| 摘 要： | 蚕桑生态系统服务功能价值评价对全面认识蚕桑产业价值,促进农业环境与生态系统保护具有重要意义。构成蚕桑生态系统服务功能的指标有:原材料的提供、涵养水源、土壤保护、吸收固定二氧化碳和释放氧气、废物处理、基因种质资源的保护、休闲、文化等8个类型。根据基础数据的可获得性,采用使用市场价值法、影子工程法、替代成本法、机会成本法等,初步定量评价了我国蚕桑生态系统5项服务功能经济价值。结果表明:我国蚕桑生态系统5类服务功能每年的总价值是435.72×108元,蚕桑生态系统每年提供原材料、涵养水源、土壤保护、吸收固定二氧化碳和释放氧气以及废物处理的价值分别为:8.74×108元、2.58×108元、114.34×108元、296.7×108元、13.36×108元。

| Abstract: | Sericultural ecosystem is an important part of agricultural ecosystem in China. As the basis of sustainable sericulture industry, the full assessment of sereicultural ecosystem services' value plays a significant role in the protection of agricultural environment and ecosystem. The services provided by sericultural ecosytem include production of raw materials, storage of water resource, soil conservancy, CO_2 fixation and O_2 production, waste treatment, genetic resources conservancy, recreation and culture. This paper took the first five ecosystem services as components of sericultural ecosystem services’value to estimate. Market value method, shadow engineering method, opportunity cost method and substitute cost method are employed to assess the sericultural ecosystem services’value. The results showed that the total annual value of five ecosystem services was up to 435.72×10~8 RMB Yuan. The value of production of raw materials, storage of water resource, soil conservancy, CO_2 fixation and O_2 production, waste treatment was 8.74×10~8 RMB Yuan,2.58×10~8 RMB Yuan,114.34×10~8 RMB Yuan,296.7×10~8 RMB Yuan,13.36×10~8 RMB Yuan, respectively. |
