摘  要:
核桃是发展山区经济的重要树种,也是一种能改善生态环境的优良树种。在界定核桃种植生态效益的概念及分析其内涵的基础上,运用文献查阅法以及专家咨询法,构建了核桃种植生态效益计量指标体系,采用等效替代法、市场价值法以及机会成本法等方法,对云南省大姚县核桃种植的生态效益进行了计量与分析,结果表明,2014年云南省大姚县核桃种植的生态效益为64.15亿元,是其经济效益的9倍多,其中涵养水源效益9.60亿元、固土保肥效益37.65亿元、固碳释氧效益7.45亿元、净化环境质量效益1.83亿元、调节区域气候效益2.46亿元、生物多样性保护效益5.16亿元。

摘  要:
Walnut is an important tree in developing the economy in remote areas and is also a good tree species to improve the ecological environment. Based on the definition of walnut planting ecological benefits,by using the method of literature review and expert consultation as well as the equivalent substitution method,market value method and opportunity cost method and other methods,this paper established the measurement index system of walnut planting ecological benefits and analyzed the walnut ecological benefit of Dayao County of Yunnan Province. The results showed that the ecological benefits of walnut planting in Dayao County is 6. 415 billion yuan in the year of 2014,9 times more than the economic benefit. The water conservation benefit for protecting fertilizer is 960 million yuan,solid soil benefit is 3. 765 billion yuan,carbon sequestration and oxygen release benefit is 745 million yuan,purifying environment benefit is 183 million yuan,regulating regional climate benefit is 246 million yuan and biodiversity conservation benefit is 246 million yuan.
