摘  要:
采用基于RS/GIS技术的马鞍山市2017年林地落界成果数据库及森林资源统计更新数据,对马鞍山市森林生态系统服务功能物质量和价值量进行评估。结果表明:马鞍山市2017年森林生态系统服务功能价值总量141. 53亿元,其中生态服务价值129. 15亿元,林果产品价值12. 38亿元,生态服务价值是林果产品价值的10. 4倍。8项生态服务价值排序:涵养水源(58. 3亿元)、生物多样性(22. 92亿元)、固碳释氧(22. 16亿元)、净化大气环境(9. 34亿元)、森林防护(7. 42亿元)、营养积累(4. 48亿元)、保育土壤(2. 34亿元)和森林游憩(2. 19亿元)。评估为更好地认识森林在生态环境建设中的作用、制定森林资源保护管理及森林生态补偿政策提供依据。

摘  要:
Based on land use data acquired by GIS and RS technologies and data of forest resources statistics update,we evaluated the mass and functional service value of forest ecosystem in Ma'anshan. The results showed that the total value of the forest ecosystem services in the city of Ma'anshan in 2017 was 14. 153 billion yuan,among which the value of the ecological service was 12. 915 billion yuan,the value of the forest products was 1. 238 billion yuan. The value of the ecological service was 10. 4 times of the value of the forest products. The value of eight ecological services was presented in sequence of storage and retention of water(5. 83 billion yuan),biodiversity conservation(2. 292 billion yuan),fixing carbon and releasing oxygen(2. 216 billion yuan),air cleaning capacity(0. 934 billion yuan),forest protective efficiency(0. 742 billion yuan),nutrient accumulation(0. 448 billion yuan),soil conservation(0. 234 billion yuan) and forest recreation(0. 219 billion yuan). The result of the assessment provides a basis for the better understanding of the role of forests in the construction of ecological environment,the development of forest resources protection and the policy of forest ecological compensation.
