摘要
由于各地环境条件和布氏田鼠密度与种群分布格局的差异,其为害程度很难用统一的数量化指标加以评价,造成了准确测报该鼠为害水平的困难。本文试采用模糊聚类的方法,结合该鼠数量、分布格局以及多项环境因子的定性、定量指标加以综合分析,依其聚类结果可进行该鼠为害等级的全面评价,根据作者收集的20组数据的微机处理,表明这种方法可进行大区域不同环境条件下的为害等级评价,具有良好的应用前景。
It is difficult to estimate the damage of Brandt's vole (Microtus brandti) exactly with an unified numerical standard because of the diversity of environment condition and the vole population. The use of fuzzy cluster analysis cansynthetically estimate its damage degree with the combi- nation of vole density, its population character and the environmental indexes. The result for 20 groups of data from Zhengxiangbai Qi and Xinbarhuzuo Qi, Inner Mongolia showed that the analysis can be applied to estimate the vole damage in different populations and environmental conditions in a wide area.
