位于南京城市郊区的一片棕地通过举办园林博览会而被修复，并在展会后转变为一个旅游度假区。项目基址为这片棕地中的一个大型采石坑，规划为拥有酒店、植物园、餐厅、咖啡、室外剧场等的以再生采石场为主题的旅游综合体。项目的挑战不仅来自于采石坑被严重破坏的自然环境，还来自于项目功能和目标的复杂性。针对采石场不同部分的地质条件和景观特征，采取了不同的修复方式，创造新景观的同时保留了场地历史的记忆。在研究了场地的日照、通风、排水等条件的基础上，设计团队选择了800多种植物形成了12个主题植物区，展现了生态修复的可能性和植物多样性，为公众自然教育提供了机会。它提供了多种复合功能，将消极荒芜的矿坑转变为充满活力的旅游度假综合体，创造了极高的生态价值、经济价值、社会价值。
A brownfield on the outskirts of Nanjing wasrestored by convening a garden exposition and thereafter istransforming into a tourist resort. The project is located in alarge quarry of the brownfield and is planned to be a tourist complex themed byregenerated quarries, which includes a hotel, botanical garden, restaurant, café andoutdoor theater. The project faced challenges not only from the severelydamaged natural environment of the quarry, but also from the complexity of theproject's functions and goals. The proposal adopts differentiated restoration approaches inconsideration of the geological conditions and landscape characteristics ofdifferent parts of the quarry, creating a new landscape while retaining the memory of the site's history. On the basis ofresearching conditions onsite like sunlight, ventilation and drainage, the designteam chose more than 800 species of plants to form 12 thematic plant areas,which showcases the eco-restoration possibility and plant diversity andprovides an opportunity of natural education for the public. It alsoprovides a variety ofcomplex functions to transform a negatively barren quarry pit into a vibrant tourist resort complex, creating high ecological, economic and social value.
汤山地区拥有优质的温泉，在1500年前就是皇家的温泉疗养地，古迹、温泉和良好的自然环境使其今日仍然是南京城市郊区的一个度假地。不过，20世纪60年代，地区北部的一些石灰岩山体被开采作为水泥制造原料，水泥厂也在山脚建造。到2018年，南京市政府决定关闭这些采石场和水泥厂，通过举办园林博览会，修复自然环境，改造工业设施，建造舒适的旅游服务设施，将这片棕地转变为旅游度假区。
The Tangshan area, provided with its naturalpremium hot springs, was a royal spa 1,500 years ago. Today, it remains aresort on the outskirts of Nanjing today due to its monuments, hot springs andgood natural environment. Nevertheless, in the 1960s, some limestone hills inthe northern part of the region were mined as raw material for cement, as aresult plenty of cement plants were built at the foot of the hills. By 2018,the Nanjing government decided to close these quarries and cement plants andtransform this brownfield into a tourist resort by restoring the naturalenvironment, regenerating industrial facilities,building comfortable touristfacilities andhosting the garden exposition.
场地在此次规划的园博园范围内，位于半山腰上，曾经是南京最大的采石坑，长1100m，有两层，深度10-22米，总面积达25.5公顷。
The site that lies on a hillside within the planned garden expoused to be the largest quarry in Nanjing, 1,100m long and 10-22m deep, with twolevels, covering a total area of 19.6 hectares.
业主希望未来花园能够不仅仅是园博会的一个展区，满足园林园艺展览的需求，还需要具有持久的魅力和商业运营的可能，在会后成为有吸引力的旅游目的地。于是，这里被规划成含矿坑主题酒店、植物园、餐厅、咖啡、室外剧场等为一体的以再生采石场为主题的旅游综合体。
The client hoped Future Garden to be more than just a show place meeting the needs of exhibition, but also to own lasting charm and the possibility of commercial operation, becoming an attractive tourist destination after the expo. It was therefore planned as a tourism complex themed by regenerated quarries, which includes hotel, botanical garden, restaurant, café and outdoor theater.
项目的挑战不仅仅来自于采石坑本身被严重破坏的自然环境，还来自于项目功能和目标的复杂性。矿坑的东侧是酒店，紧邻酒店是是一个大型室外剧场，夜晚这里会举办以悬崖为背景的舞台演出和灯光秀。底层的采石坑被规划为观赏植物和美丽的鱼的空间。矿坑北侧边缘朝向园博园和朝向矿坑内部设计了几个观景平台。一系列台阶、坡道和自动扶梯连接矿坑内外不同的层级。景观设计一方面要修复矿坑，创造有特色的景观，成为旅游度假区有吸引力的景点；另一方面，要满足建筑复杂的消防、人流集散、设备安装等的要求，并将不同类型的建筑融合在景观中。
The project faced with challenges not only from the severely damaged natural environment of the quarry, but also from the complexity of project's functions and goals. To the east of the quarry is a hotel, and adjacent to the hotel lies a grand outdoor theater hosting stage performances and light shows at night with cliff as a backdrop. The bottom of the quarry is planned as a space for ornamental plants and beautiful fish. Several viewing platforms are arranged on the northern edge of the pit towards the main area of the expo and the interior of the quarry respectively. A series of steps, ramps and escalators connect different levels inside and outside. The proposal aims to restore the quarry and create a characteristic landscape that would become an attraction of the resort area on the one hand. On the other, it is to meet the complex requirements of the buildings for fire fighting, flow gathering and circulation and equipment installation, meanwhile to integrate different types of buildings in the landscape.
