浅析经棚传统聚落的形态特征

经棚地处于宗教文化繁杂但地域空间较为封闭的环境之中,因此保持了良好的地域特性,是草原地区独特的人文景观、宗教文化等信息的载体。文章以分析经棚传统聚落的历史形成过程为契机,对经棚传统聚落发展过程进行研究,探索其聚落形态演变的基本特征,以期对经棚聚落今后的发展提供指导依据。

Design and Construction of Removable DeepLitter Breeding Shed

The pig-on-litter system is characterized by reduced environmental pollution and high-quality pork. It has won the support of the government and the acceptance of market. It is urgent to develop the supporting facilities and products to promote the comprehensive promotion of this technology. Based on the climatic and hydro- logical conditions in Jiangsu Province, we designed the removable deep-litter breed- ing shed. Its construction costs were lower than that of ordinary water-flushed pig- gery. In addition, this breeding system would not consolidate the land. The indoor ventilation and heat-conservation performances also met the requirements by pig-on- litter system. The removable shed can be promoted as an important supporting technology for the deep-litter breeding model in the eastern China.

赤峰市西拉木伦河流域实测降雨量 径流量变化分析

文章以西拉木伦河流域内巴林桥水文站、大板水文站、万合永水文站、经棚水文站、乌丹水文站为主要控制站,根据各基本水文站的历年实测降雨量、年径流量为基础分析资料,分析计算赤峰市境内西拉木伦河流域降雨量、径流量的年际变化趋势,为西辽河水量调度提供技术支撑。
