应用GIS及RS技术调查海滦河平原风蚀类型与盐碱土的分布

摘要

Taking the River Basins of Zhangwei, Tuhai and Majia as emamples, the technique of RS applied to the investigate the type of wind erosion in the area and the stength and distribution of alkaline and saline land were introduced and inquired in the paper. The analysis, calculation and result output of investigation content completed by application of the geographic data control as well as the space analysis and the function were also introduced in the paper.%以漳卫、徒骇、马颊河流域为例，介绍和探讨应用RS技术调查该地区风力侵蚀类型、盐碱土等的强度和分布、应用GIS的地理数据管理及空间分析和功能，完成调查内容的分析、计算、成果输出。
