Abstract: This paper deals with efficient control and management of plateau zckor(Myospalax baileyi) and plateau pika (Ochatona curzoniae), the important rodent pests at heavy degenerative Kobresia bimilis grassland in the alpine meadow. The work was carried out at Fengxiakou, Menyuan county of Qinghai province from 1986 to 1989. In the meantime, an integrated management area about 800ha was built and a series of treatments including chemical control, oversowing grasses, fencing, graze and weed control etc. was practiced. Experimental results show that the poisoned efficiency of 0.075% Disphaeinoe-Na and 0.6% Gophacide grain baits were 85.1% and 77.3% for plateau zokor and 96.92% and 99.78% for plateau pika respectively. Oversowing, fencing, graze control etc. were organically combined after controlling the rodent pests. The vegetation of grassland was recovered and its productivity was raised at the integrated management in short period. According to determination, the biomass of forage grass increased 1.91 times at first year and 9.11 times at second year.
