摘要
为了探讨西南桦在云南的气候适宜种植区域，利用云南130个气象台站1961-2010年气候资料，采用GIS技术插值分析得出1 km ＆#215;l km气候要素网格图，依据8个气候指标划分出西南桦种植的最适宜、次适宜和不适宜区，给出了区划专题图。结果表明，西南桦适宜区主要位于泸水县、永平县、景东县、新平县、建水县、砚山县、丘北县、罗平县共同构筑成的分布北线以南地区；滇南、滇西南和滇东南海拔1100-1600 m的山区，是西南桦重点造林区域。
According to the requirements of growth and development on climate conditions of Betula alnoides, the indexes of climate division were identified, in order to explore climate ecological adaptable region for Betula al-noides plantation.The division indexes were worked out on small grid of 1 km ＆#215;1 km by GIS, which gave out dif-ferent values under different geographical conditions, base on the climate data from 1961 to 2010 recorded by the 130 weather stations in Yunnan province. Based on 8 climate indexes, special analysis and multi-overlapping method of GIS, the climatic regionalization of the most suitable, suitable and non-suitable regions for Betula al-noides was done.The result showed that the suitable regions in Yunnan are located to the south along the line made up by lushui county, yongping county, jingdong county, xinping county, jianshui county, yanshan county, qiu-bei county and luoping county;and the area of south Yunnan, southwest Yunnan and southeast Yunnan, which lo-cate at the altitude from 1 100 m to 1 600 m, are very important region for developing Betula alnoides plantation.