植物园是项目的核心，位于底层采石坑的西侧，北侧紧邻崖壁有一组2层的商业建筑，包含咖啡、餐厅、展览等功能。为了创造梦幻的效果，建筑师将植物园屋顶设计成一个巨型的透明水池，用42根高大的不锈钢树状结构柱支撑，阳光穿过水面和透明屋顶洒在植物园中，映照出一片生机勃勃的绿色世界。
As the core of the project, botanical garden islocated on the west side of the bottom quarry, with a set of 2-story commercialbuildings adjacent to cliff, functioning as café,restaurant, and exhibition. To create a dreamy atmosphere, architects designedthe roof of the botanical garden as a giant transparent pool, supported by 42tall stainless steel tree-like structural columns, with sunlight pouring inthrough the water and the transparent roof to irradiate a vibrant green world.
通过对光照条件、水分条件和覆土可行性的分析，确定了植物园从西到东分为旱生、中生和湿生3个不同的生境区。
The botanical garden is classified as threedifferent habitat zones from west to east namely, arid area, mesic area andhumid area through the analysis of sunlight conditions, moisture conditions andearthing feasibility.
光照条件好的岩坡上是旱生花园，同时也是植物园的主入口，有8、9m的高差，需要提供台阶和无障碍坡道。层叠错落的岩石台地，将67级台阶和总长86m的之字形坡道巧妙地结合，台地上生长着形态色彩各异的耐旱和耐贫瘠植物。
As the main entrance of botanical garden, aridgarden lies on rocky slope with good sunlightconditions. A height difference of 8m requires steps and ramps to be provided.The rocky terraces combine 67 steps and an 86m-long zigzag ramp, on whichvarious drought- and barren-tolerant plants grow.
中生花园的设计，通过创造起伏的丘陵、幽深的峡谷、陡峭的岩石，产生了丰富的空间变化，为不同植物创造了合适的生长环境。在复杂的地形中，包含了多个主题的植物展示区，如药用植物，芳香和蜜源植物，孑遗植物、茶饮植物、奇趣植物等的区域，以及以不同色彩为主题的花园区。为了增加植物的种类和观赏性，还设计有2个小型的暖房，为不能露地过冬的沙漠植物和气生植物提供庇护。一座蜿蜒的空中栈桥连接了商业建筑二层与花园中的假山和观景平台，提供了在树梢穿越的独特体验和俯瞰花园的视角。
The mesic garden is proposed to create rich spatialvariations by shaping undulating landform, deep ravines and steep rocks, offeringthe suitable environment for different plants to grow. In the complextopography there are several thematic plant display areas, such as areasseparately for medicinal plants, aromatic and nectariferous plant, relict plant,tea plants, fantastic plants and plants with different colors. To increase thevariety and attraction, 2 small green houses are designed to provide shelterfor desert plants and aerophytes that cannot toleratethe winter outdoor. A winding skywalk connects the second floor of commercialbuilding to the rockery and viewing platform in the garden, providing a uniqueexperience of traversing through treetops and overlooking the garden scenery.
湿生花园地势较低，光照条件较差，雨水和岩石渗水会顺应地势流到最低处。湿生花园包含了两部分，一部分是种植水生植物的水光潋滟的池塘，有栈桥穿越茂盛的水生植物丛；另一部分是作为荫生植物区的下凹区，顺应地形的层层台地和之字形坡道引导游客进入花园的最低处。台地和坡道边有一条窄窄的石质水渠，水渠底的纹理将水流激荡出小小的水花和潺潺的水流声。水渠一会儿在路左，一会儿在路右，一会儿穿越道路，一会儿潜入花丛。在不同层级的台地边缘，水从石槽上跌落，落入小水池，呈现闪亮的小瀑布，留下悦耳的水声，然后又沿着下层的水渠继续流淌，最终汇入最低处的水池。每一层台地上和坡道边缘，都生长着大量苍翠润泽的耐湿和荫生植物。水渠、跌水和水池不仅创造了丰富的景观，也增加了环境湿度，为植物的生长创造了更好的条件。
With low-lying position, humid garden has poorsunlight condition, rainwater and water seepage from the rock flow down alongthe terrain. The garden consists of two parts: the glistening pond with awinding bridge through the lush aquatic flora; and the sunken space as shady plant area, with terraces and a zigzagramp leading visitors to the lowest part of the garden. There is a narrow stonecanal by the side of terraces and ramp, the texture of canal bottom causes small splashes and gurgles of water.The canal runs along or across the ramp, and dives into the flowers. At the edge of theterraces, water drops from the stone troughs into small ponds, presenting small shimmering cascades and leaving pleasant sound, and then continues toflow along the lower canal, eventually joining the lowest pond. On each level of the terrace and on the edge ofthe ramp are grown many hygrophilous and shady plants. The canals, cascades and ponds not only produce rich landscape, but alsoincrease the humidity and create better conditions for plants.
一种名为“植物泡泡”的微型装置被特意设计，不仅可以为一些不耐寒的植物提供气候保护，也可以为一些小型植物提供一个单独展示的机会，还可以作为青少年栽植DIY的种植池，为植物园未来的公众教育和商业运营提供
