- Abstract:
- In order to explore the effects of vegetation types on soil nutrients and ecological stoichiometry in ephemeral gully of forestland in red soil region, combining the method of field investigation and indoor analysis, we analyzed soil nutrients(C,N,P)and ecological stoichiometry of top soil(0—10 cm)for ephemeral gullies with different vegetation types. The results showed that:(1)soil nutrients and ecological stoichiometry of ephemeral gully were greatly affected by vegetation types and topographic positions;(2)compared to the bare ephemeral gullies, soil nutrients of ephemeral gullies with grass and shrub increased significantly, the C, N, and P contents of grassland increased by 67.7%,51.1%,200.0%, respectively, and those of shrub land increased by 84.6%,127.0%,226.3%, respectively, while ecological stoichiometry decreased significantly(except for the C/N of grassland), the C/P and N/P decreased by 50.9%, 46.8% and 65.2%,51.1%, respectively;(3)for different topographic positions of ephemeral gully, due to the influence of sediment deposition, soil nutrient contents in groove were significantly greater than those of gully slope and edge, while no obvious regular change was found in ecological stoichiometry;(4)correlation analysis indicated that significant positive correlations were found between C, N, and P contents, and N content was the main limiting factor on C/N, P content was the main limiting factor on C/P and N/P. Although the contents of soil nutrients increased significantly, the overall level was still low in ephemeral gully of forestland in red soil region after vegetation restoration. N and P were the limiting factors on vegetation restoration in this region, and proper application of nitrogen and phosphorus fertilizer is beneficial to accelerating the process of vegetation restoration.
