- Abstract:
-
The relationship between the spatial pattern of vegetation in a small watershed on the Loess Plateau and terrain was studied based on the geographic information system (GIS) and environment gradient analysis. Altitude, slope, aspect, and terrain niche four terrain factors were chosen, the vegetation distribution map and the gradient map of each terrain factor was superposed, and the distribution index was used to analysis the inter spatial relationships between vegetation distribution and each terrain factor. This study showed the main terrain factor on vegetation pattern and the dominance degree of different vegetation on each terrain gradient. Altitude was the main terrain factor on vegetation pattern. Bushes distribute mainly in the areas with high altitude and middling slope, crude grassland distributes mainly in the areas with the altitude lower than middling level and the slope more cliffy than middling level, artificial grassland distribute mainly in the areas with the altitude higher than middling level and the slope more gentle than middling level, arable land and orchard distributes mainly in the areas with low altitude and gentle slope. This study could offer scientific evidence for vegetation restoration and eco-environment management.
