Community planning, especially with localized and practice-oriented characteristics, is now facing many limitations. These include aspects such as traditional urban planning techniques that mainly focus on space, a restricted research perspective, as well as basic planning theories that are mostly imported from the West. Using the perspective of socio-spatial dialectic for reference, this paper summarizes the evolution process of Chinese modern residential space planning and design from residential district planning under the planned economy system, to housing estate planning in the real estate development, and to community planning in the new era, presenting an important characteristic of transitioning from "producing space" to "production of space," with "society" gradually replacing "space" and returning to the goal of production. Based on the analysis on the main limitations and problems in the former work of community planning in China, the paper takes the practical exploration on community planning in the "New Qinghe Experiment" in Haidian District, Beijing for an example. Aimed at the prominent problem of an extreme imbalance between "urbanization of space" and "urbanization of population" in the current Qinghe area, the key objective, means, and technical path of new-type community planning are proposed, within which three significant transition features are demonstrated, including going from "need-oriented" to "capital-oriented," from "interest intervention" to "relationship intervention," and from "community construction" to "community building."展开更多

Discovery of the rocks is significant to re-recognize stratigraphic property of ＂Liaohe Group＂, regional geoteetonie location and revolution of orogenic zone in Qinghe valley of the northern Liaoning.展开更多
