Study on Ecological Restoration Model of the Fluctuating Belt of Reservoir at the Xueye Lake in Laiwu City,Shandong Province

Fluctuating belt of reservoir is a dry-wet alternating area with special ecological conditions, quality of its ecological environment directly infl uences the reservoir ecosystem. This paper, on the basis of analyzing ecological functions and problems of the reservoir fl uctuating belt, elaborated the ecological restoration of the fl uctuating belt of the Xueye Lake in Shandong Province. According to the coastal planning types and water resource conservation needs, 4 ecological restoration models were given, i.e., pond wetland model, terraced fi eld model, conservation model, and consolidated embankment model(or Baokan model), and also 7 vegetation restoration models. Landscape planning and design of the reservoir fl uctuating belt was reviewed from the perspective of ecological restoration, to establish the eco-friendly fl uctuating belt, and this study has high promotional value.     

地震对城镇地表水厂原水浊度的影响及应对措施

地震引起的地质松动、滑坡、崩塌、植被破坏等很难在短时间内恢复原状或者稳定下来,并且上游水库为保证坝体安全而被迫大量放水,强烈的河道冲刷及山体滑坡会造成地表水体泥沙悬浮物质等大量增加,导致地表水厂原水浊度剧烈变化,严重影响水厂安全运行。以"5.12"地震时绵阳市第三水厂原水浊度变化为例,说明地震对地表水厂原水浊度的影响程度及影响时间,并针对震后地表水厂原水浊度可能出现剧烈变化(数值从几十至两三万NTU)的情况,提出地震灾区地表水厂应针对高浊度原水在原有常规工艺的基础上增设预沉池(自然预沉池或混凝预沉池)工艺,实践证明运行效果良好,为保障地震灾区其他城镇供水安全提供参考和技术支持。     

How does the community resilience of urban village response to the government-led redevelopment? A case study of Tangjialing village in Beijing

Building on the critical resilience literature, this study aims at analyzing how the community resilience (CR) of urban village (UV), which is challenged by multiple natural and socio-economic disturbances such as climate change, land occupation, and industrialization, responses to the government-led redevelopment (GLR) and its hidden mechanism. A conceptual framework incorporating social, economic, institutional/governmental, material domains and community capital was established with reference to the work of Cutter, Burton, and Emrich (2010), and was applied as the conceptual springboard to assess the resilience of Tangjialing village. The results suggested that the GLR in Tangjialing village was generally a successful practice for enhancing CR, which was tightly associated with the economic empowerment for local residents and formalization of informal economic activities and negatively affected by insufficient public engagement. Accordingly, policy implications about enhancing the resilience such as protecting the farmers' “private rights” as landowners, providing employment guidance and assistance and implementing cooperative planning were proposed.     

Spatial pattern of population mobility among cities in China: Case study of the National Day plus Mid-Autumn Festival based on Tencent migration data

Population migration, social check-in, vehicle navigation, and other spatial behavior big data have become vital carriers characterizing users' spatial behavior. “Tencent Migration” big data can real-timely, dynamically, completely and systematically record population flow routs using LBS device. Through gathering residents daily mobility among 299 cities in China during the period of “National Day–Mid-Autumn Festival” (NDMAF) vacation (from September 30 to October 8) in 2017 in “Tencent Migration” and defining three periods with “travel period, journey period, return period”, this paper is designed to analyze and explore the characteristics and spatial patterns of daily flow mobility cities from the perspective of population daily mobility distribution levels, flow distribution layers network aggregation, spatial patterns and characteristics of the complex structure of the flow network. Results show that “Tencent migration” big data clearly discovers the temporal-spatial pattern of population mobility in China during the period of NDMAF. The net inflow of population showed a diamond shaped with cross frame support in each period, the four nodes of the diamond contain Beijing, Shanghai, Guangzhou and Xi'an. Main mobility assembling centers are distributed in the urban agglomerations of Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and Chengdu-Chongqing, and those centers have strong coherence with those urban hierarchies. Most cities are in a state of “relative equilibrium” in the population flow, and clear hierarchical structure and level distinction can be identified. Spatial patterns of population mobility present obvious core-periphery structures. The Dali-Hegang line exhibits a significant network of spatial differences in terms of boundary divisions. In this context, the spatial distribution of urban network could be summarized as “dense in the East and sparse in the West”, and the core linkages of urban network could be characterized as “parallel in the East and series in the West”. The whole network exhibits a typical “small world” network characteristic, which shows that China's urban population flow network has high connectivity and accessibility during the period of NDMAF. The network has a distinct “community” structure in the local area, including 2 national communities, 2 regional communities and 3 local-level communities.

