The optimization of the territorial spatial pattern is a vital task. The territorial spatial planning and control plays an important supporting role in realizing the "dual carbon" goal. Based on the optimization of the territorial spatial development and protection pattern, this paper discusses the theoretical transformation, the key ways and corresponding "carbon neutralization" management strategies of the territorial spatial planning and control under the "dual carbon" goal, to help the implementation of the "dual carbon" goals. It is shown that the key points of the territorial spatial pattern optimization and the planning response to adapt to the "dual carbon" goal in the future include:constructing the "dual carbon" responsibility regional division system based on the main functional area, exploring the theoretical system for the carbon emission reduction and the carbon sink increase from "air" to "land", and studying the key planning technical ways to help the fine management of the "carbon neutralization".

In the context of the goal of the carbon peak and the carbon neutrality, this paper analyzes the challenges of the territorial spatial planning in the carbon technology system integration, the quantitative evaluation of the carbon benefits, the effective implementation of the carbon targets, and proposes the requirements of the adaptation transformation in five aspects:the planning target, the planning scale, the planning vision, the planning technology and the planning countermeasures, based on the analysis of the urban low-carbon development direction and the connotation of the ‘dual carbon’ goals. Combined with the characteristics of the territorial spatial planning in the new era, the response path of the territorial spatial planning under the goal of the carbon peak and the carbon neutrality is explored from four dimensions:the resource footprint accounting, the overall planning of the whole space, the multi-level effective transmission, and the full-cycle systematic supervision, focusing on the spatial structure optimization and the spatial governance.

In order to cope with the global climate change and to actively promote the development and the construction of ecocities, China has proposed the dual carbon goal of the carbon peaking and the carbon neutrality. By analyzing the background and the connotation of the dual carbon goal as well as the relevant theory and practice at home and abroad, this paper reviews the urban development strategies of the low carbon goal, then puts forward suggestions of the development strategy and the implementation path of the ecological city in the new period from the aspects of the space environment, the transportation, the low carbon industry, the energy resource recycling, the supporting system, among others.

The digital technology in the urban field provides a dynamic data information platform for the accurate acquisition and analysis of the spatial carbon source and sink data. The platform can improve the efficiency of all-factor control of the territorial spatial planning and promote the carbon emission reduction in the urban domain. By integrating the advantages of the multi-discipline, the multi-scale and the multi-probability, the digital technology can make full use of various models and sensors to update and run the data of each system anytime. The trajectory data mining in the digital technology of the urban spatial carbon emission is the development direction that needs attention, while the spatio-temporal trajectory mining of the urban carbon emission should focus on the system update, the spatial surface domain feature mining and the big data application. Based on the digital analysis method, it is found that the ecological vulnerability identification and the security pattern construction are the aspects that need to be focused on to establish the ecologically resilient urban space. Using the remote sensing technology to measure the carbon sinks of the same category will have errors due to different geographical features, and this difficulty deserves attention. The accurate measurement of the urban spatial carbon sinks in the future needs to be realized by combining macro and microscopic features and combining multi-platform and multi-temporal dynamic monitoring.

In the background of the "dual carbon" policy, to further clarify the summer thermal environment characteristics of the waterfront settlement in the cold areas of China, the Landsat-8 remote sensing images and the impact factors of 91 typical waterfront settlements in Tianjin, along with the correlation analysis and the multiple linear regression method are used to obtain the characteristics of the thermal environment. It is shown that the thermal environment regulation effect of the planar water is better than that of the linear water, with the difference of the UHI effect up to 1.57℃. The UHI effect has a significant positive correlation with the building density (BD) and the waterfront distance (WD), and is significantly negatively correlated with the average building height (H), the normalized difference vegetation index (NDVI), and the water surface ratio within a radius of 1 km (WR), with the NDVI and the WR having the highest influence weight. There are differences in the influencing factors of the UHI effect in the settlement with different building layouts. The lattice-type settlement has the lowest UHI effect, and the enclosed-type settlement has the highest UHI effect. When the BD is less than 19.08%, the thermal environment can be adjusted well by reducing the WD and increasing the WR. Finally, recommendations for the thermal environment improvement of the waterfront settlements in cold regions are made.

Against the backdrop of the severe global climate change, it is a consensus to achieve the goal of the carbon peaking and the carbon neutrality for the climate change mitigation. At the same time, building resilient cities is a new concept and a new way to adapt to the climate change. This paper reviews the studies of the low-carbon resilient cities in response to the climate change, focusing on the practical experience of the climate change mitigation and adaptation in Boston, the United States, Copenhagen, Denmark and Vancouver, Canada, including how to address the climate change through planning. The concept of the low-carbon resilience is proposed to be incorporated into China's territorial spatial planning system to provide a planning support for the realization of the dual-carbon goal and the resilience construction.

With the energy industry in mind, this paper analyzes the difficulties and the challenges of the energy industry enterprises dominated by oil and gas companies, including the training, the use, the evaluation and the incentive of scientific and technological talents under the background of the "dual carbon" goals and the digital transformation. On this basis, this paper proposes to establish a scientific and technological talent management system model, and puts forward suggestions and measures for the construction of scientific and technological talents in six aspects.
