[目的]评价我国西北平原地区林业的生态服务功能。[方法]通过对西北平原地区林业的调查与监测,以县为最小单位,采取普查与典型调查相结合的调查方法,在评价上利用物质量评价法对西北地区平原林业的生态服务功能进行了评估。[结果]2005年西北地区平原林业在涵养水源、保持土壤、植被固碳、土壤固碳、植被制氧、吸收二氧化硫和滞尘方面均发挥了巨大作用,其各自生态服务功能值分别为32075.8万m3/a、2.8×106、1254、2752.8、3354.3、53.0和8510万t/a。[结论]为我国西北地区平原林业的生态服务功能研究奠定了基础。
[Objective] The research aimed to evaluate the ecological service function of forestry in Northwest Plain of China. [Method] Based on the investigation and monitoring of forestry in the Northwest Plain, taking the county as the smallest unit, adopting the survey method combining census and typical survey, the ecological service function of forestry in Northwest China Plain was evaluated Evaluation. [Result] In 2005, plain forestry in Northwest China played a great role in water conservation, soil carbon sequestration, soil carbon sequestration, oxygen production by vegetation, sulfur dioxide absorption and dust retention, and their respective ecological service functional values were 320,758,000 m3 / a, 2.8 × 10 6, 1254, 2752.8, 3354.3, 53.0 and 85.1 million t / a. [Conclusion] This laid the foundation for the research on the ecological service function of plain forestry in Northwest China.
