湖南省粮食安全评价及影响因素分析

湖南作为我国粮食主产区,其粮食安全状况对区域乃至全国粮食安全具有重要的影响。综合考虑粮食供给、粮食消费、粮食储备和粮食外调因素,构建＂粮食安全指数＂来衡量区域粮食安全状况,并对湖南省的粮食安全状况进行测算,结果表明：湖南省1996—2009年的粮食安全水平处于基本安全及以上等级。人均耕地数量、单位耕地产出水平是影响湖南省粮食安全的主要因素,粮食消费量、粮食储备量和粮食外调量相对稳定,对粮食安全的影响不明显,但在未来可预见的时期内,这些因素的影响程度将明显增加,需要制定科学合理的粮食安全保障政策。

Analysis on the Assessment and Influencing Factors of Food Security in Hunan Province

Hunan province is China＇s major grain producing areas,and its food security situation has an important influence on the regional and national food security.Considered of the factors of food supply,food consumption,food reserves and food redeployment,this paper builds food security index to measure the regional food security situation,and estimates it in Hunan province.The results show that the food security level of Hunan is in above the basic safety from 1996 to 2009.The amount of cultivated land per capita and level of output per unit of cultivated land is the main factors affecting food security in Hunan province.The food consumption,food reserves and food redeployment is relatively stable,which impact on food security is not obvious.But in the foreseeable future period,the extent of the impact of these factors will significantly enhance.We need to formulate the scientific and reasonable food security policy.
