Spaces for employment and residence form the skeleton of urban layout.Although their carbon confinement is evident in the academic circle,little attention is paid to the employment-residence separated and long-distance motorized commuting clusters,and the difference in low carbon pathways is not fully taken into account.Based on qualitative and quantitative analyses,three types of employment and residence space are illustrated,and the different elements of carbon confinement are recognized to establish a low carbon optimization strategy:first,residence dominated clusters shall adjust land use structure towards a compact and mixed use pattern;second,employment-residence balanced clusters shall focus on central places for a multi-centered wide range structure;third,employment dominated clusters shall stress employment-residence connection and establish a green transit system.
2023年6月2日,由兰州理工大学、西部"9+1+1+2"建筑类专业教学联盟(以下简称"专业教学联盟")主办的2023联合毕业设计终期汇报暨设计竞赛在兰州理工大学取得圆满成功.西部九校建筑类专业教学联盟是由长安大学发起,西北大学、昆明理工大学、四川大学、西北工业大学、新疆大学、西南交通大学、云南大学、西华大学、兰州理工大学等西部10余所建筑类院校组成的教学联盟,每年举办3个专业(建筑学专业、城乡规划专业、风景园林专业)的联合毕业设计及设计竞赛,以期为参赛院校及师生创建一个包容开放、共生共享、协同融合的交流平台,加强跨专业互动与交流.
The systematic farmland protection is significant to national food and ecological security.With an analysis of the quantity,quality,and ecological needs of farmland protection,an analytical framework of systematic protection with rigidity,elasticity,and resilience is established based on the essence of farmland protection.The study shows that in farmland protection,bottom line constraint and use control are the foundation,elastic land consolidation and layout improvement are the tool,and resilient functional balance and system stability are the essence.The rigid-elastic combined use control,internal and external forces supported resilience improvement,and eco-produce value realization incentive are the major content and orientation of"rigid,elastic,resilient"systematic farmland protection.
Conventional strategies for arable land protection,primarily centered on"controlling non-agricultural development"encountering the challenges of diverse demands of food security under the big food approach and the objectives of sustainable arable land utilization within the ambit of the comprehensive food strategy.Through a comprehensive examination and synthesis of the interconnections between the big food approach and food security,arable land protection,and the expansion of national land resources,the inherent rationale that connects the big food approach with the governance of"non-grain production"on cultivated land is elucidated.Further spatial governance strategies and safeguards for the"non-grain production"of cultivated land are proposed,aiming to provide insights and references for arable land resource protection and spatial optimization allocation in the future.
As the demonstrative zone of innovative development and pioneer zone of high quality development,the national high-tech zone helps bolster the cultivation of innovative activities and development of innovative economy.Introducing innovation ecosystem theory and concepts of innovation group and innovation population,the national high-tech zone innovative space system,dominated by innovative space cluster and innovative space unit,is established.The organizational logic of innovative space cluster is concentration for heterogeneous subjects in technology application,knowledge production,and service expansion,and the organization logic of innovative space unit is composite and diversified spaces for the behavioral needs of innovative groups and enterprises.
