It is of great significance to study on the scientific organization and integrated method of multi-source eco-environmental data in regional ecological environmental research.Taking Qomolangma National Nature Reserve in Tibet as a case study,this paper discusses the key issues related to data integration,such as data characteristics of typical plateau ecosystem,data classification and organization,data modeling,as well as data encoding and metadata,etc.We design a conceptual modeling framework of eco-environmental data integration firstly,then,provide a multi-dimensional description of the basic semantic structure,which concludes datasets hierarchy and organization,attributes encoding and metadata standards.Lastly,we construct the multi-source ecological environment database of Qomolangma Nature Reserve.Through CASE tool Microsoft Visio 2003 modeling and data pre-processing,we seamless integrate eco-environmental thematic information that stored in FGDB database.Combined with spatial cognition rules and stacking the semantic characteristics demonstrated by feature class,basic information extraction orientated data integration analysis can be completed,and new knowledge and laws can even be generated.Based on eco-environmental data organization and integration,the solution we designed for Qomolangma Nature Reserve can establish a preliminary suit of ecological information flow mapping mechanism of "data integration-information extraction-knowledge discovery",which provides the practical and reliable data infrastructure for regional eco-environmental research.
