喀斯特人地关系地域系统的结构与功能刍议─—以贵州民族地区为例

A tentative study on structure and function of man-land relationship areal system in karst terrains

人地关系的协调必须按地域类型进行。由于特殊自然条件的影响，喀斯特环境具有与非喀斯特环境大为不同的特殊地域结构和功能，其形成的主要原因是以碳酸盐岩为主的景观各组成要素间的相互作用和中小尺度地域分异规律的影响，其结果产生不同类型的地域单元并在空间形成有序结构，从而导致具有特色的喀斯特人地关系地域类型的形成。

The manland relationship in karst terrains should be coordinated according to the arealtypes. Owing to the effect of natural conditions,karst environment is different from nonkarstone in specifiC areal structure and function,It resuIts mainly from the interaction among thelandscapeconsisting elements(carbonate rock as predominant one)and from the effect of themiddle and small scale areal differentiation law. As a result,the areal units of different typesare formed,in turn,the ordered spatial structure is shaped.These lav the foundation forforming special areal system of man-land relationship.
