云理论在资源环境领域中的应用前景展望

The application prospect of the Membership Cloud Theory in geosciences

由中国科学家李德毅提出的隶属云概念是对模糊隶属度的发展,目前已经发展成为由云模型、云变换、云推理等组成的"云计算"理论与方法体系,其在地学界的应用尚未开展起来。模糊隶属云现象在资源环境领域普遍存在,例如环境污染等级的模糊评判、综合物化探异常含矿性的模糊识别、矿山安全评价、描述性地学数据的定量化处理、地学数据仓库的知识挖掘、地理信息系统中属性数据的不确定性处理、矿产资源评价预测等,迫切要求形成一系列数学假设和处理方法均符合多重模糊属性的处理方法。云计算理论与方法满足了这种客观需要,在地学信息处理方面具有十分广泛的应用前景。

The concept of membership cloud was proposed by Li Deyi to overcome the deficiency of Fuzzy theory.It is now developed into a series of theories,including Cloud Module,Cloud Transformation and Cloud Reasoning.Rare application of the Membership Cloud Theory（MCT,briefly） in geosciences has been found so far.Phenomenon of member cloud is common in mineral resources and environmental sciences,such as fuzzy assessment of environmental pollution grade,metallogenetic explaination of geochemical and/or geophysical anomalies,assessment of mining safety,quantitative processing of descriptive geodata,knowledge mining from data warehouse,uncertainty research of location and attribute data,and mineral resource prediction,etc.Reasonable methodologies with suitable mathematical hypothesis are strongly needed to process these problems.The creation of MCT provides edge tools for geo-data processing.
