摘要
随着北京市水土保持生态环境建设工作的深入开展,信息系统的建设已成为当务之急。利用GIS技术,根据水土保持治理及管理的需要,将北京山区划分成547条小流域单元;并在北京河流代码的基础上,制定了小流域编码。小流域划分工作的完成,为北京市山区水土保持工作数字化管理奠定了基础,为水土保持数据库的建设提供了基本管理统计单元。
Now information system of soil and water conservation is given more attention, as the development of soil erosion control.With GIS technology,Beijing mountain area was divided into 547 small watersheds based on the needs of erosion control and management.Each small watershed was given a code on the basis of river coding in Beijing area.Small watershed dividing work laid a foundation for data-base construction of soil and water conservation.
