    Abstract: This study aimed to examine land physical change against the erodibility of soil erosion. This study
is a form of land use survey. It was performed in the Taweli watershed in the city of Palu. Sample was
randomly taken. Research variables were rainfall erosivity, physical characteristics and value of soil erodibility,
Length and Slope (LS), vegetation factor and soil management. The value of erosion was calculated based on
USLE (Universal Soil Loss Equation) method. Study result revealed that the forest had the value of soil erosion
of 0.18- 2.15 ton ha<sup>&#150;1</sup> year<sup>&#150;1</sup> that categorized as very low erosion hazard level. Mixed farming land had the value
of soil erosion of 6.97-29.29 ton ha<sup>&#150;1</sup> year<sup>&#150;1</sup> that categorized as low, shrubs was categorized into average to
heavy erosion hazardous level of 89.44<sup>&#150;1</sup>687.64 ton ha<sup>&#150;1</sup> year<sup>&#150;1</sup> and the primary forests had value of erosion of
1.68, 9.80 and 19.85 ton ha<sup>&#150;1</sup> year<sup>&#150;1</sup>, respectively which categorized as very low. Therefore, it can be inferred
that land of shrubs have high value of erosion compared to the land use for forest and mixed farming
agriculture.
