| 摘 要： | 基于冻土与湿地共生机制,运用大比例尺测图、钻探构建剖面、调查等手段,研究了大兴安岭北部宽谷地貌对沼泽发育的控制.发现宽谷属于箱型地貌结构,具有独特生态环境功能：地表水、冻土融水等构成多元供水系统,高纬-高海拔与冻土冷储构成冷控系统,共同构建寒湿环境,有利于沼泽发育,形成灌、草、藓、林4大类组成的沼泽复合体.宽谷腹部兴安...

| Abstract: | Based on the symbiotic mechanisms of frozen-ground and marshes,using large-scale mapping,drilling for soil strata and plant investigations,the effect of broad valley landform on the formation of marshes in the northern Da Hinggan Mountains was studied.It is found that the broad valley has a cube-type structure in landform,and has several important eco-environmental functions.Surface water,including meltwater from snow and ice and thawing water from frozen soil,converges into the valley bottom from both side... |
