| 摘要：本文采用野外抽样调查与室内分析相结合的方法，对徐州市云龙山一节山改造区域未改造区植物群落的植物种类、植物配置及其生长状况等进行调查分析，并根据一节山现有的植被状况提出相应建议。分析结果显示：从植物生长状况来看，改造区与未改造区的植物大多生长状况良好；从物种组成上看，改造区较未改造区植物种类更为丰富，物种丰富度和物种多样性较高；从林内各层次物种组成上看，改造区林下空间丰富，具有层次感，未改造区林下空间单薄；从植物配置上看，改造区的植物配置较为复杂多样，符合植物生态配置的原则，未改造区植物配置形式单一；从树种选择上看，改造区选用的外来树种较多，未改造区乡土树种较多；从美学角度看，改造区的植物色彩鲜艳，秋色叶树种较多，未改造区的植物颜色以绿色为主，较为单调。34367 毕业论文关键词：云龙山；植物群落；调查；徐州市 Analysis of plant community a section Yunlong mountain in Xuzhou City Abstract: This paper uses the method of analysis of field sampling and indoor combination of Yunlong mountain in Xuzhou City, a section of mountain area is not transformation of plant community in the area of plant species, plant configuration and growth status of the investigation and analysis, and according to the conditions of the existing vegetation section mountain, put forward the corresponding suggestion. The analysis results shows: from plant growth situation, reform area and non transforming region of the plant is grown mostly in good condition; from the composition of species,the transformation zone than the unimproved species are more abundant, the species richness and species persity is higher in the hierarchy; from the species composition of view, the transformation zone of underground space rich, has the sense of hierarchy, the unmodified area under forest spatial thin;from the disposition of plants, plant configuration of the transformation zone is complex and perse, with plant ecological configuration principle, the unmodified area plant configuration form is unitary; from the choice of tree species, the transformation zone selection of more exotic species, native species are more without the transformation zone; from the aesthetic perspective, the transformation zone of the plant color, autumn leaf trees are more, the unmodified area of plant color with green, monotonous.
