圈層與流動

西安浐灞國家濕地公園位于西安城市東北之隅，灞河入渭河口，用地西南邊界將緊臨城市建設(shè)區(qū)。按自然條件和人為干預程度，由兩河河床向城市建設(shè)方向，設(shè)置4個“圈層遞進”層級，由此構(gòu)成8個濕地類型、20個景觀區(qū)和11個功能區(qū)。河口水流交匯地段具有明顯的方向感，加之季節(jié)性降雨、地勢平坦的特點，以“流動匯集”的理念，構(gòu)成水系、植物群落、道路、人工地形等系統(tǒng)的空間形態(tài)布局，表現(xiàn)了西北半干旱、半濕潤地區(qū)河口型濕地景觀的保育、恢復與營造。

水系和植物

根據(jù)水源規(guī)劃3大水系，灞河取水主要用于恢復區(qū)；未來污水處理廠的中水用于中心人工濕地區(qū)，建設(shè)場地雨水作為補充；渭河取水用于遠期北側(cè)林溪荒地自然恢復區(qū)?？傆盟堪慈曜钌?次換水計算，并設(shè)置枯水期和暴雨期的水系調(diào)控，確保節(jié)約用水。植物群落包含了灘地野生、旱地節(jié)水、田園作物以及城市綠化等群系。結(jié)合不同濕地類型規(guī)劃了9類陸生及濕生種植生境群落，3類水生種植生境群落。

地域自然條件，決定了多樣的“旱濕地”生境營造途徑。建成半年來，時至枯水期，水位下降，灘涂裸露，保育恢復區(qū)水系完整，人工可調(diào)控水系功能初顯。此時植物群落處于生長初期及冬季“荒蕪”期，呈現(xiàn)了這片土地的自然本性。1)

傳統(tǒng)意義的景觀設(shè)計，表現(xiàn)了人們的審美追求在空間外在秩序的表達，是一種征服；自然表現(xiàn)在物種群落依托物質(zhì)生存環(huán)境條件下的自生演替、棲息漂移的規(guī)律，是一種自由。我們致力于尋找表達自然內(nèi)在秩序的景觀營造途徑。（劉暉，徐鼎黃）

The Circle structure and flowing pattern

Chan-ba National Park is located in the northeast corner of Xi'an where the Ba River joins the Wei River. Bordered by urban construction on the south and west sides, the Park has been organized into four "progressive circles"-marking a journey from the nature to the city, eight wetlands areas, 20 scenic areas and 11 functional zones. In response to the area's rainy season, the flat site and its directional bias, the theme of "Flowing and Gathering" was chosen to organize the water systems, plants communities, circulation, topography and "dried" wetland habitats.

Water and planting system

The water system as a whole uses water from three different sources. Water from the Ba River supports the Recovery area; gray-water from the wastewater treatment plant supplies the center and its constructed wetland; water from the Wei River supplies the moorland streams at the north of the site. The water control system was designed for both dry and flood season criteria. At a minimum it is refreshed eight times annually. The planted areas include native, dry land, farm and urban species. There are nine habitat for terrestrial hygrophilous vegetation and three for aquatic vegetation in the park.

The park is weathering its first winter. In this dry season the level of wetland water has decreased in this dry season and the controlled water system is active for the first time.1)

The representation of the nature

王祥見老道所言非虛，一時間有些害怕，急忙問道：“要是真的如道長所言，該如何消弭此劫呢？”他也是看了不少古裝劇，臨時拼湊起的臺詞和老道士倒是很搭調(diào)。

The traditional landscape design, like that of historical gardens, always composed space according to man's aesthetic demands-as a kind of conquest. But nature is about inhabitation, the drift and evolution of species and communities in relation to habitat. It is kind of free. Today we are looking for ways to represent these natural internal orders in landscape design.

評論

鮑威：當人們置身于大尺度景觀規(guī)劃當中，可感知尺度與總圖尺度相距甚遠，這對設(shè)計而言一般是很難把握的。此案在對大尺度自然景觀生態(tài)科學治理的前提下，適當?shù)匾肴斯ぞ坝^，比較成功地將兩個不同尺度與性質(zhì)的設(shè)計有機結(jié)合在一起。景觀建筑元素尤以觀鳥塔曖昧的形式為亮點，人們在自然的超尺度下找到了可以聯(lián)系自身的物體。

闕鎮(zhèn)清：8大類濕地疊加11大功能區(qū)，以水過程聯(lián)系并與兩河及城市開發(fā)區(qū)整合，根據(jù)河口匯流形態(tài)規(guī)律形成自然演替的骨架。自然表達的設(shè)計旨歸，強調(diào)自然生境的保育、恢復和人工營建，遵循最小干擾的宗旨。設(shè)計師依托生態(tài)學知識，做好濕地的醫(yī)生或護理員，剩下的一切交給自然和時間。在城市化快速殺伐自然生態(tài)系統(tǒng)的今天，我們尤其需要更多的自然解放者，而非征服者！

Comments

BAO Wei:When presented with large scale landscape planning, it's always hard to synchronize the scale of human experience with the scale of the master plan.This project successfully integrates these two scales by introducing adequate artificial landscape features on the premise that large scale natural landscape ecology would be well managed. The formal ambiguity of the bird watching tower is the highlight of the project. It helps people find something to relate to in the megascale landscape.

QUE Zhenqing:In this park, eleven major functional areas overlap with eight categories of wetlands connected via water system. According to the principle of minimal interference on nature, the designers focused their efforts on the conservation, restoration and artificial re-construction of natural habitats only. Acknowledged with theories of modern ecology, designers act as good doctors or guardians of the wetlands. Except the eco-restoration design, they just leave the wetlands to live its life through into a landscape. Today, as rapid urbanization is threatening natural ecosystems throughout the nation, we do need many more liberators of nature than conquerors of nature!
