Abstract

Study on sloping land propertiesin Phu Luong District shows that the soil environment is influenced by two main factors: climate and human resources. The influence of rainfall on vegetation (NDVI index) affects the distribution of plants. At different slopping gradients, there are different NDVI index and different types of vegetation at different slopes have different soil properties. The soil has a high level of sour to medium sour, total nitrogen content and total humus levels are poor to medium, low K2O content, low P2O5 content, Ca2 + exchanged in the soil in low to medium, the content of Mg2+ exchange rate is very low to low, heavy metal contents (As, Pb, Cd) are lower than Vietnamese standard regulation (QCVN 03-MT). On rice growing land and tea have a higher heavy metal contents than forest plants such as acacia. Residue levels of plant protection chemicals have not been detected.
