Vegetation classification and coverage reflects the distribution and variation of plants.Based on the study area of Kunming in Yunnan Province,the temporal and spatial variation of vegetation classification and coverage in recent three years was analyzed by means of RS and GIS technology in this paper,which has important practical significance to the local ecological sustainable development.The result showed that coniferous forest and broadleaf forest were widely distributed in the study area,grassland mainly in the northern mountain valley while shrub and artificial vegetation were mainly distributed around the waters and urban areas during 2013-2015,The vegetation area of shrub and grassland decreased by 12.72% while the area of artificial vegetation and other land use increased by 12.82%.The vegetation area NDVI>0.5 in the study area increased by 31.52% with an upward trend during 2013-2014,while it decreased by 6.1% with a negative growth from 2014 to 2015.Vegetation coverage in the study area exhibited different variation characteristics according to elevation and slope difference.The areas with high vegetation coverage were mainly distributed in the altitude of>2500m and the slope gradient of>25°,while the vegetation coverage was low in the areas of altitude <1000 m and slope gradient <5°.The areas with great changes were distributed in the altitude of 1000-2500m and the slope gradient of <5°.On the contrary,the areas with little changes were found in the areas of altitude>2500m and slope gradient>25°,where there were less human activities.
