【摘要】：植景為延續(xù)地脈與文脈,提高環(huán)境質(zhì)量所不可或缺。植物具有生命、美學(xué)、空間、文化特質(zhì),生命特質(zhì)是其根本特質(zhì)。本研究從植物生命特質(zhì)的角度出發(fā),探討群落結(jié)構(gòu)健康穩(wěn)定和相變特征合理的條件,以及其能提供的功能和達(dá)到的美學(xué)效果。植物生命特質(zhì)系指植物的生物學(xué)特征和生態(tài)習(xí)性;具有因時而變、因地而生的特點;受生長發(fā)育周期和外部環(huán)境因子的影響;表現(xiàn)為生長型和相變。參考CITY-green模型用戶手冊中的1級樹木健康狀況標(biāo)準(zhǔn),選擇武漢市公園綠地中的41處植物群落,調(diào)查群落的群體特征(植被型、結(jié)構(gòu)層次、外貌變化、使用者行為)和群落中的個體特征(生長型組成、數(shù)量、冠幅、胸徑)。分析群落整體的物種組成、植被類型,并對比不同垂直結(jié)構(gòu)下,植物群落生命特質(zhì)表征、功能和使用頻率的差異。調(diào)研結(jié)果表明:(1)調(diào)研群落在物種組成和群落結(jié)構(gòu)上與其地帶性植被相似,具有明顯的中亞熱帶濕潤氣候區(qū)域性植被特征。(2)多選擇具有較強(qiáng)適應(yīng)性和抗逆性、有良好生態(tài)效益和美學(xué)效果的鄉(xiāng)土樹種和“市花市樹”。(3)季相變化豐富,季相變化以秋季落葉樹種變色和冬春落葉樹種落葉展葉為主,此外以觀賞或展示為主的群落會強(qiáng)調(diào)葉花果的物候變化。(4)公園綠地植物群落具有滿足公眾活動和有機(jī)聯(lián)系環(huán)境的功能。(5)“喬-灌-草”垂直結(jié)構(gòu)中,林緣群落空間更適宜靜態(tài)活動;“喬-草”垂直結(jié)構(gòu)群落中,疏林草地群落空間更適宜動態(tài)活動;而“喬-灌”垂直結(jié)構(gòu)群落空間活動較少。提出植物生命特質(zhì)視角下的群落營建策略:(1)選種充分考慮氣候條件、地理分布、地域文化,以地帶性植被、鄉(xiāng)土樹種、“市花市樹”優(yōu)先。(2)群落布局和構(gòu)設(shè)宜做到物種、群落、季相、地表覆蓋多樣統(tǒng)一,以及分期規(guī)劃與動態(tài)管護(hù)。
[Abstract]:Planting scenery is indispensable for the continuation of the environment and the improvement of environmental quality. Plants have the characteristics of life, aesthetics, space, culture and life. This paper discusses the reasonable conditions for the healthy and stable community structure and phase transition characteristics, as well as the functions and aesthetic effects it can provide. Plant life traits refer to the biological characteristics and ecological habits of plants, which have the characteristics of changing from time to time and arising from local conditions. Under the influence of growth cycle and external environmental factors, the growth pattern and phase transition are represented. According to the standard of health status of grade 1 trees in the user's manual of CITY-green model, 41 plant communities in park green space of Wuhan City are selected. The population characteristics (vegetation type, structure level, appearance change, user behavior) and individual characteristics (growth type composition, quantity, crown width, DBH) of the community were investigated. The species composition and vegetation types of the community as a whole were analyzed. The characteristics, functions and frequency of plant community life were compared under different vertical structures. The results showed that the species composition and community structure of the investigated community were similar to that of their zonal vegetation, the results showed that the species composition and community structure of the investigated community were similar to those of their zonal vegetation. The local tree species with good ecological benefit and aesthetic effect have abundant seasonal variation, which have obvious regional vegetation characteristics of middle subtropical humid climate. (2) most of them have strong adaptability and resistance to stress, good ecological benefit and aesthetic effect, and the seasonal variation of local tree species and "city flower city tree" .Y3) is abundant. The seasonal changes of deciduous trees in autumn and winter and spring were mainly discoloration and defoliation. In addition, the ornamental or showcasing communities will emphasize the phenological changes of leaves, flowers and fruits. 4) the green plant community of the park has the function of satisfying the public activities and the organic connection environment. 5) in the vertical structure of "Arbor, shrub and grass", In the vertical structure community of "Arbor and grass", the space of open forest and grassland community is more suitable for dynamic activities. On the other hand, the vertical structure community of "Arbor and Irrigation" has less space activity. The community construction strategy under the view of plant life trait is put forward, which takes climate conditions, geographical distribution, regional culture into consideration and zonal vegetation. The distribution and construction of local tree species are suitable for species, community, seasonal phase, land surface coverage, as well as stage planning and dynamic management and conservation.
