摘要

简述了黄土高原退耕还林地植被恢复的时间序列和该时序中鼢鼠种群的消长规律。通过延安市17个样地的随机抽样调查

结果表明

甘肃鼢鼠的种群密度与退耕还林地的植被覆盖度呈极显著负相关。在黄土高原

针对预防鼢鼠危害

认为幼林成林的生态安全植被覆盖度的阈值为64.15%。

Abstract

The study is carried out at Liulin and Ziaoyuan towns of Yan'an city in the loess plateau

Shaanxi province in July to September 2003.The vegetation coverage and zoker density were surveyed in seventeen one plots by random sampling.The result showed that there is a extreme significantly negative correlation between them.The higher vegetition coverage

the lower zoker's density as well as the rodent damage.The ecological threshold limit value of the vegetation coverage for forest growing safely is 64.14%.The time alignment during the vegetation renew and the regularity of growth and decline of the zoker's population on forestry-land there from the farmland in loess plateau is showed.
