【摘要】 以湖北省2009年森林资源二类清查数据为基础,野外调查数据和公开发表的文献数据为补充,采用国家林业局颁布的林业行业标准(LY/T 1721—2008)《森林生态系统服务功能评估规范》对湖北省马尾松林的生态服务功能及价值进行评估,并分析了马尾松林生态服务功能及价值的空间分异特征。结果表明:湖北省马尾松林生态服务价值为985.4。6亿元/a,单位面积生态服务价值为44 216.02元/(hm~2·a)。在水平分异上,马尾松林生态服务价值呈现鄂西、鄂东等山地丘陵地区生态服务价值大,鄂中平原地区生态服务价值小的特点;在垂直分异上,马尾松林生态服务价值随着海拔的升高而降低;在不同坡度上,斜坡和陡坡的生态服务价值较高,平坡和险坡的生态服务价值较低;在不同地貌上,低山和丘陵地区马尾松林面积较大,其生态服务价值也较高。马尾松生态服务价值高低总体上与分布面积大小相吻合。认为研究结果可为湖北省马尾松林生态服务功能的有效提升提供参考,同时还可用于指导马尾松林的空间配置与经营管理重点,为湖北省森林资源的保护和生态空间布局的优化提供科学依据。更多还原

【Abstract】 According to the standards of Specifications for Assessment of Forest Ecosystem Services in China(LY/T 1721-2008) published by State Forestry Administration,this paper evaluated the forest ecosystem services function and value of Pinus massoniana,analyzed its spatial differentiation characteristics based on the forest inventory data of Hubei Province in 2009,the published literature data and the field survey data. The results showed that the ecosystem services value of Pinus massoniana forest in Hubei was 98. 546 billion yuan/a,and the ecological service value per unit area was 44 216. 02 yuan/hm2·a. In horizontal differentiation,the ecological service value of Pinus massoniana forest was higher in Western and Eastern Hubei,lower in central area of Hubei. In terms of vertical differentiation,the value of ecological service of Pinus massoniana forest decreased with the elevation raising. The ecological service value of forest were higher on gradient slope and steep slope but lower on flat slope and dangerous slope.The area of Pinus massoniana forest in low mountains and hills was lager with higher ecological services value. The ecological service value of Pinus massoniana forest was consistent with the distribution area.The research results could provide reference for the effective improvement of the ecological service function of Pinus massoniana forest,the guide of the spatial allocation and management emphasis of Pinus massoniana forest,the protection of forest resources and the optimization of ecological spatial layout in Hubei Province.更多还原
