Abstract: Grassland is the principal part in Kangding green vegetation ecosystem and is an important part to maintain the ecological balance of Kangding. In this paper,evaluation was made on the grassland degradation in Kangding based on remote sensing and GIS technology. The grassland was evaluated into four grades including inconspicuously degraded grassland, slightly degraded grassland, moderately degraded grassland and severely degraded grassland. Then according to the evaluation results,degraded grassland spatial distribution was analyzed by combining with information of elevation,slope gradient,slope aspect and settlements. Moreover,reasons of grassland degradation were discussed,and restoration and management countermeasures of degraded grassland were also proposed in this paper.
