摘要
湿地生态系统服务价值的精准评估可为决策者平衡生态环境和经济发展之间的关系提供决策依据。该文通过市场价值法、重置成本法、旅行价值法等多种经济评估方法来估算湿地生态系统服务价值。研究结果表明:1984—2020年,北京湿地生态系统服务价值量呈波段式增长,由1984年的532.66亿元增长到2020年的1856.55亿元,其中20世纪90年代湿地生态系统服务价值快速增加,但随着社会经济发展的影响而大幅下降。2004年后湿地生态系统服务价值开始逐年提升,且维持高位水平。单项价值中北京湿地气候调节和调蓄洪水服务价值最高,休闲旅游服务价值量呈指数形增长,其他各项湿地生态系统服务价值相对稳定。研究结果可为未来城市规划和生态保护提供重要参考。
The precise assessment of the value of wetland ecosystem services can provide decision-makers with a basis for balancing ecological and economic development.This paper estimates the value of wetland ecosystem services using various economic assessment methods such as the market value method,replacement cost method and travel cost method.The study results show that from 1984 to 2020,the value of Beijing′s wetland ecosystem services increased in phases,from 53.266 billion yuan in 1984 to 185.655 billion yuan in 2020.During the 1990s,the value of wetland ecosystem services increased rapidly,but then declined significantly due to the impact of socio-economic development.After 2004,the value of wetland ecosystem services began to increase annually and remained at a high level.Among the individual values,the value of climate regulation and flood storage services of Beijing′s wetlands are the highest,the value of recreational tourism services has grown exponentially,and the value of other wetland ecosystem services are relatively stable.The study results can provide important references for future urban planning and ecological protection.
