Method for identifying spatial vulnerability of karst mountain rural settlement land

The invention belongs to the field of settlement land planning, and discloses a karst mountain rural settlement land space vulnerability identification method, which comprises the steps of obtaining partition data of karst mountain rural settlement, preprocessing the partition data, constructing a VSD model based on the preprocessed partition data, and constructing a space vulnerability evaluation index system based on the VSD model. And analyzing and calculating the spatial vulnerability evaluation index system through a geographic detector model and a global autocorrelation model in combination with a natural breakpoint grading method to obtain a spatial vulnerability spatial analysis and recognition result of the karst mountain rural settlement land. And based on the spatial vulnerability spatial analysis identification result, obtaining the vulnerability spatial distribution characteristics of the karst mountain rural settlement and the interaction mechanism of the influence factors of the vulnerability s
