[Objective] The border zone of China

Laos

and Myanmar were used as an example to provide the basis for the rational use of land resources and the reduction and prevention of ecological risk in this area through the evaluation of the development process and ecological status of land use/cover.[Methods] Based on the remote sensing image data of land use/cover in the study area

the evolution process and ecological status of land use/cover in the 12 years from 2005 to 2017 were measured by building models

such as land-use/cover change trend and state index models.[Results] ① The study area was dominated by forest and cultivated land

and the consistency of land-use combination was strong. However

because this area is the border zone of several countries

the degree of land use in this area had some national differences. ② Over time

the structure and change range of land use in the study area underwent significant spatio-temporal and land-type differentiation. The forest land expanded significantly

the cultivated land decreased significantly

and the area of grassland and water changed relatively smoothly. The land-use change in the last six years of the study period was higher than that in the previous six years. ③ During the 12-year study period

the overall land-use change in the study area was unbalanced

and the change trend and status of different land types were significantly different. Over time

the stability of land-use change in the study area was enhanced because of the weakening of forest-land extension and expansion

but the change trend and status difference between different land-use types slightly increased. ④ Over time

the ecological status of the study area improved as a whole

and the country-specific and spatial differentiation decreased. During the 12-year study period

the ecological status of the Laos section showed the most improvement

followed by the Myanmar section and the Chinese section. The distance between the high-value zone of the ecological comprehensive function and the junction of the three countries decreased as a whole.[Conclusion] The evolution process and ecological status of land use/cover in the study area have certain characteristics of national differentiation and stage change. China

Laos

and Myanmar are continuously improving the ecological background function of their border zone.
