吉林省粗饲料资源分布与草食家畜均衡发展的探讨

Roughage Resources Distribution and Balanced Development of Herbivorous Live Stocks in Jilin Province

对吉林省粗饲料资源和草食家畜的分布进行了调查研究。结果表明 :吉林省草原地区存在着严重的超载过牧现象 ,西北部草原地区超载 5 41 2 4万个羊单位 ,加速了草原的沙化、退化。然而各地区农作物秸秆资源利用率却很低 ,若利用率达到 5 0 %以上 ,东部山区和西部台地丘陵区仅秸秆资源尚有生产潜力 2 6 0 33万个羊单位 ,中部丘陵半山区和西北部草原区仍超载 484

Roughage resources and herbivorous live stocks distribution in Jilin province were analysed Results indicated that over grazing is so severe in the grassland region in the province with overloading about 5 4124 million sheep unit in northwest grassland region, speeding up desertification and degeneration of pasturein the region. However, the utilization rate of resources of crop residue were relatively low. It is estimated that there is 2 6033 million sheep unit producing potentiality if the utilization rate of crop residue increases to 50%. In middle mountain and hilly land region and Northwest grassland region there was about 4 8417 million sheep unit overloaded.
