摘要
根据民族学和考古学资料进行的综合研究，可将苍洱地区居址环境划为４个历史变迁时期：４０００多年前的先民们居住在沿海拔２５００～２２００米一线的一些向阳避风的苍山台地上。海拔２２００～２０００米一线的苍山脚下为汉晋时期先民们的聚居点。海拔２０００米左右，沿滇藏公路一线的白族村落大致在唐宋南诏大理国时期形成。海拔１９７５米左右，今洱海边的白族村落大多数在元明清时期形成。其趋势是从高处往低处下移，随苍山上升，洱海水位下降，利用滩地形成新的居民群。其形成的间隔时间越来越短，加强洱海保护是迫切的任务。
The historical changes of the habitation environment in the area of Cangshan mountain and Erhai lake experience four periods according to the comprehensive study of the materials on ethnology and archaeology.Four thousand yerars ago,the ancestors lived on the terrace 2500-2200 meters above sea level on Cangshan mountain towards the sun and kept from wind.In Han and jin period,the area with an elevation of 2200-2000 meters at the foot of the mountain became the habitation.The Bai ethnic villages along the Yunnan and Tibet highway about 2000 meters above sea level formed under the control of Dali Empire at Tang and Song period.While those villages around the Erhai lake 1975 meters above sea level mostly came into being at Yuan,Ming and Qing dynasty.Whth the rise of Cangshan mountain and the decline of water table in Erhai lake,the trend of the changes is from high terrace to low areas.The interval of the form of habitations becomes shorter.It is a priority to strengthen the protection of Erhai lake.〖WTHZ]
