摘要
对某个树种适宜种植区域的规划要考虑到土壤、气温、降水量、海拔、坡度、坡向等立地条件对树木生长、开花、结果的影响。根据云南核桃对立地条件的特定要求,结合土地利用现状,遵循其中的关联规律,利用ArcGIS软件的叠加分析功能,查找出适宜规划的特定区域,做出分级评价,并制作出规划图。通过面积计算得到较适宜种植面积为4 556.6 hm2,适宜种植面积为75 079.65 hm2,可种植面积为12 123.46
It is necessary to consider the influence of soil, temperature, precipitation, elevation, slope, aspect and other site conditions on the growth, blossom, and resultant of trees for planting area planning. According to Yunnan walnut specific requirements of site conditions, combined with current situation of land utilization, followed the related law, based on ArcGIS software, this study fond out the suitable plan specific to the region by making classification evaluation, and plan map. Through area calculation, got suitable planting area of 4 556. 6hm2 , suitable cultivation area of 75 079. 65hm2 , planting area of 12 123.46hm2
