[Responses of plant C:N:P stoichiometry to soil properties on unstable slopes of dry-hot valley].

In this study, we examined plant C:N:P stoichiometry of herbaceous plants in different sections (stable area, unstable area and deposition area) of the unstable slope on both shade and sunny aspects of dry-hot valley with different soil properties. The results showed that C concentration (320.59 g·kg), N concentration (12.
