| 摘 要： | 2009—2010年,在内蒙古阿拉善左旗典型天然梭梭(Haloxylon ammodendron)林区,采用查盗开洞法调查春季和秋季的大沙鼠(Rhombomys opimus)危害情况,根据危害情况划分危害等级,同时分析了梭梭林中大沙鼠的密度与环境因子的关系,采用多元回归方法建立数学模型,并运用3S技术将大沙鼠危害等级与梭梭林分布图(1∶220万)进行叠加分析处理。结果表明,阿拉善荒漠天然梭梭林大沙鼠分布的数量与梭梭生物量、土壤水分、月降水总量呈正相关,与梭梭密度呈负相关,与降水量的相关性最大;2个年度中大沙鼠危害等级为1～4级,危害区域主要集中在阿拉善左旗东部和北部,秋季大沙鼠的危害普遍严重。该研究可以为梭梭林的鼠害监测及综合治理提供参考。 |
| 关 键 词： | 大沙鼠 梭梭林 危害等级 |

| Abstract: | The damage of Great gerbil(Rhombomys opimus)to Cakcayr(Haloxylon ammodendron)natural forest distributed on Alxa desert in Inner Mongolia of China was surveyed using the method of plugging hole and checking opening hole in autumn and spring from 2009 to 2010.Multiple regression method was used to analyze the relationship between Great gerbils abundance and environmental factors.Meanwhile,damage levels of Great gerbils were overlaid with Cakcayr forest distribution map(1∶ 2200000)to divide 4 grades based on damage conditions by 3S technology.The results indicated that Great gerbils abundance was positively correlated with Cakcayr biomass,soil moisture and monthly precipitation,negatively correlated with Cakcayr density.The correlation of Great gerbils abundance with monthly precipitation was the most significant one among all of factors.During two years,Great gerbils damaged areas were mainly distributed in the north and east of Alxa desert,and damage in autumn was more serious than spring.The "3S" technology not only reflects cakcayr forest distribution and Great gerbils damage levels accurately,but also provides an effective tool for monitoring and comprehensively managing pest rodents in Cakcayr forest. |
| Keywords: | Great gerbil Cakcayr forest rodent damage grade |
