Abstract [Background] The reclamation area, Regiment 150 of Mosuowan is located into desert hinterland, and its north, west and east sides are surrounded by desert. The sand-preventing forest and natural desert forest are the ecological barriers of agricultural production and living environment in 150 regiments, and the study of protective benefits of shelterbelt can provide scientific guidance for the rational construction of ecological shelterbelt.[Methods] Regiment 150 in Mosuowan reclamation area were taken as the research object, the light penetrating porosity was calculated by ENVI 5.2, and the light penetrating porosity and canopy density (coverage) were selected to evaluate the sand-controlling benefits of the shelter forest.[Results] 1) The coefficient of variation (CV) of forest land area and per capita forest land occupancy for each of Regiment 150 was 64.61% and 87.89%, respectively, indicating that they were in moderate variation (10%100%), indicating that the coverage of forest land of each administrative unit was significantly different and the variation coefficient of farmland forest network of each administrative unit was 24.97%, which was a moderate variation. 2) As learned from the light penetrating porosity, most of the group farm shelterbelt's porosity was higher than 0.40, and the protection benefit of shelterbelt needed to be optimized. 3) The coverage of the peripheral shrub shelter forest ranged from 30% to 44%, belonging to moderate canopy density, the canopy density of the internal arbor shelter forest was higher than 0.70, which belonged to high canopy density.[Conclusions] Strong wind-sand erosion, insufficient water supply and high planting density are the main reasons for the large-scale degradation of the shelterbelt in the northern region, and the policy of ecological environment protection and high investment in ecological barrier construction are the main reasons for the benign development of shelterbelts in 150 regiments.
