Ecological Restoration: A Movement to Improve Chinese Cities and Realize the Beautiful China Dream
By Kongjian Yu
在中國,當(dāng)某種全國性、系統(tǒng)性且與人民生活密切相關(guān)的不良狀態(tài)發(fā)生時(shí),似乎都需要通過一場(chǎng)全民性的、自上而下的行動(dòng),即“運(yùn)動(dòng)”來迅速解決或制止某種錯(cuò)誤行為的蔓延。而離開中國的城鄉(xiāng)現(xiàn)實(shí)背景,我們則難以理解 “海綿城市建設(shè)”和“城市雙修(城市修補(bǔ)和生態(tài)修復(fù))”等全國性的、運(yùn)動(dòng)式的行動(dòng)。從這個(gè)意義上來說,生態(tài)修復(fù)運(yùn)動(dòng)在中國的發(fā)生是積極的,也是必要的。我們需要關(guān)注的是,在這樣的運(yùn)動(dòng)中,景觀專業(yè)人員應(yīng)當(dāng)處于何種立場(chǎng)、發(fā)揮哪些作用。
中國的海綿城市建設(shè)和城市雙修運(yùn)動(dòng)均源于中央政府對(duì)于蔓延的城市病的警覺。當(dāng)全國一半以上的人口都居住在城市之中,城市生態(tài)和環(huán)境問題所引發(fā)的百姓的普遍不滿,將成為影響社會(huì)安定和國家安全的重大因素。因此,在住房和城鄉(xiāng)建設(shè)部的推動(dòng)下,一場(chǎng)全國性的城市雙修運(yùn)動(dòng)就此展開,海南省三亞市被設(shè)立為首個(gè)試點(diǎn)城市。本人作為這場(chǎng)運(yùn)動(dòng)的見證者和參與者,有必要對(duì)中國現(xiàn)階段的生態(tài)修復(fù)過程做出客觀記錄,以供后人在進(jìn)行相關(guān)研究時(shí)作為參考:
2012年11月8日,在中國共產(chǎn)黨第十八次全國代表大會(huì)上,首次提出“美麗中國建設(shè)”這一執(zhí)政理念,強(qiáng)調(diào)“把生態(tài)文明建設(shè)放在突出地位,融入經(jīng)濟(jì)建設(shè)、政治建設(shè)、文化建設(shè)、社會(huì)建設(shè)各方面和全過程”。
2013年7月20日,習(xí)近平總書記向生態(tài)文明貴陽國際論壇年會(huì)致賀,在名為《攜手共建生態(tài)良好的地球美好家園》的發(fā)言中指出:“走向生態(tài)文明新時(shí)代,建設(shè)美麗中國,是實(shí)現(xiàn)中華民族偉大復(fù)興的中國夢(mèng)的重要內(nèi)容?!敝链?,美麗中國建設(shè)與實(shí)現(xiàn)中國夢(mèng)的關(guān)系被清晰地描繪了出來。
2013年11月15日,習(xí)總書記在對(duì)《中共中央關(guān)于全面深化改革若干重大問題的決定》做出說明時(shí)指出:“山水林田湖是一個(gè)生命共同體,人的命脈在田,田的命脈在水,水的命脈在山,山的命脈在土,土的命脈在樹。用途管制和生態(tài)修復(fù)必須遵循自然規(guī)律……由一個(gè)部門負(fù)責(zé)領(lǐng)土范圍內(nèi)所有國土空間用途管制職責(zé),對(duì)山水林田湖進(jìn)行統(tǒng)一保護(hù)、統(tǒng)一修復(fù)是十分必要的。”至此,生態(tài)修復(fù)成為了美麗中國建設(shè)的必要工作。
2013年12月12日,習(xí)總書記在中央城鎮(zhèn)化工作會(huì)議上指出:“要依托現(xiàn)有山水脈絡(luò)等獨(dú)特風(fēng)光,讓城市融入大自然,讓居民望得見山、看得見水、記得住鄉(xiāng)愁?!薄俺鞘幸?guī)劃建設(shè)的每個(gè)細(xì)節(jié)都要考慮對(duì)自然的影響,更不要打破自然系統(tǒng)。為什么這么多城市缺水?一個(gè)重要原因是水泥地太多,把能夠涵養(yǎng)水源的林地、草地、湖泊、濕地給占用了,切斷了自然的水循環(huán),雨水來了,只能當(dāng)作污水排走,地下水越抽越少……解決城市缺水問題,必須順應(yīng)自然。比如,在提升城市排水系統(tǒng)時(shí)要優(yōu)先考慮把有限的雨水留下來,優(yōu)先考慮更多利用自然力量排水,建設(shè)自然積存、自然滲透、自然凈化的海綿城市。”在這里,海綿城市建設(shè)被作為城市生態(tài)修復(fù)的關(guān)鍵措施提出。
2014年2月,《住房和城鄉(xiāng)建設(shè)部城市建設(shè)司2014年工作要點(diǎn)》一文中明確提出:“改善城鎮(zhèn)人居生態(tài)環(huán)境,切實(shí)加強(qiáng)城市綜合管理,預(yù)防和治理‘城市病’,推進(jìn)城鎮(zhèn)化健康發(fā)展” “加快研究建設(shè)海綿型城市的政策措施”。隨后,共計(jì)16個(gè)城市入選第一批海綿城市建設(shè)試點(diǎn)城市。至此,作為中央意志的貫徹和執(zhí)行部門,住建部展開了實(shí)質(zhì)性的行動(dòng)。
2015年4月11~12日,住建部時(shí)任部長陳政高考察海南省,并在三亞提出了開展“生態(tài)修復(fù)、城市修補(bǔ)”的設(shè)想,將三亞作為試點(diǎn)城市。至此,生態(tài)修復(fù)被落實(shí)為改善人民生活和實(shí)現(xiàn)美麗中國夢(mèng)的全民運(yùn)動(dòng)。
