摘要
本文在阐述了水土保持治理图编留原则、图面表示内容及表示方法的基础上,以淳化县泥河沟流域为例,利用彩色红外航片和野外调查补充,通过收集资料,选用地理基础底图、水土保持措施的分类与分段、位置及界线的确定,以及图例设计、清绘量算等过程,编制了此图。同时,指出了该流域今后的治理方向。
Based on the description of the mapping principles, the map contents and the mapping method,a map of soil and water conservation in the Ni-hegou Watershed of Chunhua county,Shaanxi province,as an example,was made by use of colour infrared aerial photograph and investigation data in the field.
