This paper
researches top-soil loss depends on Anatolian black pine stands by different canopy
density. The stand profile is playing an important role on the living and
non-living environment in the ecosystem and it affects directly canopy density
(CD), leaf area index and silvicultural treatments and indirectly affects the
soil properties. Within the scope of the study, three different canopy
densities (60%, 80%, 90%) were taken and the stand profiles were determined by
an 20x20 meter sample plots representing the stand. All sample plots were
selected under the same habitat conditions (Slope: 5%, Aspect: Northwest,
Elevation: 1070 m) to estimate top soil loss model. As a result, the amount of
top soil loss was determined as 0.052 t/ha/yr in 60% CD, 0.037 t/ha/yr in 80%
CD and 0.017 t/ha/yr in 90% CD respectively. In addition, multiple regression model
(Linear, R2=0.96) was developed to estimate annual top soil loss
depend on DBH (diameter of breast height), and tree height. On the other hand,
simple regression model (Quadratic, R2=0.98) using tree height
variable was improved. Furthermore, more advanced models can be developed in
the future by using the stand parameters in different ecological conditions and
slope gradients.
