Abstract:

Under the framework of the "Belt and Road" initiative锛� the China-Myanmar Economic Corridor has gradually moved from planning to substantive construction. Understanding the spatial pattern and distribution characteristics of land cover in Myanmar is of great strategic significance for the rational exploitation and utilization of resources and the planning of economic corridor construction. In this paper锛� a 30m resolution land cover product of Myanmar in 2015 锛坔ereinafter referred to as the MyanmarLC-2015锛� was produced using Landsat8 OLI remote sensing images锛� based on the Object-oriented Iterative Classification method based on Multiple Classifiers Ensemble 锛圤IC-MCE锛�. Besides锛� the accuracy validation of the MyanmarLC-2015 was conducted by using samples obtained from high-resolution Google Earth imagery. The verification results show that the overall classification accuracy of MyanmarLC-2015 product is 89.05%锛� the Kappa coefficient is 0.87锛� which can accurately reflect the spatial distribution characteristics of land cover in Myanmar. According to statistics锛� forest is the major land cover class in Myanmar锛� accounting for 56.15% of the total land area of Myanmar. The cultivated land area followed锛� accounting for 27.01% of the total land area. Combined with topographic factors锛� we know that with the increase of altitude锛� the appearance pattern of the typical land cover classes is tree wetlands锛� paddy fields锛� dry lands锛� deciduous shrublands锛� deciduous broadleaf forests锛� evergreen shrublands锛� evergreen broadleaf forests锛� and evergreen needleleaf forests. From the perspective of vegetation productivity锛� the NPP of vegetation is the largest in the eastern锛� northeastern and southeastern parts of Myanmar锛� while it is lower of vegetation in the central arid region and the southern Irrawaddy Delta. In 2015锛� the average of Net Primary Productivity for vegetation in Myanmar was higher in evergreen forest than deciduous forest锛� broad-leaved forest higher than shrub forest锛� and the productivity of dry land in cultivated land higher than paddy field.
