摘要: 对稻田资源的生态服务价值重视不足是稻田保护工作的最大缺陷,导致了稻田资源流失严重。本文以苏州市水稻田为例,运用造林成本法、瑞典碳税法、制氧工业成本法、替代成本法、影子工程法、当量因子法等方法对稻田生态系统各项服务价值进行了测算。结果表明,苏州市域稻田生态系统服务净总价值量为60785.18×105元,单位面积净价值量为73111.84 元/hm2。其中,正面总价值量为68485.93×105元,环境效应负总价值量为7700.75×105元,前者为后者的8.89 倍。从稻田生态系统服务价值各部分的比例看,其实物生产价值远远低于其生态经济价值,表明了作为人工湿地生态系统,稻田生态服务价值对社会经济的可持续发展具有十分重要的作用。研究结果将有助于确定稻田保护经济补偿标准,为各级政府出台相关政策提供思路和依据

Abstract: Inadequate attention to the ecosystem service functions of paddy fields is a major problem for paddy protection, leading to a serious loss of paddy resources. Taking paddies in Suzhou City as an example, this study used afforestation cost, Swedish carbon tax, cost of oxygen- generation by industrial means, replacement cost, shadow engineering, and equivalent factor methods to estimate paddy ecosystem services values. The results show that the net total value of paddy ecosystem services in Suzhou City is 60785.18×105 RMB. The net value of per unit area is 73111.84 Yuan/hm2. Among these, the total positive value is 68485.93×105 RMB, and the total negative value of environmental impact is 7700.75×105 RMB. The positive ecosystem service value is 8.89 times of the negative value. Based on the calculation of the various parts of paddy ecosystem service value, the actual production value is much lower than the ecological economic value. This indicates that as an artificial wetland ecosystem, paddy fields and their ecological service value play a very important role to the sustainable development of the socioeconomic system. This study may help determine the economic compensation standards of paddy resource protection, providing a basis for the introduction of relevant policies at all levels of government.
