【摘要】：節(jié)約型園林是資源節(jié)約型、環(huán)境友好型社會建設(shè)的重要組成部分，是未來城市園林的發(fā)展方向。植物群落作為園林綠地景觀中唯一的生命體，在園林綠化中占有重要的地位。植物群落的優(yōu)化模式構(gòu)建不僅可以為人們創(chuàng)建生態(tài)、和諧的生活環(huán)境，同時也有利于節(jié)約型社會的發(fā)展。本論文的主要研究結(jié)果如下： 本研究主要以華東沿海地區(qū)的寧波和西南內(nèi)陸地區(qū)的瀘州為代表，兩地同屬于中亞熱帶地區(qū)，但各具特色，選取了寧波月湖公園、鄞州公園、日湖公園、姚江公園和瀘州忠山公園、濱江公園、龍透關(guān)公園為研究區(qū)域，對其中60個典型植物群落內(nèi)的物種組成、樹種重要值、群落類型和物種多樣性進(jìn)行調(diào)查分析。結(jié)果表明：寧波調(diào)查的30個樣地中共有種子植物126種，隸屬于55科97屬；瀘州調(diào)查的30個樣地中共有種子植物136種，隸屬于62科110屬。物種組成上多以鄉(xiāng)土植物為主，但是重要值較高的植物種類只占小部分比例，說明兩地植物種類單一且貧乏。群落類型以常綠落葉闊葉混交林為主，群落結(jié)構(gòu)層次簡單。 通過實地調(diào)研分析，建立合理的評價體系，對60個典型植物群落從生態(tài)度、景觀度和節(jié)約度三個要素上選用12個評價因子采用層次分析法進(jìn)行綜合評價。評價結(jié)果顯示：寧波、瀘州共60個植物群落綜合評價等級主要集中在第Ⅱ個等級，第Ⅰ級的只有極少數(shù)幾個，說明這兩城市公園內(nèi)優(yōu)質(zhì)特色群落較少，節(jié)約型城市公園植物群落仍存在較大的發(fā)展空間。在第Ⅰ級的植物群落中選擇不同類型的6個典型群落作為參考模板進(jìn)行了詳細(xì)分析。 在上述調(diào)研和評價結(jié)果的基礎(chǔ)上，針對目前中亞熱帶節(jié)約型城市公園存在的問題，提出：在植物選擇上，應(yīng)以鄉(xiāng)土、節(jié)水性植物為主，，加強(qiáng)苗木產(chǎn)業(yè)開發(fā)；在群落設(shè)計上，要模擬地帶性植物群落特征；在種植技術(shù)上，考慮苗木的間距和栽植季節(jié)；在養(yǎng)護(hù)管理上，大力發(fā)展節(jié)約型植物景觀，實現(xiàn)園林綠化垃圾的循環(huán)利用。同時，總結(jié)提煉出節(jié)地型植物群落、節(jié)水型植物群落和節(jié)材型植物群落的優(yōu)化配置模式，為中亞熱帶節(jié)約型城市公園綠地植物群落構(gòu)建提供科學(xué)依據(jù)和技術(shù)支撐。
[Abstract]:Conservation garden is an important part of the construction of resource-conserving and environment-friendly society, and it is the development direction of urban garden in the future. Plant community, as the only living body in the landscape of green space, plays an important role in the landscape. The optimal construction of plant community can not only create ecological and harmonious living environment for people, but also benefit the development of conservation-oriented society. The main results of this paper are as follows: this study is mainly represented by Ningbo in the eastern coastal area of China and Luzhou in the inland southwest of China, both of which belong to the central subtropical region, but each has its own characteristics. Yinzhou Park, Rihu Park, Yao River Park and Luzhou Zhongshan Park, Binjiang Park and Longduguan Park were studied. Community types and species diversity were investigated and analyzed. The results showed that there were 126 species of seed plants in 30 sample plots in Ningbo, belonging to 97 genera of 55 families, and 136 species of seed plants belonging to 110 genera of 62 families in 30 sample plots of Luzhou. The species composition is mainly native plants, but the higher important value of plant species accounts for only a small proportion, indicating that the plant species in the two places are single and poor. The main type of community is evergreen deciduous broadleaf mixed forest, and the structure of community is simple. Through field investigation and analysis, a reasonable evaluation system was established, and 12 evaluation factors were selected to evaluate 60 typical plant communities by analytic hierarchy process (AHP). The evaluation results showed that the comprehensive evaluation grades of 60 plant communities in Ningbo and Luzhou were mainly concentrated in the second grade, and only a few in the first grade, which indicated that there were few high quality communities in the parks of these two cities. There is still a large space for the development of the plant community in the conservation urban park. Six typical communities of different types were selected as reference templates in class 鈪
