【摘要】 根据中华人民共和国林业行业标准《森林生态系统服务功能评估规范》(LY/T 1721-2008),以宁夏贺兰山国家级自然保护区2015年森林资源清查数据和我国权威机构公布的社会公共数据为基础,依托国家林业局贺兰山森林生态国家定位观测研究站长期、连续、定位观测研究数据集,采用分布式测算方法对宁夏贺兰山国家级自然保护区森林生态系统服务功能进行研究。结果表明:宁夏贺兰山国家级自然保护区森林生态系统服务功能总价值量为16.8708×10~8yuan/a,单位面积价值量为60239.63yuan/(hm~2·a);各功能价值量从大到小依次为净化大气环境>生物多样性保护>涵养水源>固碳释氧>保育土壤>林木积累营养物质>森林游憩;灌木林生态系统服务功能总价值量最高以及油松林单位面积价值量最高,分别为1.47×108yuan/a和66587yuan/(hm2·a);天然林生态系统服务功能总价值量与单位面积价值量均高于人工林。更多还原

【Abstract】 According to " The Forest Ecosystem Services Function Evaluation Standards"( LY/T 1721-2008),based on the data of Ningxia Helan Mountain National Nature Reserve forest resources surveyed in 2015,and the data published by the authority of our country and the long-term observation data of Helan Ecological Observation and Research Station,combined the distributed calculation method and forestry tourism and leisure value substitution method,the ecosystem services of Helan Mountain National Nature Reserve were studied. The results show that the values of the forest ecosystem service function in Ningxia Helan Mountain National Nature Reserve were 1. 6878 billion Yuan/a,value per unit area was 60239 Yuan/( hm2·a). The functional values in the order from big to small were water conservation > biodiversity conservation > carbon fixation and oxygen release> atmospheric environment purification > soil conservation > forest nutrient accumulation > forest recreation.The total value of the ecological service function of shrubs was the highest,and the ecological service function per unit area pine forest was the highest,they were 0. 147 billion Yuan·a-and 66587 Yuan/( hm2·a),respectively. The ecosystem service total value and unit area value of natural forest were higher than the artificial forest.更多还原
