摘要
山西省管涔山林区包括森林、灌丛及亚高山草甸生态系统,鼠害较为严重。经对管涔山林区涉及的宁武、岢岚和五寨3个县的山地草原、山地草甸、疏林草地的鼠害状况进行调查,结果表现,鼠害在不同生态系统中的发生程度不同。中华鼢鼠(Myospalax fontanieri)洞穴分布密度为9.88个/hm^2~69.22个/hm^2,破害生草面积为9.25 m^2/hm^2~66.34 m^2/hm^2.达乌尔黄鼠(Spermophilus dauricus)洞穴分布密度为7.02个/hm^2~39.60个/hm^2,破害生草面积为5.86 m^2/hm^2~23.40 m^2/hm^2,中华鼢鼠鼠害高于达乌尔黄鼠。被破坏的生草面积与害鼠分布密度呈正线性相关关系,可从被破坏的生草面积推算害鼠密度,反之亦可。
Guancen Mountain in Shanxi province contained forest,shrubs and subalpine meadow ecosystems,in which the rodent calamity was relatively serious.The rodent calamity condition of mountain grassland,mountain meadows and forest grassland in Ningwu,Kelan and Wuzhai involved in the Guancen mountain area were investigated and analyzed.Results showed that the rodent calamity in different ecosystems was at different levels.Cave distribution density of Myospalax fontanieri was 9.88~69.22 per hectare,the damaged grass area was 9.25 m^2/hm^2~66.34 m^2/hm^2.Cave distribution density of Spermophilus dauricus was 7.02~39.60 per hectare,the damaged grass area was 5.86 m^2/hm^2~23.40 m^2/hm^2.The damage degree of Myospalax fontanieri was higher than that of Spermophilus dauricus.There was a positive linear correlation between the area of damaged grassland and the distribution density of rodent.The rodent density could be calculated from the damaged grass area,and vice versa.
