摘　　要：以2000-2013年数据为依据,基于灰色关联分析法,定量分析湿地退化影响因子关联度,为黄河三角洲湿地的监测和恢复做出科学依据,对湿地保护有重要意义.结果表明：1）近10年黄河三角洲天然湿地受到自然因素、社会因素、经济因素和环境污染因素的综合作用,面积呈现持续下降趋势.2）选取的影响因素：降水、河流径流量、来沙量、农村人口数量、城镇人口数量、城市建成区面积、道路、粮食播种面积、大牲畜存栏数量、水产品养殖量、第二产业增加值、生活污水排放量和工业废水排放量的关联度均在0.9以上,与湿地退化有很强的关联性.3）入境游客人数关联度最低为0.752,表明其关联性相对较弱,可以在湿地保护中适度发展旅游业,促进区域经济发展.According to the data from 2000 to 2013, based on the grey correlation analysis, analysis of the wetland degradation influence factors and correlation degree and the corresponding protection measures are put forward. The results showed that ： 1 ） Natural wetland of the Yellow River delta showed a trend of declining in recent 10 years by comprehensive influence with combination of natural factors, social factors, economic factors and environmental pollution factors, 2 ） Precipitation, river runoff, sediment, rural population, urban population, urban area, roads area, grain planting area, the number of herds, aquatic products, the added value of the second industry , sewage emissions and industrial wastewater emissions are above 0.9, especially the correlation of rural population, sediment, urban area and grain planting area is as high as 0.99, showing the factors has a strong a（finity. 3） The number of inbound tourists Correlation is lowest 0.752 showing relatively weak correlation. When we put forward to protect the wetland ,we can also develop tourism to promote economic prosperity.
