Temporal and Spatial Evolution Characteristics and Its Driving Mechanism of Land Use/Land Cover Change in Laos from 2000 to 2020

Land use/land cover change (LUCC) research is of great significance to land conservation and regional sustainable development. At present, there a lack on the long-term timing process mechanisms LUCC that accords with national level in Laos. Based Global Land-Cover product Fine Classification System at 30 m (GLC_FCS30) data set as well economic social statistical data, authors analyzed spatiotemporal regularity driving mechanism Laos from 2000 2020 by using dynamic degree, flow direction analysis, principal component correlation analysis other methods. The results show that: (1) rich natural ecological resources. In 2020, forest shrubland areas accounted for 53.3% 32.4% area, respectively; (2) rate across country continued rise, integrated degree was 14.4%. impervious surfaces most drastic. area evergreen broad-leaved forest, needle-leaved grassland shrink, while rainfed cropland, irrigated deciduous shrubland, wetland water body expand; (3) mainly occurred between cropland. LUC largest transfer out (8.91 × 103 km2), into (8 km2); (4) past 20 years, has been affected macro-socioeconomic development, agricultural forestry population key factor This study can provide decision-making support rational planning utilization resources
