摘  要：
文章依托宁夏银川城市森林生态系统国家定位观测研究站建设项目以及银川市森林资源二类调查资料,并结合实地补充调查,以树种、林龄组为测算单元进行分布式测算,评估了宁夏水洞沟段生态景观长廊森林涵养水源、保育土壤、固碳释氧等7项生态服务功能及其价值。结果表明:(1)水洞沟段生态景观长廊森林生态系统涵养水源2 896.18 m~3/a,保育土壤599.99 t/a,固碳释氧量603.59 t/a,积累营养物质268.71 t/a,滞尘量332 383.2 kg/a,吸收有害污染物质3 361.21 kg/a;(2)水洞沟段生态景观长廊森林生态系统服务功能价值量为为569 810.75元/a,各生态服务功能价值排序为固碳释氧(26.79%)>森林游憩(20.84%)>物种保育(18.02%)>净化大气环境>(14.45%)>保育土壤(13.34%)>涵养水源(3.30%)>积累营养物质(3.27%);(3)水洞沟段生态景观长廊森林单位面积(hm~2)生态服务功能价值为27 749.06元/a,按森林类型排序为油松林(106 945.50元/a)>桧柏林(56 640.87元/a)>侧柏林(53 624.61元/a)>软阔林(37 328.31元/a)>硬阔林(36 481.35元/a)>樟子松林(36 139.87元/a)>灌木(22 550.82元/a)。

摘  要：
Based on long-term monitoring of ecological benefits for Ningxia Key forestry projects and forest resources inventory in Shuidonggou district of Ningxia, combined with field investigation of tree species and age group as measuring units for distributed calculation, the ecological service functions and values of Shuidonggou landscape corridor were evaluated, including water conservation, soil conservation, carbon fixation and oxygen release, and so on. The results showed that:(1) Water conversation for forest ecosystem in Shuidonggou District of Ningxia was 2 896.18 m~3/a, soil conversation and fertility maintenance was 599.99 t/a. carbon fixation and oxygen generation was 603.59 t/a.Nutriment accumulation was 268.71 t/a. Removal dust was 332 383.2 kg/a. Harmful pollutant absorption was 3 361.21 kg/a.(2) Forest ecosystem service value in Shuidonggou District was 569 810.75 yuan/a.The value of ecological service function is in the order of carbon fixation and oxygen generation(26.79 %) > forest recreation(20.84 %) >biodiversity protection(18.02 %) >air purification(14.45 %) > soil conversation and fertility maintenance(13.34 %) > water conversation(3.30 %) > nutrient accumulation(3.27 %).(3) The ecological service function value per unit area was 27 749.06 yuan/a. In terms of forest types, it is in the order of Pinus tabulaeformis forest(106 945.50 yuan/a) > Juniperus chinensis(56 640.87 yuan/a) > Platycladus orientalis(53 624.61 yuan/a) > Soft broad-leaved trees(37 328.31 yuan/a)>Hard broad-leaved trees(36 481.35 yuan/a)>Pinus sylvestris(36 139.87 yuan/a) > Shrub(22 550.82 yuan/a).
