【摘要】：南京市江蘇軟件園研究范圍處于吉山基地、東大山、板霞路和文化創(chuàng)意產(chǎn)業(yè)園之間,面積約10 hm2,規(guī)劃定位為生態(tài)型新興產(chǎn)業(yè)示范區(qū)。對其規(guī)劃進(jìn)行生態(tài)評價(jià)和探索生態(tài)廊道的優(yōu)化策略有助于在軟件園的全面開發(fā)建設(shè)形成之前利用生態(tài)評估為城市新興發(fā)展的高新技術(shù)園區(qū)提供城市空間層面的指導(dǎo),也有利于促進(jìn)園區(qū)基底生物群落的保護(hù)和生態(tài)修復(fù)。主要從三個(gè)層面著手:一是景觀格局,二是城市通風(fēng)道優(yōu)化規(guī)劃,三是生態(tài)廊道優(yōu)化規(guī)劃。這三個(gè)層面的評價(jià)和優(yōu)化研究有內(nèi)在聯(lián)系:對景觀格局的評價(jià)有利于對城市空間布局進(jìn)行量化評價(jià),而對城市空間布局的分析是城市通風(fēng)道和生態(tài)廊道優(yōu)化規(guī)劃的基礎(chǔ)。城市通風(fēng)道和城市生態(tài)廊道的優(yōu)化策略能對規(guī)劃現(xiàn)狀存在的不利因素進(jìn)行優(yōu)化調(diào)整,對城市規(guī)劃進(jìn)行生態(tài)評價(jià)有利于緩解人地矛盾:城市通風(fēng)道的優(yōu)化規(guī)劃有利于緩解城市發(fā)展與氣候之間的矛盾,而生態(tài)廊道的優(yōu)化規(guī)劃則有利于緩解城市發(fā)展與生物生存發(fā)展之間的矛盾。本文通過對南京市江蘇軟件園地塊的規(guī)劃圖件提取用地分類,將其利用ArcGIS軟件并結(jié)合園區(qū)內(nèi)的建筑高度、建筑密度以及周邊重要的生態(tài)點(diǎn)等信息建立園區(qū)的地理信息數(shù)據(jù)庫,并在此基礎(chǔ)上展開分析,得出景觀格局的優(yōu)化建議、城市潛在通風(fēng)道的定位、城市氣候功能分區(qū)及優(yōu)化建議、生態(tài)廊道的定位、基底植物群落的評價(jià)及優(yōu)化建議。對江蘇軟件園規(guī)劃的主要評價(jià)如下:(1)相比于自然風(fēng)景區(qū)等景觀區(qū)域,研究地塊的景觀多樣性不高,用地類型之間的比重差異較大、景觀不均衡;占比例最大的是微型斑塊和小型斑塊,大中型斑塊較少。(2)研究地塊在冬季西北風(fēng)狀況下通風(fēng)狀況較好,依托西北部的山體、丘陵自然形成的風(fēng)壓差和熱壓差可緩解城市熱島效應(yīng),但在夏季東南風(fēng)狀況下由于地塊南端建筑密度較大,缺乏大面積的自然綠地,需要規(guī)劃城市通風(fēng)道,對空氣流進(jìn)行疏導(dǎo)。(3)研究地塊內(nèi)部的植物群落整體來看尚不具備自然聯(lián)系成生物廊道的潛力,部分?jǐn)嗔腰c(diǎn)生境破碎化不利于生物遷移和繁衍,亟待科學(xué)的規(guī)劃和引導(dǎo)。對江蘇軟件園規(guī)劃的優(yōu)化建議如下:(1)放緩城市擴(kuò)張速度,規(guī)劃先行。針對江蘇軟件園的待建地,應(yīng)當(dāng)對規(guī)劃生態(tài)評價(jià)中預(yù)見的可能出現(xiàn)的生態(tài)問題早發(fā)現(xiàn)早整治,盡量在下一步建設(shè)造成更大的破壞前先采取生態(tài)修復(fù)措施;同時(shí)對規(guī)劃評價(jià)中選定的潛在城市通風(fēng)道和潛在生物廊道選址進(jìn)行保護(hù)和修復(fù)建設(shè),作為城市建設(shè)過程中的生態(tài)基礎(chǔ)設(shè)施建設(shè);根據(jù)城市通風(fēng)道和潛在生物廊道的定位,可對下一步建設(shè)的做出相應(yīng)的調(diào)整。(2)促進(jìn)大中型綠地保護(hù)和建設(shè)。規(guī)劃中預(yù)留的大中型綠地空間應(yīng)謹(jǐn)慎使用,保證綠化覆蓋率和綠化層次同時(shí)在植物配置時(shí)注意增加鄉(xiāng)土植物和掛果植物的應(yīng)用;對現(xiàn)狀生態(tài)狀況較好近自然綠地的邊緣大塊綠地,在規(guī)劃過程中應(yīng)盡量較少人為干擾;對外圍原有的重要生境斑塊的地形地貌和群落結(jié)構(gòu)都要最大限度進(jìn)行保護(hù)。(3)控制建筑高度和密度。在建設(shè)推進(jìn)之前,應(yīng)對尚未建設(shè)的建筑景觀進(jìn)行重新評估:水平結(jié)構(gòu)上,應(yīng)合理控制建筑密度,有效地使空間分割轉(zhuǎn)變?yōu)榭臻g的鑲嵌,擴(kuò)大有利于氣體環(huán)流的空間;垂直結(jié)構(gòu)上,宜將高層建筑與低層建筑有機(jī)結(jié)合。除此之外,還可在以下幾個(gè)方面采取措施:選擇熱容較小的表面材料以緩解熱污染;控制污染源以緩解空氣污染問題。(4)發(fā)揮城市開放空間和水體的生態(tài)作用,應(yīng)在城市開放空間和水體構(gòu)建相對復(fù)雜的園林植物群落。水平結(jié)構(gòu)上,應(yīng)增加物種多樣性,增強(qiáng)生態(tài)群落的穩(wěn)定性;垂直結(jié)構(gòu)上,應(yīng)喬、灌、草結(jié)合提高豐富度,發(fā)揮不同生活型植物的生態(tài)功能。
[Abstract]:The research scope of the Jiangsu Software Park in Nanjing is located in Jiashan base, East Dashan, Zan Xia Road and Cultural Creative Industrial Park, with an area of about 10 hm2. The planning is located as an ecotype new industry demonstration area. The ecological evaluation of its planning and the exploration of the optimization strategy of ecological corridor are helpful for the use of ecology before the development and construction of the software garden. The assessment provides guidance for the urban space level for the new and new high-tech parks of the city, and also helps to promote the protection and ecological restoration of the base biological community of the park. It mainly starts from three aspects: one is the landscape pattern, the two is the optimization of the urban ventilator, and the three is the optimization of the ecological corridor. The evaluation and optimization of the three levels The evaluation of landscape pattern is beneficial to the quantitative evaluation of urban spatial distribution, and the analysis of urban spatial layout is the basis for the optimization of urban ventilation channel and ecological corridor. The optimization strategy of urban ventilation Road and urban ecological corridor can optimize and adjust the disadvantages of the planning situation, to the city. The ecological evaluation of planning is beneficial to mitigate the contradiction between people and land: the optimization of urban ventilation path is beneficial to alleviate the contradiction between urban development and climate, and the optimization of ecological corridor is beneficial to alleviate the contradiction between urban development and biological survival and development. This paper extracts the