为了调查东北地区土壤侵蚀的现状,完成编制全国土壤侵蚀图的任务,我委应用了先进的遥感技术,在东北四省、区的共同努力下,从1984年到1987年,历时三年,现已编制出1∶50万分幅(40幅)土壤侵蚀现状图;查清了土壤侵蚀的面积数量及其分布范围.既摸清了水土流失底帐,又为编制国民经济发展计划提供了基本资料. 通过实际的调查表明,要完成东北地区124万公里~2这样大面积
In order to investigate the status quo of soil erosion in northeast China and to complete the task of compiling the soil erosion map of the whole country, our committee applied advanced remote sensing technology. With the joint efforts of four provinces and regions in Northeast China, from 1984 to 1987, it lasted for three years and now A map of soil erosion at a scale of 1: 500,000 (40 photos) has been prepared, and the area and distribution of soil erosion have been found out, which not only clarifies the base account of soil and water loss but also provides the basic data for compiling the plan for national economic development According to the actual investigation, it is necessary to complete such a large area of 1.24 million km ~ 2 in the northeast region
