摘　　要：本文对2023年都兰县天然草地有害生物进行调查,选用路线调查方法。结果为:全县草原有害生物发生面积26.2 hm^(2)×10^(4) hm^(2),危害面积为12.39 hm^(2)×10^(4) hm^(2)。其中草原害鼠发生面积21.413 hm^(2)×10^(4) hm^(2),危害面积10.324 hm^(2)×10^(4) hm^(2);草原虫害发生面积3.333 hm^(2)×10^(4) hm^(2),危害面积1.5 hm^(2)×10^(4) hm^(2);草原毒草发生面积1.454 hm^(2)×10^(4) hm,危害面积0.566 hm^(2)×10^(4) hm^(2)。主要有自然和人为原因,为此强化有害生物预警监测和草原综合治理力度,以达到控制草原有害生物的长效性。In this paper,the pest of natural grassland in Dulan County in 2023 was investigated and the route survey method was selected.The results showed that the pest occurrence area was 26.2 hm^(2)×10^(4) hm^(2) and the harm area was 12.39 hm^(2)×10^(4) hm^(2).The pest area of grassland was 21.413 hm^(2)×10^(4) hm^(2) and the pest area was 10.324 hm^(2)×10^(4) hm^(2).The occurrence area of grassland pest was 3.333 hm^(2)×10^(4) hm^(2),and the damage area was 1.5 hm^(2)×10^(4) hm^(2).The occurrence area of toxic grass in grassland was 1.454 hm^(2)×10^(4) hm^(2),and the damage area was 0.566 hm^(2)×10^(4) hm^(2).The main causes were natural and man-made,so the early warning monitoring and comprehensive management of pests should be strengthened to achieve long-term control of grassland pests.
