- Abstract
Coupling coordination between vegetation and soil is an important symbol of positive succession during gully vegetation restoration processes. Based on the investigation and analysis of vegetation and soil of three different vegetation restoration pattern gullies, a two-level target system with nine vegetation factors and eleven soil factors was conducted, and the weights of factors were determined by analytic hierarchy process (AHP). Furthermore, models of vegetation and soil coupling degree and coupling coordinative degree were constructed. The results showed that vegetation-soil system in gullies with different vegetation restoration patterns were all in the intermediate level of coordination after twenty years of vegetation restoration. The development of vegetation and soil in Robinia pseudoacacia forest gully exhibited a synchronous style. The development of soil in Caragana korshinskii shrubland gully and natural grassland gully lagged behind the development of vegetation. Linear regression analysis showed that there were different environmental factors (vegetation community or soil conditions) impacting on different vegetation properties and soil properties. There are some differences in coupling coordination between vegetation and soil in gullies with different vegetation restoration patterns in the hilly Loess Plateau, which may resulted from the biological characteristics of the dominant species in the plant communities.
