扎龙自然保护区生态系统服务价值变化研究

Analysis on the Change of Eco-system Service Value in Zhalong Natural Protection Area

在Constanza生态系统服务价值理论的基础上,结合扎龙自然保护区1989年、1999年和2006年土地利用变化状况,计算出1989-2006年生态系统服务价值的变化。结果表明:土地利用类型结构的变化使生态系统服务价值发生明显变化,生态系统服务价值由1989年的7.51165×109元下降为2006年的7.26979×109元,年均损失1.423×107元;从生态系统服务功能价值看,废物处理、水源涵养和气候调节功能价值贡献率在79%以上,单项服务功能价值变化中,除食物生产功能表现增加外,其它的功能都表现降低的趋势;就生态系统服务价值构型而言,湿地系统、水域系统和草地系统的生态价值占总生态系统服务价值的97%以上,是扎龙自然保护区生态系统服务价值的主体部分,其中湿地在整个生态系统服务价值中的影响最大。

Based on the data of remote sensing images in Zhalong Natural Protection Area in the year of 1988,1999and 2006,this paper analyzed changes in land use and ecosystem service values using Costanza＇s method.The results showed that the ecosystem service values in Zhalong Natural Protection Area changed obviously owing to the land use changes,the ecosystem service value descend from 7.511 65×109 Yuan in 1989 to 7.269 79×109 Yuan in 2006,with a decrease rate of 1.423×107 Yuan per year.Among the ecosystem services,functions of waste disposal,water conservation and climate regulation were the most important parts,accounting for over 79%.In the changed value of each functions,all declined except material production service value.For the structures of ecosystem service values,wet land,water bodies and grass land were the main components,with a total contribution rate of 97%,the impact of wetland was the biggest in the ecosystem.
