【摘要】 本文以实证分析的方法 ,以宁夏地区为例 ,通过研究该地区 2 0 0 3年 2 0 0户退耕户和 10 0户非退耕户之间 ,以及二者与 1999年实行退耕还林政策前的人均粮食消费量和人均食品支出水平的变化 ,认为退耕户的粮食安全程度比非退耕户和退耕前的农户有了显著的提高 ,这种提高与农民的人均收入水平和人均耕地面积呈正相关 ,而与粮食播种面积比重呈负相关 ,因而可以得出结论 :在生态脆弱地区实行退耕还林政策并不会影响当地农民的粮食安全更多还原

【Abstract】 The paper focuses on the difference in per capita grain consumption and per capita food-consumption between the 200 grain-for-grass farmers and 100 non-grain-for-grass farmers in 2003 and the base-level in 1999 empirically in Ningxia region.The paper gets to the conclusion that the food security level of the grain-for-grass farmers is much better than that of both the non-grain-for-grass farmers and the base-level, which is correlated to the farmers’ per capita income and per capita farming-area positively and to rate of the grain-farming area negatively. So we can say safely that the policy of grain for grass in the weak-eco area will not affect food security of local farmers.更多还原
