- 摘要:
- 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。
- Abstract:
- Food security played a substantial role in social stability and economic development.In order to understand 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 production 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 rapeseed and vegetables showed a significant increased.The results suggested that food security should be pay high attention in Tibet.
