人为扰动对滨海城市湿地演变的影响--以青岛市为例

Influences of anthropogenic disturbance on coastal urban wetland:taking Qingdao City for example

运用人类扰动指数和景观转换方法,分析了青岛市胶州湾海岸带的湿地演变特征。结果显示:不同时段湿地干扰类型转换模式不同,自然湿地景观被越来越多的人工湿地和其他土地分割,湿地景观格局呈现破碎化趋势;在扰动景观类型中,人为利用景观持续增加,河流入海口是人类干扰最为活跃的区域;人类干扰在1990-2000年间最强,研究区域内有88.77%的湿地面积呈现干扰增强趋势;优越的自然地理条件和经济社会快速发展中一些无序的过度开发等是湿地景观受到人类干扰的主要原因。

Anthropogenic Disturbance Index and Landscape Transformation Method are used to analyze the evolution of wetland disturbance in Jiaozhou Bay.The results show that:The conversion mode of landscape disturbance types is different,and the wetland landscape pattern presents fragmentation trend,because of the divisions of artificial wetlands and other land;Among the disturbance landscapes,the landscape of man-made non-recycling type increase more than that of man-made recycling type,and the river estuary is the most active region of strong disturbance;The conversion rate is highest between 1990 and 2000,and the area with deteriorating trend accounts for 88.77%of the total area of the entire area;Based on the natural geography condition,the wetland of Jiaozhou gulf is susceptible to human disturbances,industrial policy and economic development enhanced this process.
