Temporal and Spatial Pattern Evolution Analysis of Ecological Environment Vulnerability in Panzhihua

In this study, the evaluation factors of Panzhihua City from 2005 to 2015 were selected from the three aspects of “ecological sensitivity-ecological resilience-ecological stress” to construct an evaluation system suitable for the ecological environment vulnerability of Panzhihua City, and explore the ecological vulnerability of each period. The law of spatial and temporal differentiation is different. The results show that: (1) The overall vulnerability of Panzhihua City from 2005 to 2015 is gradually increasing in the northwest to the southeast, and the overall ecological quality is moderate; (2) The overall ecological vulnerability index of Panzhihua City is decreasing from 2005 to 2015. It shows that the fragile situation of the ecological environment in the study area is developing in a direction of gradual recovery.
