摘　　要：【目的】通过对公园生态系统服务价值评估,提升人们对城市公园生态系统服务功能的认知,为生态城市绿地建设的相关政策制定提供理论依据。【方法】从虎形山人防公园生态系统特征入手,确立其生态系统服务价值体系,选用当量因子法估算虎形山人防公园生态系统服务价值,并对估算结果进行检验。【结果】虎形山人防公园生态系统服务总价值为497532.17元/年,六类土地利用类型中,阔叶林服务价值最大,水系次之;11类功能服务中,水体调节和气体调节起主导作用;通过敏感性指数分析,发现估算结果准确、可信(敏感系数均小于1)。【结论】在衡阳地区,进行城市公园规划设计时,增加阔叶林和水系的比例,可进一步提升公园的生态系统服务功能和价值。【Objective】Through the evaluation of park ecosystem service value,people's cognition of urban park ecosystem service function is improved,which provides theoretical basis for the policy making of eco-city green space construction.【Method】Based on the ecosystem characteristics of Huxing Mountain Civil Air Defense Park,the ecosystem service value system is established,and the equivalent factor method is selected to calculate the ecosystem service value of Huxing Mountain Civil Air Defense Park and to test the estimation results.【Result】The total ecosystem service value of Huxing Mountain Civil Air Defense Park is 497532.17 yuan/a.Among the six land use types,the service value of broad-leaved forest is the largest,followed by water system;Among the 11 functional services,water regulation and gas regulation play a leading role.The sensitivity index analysis is used to test the calculation results.It is found that the sensitivity coefficients are less than 1,indicating that the estimation results are accurate and reliable.【Conclusion】In Hengyang region,that increasing the proportion of broad-leaved forest and water system in the urban park planning and design,could improve the park ecosystem service function and value.
