| 摘 要： | 本文介绍了目前农用地定级工作中区位因素定量化处理的一般方法。针对目前区位因素定量化过程中存在的问题,如空间距离量算、阻隔与通道、衰减模型、定级区域外的区位因素等,提出了相应的改进措施,以使定级结果尽可能的符合现实。

Location Factors Quantification in the Development of Farmland Grading System |
| |
| Abstract: | The general method of quantifying location factors for farmland grading was introduced in this paper. In order to make the farmland grading more accurate, some measures are proposed for solving the problems occurred in the process of the location factors quantification such as the spatial distance calculation, the obstruct and channel, the attenuating model, and the location factors outside the grading area. |