planning drawings of the software Park in Jiangsu, Nanjing. By means of land classification, the geographic information database of the park is established by using the ArcGIS software and combining the building height, the building density and the important ecological points in the surrounding area. On this basis, the analysis is carried out to get the optimal suggestion of the landscape pattern, the location of the potential ventilation channel in the city, the urban climate function zoning and the optimization suggestions. The location of the corridor and the evaluation and optimization of the basilar plant community. The main evaluation of the planning of the Jiangsu software park is as follows: (1) compared to the natural landscape area, the landscape diversity of the plots is not high, the proportion of the land types is different, the landscape is not balanced; the largest proportion is the miniature patches and small patches, and the large and middle scale There are few types of patches. (2) the ventilation condition of the study block is better under the northwest wind in winter. Relying on the northwest of the mountain, the wind pressure difference and the hot pressure difference can relieve the urban heat island effect, but in the summer east wind condition, because of the large density of the south end of the block and the lack of large area of natural green space, the urban ventilation channel is needed. Air flow is dredging. (3) the study of the plant community in the interior of the block does not have the potential for natural links to be a biological corridor, and the fragmentation of some sites is not conducive to biological migration and reproduction, and the planning and guidance of the Jiangsu software park are urgently needed. (1) slow down the speed of urban expansion. In view of the Jiangsu software garden, we should find early regulation on the possible ecological problems foreseen in the planning ecological evaluation, and try to take ecological restoration measures before the next step of the construction to cause greater damage; at the same time, the potential urban ventilation path and the potential biological corridor location selected in the planning evaluation are protected and repaired. The construction of the ecological infrastructure in the process of urban construction; according to the location of the urban ventilation Road and the potential biological corridor, we can make the corresponding adjustment to the next step. (2) promote the protection and construction of large and medium-sized green space. The large and medium-sized green space reserved in the plan should be used carefully to ensure the greening coverage and the greening level. At the time of plant allocation, attention should be paid to increasing the application of native plants and fruit plants, and there should be less human interference in the planning process for the large green areas with better ecological conditions near the natural green space; the topographic landforms and community structure of the important surrounding habitats should be protected to the maximum extent. (3) control the height of the building. And density. Before the construction is promoted, we should reevaluate the architectural landscape that has not been constructed: the level structure should reasonably control the density of the building, effectively make the space division into space inlay, and expand the space for the circulation of the gas; in the vertical structure, it should combine the high level building with the low level building. In addition, it is also available. The following measures are taken: select the surface material with small heat capacity to alleviate the heat pollution; control the source of pollution to alleviate the air pollution problem. (4) to play the ecological role of the urban open space and water body, the relatively complex garden plant community should be constructed in the urban open space and water body. On the vertical structure, we should increase the richness of trees and plants, and give play to the ecological functions of different life forms.
