摘 要:以太行山摩天岭为样区,以1∶5万地形图为底图,研制出了一种用平面图、剖面图与网络图相结合的绘制植被图的“双面图法”。用该法绘制的植被图,其正面为平面图和剖面图,背面为相对应的网格图。该图能对每种植被层片(或类型)和植物种的自然分布进行科学定位,能反映出各区域的土壤类型,并能显示出小区域的气候因子。By investigation and research of plant resources in Taihang mountain area, on the basis of our predecessors′job, we have made a new advanced mapping model of 1:50000 vegetation map. This model consults photograph of remote sensing:1:50000 photographic map is its basic map, plus environmental factors. A plane figure, a sectional drawing and a table have made the twosided map. Every species of natural plant is located scientifically in the vegetation map. A layer is the mapping unit. We can look quickly and accurately for growing area of specific plant and use it. The vegetation map is the informational storehouse in plant resources.
