【摘要】：城市湖泊是城市水景環(huán)境,也是休閑游玩和具有吸引力的場(chǎng)所。隨著生活水平的提高,城市對(duì)水景觀的需求越來(lái)越大,在許多公共場(chǎng)所中開發(fā)和修建各類水景觀。在追求湖泊的景觀美和經(jīng)濟(jì)效果最大化的同時(shí),卻忽視了湖體自身生態(tài)系統(tǒng)的構(gòu)建,當(dāng)湖水受到不同程度的污染、湖體的生態(tài)系統(tǒng)遭到破壞時(shí),才考慮對(duì)其治理,往往效果甚微。文章以長(zhǎng)沙市梅溪湖為研究對(duì)象,探討梅溪湖的景觀生態(tài)設(shè)計(jì),意在通過(guò)合理的設(shè)計(jì)和有效的工程措施,形成一個(gè)景觀性和生態(tài)性結(jié)合的可持續(xù)發(fā)展的城市人工湖。文章主要運(yùn)用文獻(xiàn)研究與實(shí)際工程案例相結(jié)合的研究法以及典型案例研究法進(jìn)行研究,在對(duì)梅溪湖進(jìn)行了充分的調(diào)研后,查閱了大量有關(guān)景觀生態(tài)設(shè)計(jì)的理論資料,并通過(guò)分析國(guó)內(nèi)外的典型案例,對(duì)梅溪湖水景觀進(jìn)行生態(tài)設(shè)計(jì)探討,主要分析包括：補(bǔ)換水設(shè)計(jì)、生態(tài)水處理設(shè)計(jì)、濱水植物設(shè)計(jì)、生態(tài)駁岸設(shè)計(jì)。通過(guò)研究,主要的研究成果如下：(1)梅溪湖的多種補(bǔ)換水渠道,如人工濕地、雨水、洪寺庵水庫(kù)、龍王港,通過(guò)雨水的收集凈化系統(tǒng)、湖河聯(lián)通系統(tǒng)、中水回用系統(tǒng)形成梅溪湖的補(bǔ)換水系統(tǒng),有效的保障了水量,有利于水體的流動(dòng),防止水體發(fā)臭水質(zhì)變壞,是本次研究的重點(diǎn)和亮點(diǎn)。(2)梅溪湖的生態(tài)水處理表現(xiàn)在外源污染控制和內(nèi)源污染控制,即控制周邊地區(qū)污水不入湖、對(duì)地表散排雨水處理后入湖、湖底的整治、水生動(dòng)植物系統(tǒng)、水體富營(yíng)養(yǎng)化的處理、控制藻類防止水華、采取富氧措施、在湖底建立復(fù)合式生態(tài)浮床,從各方面入手構(gòu)建立體式的生態(tài)系統(tǒng),同樣也是本次研究的重點(diǎn)和亮點(diǎn)。(3)梅溪湖濱水植物設(shè)計(jì)：根據(jù)駁岸形式和吸引鳥類選擇植物；利用植物本身的高低和植物間的色彩進(jìn)行搭配以及自然式造景選擇植物；在湖底、岸坡和湖面進(jìn)行不同的植物配置,將具有凈化水質(zhì)作用的水生植物與固堤護(hù)岸的耐水濕喬木作為駁岸景觀的重要組成部分,兼顧功能性與觀賞性。(4)梅溪湖生態(tài)駁岸設(shè)計(jì)：采用自然生態(tài)駁岸和人工硬質(zhì)駁岸相結(jié)合的手法,根據(jù)梅溪湖的不同功能分區(qū)進(jìn)行駁岸的選擇。
[Abstract]:The city lake is the city waterscape environment, also is the leisure play and has the attraction place. With the improvement of living standards, the demand for water landscape in cities is increasing, and various kinds of water landscape are developed and built in many public places. While pursuing the beauty of the lake landscape and maximizing the economic effect, it ignores the construction of the lake body's own ecosystem. When the lake water is polluted to varying degrees and the lake's ecosystem is destroyed, the lake body's ecosystem is only considered to be treated. Often it has little effect. Taking Meexi Lake in Changsha City as the research object, this paper discusses the landscape ecological design of Meexi Lake, which aims to form a sustainable urban artificial lake with the combination of landscape and ecology through reasonable design and effective engineering measures. This paper mainly uses the research method of combining the literature research with the actual engineering cases and the typical case study method to carry on the research, after carrying on the thorough investigation to the Meixi Lake, has consulted the massive related landscape ecology design theory data. Based on the analysis of typical cases at home and abroad, the ecological design of Meexi Lake landscape is discussed, including the design of water replacement, the design of ecological water treatment, the design of waterfront plants and the design of ecological barge. Through the research, the main research results are as follows: (1) many water replacement channels in Meexi Lake, such as artificial wetland, Rain Water, Hongsian Reservoir, Longwang Port, through the collection and purification system of Rain Water, Lake and River Connectivity system, The reclaimed water reuse system forms a rehydration system in Meexi Lake, which effectively guarantees the amount of water, is conducive to the flow of water bodies, and prevents the deterioration of the stinking water quality of the water bodies. (2) the ecological water treatment of Meexi Lake is manifested in exogenous pollution control and internal pollution control, that is, the control of sewage not entering the lake in the surrounding area, the treatment of surface Rain Water into the lake, and the regulation of the lake bottom. Aquatic flora and fauna system, treatment of eutrophication of water body, control of algae to prevent Shui Hua, oxygen enrichment measures, establishment of compound ecological floating bed in lake bottom, construction of three-dimensional ecosystem from all aspects, It is also the focus and bright spot of this study. (3) the waterfront plant design of Meixi Lake: according to the form of the barge and the attraction of birds, the plants are chosen according to the form of the barge; the plants are matched by the height of the plant itself and the color among the plants, and the natural landscape is chosen; at the bottom of the lake, With different plant configurations on bank slopes and lakes, aquatic plants with the function of purifying water quality and water and moisture tolerant trees of embankment revetment are taken as an important part of the barge landscape. (4) the design of ecological barge in Meexi Lake: adopting the combination of natural ecological barge and artificial hard barge, according to the different functional zones of Meexi Lake, the selection of the barge was carried out.
