摘要: The spatial structure characteristics of landform are the foundation of geomorphologic classification and recognition. This paper proposed a new method on quantifying spatial structure characteristics of terrain surface based on improved 3D Lacunarity model. Lacunarity curve and its numerical integration are used in this model to improve traditional classification result that different morphological types may share the close value of indexes based on global statistical analysis. Experiments at four test areas with different landform types show that improved 3D Lacunarity model can effectively distinguish different morphological types per texture analysis. Higher sensitivity in distinguishing the tiny differences of texture characteristics of terrain surface shows that the quantification method by 3D Lacunarity model and its numerical integration presented in this paper could contribute to improving the accuracy of landform classifica-tions and relative studies.
