Base on the climate condition of Yunnan Province, the norm of the climate zoning for Dalbergia sissoo Roxb. was confirmed. Supported with SPSS, a spatial analysis model for zoning norm was established by linear regression analysis for the meteorological data of Yunnan Province. The growth status of D. sissoo in Yunnan, such as tree height or diameter is reckoned by the 1 km×1 km grid, and a zoning for the appropriate area for planting D. sissoo was conducted. It indicated that according to the climate conditions, the area for planting D. sissoo should take 32.5 percent of the total area of Yunnan Province. The proportion of the area is as following: the most suitable area takes 0.7 percent, the suitable area takes 7.4 percent, and the sub-suitable area takes 24.4 percent. 根据试验点印度黄檀与气候条件的关系,分析确定了印度黄檀的气候区划指标。利用云南省的气象数据,在SPSS支持下,进行线性回归分析建立区划指标的空间分析模型。在GIS的支持下,按1 km×1 km细网格推算出云南省其它地区印度黄檀树高、胸径的生长情况,并对印度黄檀的适宜种植区进行区划,以气候因子为条件,得出云南省适宜种植印度黄檀的土地面积占32.5%,其中,最适宜面积占0.7%,较适宜面积占7.4%,一般适宜面积占24.4%。