胶东半岛山岳道家文化景观的序列性“风景道”研究

胶东半岛凭借三面环海的地理区位,成为道家思想的重要发源地。金元时期,内丹派全真道于此创立,使该地山岳道家文化景观得以迅速发展。在半岛特殊的自然气象、资源、地貌条件影响下,山岳道家文化景观的营造呈现出"序列性"特征,且其物象与内丹修道理论密切相关,形成诸多"山地风景道"。通过田野调查、测绘、访谈,探讨该类"风景道"的环境基底特征和文化内涵,总结"风景道"的景观层次与要素组成,并对其空间特征与要素布局进行分析。研究发掘了胶东半岛山岳道家文化景观的潜在规律,为保护当地该类景观提供新的视角,亦可为其他地域该类景观保护提供借鉴。     

Confucian ecological vision and the Chinese eco-city

“Living in harmony with nature” is the slogan of the Chinese government’s campaign against the environmental crisis and has become the target of many mega eco-city projects which have emerged in China during the last decade. A number of papers in Chinese journals attribute this slogan to the government’s revival of the Confucian ecological vision, combined with western technology. This paper first compares the concept of nature in these mega eco-cities and the Confucian concept of tianrenheyi, the unity of Heaven and Humanity, suggesting that the human–nature relationship in eco-cities is essentially a consumer–commodity relationship, which is void of the sacredness or moral association of the human–nature relationship in the unity of Heaven and Humanity. Secondly, drawing on the theory of ecology and interconnected systems and noting that the failure of eco-city projects lies in the separation of the eco-city from the city itself, I suggest that the eco-city’s approach of taking nature as a guinea pig of technology in a “vacuum space” is quite opposite to the Confucian idea of the unity of Heaven and Humanity which emphasizes the interconnectedness of all inorganic and organic forms. In conclusion, I evoke Wang Shu’s practice of sustainable architecture to illustrate a more authentic, up-to-date interpretation of the Confucian ecological vision—investigating the relational reality, developing one’s moral nature and cultural intuition.     

Evaluating the institutional performance of the Pearl River Delta integration policy through intercity cooperation network analysis

Adopting a macroscopic perspective, this study employs intercity cooperation network analysis to assess the institutional performance of the Pearl River Delta's (PRD) integration policy. To assess whether the existing PRD intercity cooperation network is advancing the three objectives of the PRD integration policy in terms of cooperation patterns, actors' involvement, and cooperation fields, this study analyzed news published on the Internet and official government websites. The study concludes that: (1) the Shenzhen-Dongguan-Huizhou sub-region (SDH) and the Zhuhai-Zhongshan-Jiangmen sub-region (ZZJ) are entirely integrated as institutional entities, while Zhaoqing and Yunfu have not been integrated into the Guangzhou-Foshan-Zhaoqing sub-region (GFZ); (2) the PRD integration process remains a government-led administrative process, with market and civil society actors having had little influence on the governance structure; and (3) the primary areas of cooperation involve institutional design and economic development, and secondary functions, such as entertainment, education, and environmental protection, have not been fully undertaken. We also consider that the PRD's institutional spatial structure is a monocentric structure centered on Shenzhen, which is inconsistent with previous studies indicating a functional spatial structure known as a “Polynuclear Urban Region.”     

Planning history research in China: past,present, and future

Chinese planning history research has gradually developed out of architectural and construction history. Its main foci have been the periodization of planning practice and the long-term evolution in the form of modern cities. So far, there has been little work on the main body of practice, planning procedure, implementation, and effectiveness. The authors argue that it is time to shift the approach of planning history and explore how it can best contribute at a practical level to the theory and practice of planning in China.
