The paper evaluates the ecological benefits in ecology shelter based on the research about four ecology shelters in Hua Machi town of Yanchi County, Ningxia Hui Autonomous Region. SPOT satellite remote sensing image in 2008 and UAV aerial image in 2013 were used to monitor and analyze the change of land application in the research area, then the ecological benefits in the area were evaluated by ecological green equivalent evaluation model. The results showed that the ecological green equivalent weight in research area had increased from 2008 to 2013, which meant that the ecological environment was improved; the ecological green equivalent weight in research area was still less than 1 in 2008 and 2013, which showed the ecological environment in shelter area was relatively weak at present; the forest coverage rate in research area was 20%, less than minimum value of UN standard, and that was higher than the coverage rate (15%) which environment-protection department required ecology county to meet. The forest coverage rate based on green equivalent weight had a large gap behind the best forest coverage rate, which indicated that the land use in the research area need more adjustment. More efforts should be made for ecology protection and restoration. Essential methods such as closing hillsides to facilitate forestation, banning raising livestock on hills, and returning the grain plots to forestry are all supposed to be continued.
