DPSIR测度框架下生态系统服务指标化研究

Ecosystem Service Indexation Research Based on DPSIR Framework

生态系统服务研究是生态文明建设的基础性工作之一。生态系统服务指标化是人与环境复杂系统研究的重要内容,也是为了满足生态资源开发与保护政策制定的实际需要。具体到生态系统服务指标制定与挑选环节,相关主体需要考虑生态系统服务指标的分类逻辑、表述方式、复杂程度,特别是要能与实际应用过程契合。为了增强生态系统服务指标化的内在逻辑关系,建议引入DPSIR框架,将生态功能、生态服务供给、人类福祉连接起来,强化指标系统设定的统一性。生态系统服务指标有效性的提高,可以从增进指标与指标化对象内在关系的理解,重视生物多样性、生态功能、生态系统工程及生态商品与服务供给联系的分析,增进指标系统构件逻辑衔接,提高指标框架制定的公众可理解性,增强指标设定政策与过程透明性,减少指标设定偏差,加强对指标不确定性风险研究等方面入手。

Research of ecosystem service is fundamental work of ecological civilization construction.Indexation of ecosystem service research is the present focus of human-environmental system,which is catering for the practical needs of making environmental protection policies.As to the development and selection of ecosystem index,we should concern about the logic of classification,way of presentation,extent of complexity,and in particular to agree with the practical application.In order to strengthen the inherent logic,we should utilize the framework of DPSIR to joint the ecosystem function,supply of ecosystem service and human welfare,thus enhance the integrity of ecosystem index.It is a systematic project to develop effective ecosystem index which can be carried out from providing more background knowledge about the internal relation between the index and index objects,giving more attention to the analysis on the relations of supply and demand among biodiversity,ecologic function,goods and service,improving the theoretical logic connection of components of DPSIR framework and the public acknowledge of index policies in order to make them more transparent and effective,moreover,further studying the uncertainty of ecosystem index also should be done.