2015年12月20~21日,中央城市工作會(huì)議召開。習(xí)總書記在會(huì)上發(fā)表重要講話,他強(qiáng)調(diào),“堅(jiān)持以人民為中心的發(fā)展思想,堅(jiān)持人民城市為人民……城市發(fā)展要把握好生產(chǎn)空間、生活空間、生態(tài)空間的內(nèi)在聯(lián)系,實(shí)現(xiàn)生產(chǎn)空間集約高效、生活空間宜居適度、生態(tài)空間山清水秀……要大力開展生態(tài)修復(fù),讓城市再現(xiàn)綠水青山?!弊〗ú吭谌齺喌鹊氐恼{(diào)研和預(yù)熱得到了中央的支持,為全國性的生態(tài)修復(fù)和海綿城市建設(shè)鋪平了道路。
2016年12月10日,全國生態(tài)修復(fù)城市修補(bǔ)工作現(xiàn)場(chǎng)會(huì)在三亞召開。歷經(jīng)一年半的三亞城市雙修試點(diǎn)工程驗(yàn)收,三亞紅樹林公園、東岸濕地公園等城市生態(tài)修復(fù)項(xiàng)目亮相。三亞市生態(tài)環(huán)境狀況得以改善,土地經(jīng)濟(jì)價(jià)值顯著提升(以東岸濕地公園為例,其帶動(dòng)周邊房地產(chǎn)價(jià)值在一年內(nèi)提升了150%)。會(huì)議之后,全國各城市的政府決策者參觀了三亞城市雙修項(xiàng)目的成果,并將學(xué)習(xí)經(jīng)驗(yàn)帶回各地。緊接著,一系列城市雙修項(xiàng)目陸續(xù)建立,一場(chǎng)全國性的城市雙修運(yùn)動(dòng)就此展開。
剖析三亞生態(tài)修復(fù)試點(diǎn)和全國的生態(tài)修復(fù)運(yùn)動(dòng),我們可以看到,在中國現(xiàn)有體制下,中央執(zhí)政為民、實(shí)現(xiàn)美麗中國夢(mèng)的國家意志,如何由一個(gè)城市的試點(diǎn)經(jīng)驗(yàn)轉(zhuǎn)化為千百個(gè)城市具體的民生改善運(yùn)動(dòng),并通過國家機(jī)器,將億萬人民動(dòng)員起來,使城市不良狀態(tài)迅速改變。而在這一過程中,景觀專業(yè)人員應(yīng)采用正確的理念和方法來引導(dǎo)和幫助決策者,確保這個(gè)善意的運(yùn)動(dòng)盡可能地走在正確的軌道上。
In China, national and top-down “movements” seem to be necessary to promptly address adverse and systematic events which are closely related to people’s life. Were they discussed without the context of China’s urban and rural communities, it is difficult to understand the history and development of these types of movements, such as the “Sponge City Construction” and “Urban Remediation and Ecological Restoration.” The movement of ecological restoration has been positive and necessary in China, and the role and contribution of landscape architect in these movements continue to evolve.
The movements of Sponge City Construction and Urban Remediation and Ecological Restoration are driven by the central government’s awareness of environmental problems in urban areas. As over 50% of the total population lives in urban spaces, criticism and dissatisfaction about urban ecological and environmental issues will begin to threaten social stability and national security. In response to this concern, the nationwide Urban Remediation and Ecological Restoration movement was launched with support from the Ministry of Housing and Urban-Rural Development (MOHURD). Sanya in Hainan Province was selected as the first pilot city that provides me, a participant in the movement, an opportunity to objectively record current ecological restoration processes in China.
