| 摘 要： | 草原鼠害严重威胁我国草地畜牧业的可持续发展,基于“3S”技术的草原鼠害监测方法的研究在草原害鼠防治与管理方面具有重要意义。本研究以青海省为例,将“3S”技术与地面实地调查数据相结合,考虑影响草原鼠害的主要因素,建立了基于“3S”技术的草原鼠害监测模型。研究结果表明,1)草原鼠害监测模型模拟出鼠害分布的阈值主要集中在0.344 1~0.378 2,不同鼠种在不同鼠害程度的阈值均不相同;2)模拟结果总体面积为实地调查面积的1.80倍,覆盖了实地调查区域的99.95%,两者反映的整体鼠害区域基本一致。该方法为有效治理鼠害提供决策支持,对有效保护草地生产力和实现草地畜牧业的可持续发展具有重要的研究价值。

| Abstract: | Grassland rodents seriously threaten the sustainable development of pasture husbandry in China. Monitoring grassland rodents with 3S technologies plays an important role in grassland rodents control and management. Using 3S technologies and field survey data, the main factors influencing the occurrence of grassland rodent hazard in Qinghai were used to build grassland rodent monitoring models. The threshold of the rodents region ranged from 0.344 1-0.378 2, and the thresholds of different rodent regions differed at different rodent hazard levels. The rodents area was 1.80 times larger than the area provided by the field survey and covered 99.95% of the area from the field survey. The model can well simulate the rodents area in this study region. The model simulation with 3S technologies can provide decisive support for grassland rodents management, and plays a pivotal role in protecting grassland productivity effectively and in realising the sustainable development of grassland animal husbandry. |
