      abstract = {With four ecological migration zones in Huamachi Town of  Yanchi County in Ningxia Autonomous Region as the object of  study, we carry out the evaluation of ecological benefits  in ecological migration zone. Using the SPOT satellite  remote sensing image in 2008 and UAV aerophotographic image  in 2013, we first monitor and analyze the land use change  over five years in the study area, and then adopt  ecological green equivalent evaluation model for the  evaluation of ecological benefits in the ecological  migration zone. Studies have shown that: (i) from 2008 to  2013, the ecological green equivalent in the study area was  increased and the ecological environment was improved; (ii)  the ecological green equivalent in the study area was less  than 1 in 2008 and 2013, and ecological environment was  still fragile in the migration zone; (iii) the forest  coverage rate of the study area was 20% less than the  minimum forest coverage rate of the United Nations, but 15%  higher than the forest coverage rate of the Ministry of  Environmental Protection. There is a large gap between the  forest coverage rate based on ecological green equivalent  and optimal forest coverage rate, suggesting that the land  use still needs to be adjusted in study area, and it is  necessary to increase efforts to strengthen ecological  restoration and continue to implement forest conservation,  returning land for farming to forestry and other measures.},
