摘要
使用Maplnfo对丘北县扫描地图进行数字化，在乡镇尺度上关联了2002～2007年辣椒产量与种植面积数据。使用Maplnfo测量了各乡镇之间的直线距离与交通里程，计算了空间关联分维，结果趋于1，显示辣椒产业发展受山地地形的制约，城镇趋于公路等线性地理要素分布。通过丘北县辣椒产量等数据的图表化与可视化表现，发现树皮乡是主要辣椒生产基地，但单位面积产量并不高，表明该县辣椒产业仍有较大的发展潜力，提出沿树皮乡至天星乡等公路沿线实施无公害规模化辣椒种植发展格局。
By using Maplnfo to register and digitize the scanned map of Qiubei County of Yunnan Province, the capsicum yield data from 2002 to 2007 was related to the map. Using Maplnfo to measure the distance between different towns and the fractal theory to calculate the spatial correlation dimension, the result towards 1, this showed that it was constrained by a large mountainous area, the distribution of town system in Qiubei were towards the road. By graphing and spatialization of the capsicum yield data, it＇ s found that Shupi town was the major production base, but not the highest in the yield per unit area. So Qiubei still had great potential to develop the capsicum industry. A scaled distribution of nuisance-free cultivation of capsicum along the road from Shupi town to Tianxing was suggested.
