摘要
本文以华北地区某县水源保护区内化肥平均施用强度的计算为例,利用ArcGIS8.3软件中空间分析、属性表关联、属性表计算统计等工具,探索一种基于地理空间分析方法评估保护区化肥使用情况的方法。
Taking the case of the average chemical fertilizer application rate calculation in a water resource protection area of a certain county in north china as an example, this article investigated a method basing on geographic spatial analyst to assess the average chemical fertilizer application rate in water resource protection area with these tools of spatial analyst, joins and relates, and field calculator statistics in ArcGIS8.3.
