根据多年实地考察和收集的气象资料 ,分析了黔西北立体气候的基本特征、气候要素垂直分布规律、气候垂直分布类型的气温指标 ;在此基础上 ,论述了核桃、板栗、天麻、半夏、杜仲、党参、五倍子等的开发前景和途径 ,为这些林木、药材开发提供科学依据。指出在黔西北地区 ,核桃分布在海拔 80 0～ 2 4 0 0 m区域 ,适宜区为东部海拔 12 0 0～ 2 0 0 0 m,西部海拔 180 0～ 2 2 0 0 m ;板栗分布在海拔 6 0 0～ 2 2 0 0 m,适宜区为东部海拔 80 0～ 12 0 0 m,西部海拔 130 0～ 180 0 m ;党参适宜海拔范围 14 0 0～ 2 2 5 0 m ,杜仲适宜海拔范围 12 0 0～2 4 0 0 m,天麻适宜海拔为 12 0 0～ 2 0 0 0 m。
Based on many years of field investigation and collection of meteorological data, the author analyzes the basic characteristics of stereoscopic climate in northwestern Guizhou, the vertical distribution of climatic elements and the temperature index of the vertical distribution of climatic conditions. On this basis, Eucommia, Codonopsis, gall and other development prospects and ways for these trees, herbs provide a scientific basis for the development. It is pointed out that in northwestern Guizhou, the walnut is distributed in the altitude of 800 ~ 24000 m, the suitable area is 1200 ~ 2000m in the east and 180 0-220m in the west, 6 0 0 ~ 2 2 0 0 m. The suitable area is 80 0 ~ 1200 m in the east and 130 0 ~ 180 0 m in the west. The suitable altitude for Codonopsis is 140 ~ 255 m, 12 0 0 ~ 240 0 0 m, suitable for altitude Tianma 1200 ~ 2000m.
