| 摘 要： | 外来入侵物种已对我国生态系统功能造成严重破坏.由于没有市场交易和市场价格,采用机会成本、影子价格或影子工程费用估算外来入侵物种对生态系统服务功能造成的经济损失.在分析森林、农田、草原、湿地、草坪等生态系统服务功能价值评估的基础上,根据外来入侵物种对各类生态系统服务功能造成的损害程度,分别建立了外来入侵物种对森林、农田、草原、湿地、草坪等生态系统的间接经济损失评估模型;并在参数估计的基础上,计算了2000年外来入侵物种造成的间接经济损失. |

| Abstract: | Invasive alien species have caused to severe damage to ecosystem function. Due to lack of market deal and market price, economic losses of invasive alien species to ecosystem service function were estimated based on opportunity cost, shadow price and shadow engineering expenditure . Models of assessment of indirect economic losses caused by invasive alien species to the service function of forest ecosystems, agricultural ecosystems, grassland ecosystems, and wetland ecosystems were established, respectively. Based on the review of evaluation of service function of forest, agricultural, grassland, and wetland ecosystems, the extent of damages by alien invasive speices to the service function and indirect economic loss in 2 000 was calculated according to estimation of parameters of the models. |
| Keywords: | biological invasion economic loss model |
