Urban Design Strategy Research Based on the Concept of Sponge City: A Case Study of Renbei District in Chengdu

Cities are currently confronted with many urban problems, such as water shortages, water quality pollution, floods, and the loss of habitats of aquatic organisms, and badly in need of a more comprehensive solution. In this context, the concept of "sponge city" is proposed. This paper, based on the theory of sponge city and low impact development, elaborated the origin, development, connotation, and construction method of "sponge city" concept. In this paper, the urban design scheme of Renbei District in Chengdu was taken for example to analyze the geographical environment and climate characteristics of Chengdu and explain the formation and verification of the scheme. It is considered that the "sponge city" is different from the traditional urban infrastructure. It is essentially an ecological approach. Its core is to build a cross-scale urban water ecological infrastructure to comprehensively solve the prominent water-related problems of urban and rural areas in China.

任北村铜器窖藏的族属及与“芮”“胡”相关的若干问题考论

1978年,在陕西省武功县苏坊乡任北村发现的窖藏铜器群分别来自三个不同的家族。结合出土铜器的形制、铭文及历史地理因素分析,楚簋时代早于其他器物,应是任北村窖藏的主人在后来得到。芮国本位于泾河上游,后迁徙至今陕西韩城附近,其家族成员长期为周王室的重臣,应在王畿拥有采邑。胡国或有二个:一在今河南漯河附近,一在今安徽阜阳附近,但可能并不存在姬姓胡国。任北村铜器窖藏有较大可能属于世代作为王室重臣的芮国,胡国的器物似是在某次与芮国的婚姻中作为媵器来到芮国的,芮、胡两国长期保持着密切的关系。
