摘要：【目的】评估雄安新区森林生态系统服务功能,探究森林生态系统服务价值及其与各影响因素间的空间相关性。【方法】基于雄安新区2018年森林资源二类调查数据和相关生态观测数据,采用森林生态系统服务功能价值评估法和空间自相关法,对雄安新区森林生态系统服务功能价值及其空间分布、空间相关性进行研究。【结果】(1)2018年雄安新区森林生态系统服务功能总价值为91361.55万元。其中固碳释氧价值最高,为41838.72万元,积累营养物质价值最低,为2473.50万元。森林生态系统服务功能单位面积总价值为27.11万元·hm^(-2)。其中涵养水源功能单位面积价值高,为11.63万元·hm^(-2),积累营养物质功能单位面积价值最低,为0.64万元·hm^(-2)。(2)各森林类型中,杨树组提供的生态系统服务价值和单位面积提供的生态系统服务价值均最高,分别为67883.37万元、4.97万元·hm^(-2);灌木林组提供的生态系统服务价值最低,为171.86万元;单位面积生态系统服务价值最低是园林树组,为3.92万元·hm^(-2)。(3)保育土壤、积累营养物质、涵养水源、固碳释氧和净化大气环境5项服务功能均有较强的空间正相关性。人口密度、工业企业个数与森林生态系统各项服务功能价值呈现空间负相关性;造林面积与森林生态系统各项服务功能价值呈现空间正相关性。【结论】减少北沙口镇、大营镇、朱各庄镇、昝岗镇和雄州镇的工业企业个数,降低人口密度或增加大营镇、朱各庄镇、雄州镇、苟各庄镇的造林面积,可实现雄安新区森林生态系统各项服务功能价值的精准高效提升;加强对杨树组、其他阔叶林组和经济林组的保护力度,重视灌木林组、松柏组和园林树组的培育管理工作,注重研究区的植被更新与林相改造工作,是充分发挥和提高雄安新区森林生态系统服务价值的有效途径之一,为实现北京非首都功能疏解集中承载地和推动京津冀协同发展奠定生态基础。
【Objective】In order to evaluate the service function of forest ecosystem in Xiong’an New Area,the value of forest ecosystem service and its spatial correlation with various influencing factors were explored.【Method】This study is based on LY/T 1721—2008“Forest Ecosystem Service Function Evaluation Specification”,combined with the 2018 forest resources typeⅠsurvey data and related ecological observation data,and the forest ecosystem service value assessment method and spatial autocorrelation method were used to analyze the value of forest ecosystem service function and its spatial distribution and spatial correlation in Xiong’an New Area.【Results】(1)In 2018,the total value of forest ecosystem services in Xiong’an New Area was 91361.55×10^(4) yuan.Among them,the value of carbon sequestration and oxygen release was the highest,which was 41838.72×10^(4) yuan,and the value of accumulated nutrients was the lowest,which was 2473.50×10^(4) yuan.The total output value per unit area of forest ecosystem service function was 27.11×10^(4) yuan·hm^(-2).Among them,the unit area value of water conservation was the highest,which was 11.63×10^(4) yuan·hm^(-2),and the unit area value of accumulation of nutrients was the lowest,which was 0.64×10^(4) yuan·hm^(-2).(2)Among all forest types,the ecosystem service value provided by the poplar group and the ecosystem service value provided per unit area were the highest,which was respectively 67883.37×10^(4) yuan and 4.97×10^(4) yuan·hm^(-2);the ecological system service value provided by the shrub group was the lowest,which was 171.86×10^(4) yuan;and the lowest ecosystem service value per unit area was the garden tree group,which was 3.92×10^(4) yuan·hm^(-2).(3)The five service functions of soil conservation,accumulation of nutrients,water conservation,carbon fixation and oxygen release,and purification of atmospheric environment all had strong positive spatial correlations.The population density,the number of industrial enterprises and the value of various service functions of the forest ecosystem showed a negative spatial correlation,while the afforestation area and the value of each service function of the forest ecosystem showed a positive spatial correlation.【Conclusion】The value of forest ecosystem services can be improved accurately and efficiently by reducing the number of industrial enterprises in Beishakou,Daying,Zhugezhuang,Zangang and Xiongzhou towns,reducing the population density or increasing the afforestation area in Daying,Zhugezhuang,Xiongzhou and Gougezhuang towns.One of the effective ways to give full play to and improve the forest ecosystem service value in Xiong’an New Area is to strengthen the protection of poplar group,other broad-leaved forest group and economic forest group,pay attention to the cultivation and management of shrub group,conifer group and garden tree group,and pay attention to the vegetation renewal and forest facies transformation in the study area.This will lay an ecological foundation for the relocation of non-capital functions from Beijing and the coordinated development of the Beijing-Tianjin-Hebei Region.
