海岛型城市森林景观格局效应及其生态系统服务评估
Assessment of landscape pattern effect and ecosystem services of island urban forest
摘要
Abstract
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.关键词
