GIS在土壤侵蚀分析中的应用研究进展

 土壤侵蚀模型是水土保持规划中的重要方法,目前常用土壤侵蚀模型缺乏对空间数据的有效管理,因此使得它们在实际应用中存在因子获取和结果分析不便的缺陷。GIS对空间数据管理分析独有的优势使得GIS在土壤侵蚀中已经得到了广泛的应用,目前主要集中在土壤侵蚀模型因子获取、模型运算和结果可视化分析3个方面。土壤侵蚀评价信息系统就是三者应用的综合体现。

Advance of GIS Applications in Research of Soil Erosion

Soil erosion models are technique tools for soil and water conservation. But soil erosion models have limitations in model factors achieving, model-operation and results analysis. GIS has been employed in soil and water conservation work, mainly focused on factor achieving, model-operation and visual results analysis. The combination of these three applications is soil and water conservation decision making supporting GIS information system. At the same time, the application of GIS in soil and water conservation still has problems such as accuracy, error, and applicability. With the development of GIS, these problems will be conquered; what's more, GIS will provide much more methods or thinking ways for soil and water conservation in modeling, model operation and ways of analysis and display.
