摘要:本文采用野外抽樣調查與室內分析相結合的方法,對徐州市云龍山一節山改造區域未改造區植物群落的植物種類、植物配置及其生長狀況等進行調查分析,并根據一節山現有的植被狀況提出相應建議。分析結果顯示:從植物生長狀況來看,改造區與未改造區的植物大多生長狀況良好;從物種組成上看,改造區較未改造區植物種類更為豐富,物種豐富度和物種多樣性較高;從林內各層次物種組成上看,改造區林下空間豐富,具有層次感,未改造區林下空間單薄;從植物配置上看,改造區的植物配置較為復雜多樣,符合植物生態配置的原則,未改造區植物配置形式單一;從樹種選擇上看,改造區選用的外來樹種較多,未改造區鄉土樹種較多;從美學角度看,改造區的植物色彩鮮艷,秋色葉樹種較多,未改造區的植物顏色以綠色為主,較為單調。34367

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. 源¥自%六^^維*論-文+網=www.aftnzs.live
