This paper quantitatively evaluated the economic forest ecosystem services in the provinces of China in 2003, based on the long-term and continuous observations of economic forest ecosystems in this country, the sixth China national forest resources inventory data, and the price parameter data from the authorities in the world, and by applying the law of market value, the method of substitution of the expenses, and the law of the shadow project. The results showed that in 2003, the total value of economic forest ecosystem services in China was 11763.39 x 10(8) yuan, and the total value of the products from economic forests occupied 19.3% of the total ecosystem services value, which indicated that the economic forests not only provided society direct products, but also exhibited enormous eco-economic value. The service value of the functions of economic forests was in the order of water storage > C fixation and O2 release > biodiversity conservation > erosion control > air quality purification > nutrient cycle. The spatial pattern of economic forest ecosystem services in the provinces of China had the same trend with the spatial distribution of water and heat resources and biodiversity. To understand the differences of economic forest ecosystem services in the provinces of China was of significance in alternating the irrational arrangement of our present forestry production, diminishing the abuses of forest management, and establishing high grade, high efficient, and modernized economic forests.
本文基于对我国经济林生态系统的长期连续观测、第六次全国森林资源清查数据以及国际权威价格参数数据，运用市场价值法、费用替代法和影子工程法，对2003年我国各省经济林生态系统服务功能进行了定量评价。结果表明，2003年我国经济林生态系统服务功能总价值为11763.39×10^8元，经济林产品价值占生态系统服务功能总价值的19.3%，这表明经济林不仅为社会提供了直接产品，还具有巨大的生态经济价值。经济林各项功能服务价值大小依次为涵养水源＞固碳释氧＞生物多样性保护＞保育土壤＞净化大气环境＞营养物质循环。我国各省经济林生态系统服务功能的空间格局与水热资源及生物多样性的空间分布具有相同趋势。了解我国各省经济林生态系统服务功能的差异，对于调整我国现有林业生产的不合理布局、减少森林经营中的弊端、建设优质、高效、现代化经济林具有重要意义。
