【摘要】：城市在現(xiàn)代人類(lèi)群居生活中處于核心地位,隨著人口增長(zhǎng)與城市化進(jìn)程的加快,圍繞城市開(kāi)展的擴(kuò)建,改建,新建等項(xiàng)目不斷增加,這些項(xiàng)目在滿(mǎn)足人類(lèi)需求的同時(shí)給環(huán)境帶來(lái)了破壞,人地矛盾越發(fā)明顯�；诖�,建設(shè)強(qiáng)調(diào)人與自然和諧相處的生態(tài)城市勢(shì)在必行。本文以緩和人地矛盾為出發(fā)點(diǎn),在建立城市生態(tài)系統(tǒng)評(píng)價(jià)模型的基礎(chǔ)上,分析了銀川城市生態(tài)系統(tǒng)的自然、經(jīng)濟(jì)和社會(huì)三大子系統(tǒng)的特點(diǎn),分別從空間、能源、固廢循環(huán)、水資源、生物生境、公共設(shè)施和交通7個(gè)方面對(duì)三大系統(tǒng)的影響進(jìn)行了評(píng)價(jià)。結(jié)果表明:銀川城市生態(tài)系統(tǒng)處于基本可持續(xù)發(fā)展的水平,三大子系統(tǒng)協(xié)調(diào)程度為一般協(xié)調(diào),但市域土地資源和水資源的人口承載極限值為430萬(wàn)人,中心城區(qū)交通承載車(chē)輛極值為115萬(wàn)輛。此外,在分析本地生態(tài)系統(tǒng)的同時(shí)亦深化認(rèn)識(shí)了我國(guó)西北地區(qū)的生態(tài)環(huán)境狀況,可為具備相似條件的其他城市解決生態(tài)環(huán)境問(wèn)題提供指導(dǎo)意見(jiàn)。銀川市生態(tài)基礎(chǔ)較為薄弱,城市生態(tài)系統(tǒng)處于基本可持續(xù)發(fā)展的水平,應(yīng)該從集約空間、大力發(fā)展綠色交通、保護(hù)水資源和水環(huán)境、保護(hù)生物生境、開(kāi)發(fā)利用新能源,轉(zhuǎn)變能源結(jié)構(gòu)等方面來(lái)進(jìn)行生態(tài)城市建設(shè),以確保城市生態(tài)系統(tǒng)的穩(wěn)定與平衡。
[Abstract]:Cities are at the core of modern human social life. With the rapid development of population and urbanization, the expansion, reconstruction and construction of cities are increasing. These projects not only meet the needs of human beings, but also damage the environment, and the contradiction between human and land becomes more and more obvious. Based on this, it is imperative to build an ecological city that emphasizes harmony between man and nature. On the basis of establishing the evaluation model of urban ecosystem, this paper analyzes the characteristics of the natural, economic and social subsystems of the urban ecosystem in Yinchuan from the aspects of space, energy, solid and waste recycling. The impacts of the three systems were evaluated from seven aspects: water resources, biological habitats, public facilities and transportation. The results show that the urban ecosystem of Yinchuan is in the level of basic sustainable development, the coordination degree of the three subsystems is general coordination, but the population carrying limit value of urban land resources and water resources is 4.3 million people. The extreme value of traffic carrying vehicles in central urban area is 1.15 million. In addition, the analysis of the local ecosystem also deepened the understanding of the ecological environment in Northwest China, which can provide guidance for other cities with similar conditions to solve the ecological environment problems. The ecological foundation of Yinchuan City is relatively weak, and the urban ecosystem is at the level of basic sustainable development. Therefore, it is necessary to develop green traffic, protect water resources and water environment, protect biological habitats, and develop and utilize new energy from intensive space. In order to ensure the stability and balance of urban ecosystem, the construction of ecological city should be carried out by transforming energy structure.
