基于GIS的皖西大别山区野生霍山石斛种植区研究

研究利用GIS技术分析野生霍山石斛独特生长地理环境，通过分析区域地形与气候差异，划分野生霍山石斛适宜种植级别。霍山县中南部因处于大别山脉转折处，地理位置独特，东北、西北向山坡极多，成为野生霍山石斛生长的最适宜区域；此区域西北、南部山丘东-西、南-北走势居多，适宜生长山坡相对较少；大别山主脉北部和东部年日照过少或过多，种植时需要人工处理光照；大别山边缘区域海拔较低，较难种植野生霍山石斛。

Research of Wild Dendrobium Huoshanense Planting Area in Dabie Mountain Based on the GIS

This research analyzes the unique geographical environment of Wild Dendrobium Huoshanense by using GIS technology and analyzing the regional topography and climate difference,and then divides planting level of Wild Dendrobium Huoshanense. Because the central and southern Huoshan County that locate in the turning point of Da?bie Mountain,and its unique geographical location with many slopes in the northeast and northwest,it has became the most suitable area for Wild Dendrobium Huoshanense growth.Its northwest and south Hill’s East- West, South-North trend is in the majority at this area,suitable growth slopes are relatively few;the duration of sunshine is too much or too little in the North and East of Dabie Moutain,it needs artificial treatment. Because the edge of Da?bie Moutain is at lower elevation,so planting Wild Dendrobium Huoshanense is difficult.
