- Abstract:
-
In order to discuss the relationship between landscape pattern types and soil erosion at the scale of landscape pattern characteristics, and suggest directions for optimizing landscape patterns with soil erosion mitigation effects, taking the Naolihe basin as study area, we used 3S technology, USLE model, moving window method and semi-variogram, ordered multiple logistic regression to quantify the impact of analyzing the landscape pattern type on soil erosion from the characteristic scale. The results showed that:(1)the fragmentation of the landscape pattern in the study area increased from 2010 to 2018, and the landscape pattern type tended to shift towards a dispersed type;(2)the characteristic scales of the landscape pattern in the study area in 2010 and 2018 were 4 500 m and 4 250 m, respectively, with the latter having a more abundant landscape pattern;(3)from 2010 to 2018, the total amount of soil erosion in the study area increased slightly;(4)soil erosion intensity in the study area mainly depended on the characteristics of the current land use patches, the reticular landscape pattern type was the most effective in mitigating soil erosion at the characteristic scale, the probabilities of soil erosion intensity of reticular, finger-like, and checkerboard types were 0.53, 0.74, and 0.88 times higher than that of the dispersed landscape pattern. These results can provide the references for landscape pattern optimization and soil and water conservation management.
