In this unique wetland environment , whole villages sit on floating islands on the lake 环境湖湿的此地是唯一把所有村庄都建在湖中浮土上的地方。
It is difficult to carry out geological mapping in some areas where are covered by quick soil or vegetation , or the demorhism there is acute 在浮土覆盖广泛、植被发育或者风化剧烈的工作区,地质工作往往很难进行。
Researching and summarizing an effective set of methods of field works and interpretation according to the southern area of china which has dip topography , thin soil and complicated geological circumstance 并就中国南方地区地形切割强烈、浮土较薄、地质情况复杂等客观实际,研究总结了一套行之有效的野外工作和解释方法。
