摘要
In order to rehabilitate and protect the Longman mining geo-environment, the geo-environment in the Longman gold mine area is evaluated by using the GIS and RS technology and SPOT5 remote sensing data. The evaluation index system is set up, with weighted values calculated by analytic hierarchy process. The weighted average method is used to form a mathematical model and MapGIS software is used to make quantitative analyses of the cause-factors. The results basically reflect the distribution of the geological environment problems in the Longnan gold mine area.
