ABSTRACT

The study have been carrying out in Tan Rai bauxite - Lam DongProvince, I have

some assessment of the environmental status here. I completed this research with practical

observations, collect data and analyze soil samples. These goals are completed include: (1) -

assess the impact of mining on the environment, (2) - The afforestation models-for soil

improvement , (3)-Impact of models Acacia planting to environment. The implementation of

this study is extremely important. Because, the miningactivities have destroyed an-huge

areaof-environment. Over the general assessment,-will help to find the better measures to

improve the environment and to-restore vegetation.In this study also shows the advantages

of Acacia auriculiformis for environmental rehabilitation.It is required to quickly implement

projects of acacia plantationto minimize the impact of mining on the soil environment.
