Evaluation of Human Settlements Environment Suitable for the Nujiang Canyon Based on AHP and GIS

Establishing the system of evaluation of human settlements environment, and habitat environment evaluation is an important content of human settlements research. Determine the evaluation index of human settlements in Nujiang canyon through AHP. And then it determined the weight of each evaluation index value using Matlab software. The evaluation index obtained the corresponding spatial data of through the GIS spatial analysis technology. Selecting all the residents of Nujiang canyon area as the evaluation object, it established connection between the spatial database and the Excel score table for habitat suitability, obtaining suitable grade of each residential. The results show that, the residential habitat suitability evaluation results and the actual living conditions are broadly consistent with the resident. And the evaluation system is scientific. Research method is effective.
