Study on the Current Situation of Urban Integration of Aboveground Space and Underground Space:Under the Background of China’s Land Spatial Planning

Urban underground public space has a synergistic effect with its surrounding urban aboveground functions or facilities,which reflects the complementarity between underground functions and urban functions.The research analyses the degree of integration through the case study of urban aboveground space and underground space in China.The research method of this paper will give different evaluation criteria to public transport and public space and the influencing factors of space integration.The indicators of public transport include the number of subway lines and underground parking spaces.The evaluation standard of public space is the area of underground space and the number of floors of underground space.The subway entrance and exits are selected as the evaluation index for the aboveground and underground transition space.Through the specific analysis of 7 selected cases,it provides arguments for the research.The average rent in the case is taken as the dependent variable.Through the regression model,the influencing factors of the integration of aboveground and underground space are determined.The purpose of the study is to explore the influencing factors of the integration of aboveground space and underground space,and how to optimize the integration of aboveground and underground space.

China’s spatial(dis)integration as a multiethnic paradox:what do the interprovincial data say?

Using China’s interprovincial panel data,this paper shows that the negative effect of distance-related transactions costs on interprovincial trade tends to rise from 2000 to 2010.After constructing China’s 56 ethnic groups into a single,interprovincial similarity index,I cannot find any evidence that supports the view that ethnic links should serve as a factor promoting bilateral trade.However,my estimated coefficients on 37 major ethnic groups show that both positive and negative ethnic influences on trade exist in China.Specifically,14 ethnic groups(Lahu,Qiang,Jingpo,Tu,Mongol,Manchu,Hui,Zhuang,Dongxiang,Daur,Kirgiz,She,Maonan,and Tibetan)are found to contribute to China’s interprovincial trade,while five ethnic groups(Han,Va,Kazak,Dai,and Blang)tend to impede China’s interprovincial trade.Since all these estimated results are statistically significant,the ethnic influences on China’s spatial(dis)integration remain only but as a paradox.

Strategic Planning for Avoidance of Catastrophic Flood Consequences

The present study is to deal with the strategic planning in avoidance of all catastrophic consequences of major flood in West Attica region in 2017 and is divided into three main sections.The first one comprises the study of the internal and external environment of the Regional Unit of West Attica with analysis of resources,procedures,culture that governs the internal environment,external bodies and mapping through PESTEL(Political,Economic,Socio-Cultural and Technological)analysis as components of the external environment.The second section comprises the vision and mission of this strategic plan and specializes in reporting and analyzing the strategic objectives as well as the actions that characterize them in order to complete the mission that has been set and to achieve the vision that has been planned.The last section focuses on the feasibility of the above proposals formulated in the midst of actions and strategic objectives with the help of SWOT(Strength,Weakness,Opportunity,and Threat)analysis and concludes with a proposal for the implementation of strategic planning with the implementation of the Integrated Spatial Investment tool.

Conceptual design and implementation of spatial data warehouses integrating regular grids of points

Spatial online analytical processing(OLAP)and spatial data warehouse(SDW)systems are geo-business intelligence technologies that enable the analysis of huge volumes of geographic data.In the last decade,the conceptual design and implementation of SDWs that integrate spatial data,which are represented using the vector model,have been extensively investigated.However,the integration of field data(a continuous representation of spatial data)in SDWs is a recent unresolved research issue.Enhancing SDWs with field data improves the spatio-multidimensional analysis capabilities with continuity and multiresolutions.Motivated by the need for a conceptual design tool and relational online analytical processing(ROLAP)implementation,we propose a UML profile for SDWs that integrates a regular grid of points and supports continuity and multiresolutions.We also propose an efficient implementation of a ROLAP architecture.

Supporting integrative maritime spatial planning by operationalising SEANERGY – a tool to study cross-sectoral synergies and conflicts

With growing pressures on marine ecosystems and on marine space,an increasingly needed strategy to optimise the use of marine space is to co-locate synergic marine human uses in close spatial–temporal proximity while separating conflicting marine human uses.The ArcMap toolbox SEANERGY is a new,cross-sectoral spatial decision support tool(DST)that enables maritime spatial planners to consider synergies and conflicts between marine uses to support assessments of co-location options.Cross-sectoral approaches are important to reach more integrative maritime spatial planning(MSP)processes.As this article demonstrates through a Baltic Sea analysis,SEANERGY presents a crosssectoral use catalogue for MSP through enabling the tool users to answer important specific questions to spatially and/or numerically weight potential synergies/conflicts between marine uses.The article discusses to what degree such a cross-sectoral perspective can support integrative MSP processes.While MSP integrative challenges still exist,SEANERGY enables MSP processes to move towards developing shared goals and initiate discussions built on best available knowledge regarding potential use-use synergies and use-use conflicts for whole sea basins at once.
