Abstract: In recent years, the integration of the Beijing-Tianjin-Hebei ecological environment has been difficult, which has affected the integration of Beijing-Tianjin-Hebei. The ecological compensation mechanism is one of the economic means to effectively protect the regional ecological environment. By interpreting the Landsat TM remote sensing images of 2000, 2008, 2013 and 2018 in Dingxing County of Baoding City, the changes of land types in Dingxing County was analyzed from 2000 to 2018, and the value of county's ecological service functions and the loss of development rights were calculated. The scope of ecological compensation standards was discussed. On this basis, how the region compensates the county, and how the county compensates the ecological protector were further discussed. The county's ecological compensation mechanism was established. The results show that due to the development and utilization of land, the value of ecosystem services in Dingxing County had been reduced from 861. 17 million yuan to 813. 19 million yuan, and the loss of development rights being 672. 74 million yuan, that is, the ecological compensation range of Dingxing County was 672. 74 million-813. 19 million yuan. The county's ecological compensation mechanism was to grasp the principle of "who protects, who benefits and compensated" and "equal rights and responsibilities", and the region should provide financial compensation, policy compensation, and technical compensation to the county. The county should combine the policies of the times with the townships and enterprises, environmental NGOs, farmers and herdsmen compensated to form "hematopoietic" compensation for "reasonable distribution, key attention, and social participation", thereby improving the operationality of the county's ecological compensation mechanism in the process of Beijing-Tianjin-Hebei integration.
