In this paper, consideration is given to the finite element method solution of transient flows in prismatic open channels.In order to improve the understanding of this phenomenon, a mathematical formulation based on one-dimensional Saint-Venant equations is presented to describe free surface wave propagations in open channels.

土地集约利用下的乡村地域转换郊野公园研究
城市边缘区乡村地域转换郊野公园,存在一定数量的存量建设用地,其中主要为宅基地和工业用地.本文首先从城市边缘区乡村地域转换郊野公园面对的土地问题入手,分析宅基地、产业发展和农用地使用三方面所面临的主要问题.其次,从土地整治和增减挂钩、造血机制和生产要素集约、组团发展和长效管理三个角度探讨土地集约利用背景下的城市边缘区乡村地域转换郊野公园.最后,以洛阳周山郊野公园规划为研究对象,将基地融合到整个城市的

创新驱动or土地驱动:城市经济增长模式的时空分异--基于全国179个区县的分析
创新驱动和土地驱动是城市经济增长的主要驱动力,在城市发展的不同阶段,城市的不同空间,这两种驱动力对经济增长的影响是不同的.本文以专利申请数量表征创新驱动的城市增长;以土地招拍挂出让行为表征土地驱动的城市增长.选取我国15个城市的179个区县进行实证分析,得到了如下重要结论:①土地驱动的城市增长是低效的;②土地面积为300-500km2的区县创新驱动和土地驱动都很显著;③在城市功能拓展区、城市新区创
