摘　　要：小油桐是生物柴油的优质原料之一,经济和生态潜力突出,其生长对气象条件的依赖性强,为避免盲目引种,本研究以贵州85个气象观测站1961-2009年的气候资料为基础,结合野外小油桐实地观测资料,采用农业气象分析方法和地理信息系统(GIS)技术,对小油桐进行气候适宜性区划。利用年均温、>10℃积温、日照时数、极端最低温度及最冷月平均气温等指标确立了贵州省小油桐气候适宜分区标准。依托GIS技术空间分析功能,运用气候资源推算模式进行网格距为100m×100m以及精确到贵州乡(镇)的精细化气候区划,将小油桐种植划分为适宜、次适宜和不适宜气候区域。小油桐气候适宜生长区主要分布在南北盘江沿线,次适宜区主要分布在贵州省内中亚热带地区,不适宜区主要分布在黔中及黔北大部,研究结果可为贵州未来小油桐生产安全布局提供科学依据。As one of the most high quality raw material for biodiesel, Jatropha curcas has the natural advantages such as outstanding potential on economic and ecology, but their growth depended on meteorological conditions strongly. To avoid introduce blindly, the authors adopted the agro-meteorological analysis and geographic information system （GIS） technology, achieved climatic suitability division for Jatropha curcas, which based on observed meteorological data of 85 stations in Guizhou from 1961 to 2009, and combined with the data of field observation. According to the annual temperature （ Tmean）, 〉 10℃accumulated temperature （ ∑T）, sunshine hours （H） , extreme minimum temperature （Train） and the average temperature in the coldest month （ Tcold）, the regionalization standard of the climate suitability of Jatropha curcas was established in Guizhou. Based on GIS spatial analysis function, refinement climatic division which was under grid interval of 100m ~ loom and accurated to villages （towns） in Guizhou was finished. Jatropha curcas planting distribution,including suitable area, sub-suitable area and unsuitable area, was developped. The suitable area of Jatropha curcas was mainly located in south and north Pan River, the sub-suitable area was mainly distributed in the subtropical area of Guizhou, and the unsuitable area mainly focused on the central and northern Guizhou. The results could provide the scientific evidence for Jatropha curcas on work safety layout.
