A new approach towards the sustainability of urban-rural integration:The development strategy for central villages in the Abbasiya District of Iraq using GIS techniques

The development of rural areas usually has a positive impact on the urban-rural integration. This study explores an innovative approach to stimulate rural development by proposing qualified villages as central villages that can provide basic urban services for their residents and residents of neighboring villages. This approach can contribute to overcoming the various problems that rural areas faced at the social, economic, and environmental levels. It seeks to achieve spatial sustainability of rural areas, representing a new approach by integrating urban development methods to revitalize rural villages. The study analyzed 15 villages belonging to Abbasiya District of AL Kufa City in the Najaf Governorate of Iraq. Based on the GIS techniques and the analysis of urban service indicators(village population, percentage of urban building materials used in villages, distance between village and health centers, distance between village and main roads, nature of economic activity, distance between village and educational institutions, distance between village and drinking water sources, number of communication towers, and distance between village and urban administrative center), this study proposed that Abu Gharb and Albu Ghraib can served as central villages in Abbasiya District in the future. This study establishes a new rural spatial structure to achieve rural sustainable development, improves the development status of rural areas, and provides a theoretical basis for the government and relevant institutions to use urban service indicators, achieving rural sustainable development and formulating relevant development policies in Abbasiya District.

Impact of Urban Public Service Facilities on Distribution Pattern of Housing Price

The impact of different public service facilities is obtained by investigating the infl uence of public service facilities on distribution pattern of housing price in 25 cities.According to the survey results,public education service facilities have the highest weight and the greatest impact,which also refl ects the root of“school district housing fever”from the side.Public sports service facilities have the lowest score when compared with other options.This is not because public sports service facilities are not important,but is determined by actual situation of social development and actual living standard of residents in China.From the improvement and enhancement of urban public service facilities,the construction of public service facilities should be convenient for people’s education,health,culture and entertainment.

Review of urban ecosystem services from 2010 to 2020:An analysis based on CiteSpace

This paper systematically combs 416 literature on urban ecosystem services (UES) in China and other countries from 2010 to 2020,and carefully interprets the abstracts of 383 effective literature.According to the classification method of the research perspectives of ecosystem services proposed by Luederitz C,the literature is divided into six categories:ecology,governance,methods / tools / guidelines,social networking,economy and planning,and Excel and CiteSpace software were used for data statistical analysis and visual processing.The research shows that:in terms of research perspectives,foreign researches are evenly distributed in six categories:ecology,governance,methods / tools / guidelines,social networking,economy and planning,while domestic research perspectives are relatively concentrated in three categories:economy,governance,methods / tools / guidelines,and the proportion of economic category is particularly significant.In terms of research contents,there are more studies on climate governance,decision-making mechanism and method innovation abroad,while there are more studies on the measurement of carbon sequestration and oxygen releasing,the evaluation of ecological security pattern and the quantitative evaluation of UES’s economic value in China,and there are less studies on institutional organization structure and policy tools,innovative methods of UES’s value evaluation,the potential role of UES on some social phenomena,the relationship between UES and residents’ behavior and perception.

Research on urban intelligent fashion advertising service model based on wearable devices

Why rapid urbanization can’t improve employment absorption capacity of service industry in China:reflections on innovating the model of interaction between service industry development and urbanization under economic transformation and upgrading

Mathematical models show that the urbanization process is an important factor affecting the transfer of labor among economic sectors.The regression results using time-series data since China’s reform and opening up show that there is significant positive correlation between urbanization and the service industry’s ability to create jobs.However,there is no Granger Causation between them.Therefore,China should shift from focusing on industry park construction to paying more attention to improving urban functions by increasing their employment density of urban services.

Study on Braking Energy Regeneration System for City Bus

Braking of the urban vehicles of public service wastes a large number of engine energy in the condition of starting and stopping frequently. Aiming at the problem, an electro-mechanical braking energy regeneration system was proposed which adopted a high-speed flywheel and a battery to recover the braking energy and achieve the secondary traction for the auxiliary start function. The system strategy was designed and the braking simulation was processed to validate its feasibility. The experiment results show that the system can effectively recover the braking energy, improve the starting performance of the city bus and it can be applied to the engineering.

Spatially explicit urban green indicators for characterizing vegetation cover and public green space proximity: a case study on Brussels, Belgium

Cities often have a substantial green infrastructure,which provides local ecosystem services that improve the quality of life of urban residents.These services should be explicitly addressed in urban development policies,and areas with insufficient vegetation and limited access to public green spaces should be identified.This paper presents two spatially explicit urban green indicators that are derived using remote sensing imagery,freely available map data and spatial analysis tools from open source geospatial libraries and commercial software.The first indicator represents proportional green cover(public as well as private)in the vicinity of each building within a city.The second indicator quantifies the proximity of public green spaces as walking distances from buildings to actual park entrances.A dasymetric mapping approach was used to take spatial variations in population density into account.This allows representing the indicators from the perspective of citizens instead of buildings,which may be more meaningful for deriving statistics at city level or at the level of neighbourhoods or administrative zones.The potential use of these indicators in a planning context is discussed on a case study carried out for the city of Brussels,Belgium.

Research strategy for constructing a green infrastructure network based on spatial prioritization

The destruction of the ecological system caused by urban expansion has led to the environmental deterioration,cities have become increasingly vulnerable.In this study,six districts and counties along the Yellow River in Zhengzhou were selected as the study area.First,green infrastructure elements were extracted by morphological spatial pattern analysis.Then,outside the urban areas,we used connectivity analysis to evaluate the importance of core areas,adopted minimum cumulative resistance model to extract potential corridors,and identified the important corridors by using the gravity model.Finally,in the urban areas,we set up an evaluation system to assess the demands for ecosystem services.The results showed that:(1)Seven landscape types of green infrastructure be identified in study area.(2)There are 17 vital cores,136 potential corridors,and 24 vital corridors outside the urban areas.(3)The blocks with high demand for ecosystem services are mostly concentrated in the old blocks with dense populations and poor infrastructure,and there are 5 blocks with comprehensive high-demand.Based on identified importance for green infrastructure land space,and high-demand level for ecosystem services areas in this study,a green infrastructure net plan was proposed based on spatial conservation prioritisation.

Enriching Farmers through Sharing: Improving People’s Livelihood and Well-Being in the Modernization of Agriculture and Rural Areas in China

Shared development is an important means by which to improve people’s livelihood and well-being in the new era. During the 13th Five-Year Plan period (2016–2020), China has made great achievements in the three major aspects of targeted poverty alleviation through industrial development, development of special rural areas, and equalization of urban and rural infrastructure and basic public services. In addition, the important experience of multi-agent participation, multi-mode guidance, and multi-line promotion has been accumulated in the individual, regional and urbanrural dimensions. However, there remain some deficiencies, such as low policy efficiency, poor matching ability, and prominent structural problems. At the beginning of the 14th Five-Year Plan (2021–2025), the task of enriching farmers through sharing has been faced with many challenges, such as major changes in the focus of poverty governance, greater numbers of restraints on the development of special rural areas, and heavy responsibilities of equalizing urban and rural infrastructure and basic public services. Therefore, it is necessary to acquire a profound understanding of the new development concept, and to continuously enrich farmers through sharing in terms of accelerating the improvement of the institutionalized poverty reduction system in the new era, actively building a green development system of agriculture and animal husbandry in special rural areas, and striving to create a fair and complementary urban and rural infrastructure and basic public service system.
