摘要
以海岛型城市厦门市为研究区,利用1987—2007年5个时期的TM/ETM+遥感数据,综合运用景观要素遥感解译、景观指数法、生态服务价值量法及灰色关联分析方法,定量评价了景观格局效应对厦门城市森林生态系统服务的影响。研究结果表明:①厦门岛城市森林面积自1987年以来一直趋于减少,在2002年达到最低值;其生态服务价值同样在2002年达到最低水平,为12.81亿元/a;2007年有所上升,为13.63亿元/a,其中,占城市森林总生态服务价值比重最大的是涵养水源功能,其次为固碳释氧功能;②厦门岛城市森林生态服务价值与斑块密度、斑块数和香农多样性指数具有较高的关联度;与建成区面积的关联度较低,表明厦门岛建设用地以侵占城市森林以外的其他景观为主,岛内城市森林得到了较好的保护。
Based on five Landsat TM/ETM＋ remote sensing images of Xiamen Island acquired from 1987 to 2007 , the authors carried out the quantitative analysis and evaluation of urban landscape pattern effects on urban forest ecosystem services by using such methods as remote sensing interpretation of the landscape elements, landscape index,ecosystem services evaluation and gray relational analysis. Some conclusions have been reached：①The area of the forest in Xiamen Island had been reduced from 1987,and reached its lowest value in 2002;correspondingly, the value of ecosystem services reached its lowest value of 1 . 281 billion yuan per year in 2002 . The value of ecosystem services increased to 1. 363 billion yuan per year in 2007,of which the water conservation service value was the largest share,followed by carbon oxygen release service. ② The results of gray correlation analysis show that the urban forest ecosystem service values in Xiamen Island have a remarkable correlation with the patch density, patch number and Shannon diversity index. The lower correlation coefficient with the built - up area indicates that the land used to built-up in Xiamen Island increased at the expense of the other landscape. The urban forest in the island was under better protection.
