- Abstract:
-
In order to study the effects of slope aspect on soil Glomalin-related soil protein (GRSP), three natural grasslands with the same site conditions which are located in sunny slope (S15°W), half sunny slope (N75°W) and shady slopes (N57°E) were selected. The rhizosphere soil and non-rhizosphere soil of the dominant species were measured after the vegetation investigation of the typical plant communities in three slopes. The results show that the GRSP content of different slopes decreases in the order:sunny slope > half-sunny slope > shady slope, and the content of T-GRSP in shady slope is significantly reduced compared with that in sunny and half sunny slope. There was no significant difference in GRSP content between different species pairs. T-GRSP has a strong rhizosphere effect, and EE-GRSP has a weak rhizosphere effect. GRSP is negatively correlated with slope aspect but is positively correlated with species and rhizosphere effect, and the rhizosphere effect is stronger than species.
