湿地生态系统为人类社会提供重要服务。然而，随着人口的迅速增长和国家对粮食的需求，自20世纪50年代以来，三江平原的天然沼泽地被大规模开垦。面对这些压力，沼泽地服务通常较少受到重视。本研究采用可比价格法，跨年度评估了碳收支、水土保持、生物多样性维持和粮食生产等主要生态系统服务功能。结果表明，湿地生态系统服务功能中，碳收支价值最高，分别为1.94 × 109元和1.15 × 109元。沼泽地改造前后的水土保持价值分别为0.13 × 109元和0.02 × 109元。沼泽地生物多样性维持价值为1.05 × 109元，沼泽地粮食生产价值为1.38 × 109元。退耕前沼泽地的水土保持价值和生物多样性维持价值占退耕地粮食生产价值的85.5%。总体而言，沼泽地的转换造成了0.57 × 109元的净服务损失。研究结果为评估湿地生态系统受到干扰时生态系统服务功能的潜在损失提供了参考。
Wetland ecosystems provide important services to human societies. However, with the rapid growth of population and the national demand for food, the natural marshlands in Sanjiang Plain have been reclaimed extensively since 1950s. Faced to these pressures, marshland services had usually been paid less attention. This study evaluated the dominant ecosystem services including carbon budget, soil water conservation, biodiversity maintenance and grain production services across year by comparable price. The results indicated that carbon budget value was the highest among the ecosystem services of marshlands before and after conversion, which was 1.94 × 109Yuan and 1.15 × 109Yuan, respectively. Soil water conservation value of marshlands before and after conversion was 0.13 × 109Yuan and 0.02 × 109Yuan, respectively. Biodiversity maintenance value of marshlands before conversion was 1.05 × 109Yuan and grain production value of marshlands after conversion was 1.38 × 109Yuan. Soil water conservation value and biodiversity maintenance value of marshlands before conversion was 85.5% of grain production value of marshlands conversion to paddy fields. Overall, conversion of marshlands resulted in 0.57 × 109Yuan of net services loss. Our research provided a reference for assessing the potential loss of ecosystem services when wetland ecosystems were disturbed.
