【摘要】 以武汉市东湖湿地为研究对象,选择淡水产品、淡水资源、调蓄洪水、水质净化、固定二氧化碳、释放氧气、气候调节、休闲娱乐和科研教育共9项湿地生态系统服务价值评价指标,采用市场价值法、替代成本法、旅行费用法和科研投入法,初步评价了2017年武汉市东湖湿地生态系统的最终服务价值。研究结果表明,2017年武汉市东湖湿地生态系统的最终服务价值为7.24×109元;在9项服务价值中,气候调节服务价值相对最大,为5.81×109元,其次为休闲娱乐服务价值(1.12×109元)和调蓄洪水服务价值(2.88×108元);这3种服务价值占湿地生态系统最终服务价值的99.7%。更多还原

【Abstract】 In this study, the 9 service evaluation indexes in Donghu Lake, including freshwater products, water supply, flood regulation, water purification, carbon dioxide(CO2) fixation, oxygen(O2) release, climate regulation, entertainment, scientific research and education were selected to preliminarily evaluate the final service value of Donghu Lake wetland ecosystem in Wuhan city, using marketing value method, alternative cost method, travel expense method, and scientific research input method in 2017. The results showed that the total value of the final service value of Donghu Lake wetland ecosystem was 7.24×109 yuan in 2017. The service value of the climate regulation service was 5.81×109 yuan, which was the most valuable index and accounted for80.27% of the total value. The second and third valuable indexes were the services of entertainment(1.12×109 yuan) and flood regulation(2.88×108 yuan), accounting for 15.47% and 3.89% of the total value, respectively.The values of above three types of services accounted for 99.7% of the total value.更多还原
