The modernization of territory spatial governance plays an essential role in realizing Chinese modernization. Towards the goal of high-quality development, promoting subject systems and professional learning provides fundamental and strategic support for the modernization of territory spatial governance. This paper focuses on the construction of the subject system of territory spatial governance from three aspects of the subject framework, the professional learning mode, and the team establishment strategy. We propose a life-cycle strategy for establishing the subject system of territory spatial governance in terms of the unified survey, spatial planning, utilization controlling, approval supervision, and construction of laws and regulations. We build a systematic talent training mode with the goal of generous theoretical foundation, method synthesis and excellent practical ability, and design a multi-field team construction strategy for territory spatial governance. In order to guarantee the modernization of land and space governance, the future works should focus on the synergetic development of subject development, talent training and team building.

The optimal allocation of land‐use is an important technical means to solve the contradiction be‐ tween supply and demand of land resources and to coordinate social and economic development with eco‐ logical protection, and it is also one of the key issues that need to be solved for the sustainable use of land resources. With the development of spatial simulation and intelligent optimization technology, the theoretical basis and methodological system of land‐use optimization are constantly updated. Based on bibliometrics analysis, this paper systematically summarized the driving theories and methodology of land‐use optimal al‐ location at home and abroad, focused on the application of spatial simulation models and intelligent optimization models in land‐use optimization problems, discussed and prospected the challenges and the future development of optimal land‐use allocation, and put forward that: The coupling drive of natural and human processes, spatial collaboration of multiple models, embedding big data knowledge mining methods, and the support of digital twin technology, should be the research direction of the next stage in the field of optimal land‐use allocation.

Rural accessibility can depend mainly on the services and facilities available, as well as the travel options for each group in the settlements. The layout of rural living facilities can be optimized to enhance the rural development and the happiness index of rural residents. The rural accessibility of facilities has gradually received much attention in recent years, since the rural revitalization strategy was launched in China. But, the current evaluation can be limited to a single evaluation object and perspective. Taking the Gao’an City, Yichun City, Jiangxi Province, China, as the study area, the spatial distribution characteristics of rural accessibility were analyzed from the perspectives of “Threshold- Supply and Demand”. An accessibility zoning model was then proposed to determine the driving mechanism and optimization path of rural accessibility using a coupling perspective. Firstly, the accessibility evaluation index system of rural life was constructed by considering four types of facilities: education, medical, commercial and cultural, and sports, together with the needs of rural residents in daily life and the demand for higher facilities and services, as the living standard improved. Secondly, a network data set with the time cost was constructed using the ArcMap network analysis tool in the road network of Gao’an City. The “isochronous analysis method for service demand” was used to obtain the lowest time cost of reaching specific living facilities at any location. The “two-step floating catchment area method” was improved to calculate the accessibility from the supply perspective. In addition, an accessibility zoning model was proposed to identify the four accessibility types using the coupled perspective of “Threshold-Supply and Demand”. There were different spatial distribution characteristics of facilities and settlements in the rural areas from those in cities. Finally, the accessibility model was evaluated on the influencing factors of rural accessibility for the optimal paths and specific measures. The results show that there were some large barriers to rural preschool education, medical treatment for major diseases, logistics, express delivery, and cultural and sports activities from the perspective of the minimum time cost, indicating the significant imbalance between urban and rural development. A relatively balanced regional supply and demand were observed in the education resources and population. The medical facilities presented a higher supply in some township centers than that in urban areas, whereas, there was an outstanding urban bias in the supply of commerce, culture, and sports. Four types (namely high threshold-low supply, high threshold-high supply, low threshold-low supply, low threshold-high supply) of accessible and inaccessible zones were divided in the Gao’an City under the rural accessibility zoning using the coupling perspective. Among them, the rural living accessibility was also influenced by the spatial impedance and supply-demand relationship. Three aspects can also be optimized: the spatial relationship adjustment, living facilities and road construction, and flow of living service elements. Therefore, decision-making can be very necessary to balance rural accessibility from different perspectives. A trade-off strategy between the different zoning and facilities can greatly contribute to optimal rural living and the layout of rural settlements. [ABSTRACT FROM AUTHOR]
