| 摘 要： | 目前新疆耕地盐渍土遥感调查常用方法为人工目视判读法.具体方法是:以土壤调查为基础,以盐渍土对农作物危害为主要解译标志,以地下水埋深为动态标志,进行综合解译判读;相应的解译指标为农作物的缺苗指标、农作物长势指标、地理景观特征、地下水位埋深等.新疆耕地盐渍土遥感调查结果得到了同行专家的认同,证明人工目视判读方法在新疆干旱盐碱地区是适用的.本文所提出的新疆耕地遥感调查盐渍土解译方法、标志、指标,在其它地区是否适用,需继续研究探讨.

| Abstract: | At present,the method of manual visual judgment is used in remote sensing investigation on saline soil of arable land in Xinjiang.It can be described as: with the investigation on soil as the basis,the hazard of saline soil to crops as the interpretation key,the depth of ground water as the dynamic symbol,to make comprehensive interpretation and judgment.The relevant interpretation indexes are the indexes of crop seedling missing,crop growth vigor,features of geographical landscape,depth of ground water,etc... |
