- Abstract:
-
Identifying the distribution and patterns of karst landform is fundamental to landform interpretation and subsequent landscape structures analysis. Due to the complexity of landforms and the similarity of their growth environment, it is difficult to understand and interpret karst landform. On the perspective of geography and landscape ecology, we used GF-1 images and TM images supplemented with DEM and contour to build interpretation symbol and classification system. Finally, karst landscape patterns were analyzed combining GIS and Fragstats software. The results shows that: because of the high resolution in GF-1 image, it is more appropriate to differentiate surface morphology with a high accuracy than TM images; less affected by human activities, the karst landform in Mashan County shows low fragmentation and high naturalness, diversity, heterogeneity, integrity, all in favor of karst landscape protection; the peak clusters are dominant landscape types in Mashan County.
