为了解河北省粮食安全现状以及草食家畜的节粮潜力,应用2008年河北省统计资料和相关文献的数据,计算了河北省粮食产量及消费量,并根据粗饲料产量,计算了河北省草食家畜的节粮潜力。结果表明:2008年河北省基本粮食需求占当年该省粮食总产量的45%,生猪和家禽饲养耗粮占粮食总产量的57%,粮食生产已不能满足粮食消费需求。加上工业用粮增加、人口增长、城镇化率上升和耕地面积减少,河北省粮食安全压力与日俱增。通过对河北省粗饲料供给量的统计和载畜量的计算,发现作物秸秆和饲草等粗饲料资源还有较大的开发空间。在粮食产量增幅有限的情况下,充分利用尚未开发的粗饲料资源发展草食家畜生产,每年可节约粮食近765万t,占河北省2008年粮食产量的26.32%,对缓解河北省粮食生产压力、优化城乡居民食物结构和确保粮食安全具有重要意义。
為瞭解河北省糧食安全現狀以及草食傢畜的節糧潛力,應用2008年河北省統計資料和相關文獻的數據,計算瞭河北省糧食產量及消費量,併根據粗飼料產量,計算瞭河北省草食傢畜的節糧潛力。結果錶明:2008年河北省基本糧食需求佔噹年該省糧食總產量的45%,生豬和傢禽飼養耗糧佔糧食總產量的57%,糧食生產已不能滿足糧食消費需求。加上工業用糧增加、人口增長、城鎮化率上升和耕地麵積減少,河北省糧食安全壓力與日俱增。通過對河北省粗飼料供給量的統計和載畜量的計算,髮現作物秸稈和飼草等粗飼料資源還有較大的開髮空間。在糧食產量增幅有限的情況下,充分利用尚未開髮的粗飼料資源髮展草食傢畜生產,每年可節約糧食近765萬t,佔河北省2008年糧食產量的26.32%,對緩解河北省糧食生產壓力、優化城鄉居民食物結構和確保糧食安全具有重要意義。

To elaborate current status of food security and grain-saving potential of herbivorous livestock in Hebei province,grain production and consumption were calculated based on the statistical data of Hebei in 2008 and related digital data.The grain-saving potential of herbivorous livestock was estimated on the basis of the output of natural grassland,artificial grassland,crop straw,silage maize,fallow field and tree leaves.The results showed that the basic grain demand accounted for 45% of the total grain output of Hebei province in 2008,and grain consumption of poultry and pig accounted for 57%.Grain consumption for industrial purpose was gradually increasing.At the same time,population was increasing,urban rate was rising,arable land was reducting but the growth potential of grain yield was limited.Food security faces a formidable challenge in Hebei.Developing herbivorous livestock production,is an effective approach to maintain and increase grain production by fully utilizing all crops straw and fodder resources such as forage,corn stalks,wheat straw,etc.Nearly 7.65 million t grain could be saved if the untapped roughage resources were exploited.The grain-saving livestock raising pattern could effectively ease the pressure on grain production,optimize food structure of urban and rural residents and ensure the food security in Hebei Province.
