Abstract:: 21 indicators to form a karst index system of diagnosis of landscape ecological evaluation degradation were selected to develop diagnostic evaluation criteria from three aspects of the degradation of ecological landscape structure, function and environment pollution in this paper. With the set of analysis methods, a case study in Bijie was conducted. From 2003 to 2006, Bijie experienced four stages of moderate degradation, moderate degradation, light degradation and moderate degradation. Landscape degradation in the volatile, but the overall trend tended to good. Evaluation results with existing karst ecosystem health and confirms each other, the indicators of karst eco-system, landscape degradation diagnostic criteria and diagnostic method are some scientific values and have some reference value for guiding the optimization of ecological landscape karst area, designing and repairing of ecological landscape.
