Outline
This paper researched the effects of disturbances of plateau pika (Ochotona curzoniae, OC), plateau zokor (Eospalax fontanierii, EF), and the symbiotic interference of plateau pika and plateau zokor (OC+EF) on plant and soil properties in three ecologically restored areas of formerly degraded alpine meadow in Henan County. It investigated how alpine meadow plant community characteristics, as measured by the changes in plant community species diversity and soil physical and chemical properties in the ecologically restored areas, responded to the disturbances of OC, EF and OC+EF. It also evaluated the effectiveness of ecological restoration in different disturbance patterns of rodents, and provided theoretical guidance to avoid secondary degradation. The results show that species richness and species diversity in the OC+EF disturbed area are significantly higher than those in the OC disturbed area. Total vegetation coverage and average plant height in the EF disturbed area are relatively high. Total vegetation coverage in the three externally disturbed areas of OC, EF, and OC+EF is 84.33%, 97.33% and 88.56%, respectively. The height of plant communities averages 47.70 cm, 168.23 cm and 139.47 cm, respectively, in the three treatments. The aboveground biomass of Gramineae, Leguminosae, Cyperaceae, and other miscellaneous herbs in EF is higher than that in OC and OC+EF. After ecological restoration, the forage yield of EF is the highest. Its soil organic carbon content is significantly higher than that of the other two disturbed areas (P0.05). The soil available phosphorus contents of OC, EF, and OC+EF are 0.053 mg·g⁻¹, 0.055 mg·g⁻¹ and 0.035 mg·g⁻¹, respectively. Judging by the comprehensive indicators of plant community characteristics and soil physical and chemical properties studied, the ecological restoration effects in the EF disturbance is the most pronounced, followed by the OC+EF disturbance, while the effects under OC disturbance is the least tangible and likely attributable to secondary degradation. Therefore, if disturbed by OC only, it is necessary to adopt non-traditional ecological restoration measures, such as increasing soil compactness during no-tillage reseeding and covering the sowed soil with non-woven fabrics, both of which will be conducive to improving the effectiveness of ecological restoration.
