摘　　要： 依据国家林业局发布的《森林生态系统服务功能评估规范》(LY/T1721-2008),以2009年为评估基准年份,对鹤山市的森林生态服务功能价值进行评估。结果表明:鹤山市森林生态系统服务功能年总价值为73.066亿元/a,其中涵养水源、保育土壤、固碳释氧、积累营养物质、净化大气环境、生物多样性保护和森林游憩价值分别为23.858、29.017、11.975、4.536、1.360、2.301和0.019亿元/a。鹤山市杉木、马尾松、湿地松、桉树、针叶树、阔叶树、针阔混交林等7种类型森林生态系统中,单位面积年均生态服务功能价值为16.073万元/(hm2·a),其中价值最高的是阔叶树,为19.568万元/(hm2·a),最低的是桉树,为14.405万元/(hm2·a)。最后从提高森林生态系统服务功能的角度,提出了鹤山市林分改造及林业布局结构调整的建议。 According to the ＂Forest Ecosystem Services Assessment Standards＂ （LY/T1721-2008）issued by the State Forestry Administration, The forest ecosystem services of Heshan were evaluated on the base year of 2009, and for that purpose 7 major service values and their sum were calculated. The results were as follows： the total annual value of the forest ecosystem services amounted to 7306.6 million yuan, accounting for 50.75% of the city’s GDP, of which, 2385.8 million for water conservation, 2901.7 million for soil conservation, 1197.5 million for carbon fixation and oxygen release, 453.6 million for nutrient element accumulation, 136.0 million for air purification, 230.1 million for biodiversity conservation and 1.9 million for forest recreation. The average value of forest ecosystem services per unit area was 160.73 thousand yuan？hm-2？a-1. Among the seven major forests, the value of ecosystem services of the broad-leaved forest was the maximum, which was 195.68 thousand yuan？hm-2？a-1, and that of Eucalyptus plantation the minimum, was 144.05 thousand yuan？hm-2？a-1. In addition, the authors also gave some suggestions on forest improvement and planning in Heshan City based on evaluation of forest ecosystem services. These suggestions are： reducing planting area of the Eucalyptus whereas improving the broad-leaved forest, such as Acacia, Theaceae, Albizzia falcate, etc. And also the aim and measure of forestry development should be set to confirm construction, scale and special structure of the forestry.
