Dilemma and Solution of Green Transportation Construction under the Background of Urban Development

With the development of the city and the increase of the population, the demand for transportation is increasing. The increases in transportation ways and demand have also brought certain energy and environmental problems to transportation construction. A good transportation environment and green travel experience have an important role in promoting the happiness of urban life and the sustainable development of society. Based on this, the following solutions are proposed for the construction and development of urban green transportation. First, as a guiding role, the government should formulate active transportation and green transportation policies to promote the reform of multiple public transportation methods. Second, as a leading role, the market can support a variety of the construction of green travel modes, which could encourage the development of shared bicycles and new energy vehicles. Third, as the main role of city, the citizens would like to choose green travel tools with the guidance in the conscious level. If we built green behavior into a fashionable business card of the city, green behavior will lead the city’s transportation construction and development.

Empirical Study on the Relationship between Economic Development and Urban Construction Land in China: Based on the Panel Data of Provinces

The panel data of 31 provinces,cities and autonomous regions was used in order to test the relationship between economic development and urban land. The result showed that the sequences of economic development and urban land were in accordance with first order integration. Secondly,there was cointegration between economic development and urban land and the cointegration equation illustrated that 10% of increase in GDP per capita would drive 4. 94% of expansion in city construction land. Thirdly,according to error correction model,economic development is the Granger cause of urban land expansion in the long term while the reverse relationship was not proved. In short-term,economic development and urban land expansion were Granger causes of each other. The long-term equilibrium can only regulate the short-term imbalance of urban land,arriving at 33. 83%. Therefore,the government should formulate related policies to encourage real estate developers and enterprises to increase land utilization efficiency,strictly control the increase of urban land and regulate short-term imbalance.

Urban rail transit loops are essential in urban rail transit systems and transportation networks.However,precise requirements and reference standards for rail transit loop design have yet to be established.There are certain areas for improvement in planning,construction,and operation.In the planning and design of urban rail transit loops,the scale of the city and the relationship between line operations should be considered to ensure that the line conforms to the city’s operating traffic conditions and can effectively cater to peak passenger flow requirements.This article presents strategies for planning,constructing,and operating urban rail transit loops,laying the foundation for the healthy operation of urban rail transit.

Urban Construction Land Suitability Evaluation Based on Improved Multi-criteria Evaluation Based on GIS(MCE-GIS): Case of New Hefei City,China

Urban construction land suitability evaluation(UCLSE)is a complex system engineering and the basis for rational use of the limited urban land resources in China.It has an important practical value on urban construction land use planning and management from the angle of methodology.As a widely used technique,traditional multi-criteria evaluation based on GIS(MCE-GIS),is not suitable for UCLSE.This study develops an improved MCE-GIS method which could be more suitable for UCLSE based on urban complex ecological system theory and the summary of the shortcomings of traditional MCE-GIS.The improvements include three aspects:a composite evaluation index system rather than natural indexes alone,an index weight calculated by using fuzzy Analytic Hierarchy Process(AHP)method rather than the common AHP method,and the integrated overlay rule,which includes selecting the minimum value,weighted linear combination(WLC)and simple summation.The main advantage of this improved technique is that it can make UCLSE more comprehensive,more operational and more reasonable.It can provide a scientific basis for decision making in the planning and management of urban construction land use.The improved MCE-GIS system has been adopted in the New Hefei City,Anhui Province,China.Based on the results of UCLSE in New Hefei,three functional areas including construction-appropriate areas,construction-restricted areas and construction-forbidden areas could be worked out,in which 36.90%of the total study area could be developed as urban construction land and the remaining 63.10%should be protected as reserves land or as ecological land.Furthermore,the results can provide scientific decision support for spatial planning and eco-environment protection in New Hefei.

The Evolution of Urban and Rural Construction Land Based on Spatial Econometrics:A Case Study of Bijie City

How does the construction of China’s ecological civilization affect the health burden of urban and rural residents?

Accelerating the construction of ecological civilization and promoting the management of health environment problems is one of the core elements of the implementation of the“Beautiful China”and“Healthy China”strategies with Chinese characteristics in the new era.Based on the scientific connotation of ecological civilization,this paper systematically assesses the level of interprovincial ecological civilization construction in China using the combined CRITIC empowerment method and explores the impact of ecological civilization construction on the health burden of urban and rural residents using interprovincial panel data from 2003 to 2018 with the help of panel feasible generalized least squares,simultaneous equation estimation,and the extended regression model.It is found that there is a significant inverted U-shaped relationship between provincial ecological civilization construction and urban and rural residents’economic health burden,as well as a significant U-shaped relationship between ecological civilization construction and urban and rural residents’disease burden.Fiscal decentralization,urbanization,and industrialization are the three important indirect mechanisms through which ecological civilization affects the health burden of urban and rural residents,and fiscal decentralization plays a typical role in crowding out the health effect of ecological civilization.In the eastern and central regions,ecological civilization construction has effectively reduced the health burden of urban and rural residents,but it is more significant for improving the economic health burden of rural residents.While the“catching-up trend”of the progress of ecological civilization construction in the western region is obvious,ecological civilization plays an important role in alleviating the economic health burden of urban residents.After the robustness test,the conclusion still holds.This study provides an important empirical basis for local governments to improve the accuracy of their policies in promoting the“Beautiful China”and“Healthy China”strategies.

