摘要
参照《森林生态系统服务功能评估规范》(LY/T1721-2008),以上海市环城绿带为研究对象,在群落结构特征调查的基础上,对环城绿带温度、负离子、噪音等各项生态指标进行实地测定,并基于以上数据,定量评估上海市环城绿带的生态系统服务价值。结果表明:上海市环城绿带生态系统服务功能的总价值为73 779万元/a;7项生态系统服务价值大小依次为:调节温度>净化大气环境>涵养水源>固碳释氧>森林游憩>生物多样性保护>固持土壤。除了这7项生态系统服务价值,绿带生态系统还具有科普教育、疗养保健、改善民生等社会功能服务价值。为强化上海市环城绿带服务价值,有针对性地提出了相应建议,为绿带后续建设及管理提供一定的科学依据及发展方向。
The green belt around Shanghai was surveyed with ＂Specifications for Assessment of Forest Ecosystem Services in China＂（LY/T1721-2008）. Temperature, anion, noise and other ecological indicators of the green belt were measured based on the investigation of characteristics of the community structure. According to these data, the ecological services of the green belt were evaluated. The results showed that the total value of ecosystem services in the green belt was RMB 737.79 million every year, and the sequence of the 7 service values was as follows： temperature regulation 〉atmosphere environmental purification 〉water conservation 〉carbon fixation and oxygen release〉forest recreation〉biodiversity conservation〉soil conservation. Besides these seven service values, the green belt had other social service values, such as popular science education, health recuperation and care, improvement of livelihood and so on. To strengthen effective functions of the green belt, some relevant scientific bases and development directions were suggested for the follow-up construction of the Shanghai green belt.
