摘  要:
以郭家河小流域为例,在3S技术的支持下,采集和处理各类数据,建立小流域基础地理数据库。采用土壤侵蚀快速评估的方法确定土壤侵蚀强度,建立土地等级评价模型,评价分析流域内土地等级。确定总体规划目标,合理安排农、林、牧等各业用地,因地制宜地布设综合治理措施。3S技术的应用,使得整个工程实现了空间可视化、定量化与规范化。

摘  要:
The Guojiahe small watershed was used as an example. With the support of 3S technology,the data were collected and processed,and then a fundamental geographical database about the small watershed was built.Soil erosion intemsity was identified by the rapid assessment of soil erosion. Land grading was implemented by the land gradation evaluation model.After this,the goals of master plan,land size used for agriculture,forestry and animal husbantry are mapped out,and relevant control measures according to local conditions are formulated.With the help of 3S technology,the whole project can be carried out in a comprehensive way.
