【摘要】：我國正處在城市化進(jìn)程的加速階段,城市規(guī)模迅速擴(kuò)大,人口急劇增長；城市周邊耕地流失嚴(yán)重,破壞農(nóng)村正常社會(huì)結(jié)構(gòu),損害鄉(xiāng)村發(fā)展；城市生態(tài)環(huán)境持續(xù)惡化,自然基底不斷萎縮。種種“城市病”愈演愈烈,已嚴(yán)重威脅到城市的生存和發(fā)展。傳統(tǒng)綠化隔離帶單純隔離保護(hù)的方式已無法滿足城市發(fā)展的多種需求,不斷遭到建設(shè)用地蠶食肢解,“破窗效益”日益明顯：而“城市生態(tài)隔離區(qū)綠化體系”作為控制城市空間格局,改善城市生態(tài)環(huán)境,提供郊野娛樂空間,傳承地方文脈,統(tǒng)籌區(qū)域協(xié)調(diào)發(fā)展以及構(gòu)建城市生態(tài)景觀格局的重要空間結(jié)構(gòu),正受到越來越多的關(guān)注。通過采取差異化的空間策略,以生態(tài)適宜性分析為支撐,結(jié)合現(xiàn)有生態(tài)資源,在適宜區(qū)域引入生態(tài)產(chǎn)業(yè),在改善隔離區(qū)環(huán)境質(zhì)量的同時(shí)提升農(nóng)民收入,讓他們成為維護(hù)生態(tài)隔離區(qū)綠化體系的主要力量。通過這種方式能夠真正讓生態(tài)隔離區(qū)綠化體系落到實(shí)處,并得到有效保護(hù),從而實(shí)現(xiàn)生態(tài)隔離區(qū)自然、社會(huì)、經(jīng)濟(jì)的可持續(xù)發(fā)展。本文首先對國內(nèi)外生態(tài)隔離區(qū)綠化體系構(gòu)建理論與實(shí)踐進(jìn)行了分析研究,據(jù)此歸納總結(jié)出生態(tài)隔離區(qū)綠化體系構(gòu)建時(shí)應(yīng)予以格外關(guān)注的8個(gè)要點(diǎn)。通過SWOT分析明確玉符河自身的優(yōu)勢與不足,以及機(jī)遇與挑戰(zhàn)。此后,作者通過德爾菲法選取了坡度、坡向、水域緩沖區(qū)、植被類型、干擾強(qiáng)度及交通設(shè)施緩沖區(qū)6個(gè)主要的生態(tài)影響因子,并對其進(jìn)行評價(jià)分級,在此基礎(chǔ)上逐一對各個(gè)因子進(jìn)行單因子適宜性分析,得到每個(gè)因子的適宜性區(qū)劃圖。然后構(gòu)造判斷矩陣,利用層次分析法確定了6個(gè)因子的權(quán)重。此后,再利用GIS技術(shù)進(jìn)行生態(tài)適宜性綜合評價(jià),通過空間加權(quán)疊加運(yùn)算及重分類,劃定出禁止建設(shè)區(qū)、嚴(yán)格限建區(qū)、一般限建區(qū)以及適宜建設(shè)區(qū),得到玉符河生態(tài)隔離區(qū)綠化體系的綜合生態(tài)適宜性區(qū)劃圖。以該區(qū)劃圖為基礎(chǔ),作者運(yùn)用“斑塊-廊道-基質(zhì)”模型構(gòu)建了分層級的景觀生態(tài)格局,旨在保證各項(xiàng)生態(tài)過程的完整高效。通過綠化體系將生態(tài)隔離區(qū)內(nèi)的建設(shè)用地規(guī)模控制在總用地的15%以內(nèi),保證隔離區(qū)的生態(tài)屬性和綠色屬性,避免人類活動(dòng)對生態(tài)核心區(qū)的干擾。最后,在文獻(xiàn)資料查閱及實(shí)地調(diào)研的基礎(chǔ)上,結(jié)合生態(tài)適宜性分析成果及總體規(guī)劃、水生態(tài)文明建設(shè)規(guī)劃、綠地系統(tǒng)規(guī)劃等上位規(guī)劃要求,針對玉符河生態(tài)隔離區(qū)功能定位及當(dāng)前存在的問題,深入挖掘地方精神、鄉(xiāng)土景觀,分區(qū)段提出玉符河生態(tài)隔離區(qū)綠化體系的景觀風(fēng)貌規(guī)劃及建議。并在適宜地區(qū)引入相應(yīng)的活動(dòng)及產(chǎn)業(yè)類型,以促進(jìn)生態(tài)隔離區(qū)生態(tài)、景觀、文化、休閑及經(jīng)濟(jì)功能的和諧共生。
[Abstract]:Our country is in the acceleration stage of urbanization, the city scale expands rapidly, the population increases rapidly, the cultivated land around the city loses seriously, destroys the normal social structure of the countryside, damages the rural development, the urban ecological environment continues to deteriorate, The natural base shrinks. Various "urban diseases" become more and more serious, which have seriously threatened the survival and development of cities. The traditional way of isolation and protection in the green isolation belt has been unable to meet the various needs of urban development, and has been continuously eroded and dismembered by construction land. The benefit of breaking windows is becoming more and more obvious: the greening system of urban ecological isolation area is used to control the urban spatial pattern, to improve the urban ecological environment, to provide recreational space for the countryside, and to pass on the local context. More and more attention is being paid to coordinating the regional development and constructing the important spatial structure of urban ecological landscape pattern. Through adopting the spatial strategy of differentiation, taking the ecological suitability analysis as the support, combining the existing ecological resources, introducing ecological industry in the suitable area, improving