Delta faces with many problems,such as large exploitation,Yellow River dry-up,Wetland pollution.The ecology environment is very weak. Through collecting data,this text describes the delta of the ecological environment problems, mainly from the aspects of wetland resources of the Yellow River delta,and its ecological characteristics of the wetland resources were analyzed,and the resources characteristics,describes the dynamic changes of the wetland resources,according to the wetland's influence factors of wetland changes summarized data from a series of reasons,mainly take the natural factors and human factors into consideration,and finally puts forward to wetland protection and sustainable development of measures.
Key words: yellow river delta; wetland; ecology environment; change
