The rapid expansion of cropland in Cambodia, the world’s seventh-largest rice exporter, has created an imbalance land use structure. However, there is a lack quantitative investigation loss ecological as result and its drivers. In this research, spatial autocorrelation, landscape pattern index transfer matrix methods were used based on data from 2000 to 2023. Then, eXtreme Gradient Boosting-SHapley Additive exPlanations (XGBoost-SHAP) Geographic Detector explore drivers expansion. findings indicate that expanse agricultural Cambodia significantly increased by 13.47%. proportion area (37.87%) close forest (40.19%).

Analyzing vegetation coverage and land-use land cover (LULC) characteristics helps to understand the interaction between human activities natural environment. The coastal regions of Guangdong Province are economically active areas with frequent activities, located in advantageous environment South China. This study analyzed spatiotemporal normalized difference index (NDVI) LULC from 2000 2020, explore response NDVI changes changes. results show that (1) overall is relatively high, a proportion 85.37% 89.48% higher above categories, mainly distributed east west. Vegetation showed an increasing trend. (2) this area composed forest (46.5% 47.5%) cultivated (30.7% 33.4%), high-altitude plains. 2015 2020 were significant, due mutual transfer land. In addition, built-up continued expand Pearl River Delta. (3) decreases come various types land, Delta region, while increase comes stability net contribution rate change most significant (−38.903% 23.144%). has reference significance for their changes, as well management sustainable development.
