摘要
至2008年,深圳市森林覆盖率达47.6%,深圳全市现有桉树林面积为3658.4 hm2,本文依此并结合相应公式得出深圳市桉树人工林的生态效益分别为:涵养水源经济价值为4336.08万元;保育土壤16389.6 t,取得的经济价值为101.77万元;固定CO2的价值为4401.38万元,制氧价值为835.02万元;生物多样性保护价值为1829.2万元。
Forest coverage of Shenzhen City was 47.6% in 2008,and it had an area of 3658.4 hm2 eucalypt plantations.Based on these data,in this paper suitable formulas were used to calculate the ecological benefits of eucalypt plantations in Shenzhen City.The results showed that the economic value of water conservation was 43.3608 million RMB,conservating soil 16389.6 t which obtained the economic value of 1.0177 million RMB;value of fixing CO2 was 44.0138 million RMB,value of manufacturing oxygen was 8.3502 million RMB;value of biodiversity conservation was 18.292 million RMB.
