遥感与地理信息系统技术在叙利亚沿海地区土壤侵蚀评价中的应用研究

在过去的几十年里，遥感与地理信息系统融合技术应用于土壤侵蚀评价的研究得到了显著的发展。本研究采用遥感资料、土壤和土地调查数据、数字地面模型和气象观测数据，利用地理信息系统技术来分别产生通用土壤流失方程（USLE）的各个参数，从而来评价水土流失量和空间分布状况。

Application of GIS and remote sensing in soil degradation assessments in the Syrian coast

Significant advance in the application of remote sensing and geographic information system (GIS) to assessing and solving soil and water conservation problems have been taken place over the last 10 years. This paper describes the procedures employed to integrate remote sensing and GIS techniques in an effort to characterize the spatial distribution of the risk of soil erosion by water on Latakia district, Syria. The universal soil loss equation (USLE) is used to calculate the annual soil loss rates for Latakia soils. Mainly, remote sensing data, soil survey, land use inventory, elevation data and climatic atlases are used as a resource data sets to generate USLE factor values. Integration of these data sets resulting in a map of polygons with unique combinations of USLE factor values.
