摘要
依据甘肃省各县年降水量、年蒸发量、平均湿度、无霜期、≥10℃年活动积温、极限低温、平均低温7个变量进行聚类分析。全省划分的埂坎利用的7个类型区为:白银庆阳北耐旱灌草利用区、兰州白银南庆中灌草利用区、定西临夏灌草乔利用区、平凉庆阳南天水北乔灌草利用区、甘南灌草利用区、陇南天水南乔灌草利用区、河西灌溉乔灌草利用区,并提出了各区适生的经济植物种类。
By means of sorting factors of annual precipitation, evaporation, frog-free period, accumulated active temperature over 10℃, average and lowest temperature, of each county in Gansu Province, terrace ridge/edge resources of the province is zoned into 7, namely, drought endurance shrub-grass zone of Baiyin and North Qingyang, shrub-grass zone of Lanzhou and South Baiyin and central Qingyang, shrub-grass-arbor zone of Dingxi and Linxia, normal arbor-shrub-grass zone of Pinling and south Qingyang and North Tianshui, shrub-grass zone of Garman, abor-shrub-grass zone of Longnan and south Tianshui, irri- gating abor-shrub-grass zone of Hexi. The suitable cash species for each zone are proposed.
