National territory spatial planning is a guide for national spatial development, a spatial blueprint for sustainable development, and an important starting point for improving the modernization of the national spatial governance system and governance capabilities. Therefore, it is essential to promote the effective implementation of national territory spatial planning. Planning transmission is a key link to ensure the implementation of national territory spatial planning. There are several reasons for problems in the compilation and implementation of national territory spatial planning. Due to the lag of planning theories and methods, and the limitations of local practice, existing research results emphasize the vertical transmission of rigid constraints, functional zoning, spatial elements, etc. People are currently inadequately considering the transformation of space governance in the New Era, the unification of administrative power management boundaries, and the accuracy control of the transmission of spatial elements, which has led to the defect in transmission of technical ideas for national territory spatial planning. This article is based on the preparation and pilot practice of Guangzhou's land and space planning, starting with the transformation of governance at the conceptual level, the matching of government duties at the system level, and the management of elements at the technical level, to explore the integrating spatial governance into planning transmission, the rigid constraints of national will and the flexible guidance of local competitiveness, and the intensity and precision of administrative control at different spatial scales. The paper points out that planning transmission should adopt technical ideas such as two-way feedback, power and responsibility list, rigid and elastic combination, scale tolerance, dynamic balance, etc., to solve the key issues of planning transmission between different levels of master plans, and between master plans and detailed plans. It further proposes that planning conduction is not simply a "top-down" vertical conduction, but should also include "two-way feedback" in response to local development demands and specific field regulations, and a rigid conduction mechanism must be used to transmit strategic intentions downwards. When dealing with the relationship between the government and the market, it is necessary to strengthen flexible control and guidance to enhance the flexibility and adjustability of planning; in terms of the transmission of spatial elements such as land zoning, control line delineation, special facility layout, etc., administrative control of different spatial scales should be grasped through the process of adapting the space from overall blur to partial clarity, from structure to map spots, from partition to plot, from demarcation to delineation, to clarify the tasks, permissions and control accuracy of each level of planning. Follow the dynamic balance principles of "constant scale, variable form", "constant standard, variable location" and other dynamic balance principles to allocate space resources in a reasonable and detailed manner to cope with the dynamic changes of the influencing factors of the planning and layout plan during the implementation process, so as to finally realize the ecological environment. The comprehensive balance of civilization and urban economic development, rigid constraints and flexible adjustments, refined management and fuzziness. The results can provide research support for improving the national territory spatial planning system in the era of ecological civilization and promoting the effective implementation of planning.

Territory spatial pattern plays an important role in coordinating regional protection and development. Its basic premise is to clarify the connotation of territory spatial pattern and build a scientific and effective conduction path of territory spatial pattern. Based on the logic lines of "raster-land category-administrative region-whole area" and "suitability evaluation-territory spatial reconstruction-dominant function identification-regional consistency abstraction", this study develops a research framework for territory spatial pattern scale decomposition and conduction path. Firstly, the suitability of territorial space is assessed in terms of three aspects: ecological protection, agricultural production, and urban construction, with the type, intensity, and spatial pattern of territory spatial potential conflict identified using a model for identifying territory spatial potential conflict. Secondly, the "rigid constraint" and "elastic guidance" planning mechanisms are applied to mediate potential conflicts in territorial space and reconstruct the territorial spatial pattern. Finally, the location entropy model is utilized to determine the dominant function of territorial space and to establish a strategic plan for territory spatial development. Dongying city is used as an example in this research to conduct an empirical study. The results show that: (1) The territory spatial suitability of Dongying is crucial for ecological protection, suitable for agricultural production and urban construction, and the potential conflicts of territorial space are mainly moderate. (2) Ecological space, agricultural space, and urban space are all part of the territory spatial reconstruction. From coastline and coastal areas to inland regions, the boundary between protection and development in geographical units is 19.69 km and 1.6 km, respectively. The proportions of territory spatial reconstruction patterns, on the other hand, vary substantially between counties (cities and districts). (3) Dominant function zones include important ecological function zones, agricultural production zones, urbanization development zones and elastic development zones that provide differentiated control strategies for zoning classification. (4) The ecological protection pattern of "one heart, one screen, and one corridor", the development and utilization pattern of "one circle and two districts," and the flexible development pattern of "two belts" comprise the strategic pattern of territory spatial protection and development, which establishes the goal of sustainable territory spatial utilization. The findings of this study can be used as a guide for developing territory spatial planning and coordinating the effective allocation of regional territory and resources in the New Era.

As a key content of the city-level territory spatial planning system, the vertical hierarchical transmission of core indicators is of great significance to the optimization of the municipal territory spatial utilization pattern and the overall planning. Considering the inadequate and imprecise research of current index transmission, following the research idea of "core transmission index selection→logical index transmission technology construction→ multi-scenario simulation prediction", this paper takes Changde city as an example to study its core indicators transmission of territory spatial planning in 2035 "City→ District (County)" conduction. The results show that: (1) Based on the technical transmission logic of "indicators global total prediction-spatial layout simulation-regional classification transmission", through the comprehensive utilization of SD and GeoSOS-FLUS model, the core indicators of city-level territory spatial planning can be transmitted effectively and scientifically by combining "top-down" and "bottom-up" processing. (2) The SD model of "human-land-industry" coordination of land space utilization in Changde was constructed to obtain the total number of core indicators for territory spatial planning of this city in 2035, and the corresponding comprehensive benefits of territorial utilization will reach 1299.425 billion yuan, an increase of 207.75% compared with 2018. (3) From the indicators transmission results, the social and economic indicators of each county (county-level city, district) of Changde will maintain an overall growth trend except for the size of permanent residents in 2035. The boundary indicators will achieve "only increase but not decrease". The changes in land use indicators vary, but they are generally in line with the main body of Changde. The direction of the construction of the functional area, and the core indicator transmission results are in line with reality.

Planning zoning is a new zoning level proposed by the unified land and space zoning management and control system to make up for the lack of structural management and control at the meso-micro scale. The research on its technical methods is of great theoretical and practical significance. Based on the analysis of the requirements of "shrewdness", "accuracy" and "refinement" of spatial governance and the comparison of spatial zoning methods with different zoning logics, this paper studies and constructs a zoning method combining qualitative and quantitative methods from the development law of the main function "point axis" by using technical methods such as spatial analysis, multivariate statistics and weighted Voronoi diagram. In addition, this paper conducts an empirical study with Huangmei as a case. The research shows that: (1) The method in this paper can effectively delineate the zoning units in line with the connotation of primary planning zoning in the "Guidelines for the Compilation of Municipal Land and Space Master Plan (Trial)", which makes up for the lack of planning zoning methods. (2) Relying on the "top-down" zoning logic of functional development structure, the connotation of spatial structure management and control is effectively integrated into the planning zoning, realizing the guidance and management of spatial structure. (3) Through the weighted Voronoi diagram model, the optimal function orientation of space is identified, which improves the scientificity and technicality of planning zoning.
