广西弧形山系作用下的环境差异

Environment Variation in Effect of Arc Mountains in Guangxi

广西地处中国三大阶梯地势的第一台阶向第二台阶的过渡地带,不仅山多,而且山系极具特色,尤其是特殊形态的弧形山系,对当地群众的生产生活产生着深刻的影响。采用数字高程模型(DEM)勾绘出广西弧形山系的位置和走向,分析山系对水、光、热分配格局的影响,创造性地绘制了广西水系树形图。同时,通过收集和整理各不同地理区域自然资源和经济社会情况,探索人类生产生活与自然环境相适应的规律,从地理区域的角度试探人类如何从大自然中获取最大的、可持续的生存基础,以求长足的繁荣和兴旺。

Guangxi is located in the Chinese three big steps and ladders topography the first stair to the second stair zone of transition. Guangxi not only has many mountains,but also has a lot of special mountains. Especially,the shape of arc mountains has the profound influence to the local populace＇s production and life. Using Digital Elevation Model（ DEM） to outline the position and the trend of Guangxi arc mountains and analyze effect of mountains on assignment pattern of water,light and hot,tree diagram of Guangxi river system was drawn up creatively. At the same time,through collecting and reorganizing natural resource and the economic society situation of different physiographic regions,the rule for which the humanity production and life and the natural environment adapted was explored. From the angle of physiographic regions,how the humanity in a big way to gain the sustainable survival foundation from the nature was probed in order to obtain considerable prosperity.
