Multidimensional natural resource entity modeling method integrating business and ecological associations

Abstract

[Objective] The aim of the study is to address the issue of inadequate representation of entity models during the transition of natural resource management from traditional economic utilization to ecological protection and sustainable development. [Methods] The concepts and connotations of “entity” and “geographical entity” were analyzed, and the concept of “natural resource entity” was defined. A multidimensional conceptual model of natural resource entities integrating business and ecological associations was established through an “event-rule-response” integration mechanism. Business activities were abstracted as “events”, which dynamically triggered the “responses” in the ecological association network among entities through preset “rules”. A modeling process for natural resource entities based on existing data was proposed. Taking mining areas as an example of natural resource entities, a mining entity model and its multidimensional association network diagram were constructed. [Results] (1) A composite natural resource entity comprising various land types such as mining land, forest land, and dry land was successfully constructed.(2) The model not only clearly expressed the mining entity and its core attributes but also effectively represented the spatial, temporal, semantic, business, and ecological associations of the mining entity.(3) Through the event of mining rights changes, the model demonstrated the ecological responses of adjacent mining areas, surrounding forest land, and groundwater to business adjustments. [Conclusion] The natural resource entity model integrating business and ecological associations can more accurately reflect the complexity of resource management and utilization. It addresses the issue that existing models struggle to represent ecological interactions between natural resource entities and the ecological impact of business activities, providing a scientific basis for the coordinated development of ecological civilization construction and rational utilization of natural resources.
