摘要
以湖泊资源丰富的武汉市为例,通过景观格局指数测定该市湿地破碎化程度,借助GIS技术评估该市湿地生态系统服务价值,并探讨了城市湿地破碎化对生态系统服务价值的影响。结果表明:①2000—2015年武汉市湿地总体破碎化趋势有所缓和,但人工湿地相较于自然湿地破碎化程度要高,特别是2010—2015年湿地总面积下降了2.80%,而斑块密度上升了4.12%,湖泊破碎化程度较高。②2000—2015年,武汉市湿地ESV增长了323.27亿元,各类型湿地的生态系统服务价值表现为湖泊>水库坑塘>河流>沼泽。③湿地景观破碎化与部分调节性、支持性和文化性服务功能存在着显著相关关系。
Through the degree of wetland fragmentation of Wuhan from landscape pattern index,and used GIS to assess the value of wet land ecosystem services,this paper analyzed the impact of fragmentation on ecosystem services.The results showed that:①From 2000 to 2015,the fragmentation trend of wetland landscape eased,but the degree of fragmentation of constructed wetland was higher than natural wetland.Es pecially,the total area of wetland decreased by 2.80%,and the patch density increased 4.12%from 2010 to 2015.The degree of lake frag mentation was relatively high.②From 2000 to 2015,the ESV of Wuhan wetland increased by 32.327 billion yuan,the ecosystem service value of various types of wetlands was represented by lakes>reservoirs and ponds>river>swamps.③There were significant correlations between the fragmentation of wetland and some regulatory,supportive and cultural functions.
