摘要
应用GIS软件,结合研究区实际情况,选取了对间作模式影响较大、区域内变异明显,在时间序列上具有相对稳定性,与经济林和甜菜生产有密切关系的9个因素,建立评价指标体系。结果表明:高度适宜区面积15766 hm^2,占总面积16.19%,适宜区面积61640 hm^2,占总面积63.3%,勉强适宜区面积12155 hm^2,占总面积12.48%,不适宜区面积7805 hm^2,占总面积8.3%。
Combined with the actual situation and suitable planting economic forest intercropping sugarbeet regionalization, the data of 9 evaluation factors with large influence, obvious variation, and relative stability in time series were used to establish evaluation index system by geographic information system（GIS） technology software. Results showed that the highly appropriate area is 15766 ha, accounting for a total area of 16.19%,suitable area is 61640 ha, accounting for a total area of 63.3%, barely suitable area is 12155 ha, accounting for12.48% of the total area, and not suitable area is 7805 ha, accounting for 8.3% of the total area.