On November 8, 2012, the 18th National Congress of the Communist Party of China approved the “Beautiful China Construction” program, which emphasized eco-civilization construction, alongside economic, political, cultural, and social development.
On July 20, 2013, General Secretary Xi Jinping made a speech at the Eco Forum Global Annual Conference in Guiyang in which he pointed out that to build the Beautiful China in the era of eco-civilization is significant to achieving the great rejuvenation of China. The key role of Beautiful China Construction to the realization of China’s rejuvenation was emphasized by the central government.
Later, on November 15, 2013, in the document of Explanatory Notes for the Decision of the CCCPC on Some Major Issues Concerning Comprehensively Deepening the Reform, General Secretary Xi expounded the importance of the mountains, rivers, forests, farmlands, and lakes to a life community. He argues that the spaces in which humans survive are interdependent; humans depend on farmlands, the farmlands on rivers, the rivers on mountains, the mountains on lands, and the lands on trees. He further pointed out that “l(fā)and use regulation and ecological restoration must respect the laws of Nature…. A new centralized governmental agency should be set up to lead, manage, and coordinate the affairs related to the usage of the entire territory of China, carrying out unified natural resources protection and restoration programs at a national scale.” Thereby, significance and necessity of ecological restoration in Beautiful China Construction was underlined again with a clear administrative vision.
On December 12, 2013, on the Central Urbanization Work Conference, General Secretary Xi pointed out the urgent need to integrate cities with their natural environment in support of existing landscapes, “l(fā)etting people see mountain, see water, and remember the nostalgia.” Moreover, he emphasized that in urban planning and construction, natural systems should be carefully conserved, rather than destroyed. “Breaking natural systems during urban construction, such as excessive concrete flooring, which causes decreases in woodlands, grasslands, lakes, and wetlands has become a core reason for urban water shortages. When natural water circulation is blocked, new rainwater contributes to urban flooding and is drained as sewage while unwisely pumping groundwater for daily supplies, causing huge resource waste and abuse….” To solve the problem of water shortage in cities, urban designers and landscape architects must comply with natural topography and vegetation. For example, to conserve stormwater, the Sponge City model helps store, infiltrate and purify rainwater. For this reason, Sponge City construction has become a key strategy in urban ecological restoration.
In February 2014, the Work Focus of Urban Construction Division of MOHURD again proposed to improve ecological urban inhabitation, to strengthen integrated urban management, to prevent and manage urban environmental problems, to promote healthy urbanization, and to accelerate research on policies and strategies for Sponge City Construction. Subsequently, sixteen Sponge City pilot locations were selected. It can be seen as a substantive action of the central government in implementing the movement.
In April 2015, Zhenggao Chen, the Minister of MOHURD, proposed advancing the idea of “Urban Remediation and Ecological Restoration” during a visit to Hainan Province. The city of Sanya was selected as a pilot location for exploring the idea. Ecological restoration has been regarded as an approach to improve people’s living standards and to realize the vision of Beautiful China with public engagement.
In December 2015, General Secretary Xi made a speech at the Central Urban Work Conference, which stressed sticking to people-oriented urban development as a way to balance efficient and intensive production, comfortable living, and beautiful ecological environments. “Making a sound living environment visible and functional in the city,” what he noted. The research and pilot project led by MOHURD in Sanya have received support from the central government, and the project is supposed to be a prime paradigm for nationwide ecological restoration and Sponge City Construction.
Finally, on December 10, 2016, the Conference of National Ecological Restoration and Urban Remediation was held in Sanya in celebration of the pilot program’s achievements. After the one-and-a-half-year pilot project in Sanya, several urban ecological restoration projects emerged, including the Sanya Mangrove Park and the East Coast Wetland Park. With these projects, the ecological and economic environment of Sanya has greatly improved. Construction of the East Coast Wetland Park has increased surrounding real estate price by 150%, for example. Municipal leaders who visited Sanya’s pilot projects brought ideas and strategies back to their home cities, and a series of Ecological Restoration and Urban Remediation projects have been launched throughout the country.
The Sanya pilot project is an example of the national ecological restoration movement, demonstrating the central government’s vision for improving people’s living quality and realizing the Beautiful China Dream. This dream can be achieved through the gradual development of pilot projects in hundreds of Chinese cities, and through state regulation and public engagement. Landscape architects have an important role to play in assisting municipal leaders and decision makers with appropriate ideas and approaches of ecological restoration to promote the national movement.
