摘要：In this paper,based on the basic theory and method of wavelet transform,we systematically analyze the conditions for the combined use of a single wavelet transform and multi-scale resolution analysis.Three models of multi-scale representation of geographic data were constructed using wavelet analysis.Then,wavelet detection methods and models are used to simplify DEM data for large-scale expression of DEM data.In our research,various eco-environment data expression models are taken as an integral part of the research.Through comprehensive research on spatial data,multi-dimensional data and cartographic data,and based on the semantic correlation and the characteristics of the ecological environment,we constructed a multi-faceted expression model based on ecological utilization data.The experimental results show that different models and methods have a very obvious influence on the multidimensional expression of DEM.The defect deduction method can get N = 94.95,which belongs to the superior level.Therefore,the model proposed in this study can be used to express multi-scale ecological environment data,and it is conducive to the construction of ecological environment system and sustainable development.
