In this study, the authors used satellite remote sensing image as the primary source of information while collecting additional data, and selected some indicators as assessment indexes such as population density, gross domestic product (GDP), land use, soil type, elevation, slope, temperature, precipitation, and vegetation index. Eco-environment vulnerability of Anning River Basin was evaluated by using the space projection pursuit model built by GIS technology and the projection pursuit algorithm. According to analytical results, eco-environmental vulnerability degrees in the study area were divided into five grades, i.e., heavy, medium, light, slight and potential. Through analyzing the evaluation results of environmental vulnerability in 1993 and 2013, the ecological vulnerability of the study area was moderate vulnerability on the whole. Due to the enforcement of the national policy and the improvement of people's awareness of environmental protection, the overall ecological environment was improved from 1993 to 2013 in the study area.
