摘要
为探索在高寒草甸草场上实现对高原鼢鼠和高原鼠兔长期、稳定、有效的控制和管理,促进植被的恢复和生产力的提高,于1986—1988年在中国科学院海北高寒草甸生态系统定位站所在的门源县风匣口地区严重退化的矮嵩草草甸牧场上开展了化学灭鼠、补播牧草、围栏封育、控制放牧、化学灭杂及残鼠控制等一系列试验研究,并在盘坡地区800ha草场范围内实施上述综合治理措施。经过两年的观察,综合防治区收到了明显的经济效益和生态效益。为青藏高原草场鼠害的综合治理奠定了一定基础。
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.