the environmental quality of the isolated area and raising the farmers' income, Let them become the main force to maintain the green system of the ecological separation area. Through this way, the greening system of the ecological separation area can be implemented and effectively protected, thus realizing the sustainable development of nature, society and economy in the ecological separation area. In this paper, firstly, the theory and practice of the construction of greening system in the ecological isolation area at home and abroad are analyzed and studied, and the eight key points which should be paid special attention to when constructing the greening system in the ecological separation area are summarized. Through SWOT analysis, the advantages and disadvantages of Yufu River, as well as opportunities and challenges are identified. After that, the author selected six main ecological influence factors by Delphi method, such as slope, slope direction, water buffer, vegetation type, interference intensity and traffic facility buffer zone, and evaluated the ecological influence factors of slope, slope direction, water buffer area, vegetation type, traffic facility buffer zone and so on. On this basis, the suitability of each factor is analyzed one by one, and the suitability zoning diagram of each factor is obtained. Then the judgment matrix is constructed, and the weight of the six factors is determined by the analytic hierarchy process (AHP). After that, the comprehensive evaluation of ecological suitability is carried out by using GIS technology, and through space weighted superposition operation and re-classification, the forbidden construction area, strictly limited construction area, general restricted construction area and suitable construction area are determined. The comprehensive ecological suitability zoning map of the greening system in the ecological separation area of Yufu River was obtained. Based on the zoning map, the author constructed a hierarchical landscape ecological pattern by using the "patch, corridor and matrix" model in order to ensure the integrity and efficiency of each ecological process. The scale of the construction land in the ecological separation area is controlled within 15% of the total land through the greening system to ensure the ecological attribute and the green attribute of the separation area and to avoid the interference of human activities to the ecological core area. Finally, on the basis of literature review and field investigation, combined with ecological suitability analysis results and overall planning, water ecological civilization construction planning, green space system planning and other upper planning requirements, In view of the function orientation of Yufu River ecological separation area and the existing problems, this paper deeply excavates the local spirit, the local landscape, and puts forward the landscape planning and suggestions for the greening system of the Yufu River ecological separation area. In order to promote the harmonious symbiosis of ecological landscape culture leisure and economic function the corresponding activities and industrial types are introduced in the suitable areas.
