Research Of Resource Evaluation Method Based On The Lyapunov Exponent

Evaluation of resources affected the mineral resources of each country's strategic policy formulation. Mineral resources evaluation of mineral resources is essentially the distribution of characteristics, attributes, structure, quantity, quality and extent of the study. Early research on statistical basis, with depth and understanding of the scientific and technological development, the process of mineralization, the mineralization and the causes of mineralization of the dynamics gradually introduced to the evaluation of resources. Dynamic mode combined with the geological information will be a new way to evaluate the problem.The emergence of non-linear theory, especially, the emergence of fractal and chaos theory, to the provide a new way of understanding evaluation of resources , the idea of fractal widely used in evaluation of resources to solve the problems, division of the anomalies and the background. Reserves forecast and etc. The sub-structure will certainly be the formation of deep geological background, and the formation of resources is reveals the result of undergoing a long geological evolution. The results of the dynamics of the performance characteristics of the external form, as the restriction of the awareness and the level of development of science and technology , can not understand the whole picture of the evolution, the formation of the geological resources,the form of resources of the characterization, is Fractal and dynamics of the chaos that has characterized the fractal structure. This constitutes a pair of the study target. Chaos and mineral closely linked with health, resources and the distribution of fractal, in fact that is the function of and the features of chaotic so that provide a new way of thinking.The thesis points out the feature of chaoticof the mineralization,lead into a measured norm of chaotic,introduce the method of Lyapunov calculation, and go step further on the study of Lyapunov index and mineralization is a close relationship, because of the stability of measured index, is fixed, will not changed by the selection of initial condition,so the Lyapunov index is district as seen as a good criterion of calculate the assessment district. But in order to calculate the assessment district in an element of Lyapunov index, is very difficult.To solve this problem, we can use the model unit known (statistical area), un-known model unit, the use of Lyapunov index calculation method to calculate a certain element of Li Ya Punuo Cardiff index, re-use and the least-squares regression method to identify Lyapunov index and the geology of the linear relationship between variables, to evaluate the evaluation area, it can be a certain element in the evaluation of the District of Lyapunov index This is the Lyapunov-index for evaluation of mineral resources. In addition to mapping and chaos dynamics Logistic parameters and mineralization in the comparative study, analysis of their respective advantages and disadvantages.In short, this study is based on a dynamic mechanism, with non-linear way, the resource evaluation constructed a system of evaluation methods, reflects the dynamics of this system, reveals the mineralization of the consistency with the forecast, and some traditional methods such as the characteristics of the method, this method is that the traditional methods of promotion, a possible way of resource evaluation.Practice and theoretical research shows that: resources evaluation system is a huge complex system, involving extremely extensive factors, and the level of intensity of factors, each with distinct characteristics such as time, does not necessarily meet the conditions of non-linear, on the application, it is only a level reflect certain level, but it provides a new way to understand and a level to solve the problem. At the same time on the non-linear theory and the use of non-linear approach of resource evaluation, there are still many problems to in-depth study. Nonlinear methods used in evaluation of resources and still need to continuously improve and perfect.
