北京森林类型生态系统服务空间异质性及其影响因素分析

Spatial heterogeneity of forest ecosystem services and influencing

  • 摘要: 量化评价生态系统服务是合理开发森林生态资源、实现其可持续发展的重要前提.本研究以北京市不同的森林类型(针叶林、阔叶林和针阔混交林)为研究对象,定量分析其生态系统服务及其权衡关系,并利用地理探测器分析其空间异质性的主要驱动因子.结果表明:1)针叶林净初级生产力(NPP)(324.08 g·m−2·a−1)大于阔叶林(303.33 g·m−2·a−1)和针阔混交林(291.74 g·m−2·a−1),环境改善服务从大到小依次为针叶林(251.91 kg·a−1)、混交林(215.39 kg·a−1)、阔叶林(155.36 kg·a−1);阔叶林产水服务和水土保持服务较高.2)各项生态系统服务空间异质性的主要驱动因子在不同森林类型中没有明显的差别,均为气候因子;产水量和环境改善的主要驱动因子为气温和降水;NPP的主要驱动因子为降水、气温和辐射.3)产水服务与NPP和水土保持之间存在协同关系,即产水服务越大时,NPP和水土保持服务也具有较大的值.4)交互探测表明,多数因子如高程与气候因子交互后,对各项生态系统服务的空间异质性的解释力度加强.因此,在以某项生态服务功能为目的进行造林时,应注重灌溉、保墒及保温等抚育措施,并综合考虑地形因子的影响.在分析人工林生态系统服务功能时还应充分考虑不同影响因子的交互作用.

     

    Abstract: Ecosystem services are natural environmental conditions and functions provided by ecosystems and their ecological processes. Quantitative evaluation of ecosystem services is an important prerequisite for sustainable ecological resources. The spatial heterogeneity of ecosystem services and influencing factors in different forest types (conifers, broadleaves and mixed forest) in Beijing were analyzed with GeoDetector. Net primary production (NPP) of coniferous forest (324.08 g·m−2·a−1) was found to be greater than broad-leaved forest (303.33 g·m−2·a−1) and mixed forest (291.74 g·m−2·a−1). Environmental improvement services were largest for coniferous forest (251.91 kg·a−1), followed by mixed forest (215.39 kg·a−1) and broad-leaved forest (155.36 kg·a−1), while both production service and soil and water conservation service were the largest for broadleaf forest. The main drivers of spatial heterogeneity of ecosystem services in different forest types were found to be meteorological factors. The main drivers of water production and environmental improvement were precipitation and temperature. The main drivers of NPP were temperature, precipitation and radiation. A synergistic relationship was found to exist between water production service, NPP and soil and water conservation: the larger the water production service, the larger the value of NPP and soil and water conservation. Interaction detection showed that most factors, such as elevation and climate factors, interacted with each other; therefore spatial heterogeneity of various ecosystem services was strengthened. When afforestation is carried out for the purpose of a certain ecological service, attention should be paid to measures such as irrigation, moisture preservation and heat preservation, influence of topographic factors should be considered. The interaction of different impact factors should be fully considered when analyzing the ecosystem service function of plantation.
