协调关系存在一定差异,这可能与植物群落优势种的生物学特性密切相关。

Other 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.
