Description	Journal: Iop Conference Series: Earth and Environmental Science Combined with GIS and remote sensing technology, according to the eco-environment characteristics of karst rocky desertification region, a complete ecological vulnerability evaluation index system was established. The ecological vulnerability of the research area was evaluated and analysed from three aspects, including natural environment background, population characteristics, human-land relationship, and the index weight was determined by entropy method and coefficient of variation method, and the comprehensive evaluation results were obtained by comprehensive index method. The results showed that more than 80% of the regions in the study area had reached the moderate vulnerability level, and nearly 1/6 of the regions were severely vulnerable areas, showing a significant increase in distribution from east to west. Ecological vulnerability shows a significant effect of human-land relationship. With the increase of vulnerability level, the proportion of desertification area increases significantly.
