利用宁夏回族自治区统计局、宁夏回族自治区葡萄产业发展局和国家统计局等的相关统计数据,从食品生产、固碳释氧、净化大气、土壤保持、涵养水源、节水增效、生态旅游和生态扶贫等角度,对宁夏贺兰山东麓葡萄产业生态系统服务价值进行评估.结果表明: 1)宁夏贺兰山东麓葡萄产业生态系统服务功能价值为35.98亿元,其中直接效益为22亿元,生态效益为13.98亿元.生态效益占整个产业生态系统服务价值的38.85%.2)生态效益中,各项功能的价值量依次为: 生态扶贫>生态旅游>固碳释氧>节水增效>净化大气>土壤保持>涵养水源.3)生态效益中,生态扶贫的价值最高,占64.39%;生态旅游的价值次之,占24.47%.对葡萄产业进行生态系统服务功能价值评估,既可以让人们在看到葡萄产业直接效益的同时,又可以意识到葡萄产业所带来的生态效益.这对全面指导葡萄产业健康持续发展具有重要参考价值.

Evaluation of ecosystem service value of the grape industry at the eastern foot of Helan Mountain,Ningxia, China

Using statistical data from Statistics Bureau of Ningxia Hui Autonomous Region, the Grape Industry Development Bureau of Ningxia Hui Autonomous Region, and National Bureau of Statistics, ecosystem service value of grape industry at the eastern foot of Helan Mountain in Ningxia was evaluated from eight facets, i.e., food production, carbon fixation and oxygen release, air purification, soil conservation, water-holding, water conservation and efficiency, eco-tourism, and ecological poverty alleviation. The results showed that: 1) ecosystem service value of the grape industry was 3.6 billion (RMB), with direct benefit of 2.2 billion and the ecological benefit of 1.4 billion. Ecological benefit accounted for 38.85% of the total ecosystem service value. 2) The service value of the grape industry was in the order of ecological poverty alleviation> eco-tourism> carbon fixation and oxygen release> water conservation and efficiency > air purification > soil conservation> water-holding. 3) Among the ecological benefits, the value of ecological poverty alleviation was the highe-st, accounting for 64.39%; the value of ecotourism was the second, accounting for 24.47%. The results indicated the necessity of assessing ecosystem service value of the grape industry, which could enable people to realize the direct economic benefits as well as the ecological benefits. This study had important reference value for comprehensively guiding the healthy and sustainable deve-lopment of the grape industry.
