| 为制定巢湖流域厌氧-土壤净化床工艺处理农村生活污水生态补偿标准，通过额外成本、生态服务价值增量和环境成本测算方法，确定肥东县牌坊乡中心社区应用土壤净化床的生态补偿标准。结果表明，应用土壤净化床系统处理该地区农村生活污水所需理论生态补偿量为123.24万元·hm-2·a-1，其中额外成本58.89万元·hm-2·a-1，生态服务价值增量68.11万元·hm-2·a-1，环境成本-3.76万元·hm-2·a-1。在土壤净化床运行过程中，农户可获得收益5.45万元·hm-2·a-1，无需得到额外补偿；水源涵养区政府自行承担额外成本投入的58.89万元·hm-2·a-1，下游地区政府需向水源涵养区政府补偿环境成本3.76万元·hm-2·a-1；土壤净化床工艺以47.78%额外成本补偿量在消纳废弃物上作出50.84%的补偿量贡献，同时对生态环境服务价值和环境改善作出贡献；根据生态补偿测算，尽管农村生活污水处理投入的额外建设成本较高，但通过消纳废弃物产生的生态服务价值远远大于额外成本。在水源涵养区，特别是流域保护中，厌氧-土壤净化床工艺处理农村生活污水生态补偿标准能起到较好的生态示范作用，在水源涵养等生态敏感区需要地方政府给予相关政策支持，加强生态型农村污水处理系统的推广。 |

| The extra costs, value of ecological compensation services and environmental costs were taken into account, which was to study the ecological compensation standard index system and assessment method for soil bed in the central community of Paifang Township, Feidong County as a case. The results showed that:Theoretically, the ecological compensation standard for the treatment of rural domestic sewage in Feidong County was 1.232 4×106 yuan·hm-2·a-1, and the extra costs, value of ecological compensation services and environmental costs were 5.889×105, 6.811×105, -3.76×104 yuan·hm-2·a-1 respectively. During the operation of the soil bed system, farmers could obtain a return of 5.45×104 yuan·hm-2·a-1, and need not extra compensation. The 5.889×105 yuan·hm-2·a-1 of extra costs would be undertaken by the government of water source conservation district, which should gain the compensation of 3.76×104 yuan·hm-2·a-1 of the environmental costs from the government of downstream region; The soil bed technology made up 50.84% compensation share to eliminate the waste with the 47.78% extra costs compensation, which contributed to the increment of ecological environment service value and environment improvement at the same time. According to the ecological compensation calculation, although the extra construction investment of the rural domestic sewage treatment plant was relatively high, the value of ecological service for eliminating the waste water was far greater than the extra costs. Therefore, it can play a good ecological demonstration role in the water conservation area, especially in the basin protection area. And, the relevant policy need be offered to spread ecological rural sewage treatment system in the local governments of ecological sensitive areas such as water conservation. |
