本文利用 ARC/INFO 系统探讨了腾冲地区土地类型图编制的原则和方法,即先采用要素叠加法产生综合土地单元图,然后依赖计算机派生土地类型图,再将类型图划分为8个一级类型和62个二级类型.最后在数据分析基础上,给出了该区土地构成的基本特点.
In this paper, the principle and method of land type map compilation in Tengchong area are discussed using ARC / INFO system, that is, the first step is to generate integrated land unit map by element superposition method, then relying on computer derived land type map, and then the type map is divided into eight first-level types And 62 second-level types.Finally, based on the data analysis, the basic characteristics of the land formation in this area are given.
