| 摘 要： | 为找出秦安县苹果种植适宜区域等级,首先运用PCA方法确立了评价因子;再结合GIS空间分析功能确定了评价单元,最后借助ArcGIS和SPSS软件,实现了对其各乡(镇)苹果种植地适宜性的空间分等定级,发现高度适宜区主要分布在郑川、西川等河流低阶地、低黄土梁峁区,占耕地总面积的30.1%.

| Abstract: | To ascertain suitable apple-planting areas of Qin＇an, evaluation factors was established, and combined with the GIS spatial analysis function, evaluation units were determined by the PCA method. With the aid of the software ArcGIS and SPSS, the space classification and gradation of suitable appleplanting areas were implemented. The results show that the highly suitable areas mainly lie in low river terraces or low Liang Mao loess areas of Zhengchuan and Xichuan,which are 30. 1% of the total area of arable of Qin＇an. |
