Connotation,attributes and application framework of geo-ecosystem products
In the context of ecological civilization,traditional geological resource concept cannot fully reflect its role,function,and value,while geo-ecosystem product provides a new approach for earth system science serving high-quality development.Based on ecological-geological system theory and value realization cascade model of ecosystem products,this arti-cle first puts forward the concept of'geo-ecosystem product'.From the perspective of feed-back mechanism,this article clarifies geo-ecosystem services.Furthermore,a value realiza-tion cascade model is constructed to illustrate forming logic of geo-ecosystem product,as well as its conceptual connotation and attribute classification.Finally,for the purpose of val-ue realization,an application framework for geo-ecosystem products is proposed to construct the value transformation chain from geological environment and resources to human well-be-ing.According to the research,geo-ecosystem product and its value realization,which are based upon geo-ecosystem holistic view,should contribute to depth and breadth of ecosystem products,and explore a geological path for rural revitalization,common prosperity,and eco-logical conservation and restoration.
