However, only a few research works have been done in giving assessment after the completion of renewal projects. Aimed at such a circumstance, this paper, by referencing the experience of European countries, establishes a multi-dimensional evaluation framework to analyze the primary data drawn from recent household surveys of Shichahai and Jinyuchi neighbourhoods in Beijing, and puts forward some suggestions based on the conclusions drawn from the surveys.展开更多
对北京什刹海北岸小石碑胡同工地西壁剖面沉积物粒度、化学成分及孢粉等相关数据进行综合分析,结果表明,从汉代至元代,什刹海有4个环境演变阶段的沉积物：1930~1820 a BP为河流相的分支河道、河漫滩沉积;1820~1295 a BP为湖泊沉积,其中...对北京什刹海北岸小石碑胡同工地西壁剖面沉积物粒度、化学成分及孢粉等相关数据进行综合分析,结果表明,从汉代至元代,什刹海有4个环境演变阶段的沉积物：1930~1820 a BP为河流相的分支河道、河漫滩沉积;1820~1295 a BP为湖泊沉积,其中三国时期（1730~1690 a BP）水域较大,水体较深,可能与车箱渠的修筑有关,此后逐渐退为湖滩;1295~970 a BP为河流相沉积;970~580 a BP为湖滩沉积,是当时什刹海北岸的边缘地带。孢粉组合反映低湿地植被的环境特点,符合该地区沉积物的环境背景特征。元代湖岸距当时的斜街约100 m,距今什刹海北岸约80 m。研究结果揭示了什刹海湖泊演变的历史,为什刹海环境演变研究乃至北京城区的历史地理研究提供基础性资料。展开更多
