内蒙古农业大学东、西校区植物群落比较分析

COMPARATIVE ANALYSIS OF PLANT COMMUNITY IN EAST AND WEST CAMPUS OF INNER MONGOLIA AGRICULTURAL UNIVERSITY

本文通过对内蒙古农业大学东、西校区20个标准样方内植物群落的种群组成、丰富度指数、树种多样性、树种均匀度以及乔灌草比等指标的统计调查、分析得出:内蒙古农业大学东、西区校园绿化覆盖率相对较高,树种较为丰富;两个校区的植物结构配置及其树种丰富度、多样性与均匀度等量化指标都趋于合理,东校区的各项指标明显优于西校区,在调查的样方中群落结构配置方面要比西校区更为合理。但两个校区的落叶树比例与北方最适比例有一定的差距,且灌木数量较少,造成校园景观在垂直结构中难以形成错落有致。在今后的植物配置中应适当的引进适于北方生长的有季相变化的树种,丰富校园四季景观;增加灌木数量,注重乔灌草的合理搭配,达到整体景观效果的统一。

Based on the Inner Mongolia Agricultural University,The east and west Campus 20 standard plots of the population within the plant community composition,richness index,species diversity,evenness and the arbor,shrub and grass species than the other indicators of the survey analysis obtained： Inner Mongolia Agriculture University of East,West Campus green coverage is relatively high,more abundant species;two campuses of the plant structure configuration and tree richness,diversity and evenness and other quantitative indicators are more reasonable,the East Campus of the indicators was excellent in the West Campus,in the allocation of community structure is more reasonable than the West Campus.However,the proportion with two campuses in northern deciduous trees have a certain gap between the optimal ratio,and the small number of shrubs,resulting in the vertical structure of the campus landscape is difficult to form patchwork.Plant in the future should be an appropriate introduction for the North are seasonal changes in the growth of tree species,a rich landscape seasons on campus;increase in the number of shrubs,arbor,shrub and grass with a reasonable focus,to achieve the unity of the overall landscape effect.
