calculating the data of land using / covering change of Beijing-Tianjin-Hebei urban agglomeration from 2003 to 2015 based on artificial visual analysis of Landsat TM / ETM image and product data mask of MODIS global vegetation index. The changes between types of land using and vegetation cover were comparatively analyzed. The results show that the change area of land using of Beijing-Tianjin-Hebei urban agglomeration is large，and the area of urban construction land is increasing fast that the main source is from cultivated land. The annual average vegetation coverage of urban agglomeration is increasing slightly，which the main reason was the returning farmland to forest，grassland and large growth on vegetation in some cities. The status of transformation area in forestland，grassland，wetland and urban construction land is serious，which limits the growth of vegetation coverage. It is suggested to strengthen the government’s responsibility in protecting cultivated land，construct a long-term mechanism of rational allocating land resources and improve the compensation mechanism of regional ecological construction to further promote the healthy and sustainable development of urban agglomeration.
