自1988～1993年在内蒙古半荒漠区约11万km2的调查区域内共设置259个样方,布放有效夹日131109个,捕获啮齿动物19种。在此基础上,用其捕获率作为分类量纲,以样方-种的捕获率组成259×19的原始数据矩阵,应用快速聚类法进行鼠类群落划分,根据分类结果,并结合调查区域内各种地带性植被的特点将该地区啮齿动物划分为9个不同的鼠类群落。即群落:戈壁五趾跳鼠+五趾跳鼠+长爪沙鼠群落,群落生境为半荒漠区内典型的高平原、丘陵荒漠草原;群落:三趾跳鼠+子午沙鼠+小毛足鼠群落,群落生境为沙地,主要分布于阴山北麓的覆沙地带;群落;草原黄鼠+五趾跳鼠+长爪鼠群落,群落生境为半荒漠区内平原丘陵典型草原和山地典型草原;群落:赤颊黄鼠+黑线毛足鼠+五趾跳鼠群落,群落生境为戈壁针茅-隐子草草原;群落:戈壁五趾跳鼠+三趾跳鼠+蒙古羽尾跳鼠群落,群落生境为草原化荒漠,主要以强旱生灌木和半灌木组成;群落:黑线仓鼠+长爪沙鼠+小毛足鼠群落,群落生境为人工草地及阴山北麓山顶种植荞麦和莜麦的农田;群落:小毛足鼠+三趾跳鼠+长爪沙鼠群落,群落生境为典型荒漠草原重度退化的短花针茅冷蒿草场;群落:长尾仓鼠+大林姬鼠+棕背群落,群落生境为阴山山脉中段的次生林地如五当召、大桦背及蛮汉山;群落:五趾跳鼠+草原黄鼠+黑线毛足鼠群落
A total of 259 quadrats were set up in the survey area of about 110,000 km2 in the semi-desert area of Inner Mongolia from 1988 to 1993, 131,109 effective days were placed and 19 rodents were captured. On this basis, using the capture rate as the classification dimension, the original data matrix of 259 × 19 was formed by the sampling rate of quadrats and species, and the rapid clustering method was used to classify the rodent communities. According to the classification results and combined with the survey area The characteristics of various zonal vegetation within the area divide the area’s rodents into nine different rodent communities. Namely, the community: Gobi five-toed jumping rat + five-toed jumping rat + Meriones unguiculatus community, the community habitat for the typical semi-desert region of the high plains, hilly desert steppe; community: Triratus sibirica + meridian gerbil + The communities and habitats are sandy land, which are mainly distributed in the overlying sand zone in the northern foot of Yinshan Mountain. The community, the prairie steppe, the five-toed hopper and the long-legged rat community are the typical grassland in the plain and hilly plain in the semi- ; Community: Cheek squirrel + Black line haired foot mouse + Pentaphyllum simvastatus community, the community habitat is Gobi Stipa - Hedysarum grassland; Community: Gobi five-toed jumping mouse + Three-toed hopper + , The community habitat is grassland desertification, mainly composed of strong dry shrubs and semi-shrubs; Community: black line hamster + Meriones unguiculatus + Scylla serrata community, the community habitat for the artificial grassland and the Yinshan North Peak planted buckwheat and oats The community: Hypsizygoticis + Trimatis gigantica + Mongolian gerbil (Meriones unguiculatus) community, the community habitat is the severely degraded Hedysarum chinensis grassland with typical degradation in the typical desert steppe. The community: Hamster + Apodemus agrarianus + Habitat for the community Habitat for the middle of the Yinshan Mountains secondary forest such as Wudang, Da Hua back and Man Han Shan; Community: Pestis + grasshopper + grassland Black Coatfoot community
