The writer of the paper divides karst regions of South China into three most typical and basic kinds of man-land systems,namely,poor karst mountain areas,karst basins,town area in the valley and karst tourist areas. The division is based on the regional interconnections of different environments with different karst topographical structure,population composition,psychological behaviour,economic growth,utilization form of natural resources and living conditions.Through the discussion on the forming causes,developmental course,structural characteristics,and the present situatin of these three man-land systems,the author indicates that the ecological environment of the karst region in South China,which is one of the regions with a tense man-land relation,has come to the verge of ecological environment destruction because of unreasonable exploitation and utilization for quite a long time. Main solutions to the problems in differentkinds of man-land systems have been putforward at the end of the paper.
