Abstract： Major Function Oriented Zone (MFOZ), an attempt and exploration aimed at ecological civilization during China’s industrial civilization period which is divided into two stages, the stage of MFOZ planning and the stage of the national strategy and basic institution before and after the 18th Communist Party of China (CPC) National Congress, and the main characteristics of both stages are analyzed. Since the 18th CPC National Congress, the strategic thinking of the MFOZ has been deeply rooted in the hearts of the people, the strategic pattern of the MFOZ has been basically formed, the development of the categorized MFOZ has achieved remarkable progress, and the MFOZ mechanism has been initially established. It is proposed that the MFOZ will continue to play a greater strategic and fundamental role in the Chinese-style modernization. As a major strategy, plan and institutional arrangement for implementing the leadership of the Communist Party of China, giving full play to the advantages of the socialist system, and realizing modern spatial governance from top to bottom, the MFOZ should further strengthen the development and protection orientation towards land space, which is people-centered, with high-quality development as the primary task, and new development pattern as the strategic basis, MFOZ should expand new functions that meet the people’s aspirations for a better life and the national security needs, and rely on a sound spatial governance system to establish more precise MFOZ development guidelines and supporting policies.

Abstract： Improving carbon sequestration capacity through ecological construction is one of the important ways to achieve the goal of “carbon neutrality” in China. Based on the analysis of the current situation and trend of ecological carbon sequestration in China, this study summarizes the main challenges in the increment of ecosystem carbon sink in China. The current situation and trend, the significant carbon sequestration capacity of forests, the recovery phase of carbon sequestration capacity of grassland, and the carbon sequestration benefits of major ecological projects are also surveyed. Then, the new challenges of China are analyzed, including the backlog of over-mature forests affecting the carbon sequestration capacity of forests, the limited land area suitable for planting forests and grasses, the less diversified investment mechanism of ecological engineering, the imperfect supporting policies and measures for ecological carbon sequestration, and the increasing demand for forest products. To make sure the “peak carbon emissions” and “carbon neutrality” goals reached as schedule, the study points out that it is necessary to optimize the layout of ecological construction and to improve the capacity of ecological carbon sequestration through the optimization of the internal structure of ecosystem and the regional coordination of ecological construction. In terms of the optimization of the internal structure of the ecosystem, several policy suggestions are put forward: restarting orderly renewal and forests logging, enhancing the ecological carbon sequestration capacity of the grassland, and fully implementing the water diversion project on the western line. For example, some related research suggestions are proposed on forest management, including redesigning the forest regeneration route, conducting pilot programs in some forest areas, constructing modern standard system of forest logging, and improving basic facilities of intermediate cuttings. In terms of the land layout optimization of ecological construction, this study suggests that the government should establish an overall planning with differentiated regional carbon neutrality path, promote the coordination of regional ecological protection and clean energy, accelerate the improvement of ecological environment, and utilize national land space highly efficiently.

Abstract： “Double evaluation”, the abbreviation of the evaluation of resource and environmental carrying capacity and territorial development suitability, is the important basis and prerequisite for the implementation of spatial planning. This study systematically expounded the scientific concept, study framework, and research process of “double evaluation”, and discussed the core role in promoting the high-quality development of spatial development. This article firstly depicts the main development of “double evaluation” in MFOZ researches, including the proposal and improvement of the theoretical concept, the establishment of evaluation framework, and the application in MFOZ planning. Then, we analyze the main function of “double evaluation” and its irreplaceable fundamental role in optimizing spatial development pattern. As an effective means of cognizing land surface, “double evaluation” could provide the comprehensive and scientific understanding of regional background conditions as well as recognizing the prominent problems and major contradictions in spatial development. Based on it, the “double evaluation” would support basic materials for spatial planning compilation and guiding spatial planning implications by coupling various types of planning in different levels and supervising the implementation of planning. The limitations and proposals of the “double evaluation” are discussed to proper use it in actual work, which emphasizes that the adjustment of technical methods with local conditions and other basic work should also be taken into account. Meanwhile, we discussed the main features and problems of “Guidelines for the Evaluation of Resource and Environmental Carrying Capacity and Territorial Development Suitability (Trial)”, which was recently released by the Ministry of Natural Resources. Lastly, suggestions are made on the direction of improving and deepening the method and application of “double evaluation” in the optimization of spatial development pattern.

Abstract： Since the Third Plenary Session of the 18th Central Committee of the CPC, with the strength of eco-environmental protection, the deterioration of eco-environment in China has been curbed to a certain extent, which has led to discussions among decision makers on when China will reach the turning point of eco-environment. The judgement of the turning point is directly related to the eco-environmental protection strategies towards China’s two centenary goals. This study redefines the concept of eco-environmental turning point firstly, and then establishes an indicator system and an analysis framework to predict the time that turning point occurs. The results show that the turning point of eco-environmental quality based on routine monitoring indicators will occur around 2025, the turning point of eco-environmental quality based on public perception will come about 2035, and the turning point of eco-environmental quality considered some new factors such as emerging contaminants will achieve around 2050. To develop eco-environmental protection strategies towards China’s two centenary goals, it not only needs to make good plans for pollution prevention and ecological protection focusing on the current serious eco-environmental problems, but also needs to make good preparations for protracted battles aiming at eco-environmental problems that are currently difficult to solve, and potential eco-environmental risk in the future. During this process, in addition to further promoting the reform of the ecological civilization system, it is also necessary to make full use of science and technology in solving the “bottleneck” and “difficulties” of China’s eco-environmental problems.
