土地类型系列制图的几个理论问题

ON SOME THEORETICAL ISSUES OF LAAN TYPE SERIES MAPPING

实际存在的不同尺度地域分异规律是土地类型系列制图的客观基础。多种尺度制图构成的土地类型系列制图可以全面揭示区域土地类型的形成因素、分布规律和空间结构特征，也为不同层次土地规划管理之间的相互补充、协调提供了重要基础。

Land classification,Series mapping,Resolution level,Terain differentiation,Mapping unit Abstract The Series mapping of land types is aimed to investigate thespatial structures of land withvarious scales and at various resolution levels. The really existing terrrain differentiation orders atvarious levels are the objective basis which makes it possible to map land types on separatescales,The land type mapping at each level has its mapping unit,mapping scale and serving pur-pose;and has its own land classification system also,The land type series mapping consisting ofmaps at various levels can comprehensively reveaI the formation factors,distributive order andspatial structure featrues of land types in a region.It also provides important bases for the inter-complement and inter-coordination between different level plannings and managements,A casestudy of land type serles mapping in Guizhou Province firmly verified the arguements mentionedabove.
