摘　　要：以罗汉果主产地桂林市永福县龙江乡、临桂县茶洞乡农业气象条件为标准,通过分析罗汉果各个生长期的农业气候条件,利用GIS系统和已有站点的气象资料,对桂林市罗汉果种植区进行农业气候区划,为扩大罗汉果种植提供科学依据。结果表明,罗汉果适宜栽培于海拔200～600m的向阳山地,喜潮湿气候,怕渍水,在山坡地中间地带种植品质最好;利用数学统计模型,考虑地形分布情况,实现了桂林市基本气候资料细网格内插,农业气候区划精细到200m×200m;划分出桂林市最适合、适合、不适合种植罗汉果的区域,与实际种植情况相吻合。Siraitia grosvenorii is special agricultural product in Guilin City.The present study was undertaken in agricultural climate conditions of Longjiang Township of Yongfu County and Chadong Township of Lingui County.The agricul-tural climatic condition of Siraitia grosvenorii during all growth periods was analyzed,and geo-information system（GIS） and existing climatic data were used for the agricultural climate regionalization of growing areas for Siraitia grosvenorii,which provided scientific evidences for extending Siraitia grosvenorii.The data indicated that the plants can be suitably planted in the subtropical climate zone of mountain areas which side turned towards the sun at a 200-600m altitude.The Siraitia grosvenorii plants prefer warm,moist,and foggy climate,difference in day-night temperatures,short-day sunshine and high temperatures and dislikes waterlogging.Their quality was found the best when planted in the intermediate region of hilly land.By using GIS system and mathematic statistical model,fine grid interpolation of basic climate materi-als of Guilin City was comprehended and agricultural climate regionalization of small grid points（200×200m）was calculated for accomplishing the division of climatic areas.Further,the optimum,suitable and unsuitable areas for planting Siraitia grosvenorii were divided,which were the same as matter of fact.
