【摘要】：城市绿地规划是整个城市绿化的关键,是决定城市发展与进步的重要标志。合理的绿地规划有助于城市的可持续发展。为了给城市规划提供了实际范例。本研究选取了陕西省勉县城区作为规划对象,对其地区背景和绿地现状进行了分析,确定规划范围和规模,并从公园绿地,生产绿地,防护绿地,附属绿地及其他绿地五方面对勉县城区进行层次规划;同时对勉县地区树种配置从基调树种、骨干树种和一般树种进行了配置;并对植物多样性开发和保护工作提出了参考措施,结果如下:1、勉县城区分类规划为:a、公园绿地,其中综合公园33.62 hm2,次综合公园20 hm2,专类公园71 hm2,带状绿地189.27 hm2,街旁绿地78.53 hm2;b、生产绿地59.75 hm2;c、防护绿地726.12 hm2;d、附属绿地,其中居住绿地502.3 hm2,工业绿地、仓储绿地、对外交通绿地和道路绿地绿地率均不小于30%;e、其他绿地2742.1 hm2。规划后的绿地总面积增加了80倍以上,绿地率和人均绿地均增加了8倍以上。2、树种规划为:a、基调树种,包括桂花、紫叶李、垂柳、香樟等16个树种;b、骨干树种,包括旱莲、国槐、三角枫、香樟等15个树种;c、县树县花,县树选择旱莲、桂花或水杉,县花选择桂花、含笑。从植物多样性的角度出发,按照“适地适树”原则重点培育、发展有生态和观赏价值的野生乡土树种,促进园林植物的多样化。加强区域生物多样性、城市公园及绿地系统生物多样性、珍稀物种迁地保护和园林植物引种驯化工作。
[Abstract]:City green space planning is the key of city greening, is an important symbol of city development and progress of the sustainable development. Reasonable landscape planning contributes to the city. In order to provide a practical example for city planning. This study selected the Shaanxi province Mianxian city as the object of its planning, regional background and status of green space were analyzed. Determine the planning scope and scale, and from the park, the production of green space, protection green land, attached green space and other green space planning in five aspects of Mianxian city; at the same time in the Mianxian area tree configuration from the tone of tree species, main species and common species were configuration; and put forward measures for reference, work on plant diversity protection and development the results are as follows: 1, Mianxian city planning classification: A, park green space, including 33.62 hm2 Park, comprehensive park theme park 20 Hm2, 71 Hm2, 189.27 hm2 green belt, Roadside green space 78.53 hm2; B, C, hm2 59.75 production of green space; protective green 726.12 hm2; D, the attached green space, residential green space 502.3 Hm2, industrial green, green warehousing, transportation and road green green green rate of not less than 30% e, 2742.1 hm2.; other green space planning of the total area of green space increased more than 80 times, and the per capita green green rate increased more than 8 times.2, tree species planning: A, tone species, including sweet scented osmanthus, purple leaf plum, willow, camphor and other 16 species; B, the backbone of tree species, including Eclipta, Sophora japonica, maple, camphor and other 15 species; C tree, county county flower, tree osmanthus or Eclipta County, metasequoia, county flower selection of sweet scented osmanthus, smiling. Starting from the perspective of plant diversity, in accordance with the "proper tree" principle, focus on fostering the development of ecological and ornamental value of wild native species, to promote a variety of garden plants. To strengthen the regional biodiversity, city parks and The biodiversity of the green system, the ex situ conservation of rare species and the introduction and domestication of garden plants.
