The essence of planning disintegration is the disconnection of their objective system, indicator system, and spatial coordinate system. Few studies have been conducted on this issue. This paper analyzes the manifestations and causes of the "three-system dissociation," and proposes to establish a new objective system. In addition, it proposes to strengthen the connection design, aiming to explore effective ways to realize inter-planning connection and coordination.展开更多

The hologram is nonuniformly sampled by decomposing it into several parts with various sampling rates. The hologram is calculated based on the nonuniform fast Fourier transform （NUFFT） algorithm. In the experiment, we load this nonuniformly sampled hologram on phases-only spatial light modulator （SLM）, and by illumination with collimated light objects with different sampling rates are reconstructed at different distant planes simultaneously. Both of the numerically simulation and optical experiments are performed to demonstrate the feasibility of our method. The experiment also shows that our proposed nonuniform sampled hologram for multi-plane objects is calculated by only one step, better than conventional method that needs several steps of calculation proportional to the numbers of object planes.展开更多

Mianzhu is an example that is officially named as one of the pilot cities for multi-plan integration on the county level. The paper firstly analyzes the problems associated with multi-plan integration in Mianzhu, including the indeterminate hierarchy of the planning system, the disunity of technical standards, problems regarding spatial order, coordination and division of powers and functions, and the intensive utilization of spatial resources, the lack of a coordination mechanism, and low participation of experts and the public. Secondly, by learning from Germany's spatial planning, and also practical experiences of pilot cities for multi-plan integration in China, this paper creatively brings in the connotation of multi-plan integration on the county level, and further proposes a power division based on three-level planning system and three kinds of space, the reinforcement of a spatial order, intensive spatial utilization, and a planning coordination mechanism, hoping to provide reference to other cities.展开更多

In addition, it explores, from the perspective of planning compilation and implementation, a general multi-planning system integration means on the basis of spatial elements, authority management, and technical standards. It then summarizes the key outcome: one plan, database, coordination mechanism, and so on, discovering a new planning compilation and management approach for regional coordination, ecological coexistence, urban-rural interaction, and efficient resource utilization.展开更多

The real meaning of multi-plan integration is to put multiple plans in one framework for coordinated operation, within which city comprehensive planning should be more strategy-oriented and be considered together with other plans, such as spatial development at the city-region level and structural management at the city and township levels.展开更多
