摘要
坡改梯是山区土地整理的最主要的工作之一,目的在于保持水土,改善生态环境,提高耕地质量。对于坡改梯,传统的研究方法只能建立在文字说明和图表统计的基础上,使用图件大多缺乏现势性,有很大的不确定性和笼统性,空间位置不明确。运用遥感和地理信息系统技术对都匀市的坡改梯适宜区进行了评价,充分运用了遥感和地理信息系统技术直观、快速的特点,在方法上有了一定的突破。
With the aims of keeing soil and water, improving the environment and field quality, fields in the slope ranging from 5 degrees to 25 degrees need to be terraced. Terracing is one of the most important work in field trans formation in mountainous area. In the past, people mainly use word and chart in terracing research. In this article we use RS and GIS which have the characteristics of directness and speediness.
