Constructing an ecological security pattern with closer ecological connections and less ecological disturbance is an important way to make contributions to the balance between ecological protection and economic development in national territorial planning. This paper aims to establish an ecological security pattern, which should take into account the coordination and protection of sources and corridors in the ecological system in an integrated manner. Taking 33 counties (districts) around Dongting Lake as examples, it puts forward the ecological pattern formed by the ecological essential source areas and natural corridors, and the urbanization pattern formed by economic society source areas and artificial corridors. Then, we reveal the spatial characteristics of the ecological positive points and ecological disturbing points between the ecological pattern and urbanization pattern, and offer artificial and natural countermeasures for the problems in particular areas of the ecological environment. The main conclusions can be drawn as follows: (1) There should be 1537 identified ecological corridors in the ecological security pattern and 908 key points urged to be protected, which takes up 0.48% of economic society areas for returning to the ecological core source area, so as to promote the spatial relationship between ecological elements; (2) There are 8800 ecological disturbing points, 1.36% of ecological essential source areas and 12.95% of the length of natural corridors are in disturbance. In order to collaboratively develop the natural and artificial systems, the interference areas should be managed by means of creating buffers, establishing an early-warning system, and so on; (3) Natural corridors of the first to third levels in non-essential patches can be measured as 203.22 km2, 125.67 km2 and 35.59 km2, respectively, which can be defined as protected area of future ecological security pattern separately to meet a continuous increasing demand for ecological protection land. The results can provide a reference for the coordination of ecological land and urban construction land in the national territorial planning system.
Since the territorial spatial planning is required to merge multi-planning, unify zoning, and implement baseline regulations by land functions, compilation of spatial regulation is significant for constructing and implementing the strategies and system of spatial regulation. Even though we can unify the zoning of multi-planning through the boundary lines of spatial regulation districts, three issues must be concentrated to coordinate multi-planning regulation and reinforce the binding of territorial spatial master planning regulation to special plans and site plans. First, implement spatial regulations with human behaviors as the objects to improve constraint on negative influences. Second, merge current ordinances into territorial spatial master planning regulations. Third, enhance the guidance and constraint of baseline control model to non-developing and constructing human behaviors. The current researches have studied the definitions and objectives of the territorial spatial planning regulations through legal principles, logics, zoning and policies, and attempted to compile the strategies and systems of the territorial spatial planning regulation as well. Meanwhile, some researches have studied the influence relations among human behaviors, natural resources and territorial space. However, they lack a discussion of the compiling thinking of regulation ordinance from the perspective of human behaviors, which is an indispensable factor supporting the implementation of territorial spatial planning. This research aims at establishing a compiling thinking of the territorial spatial master planning regulation based on the perspective of human behaviors. We coordinate the zoning and regulations between territorial spatial planning regulations and regulation ordinances with human behaviors as carriers, and infer the relevant regulations of territorial spatial master plan according to the impacts caused by human behaviors to ensure the targeted implementation.
Territorial spatial correction is an important means for the natural resources management departments to implement the "unified exercise of all territorial spatial control responsibilities" and is an important part of the control and governance. Based on the research on Yizheng city and Zhangjiagang city, this paper clarifies the type and cause of territorial space mismatch in the Yangtze River Economic Belt, and attempts to construct a implementation mechanism which aims to provide theoretical and practical reference for the construction of the national land use control system in the Yangtze River Economic Belt. The main conclusions are as follows: (1) The territorial space mismatch types mainly include: the mismatch due to unreasonable planning, lack of planning, and planning conflicts; the mismatch between urban, agricultural and ecological spaces; the industrial mismatch caused by labor, capital, land mismatch and environmental regulation requirements, the intensity mismatch caused by excessive use or inefficient use of resources. (2) For different types of mismatches, the research attempts to construct a territorial spatial correction mechanism from the following aspects, such as establishing the "three-line" coordination mechanism, building a "full process, multi-agent, multi-path" classification correction mechanism, improving territorial spatial use control system, establishing a comprehensive land improvement and ecological restoration mechanism and dynamic supervision mechanism. The results can provide theoretical and practical reference for the correction of territorial spatial mismatch, the control of land use and the optimization of territorial space in the Yangtze River Economic Belt.
As an important part of national spaces and resources, the waterfront resource due to its special location at land-water interface is gradually drawing the attention form the society. Because of the importance of Yangtze golden waterway, the waterfront resources along the Yangtze River has the great economic value, and its ecological value is becoming more and more prominent with the implementation of the Yangtze River conservation strategy. Starting from the concept and characteristic of waterfront resources, this paper builds the theoretical framework and indicator system which could evaluate the value of waterfront resources. Then the economic and ecological functional values of waterfront resources along the Yangtze River are assessed, with the exploration about the zoning control strategies and planning suggestions for waterfront resources. Aiming to enrich the natural resources theoretical systems, finally, this study provides assessment and planning references for the Yangtze Economic Belt and other parts of the country.
In recent years, the unification of territorial space use regulations has been upgraded to an unprecedented level of national strategic deployment, which is an extremely important reform task with overall significance. Based on the systematical review on the institutional evolution of territorial space use regulation since 1949, this paper puts an emphasis on summarizing the major features of previous territorial space use regulations in China. In general, we conclude that the key to implement territorial space use regulations is to control the three important aspects which consist of planning, licensing and supervision, to coordinate the utilization of continental space and ocean space and to discriminate the management of construction and non-construction purposes. On the premise of system construction, we propose four suggestions to institution on how to unify the territorial space use regulations: (1) Establishing a unified control line system for territorial space use regulations at the planning level; (2) Building an abundant and effective measure system for territorial space use regulations; (3) Constructing a unified and explicit regulatory system for territorial space use regulations at the supervision level; (4) Improving the legal system to help territorial space use governance at the support level.
