摘要： 通过市场价格法、机会成本法、影子工程法等常用生态服务价值评估方法计算出自然、农业和城市生态系统的生态服务基准价值, 利用生境质量系数和生态区位系数对海口市1998, 2004和2008年生态系统服务基准价值进行空间调整, 得到3个时期海口市生态系统服务价值的空间分布情况。结果显示, 单位面积服务价值除针叶林、红树林和橡胶林2008年较1998年减少外, 其他生态系统呈增加趋势。3期生态系统服务价值分别为58.09, 83.40和106.02亿元, 比相应年份基准价值增加?2.82%, 21.62%和30.59%; 价值构成中农业生态系统服务价值所占比例最高, 1998, 2004和2008年分别占总价值的78.60%, 80.07%和81.89%, 自然和城市生态系统服务价值增加趋势相对缓慢。

Abstract: This paper consulted basic ecosystem services value research of natural ecosystem, agricultural ecosystem and city ecosystem with market value method, opportunity cost approach and shadow engineering method, and then adjusted ecosystem services value of Haikou in 1998, 2004 and 2008 based on habitat quality and ecological location in space, obtained the spatial distribution of ecosystem services value. The result turned out that the adjusted unit area value of ecosystem functions in Haikou was increasing in the three periods, except for coniferous forests, mangrove wetlands and rubber plantation ecosystem decreased in 2008 compared to 1998. The total economic value of the ecosystem in the three periods was estimated as 58.09×108 RMB yuan, 83.40×108 RMB yuan and 106.02×108 RMB yuan respectively, increased by ?2.82%, 21.62% and 30.59% compared to the corresponding benchmark value of total ecosystem services. The ecosystem services value of agricultural ecosystem dominated the whole ecosystem services value with the proportion of 78.60%, 80.07% and 81.89% in 1998, 2004 and 2008 respectively, the growth of natural ecosystem and city ecosystem slowed down relatively.

Key words: ecosystem services value, habitat quality, ecological location, Haikou City
