摘要:

城镇道路绿地是城镇绿地的重要组成部分,本文以浙江省永嘉县城镇道路绿化工程为案例,比较研究不同管理模式下城镇道路绿地的生态系统服务价值和生态成本。结果表明:生态化管理模式可以有效降低永嘉县城镇道路绿地的生态成本,该管理模式下永嘉县城镇道路绿地的生态系统服务净价值较常规管理模式高近50%。常规农业化管理模式下,永嘉县城镇道路绿地具有提供产品价值,其生态系统服务净价值较常规管理模式高16.6%。生态农业化管理模式下永嘉县城镇道路绿地的生态系统服务价值率达到常规管理模式的4.5倍以上。常规管理模式下永嘉县城镇道路绿地的生态成本十分巨大,其中超过60%来源于化肥污染环境。建议政府部门在城镇绿地管理中逐步实行生态农业化管理模式,提高城镇绿地的生态系统服务净价值和价值率。

Abstract:

Urban road green space is an important component of urban green space. With the rapid development of traffic,urban road green space is receiving increasing attention due to its ecological function. However,studies into the ecological costs of urban road green space such as resource consumption and environmental pollution are rare. Here,we established urban road green space ecosystem service values,ecological costs and net ecosystem service values evaluation models using prior work on ecosystem service value. We used urban road afforestation engineering in Yongjia county as a case study to evaluate ecosystem service values and ecological costs of urban road green space under different management modes. The results showed that the ecological costs of urban road green space in Yongjia County declined in the eco-management mode,so net ecosystem service values of urban road green space were nearly 50% higher than those under the general management mode. Under the general agricultural management mode,urban road green space in Yongjia provides product value and net ecosystem service values were 16.6% higher than in the general management mode. The rate of ecosystem service value of urban road green space in Yongjia under an eco-agricultural management mode were more than 4.5 times that in the general management mode. In the general management mode,ecological costs of urban road green space were enormous,among those costs,environment pollution caused by chemical fertilizer accounted for more than 60%. We suggest that urban green space should be managed using an eco-agricultural management mode so that people can maximize its ecological benefit.
