为阐明近年来西藏人均农产品占有量的年变化趋势 ,为未来西藏粮食安全提供科学依据 ,以1990-2012年西藏粮食、油菜籽、蔬菜和人口数量等指标的统计数据为基础 ,研究了主要农产品人均占有量的变化趋势.结果表明 :随着时间的变化 ,西藏粮食产量以2002年为界、出现先增加后降低的趋势 ;油菜籽和蔬菜产量呈现线性极显著增加趋势 ;随着人口数量和农产品产量的增加 ,西藏人均粮食占有量以2001年为界 ,呈现先增加后降低的趋势 ;人均油菜籽和蔬菜占有量呈现极显著增加趋势.因此建议西藏在进行农业生产结构调整时 ,应充分保证粮食作物的生产.

Food security played a substantial role in social stability and economic development .In order to under-stand the interannual variation trend of food per capita ,base on agricultural statistics data during 1990 to 2012 , the production of food ,rapeseed ,vegetable and population were analyzed .The results showed that the food pro-duction was increased before 2002 but decreased after 2002 ,the production was 608 280 t in 1990 ,and 983 970 t in 2002 ,905 330 t in 2009 .Rapeseed and vegetable production showed a significant increased in the linear trend ,the rapeseed production were 17 140 t in 1990 and 63 047 t in 2012 .The vegetable production were 84 545 t and 655 905 t in 1990 and 2012 ,respectively .But with a burgeoning population ,food production per capita was increased before 2001 ,but had a remarkable decreased after 2001 .The production per capita of rape-seed and vegetables showed a significant increased .The results suggested that food security should be pay high attention in Tibet .
