吉林西部行政区域黄鼠分布及聚集面积的研究

Study on distribution scope and accumulation areas of Spemophilus dauricus on various administrative division in the west of Jilin Province

目的了解吉林西部各行政区域黄鼠分布范围及聚集面积。方法利用GIS和GPS对行政区域面积、黄鼠分布范围及黄鼠数量进行调查。结果吉林省西部地区黄鼠分布面积占疫源地面积的75.42%;黄鼠聚集面占疫源地面积的10.95%。结论由于大量捕杀黄鼠,以及黄鼠适宜生存环境发生变化,因而导致黄鼠聚集面和黄鼠数量明显减少。

Objective TO understand distribution scope and accumulation area of Spemophilus dauricus on various administrative division in the west of Jilin Province. Methods By GIS and GPS researching the area of various administrative division and the distribution scope and quantity of Spemophilus dauricus. Results The dispersal area of Spemophilus dauricus occupies the epidemic focus area 75.42% ; The accumulation area of Spemophilus dauricus occupies the epidemic focus area 12.63% in the west of Jilin Province. Conclusions Because Spemophilus dauricus have been captured and killed massively ,As well as its suitable survival environment have been changed,thus the accumulation areas and quantity of Spemophilus dauricus have reduced obviously.