Analyzing and Pondering on the Regulation of Urban Construction Land Expansion

Along with the economic development and the acceleration of urbanization,urban construction land expands rapidly in China,and has resulted in a series of socio-economic problems.This article summarized the major points of controlling the unchecked and rash expansion of construction land in the academic circle,and analyzed the problems of regulating the expansion of construction land from three aspects.First,this article analyzed the relationships between socio-economic development and urbanization from the historical viewpoints,and pointed out that the expansion of construction land is a historical phenomenon which will be surely appeared in the development of human race.Second,the authors utilized two-sector model to analyze the importance of urbanization in the socio-economic development from the academic angles.At last,the authors utilize four-quadrant model and bidrent curve model to analyze the influence that brought by the strict control of construction land expansion.Through analysis,this article drew some conclusions.First,the expansion of construction land is a phenomenon which will surely appear in the social development.It is impossible to accomplish the national modernization on the basis of dualistic structure between urban and rural areas.Second,under the function of rent gradient gap,strict control of construction land expansion will not only obtain the anticipated effects,but also cause a series of socio-economic problems,such as land-levying contradiction,the appearance of limited property right house,and being dependant on lease instead of expropriation.Third,unreasonable policies and governmental behaviors are the roots of the unchecked and rash expansion of urban construction land.Based on these conclusions,this article proposed that three transformations should be realized to regulate the unchecked and rash expansion of construction land:transfers from quantity regulation to quality regulation,from direct regulation to indirect regulation,and from single-measure regulation to multi-measures regulation.

Study on Jinan urban construction planning based on the protection of karst landscape

Study on urban construction planning based on karst landscape protection contributes to sustainable development of urban construction in karst area. Jinan is a city famous for karst spring water. Karst landscape plays a decisive role in urban construction. Through hydrogeological analysis, the distribution characteristics of karst mountain, cave, gully and flat dam in Jinan are analyzed. It is revealed that various karst landforms are involved in the spring circulation process to varying degrees. Some karst landforms have been destroyed in the process of urban construction and the karst landscape has been overexploited resulting in the direct or indirect weakening of spring water recharge and infiltration capacity and the decrease of spring water flow. Through the study of the principle of organic combination of karst landscape and urban construction planning, on the basis of protecting the ecological environment of the south, paying attention to the overall protection of the karst geomorphology system and the principle of accessibility of the karst landscape, the development countermeasures guided by urban planning are put forward based on karst landforms protection. On the basis of fully considering the special karst landform conditions in Jinan, the countermeasures are that the ecological control red line of urban construction planning should be set up based on karst mountains and valleys in southern of Jinan City. It is suggested that the bare carbonate rock continuous mountain foot line in the direct recharge area should be taken as the south control red line of urban development and included in the overall planning. The urban landscape is mainly displayed in the main axis based on karst mountains and springs, constructing East-West Axis-characteristic Landscape Belt along the Wufeng Mountain-Langmao Mountain-Hero Mountain-Qianfo Mountain-Long cave-Panlong cave-Jinping Mountain line and North-South Axis Landscape Belt along the Baotu SpringQianfo Mountain line, Baiquan-Panlong cave line, Baimai spring-Dajian Mountain line. Based on the karst river valleys and the river system, the urban spatial pattern is constructed, forming ecological corridor, restoring infiltration function of river. The form of urban construction should be shaped based on karst landform and the river system. The main form is semi-star like radiation type and the combination of central intensive type and zonal type. Based on the whole protection of karst geomorphology system and the scientific molding of karst landscape, the ecological landscape city with the symbiosis of spring and urban can be built.

Therefore, organic combination of eco-civilization construction and urbanization will be the key solving the problem. As one of preconditions of planning and project, environmental impact assessment will also play pivotal role in eco-civilization construction of urbani- zation in China. We detailedly introduce environmental impact assessment, and put forward how to effectively use environmental impact assessment for the eco-civilization construction of urbanization in China.

Input-output Efficiency of Elements of Urban Construction Land in Beijing: Empirical Analysis Based on Panel Data of Jurisdiction

Based on the Data Envelopment Analysis method,and by using CCR and BCC model,Super Efficiency model and Malmquist model guided by input efficiency,the input-output efficiency of elements of urban construction land in different jurisdictions of Beijing from 2005 to 2015 was studied.The results showed that there were obvious differences between input-output efficiency of elements of urban construction land in different jurisdictions of Beijing,among which the efficiency of the core area of capital,Yanqing District,Fangshan District and Huairou District was relatively high,while the efficiency of Daxing District,Fengtai District and Miyun District was relatively low.There was no obvious correlation between efficiency differentiation and location factors,which is mainly caused by whether the land use in each jurisdiction has scale effect,whether the technology is improved,whether the input is redundant and whether the output is insufficient.For the jurisdiction of inefficient land use,we should strengthen the consciousness of intensive land use,improve the technical level,appropriately reduce the redundancy of input elements,and pay attention to the output of social and ecological benefits.

Properties of Rapid Hardening Controlled Low Strength Material Made of Recycled Fine Aggregate from Urban Red Brick Construction Waste

In some cases of emergency backfill engineering projects, traditional backfill materials cannot meet the requirements of fast construction due to their long curing time. This study presents a new kind of rapid hardening controlled low strength material, which utilizes both rapid hardening sulphoaluminate cement and recycled fine aggregate from urban red brick construction waste. Totally, sixteen mixtures were prepared for the experiment with different cement-to-sand ratios and water-to-solid ratios. The flowability and bleeding rate of fresh mixture were measured to evaluate its workability, and the compressive strength of hardened mixture was tested to evaluate its rapid hardening and mechanical properties. Test results indicate that rapid hardening controlled low strength material containing recycled fine aggregate from urban red brick construction waste can achieve the desirable flowability, but the bleeding rate increases with the increase of flowability. In addition, 2-hour compressive strength can reach 0.08 - 0.12 MPa, and 4-hour compressive strength is 0.32 - 1.54 MPa, which can meet the requirements of emergency backfill construction. At last, based on the derived compressive strength, a fitting model for predicting compressive strength evolution of this new rapid hardening backfill material is developed, which fits accurately with these experimental data.
