GIS具有强大的空间数据和属性数据的处理能力。将GIS技术运用于农用地分等,不但可以减少大量繁琐的计算工作,而且可以大大提高分等的速度和准确度。以GIS为基础,宝鸡市太白县的农用地分等结果为例,阐述农用地分等过程并且实际分析太白县农用地多集中在9等地和13等地的原因。
GIS has a strong spatial data and attribute data processing capabilities. Applying GIS technology to agricultural land grading can not only reduce a great deal of tedious calculation work, but also greatly improve the speed and accuracy of grading. Based on GIS, the result of agricultural land classification in Taibai County of Baoji City is taken as an example to illustrate the process of agricultural land classification and to analyze the reason why farmland in Taibai County is mostly concentrated in 9, 13 and other places.
