建立人工草地是维护陕北黄土高原生态平衡和发展畜牧业的战略措施

本文通过陕北草地资源的遥感调查,并结合该地区的生态变迁及畜牧业发展的历史与现状的资料分析研究认为,各种优良牧草具有分蘖力强,地面郁闭度大;根量大,在土层内能积聚大量有机物质;产量高,质量好等特点。因而在这里建立人工草地是保持水土,恢复生态平衡和发展畜牧业的战略措施。与此同时,还要处理好保护资源与开发利用、经济效益与生态效益和农牧林业之间的三个关系。

BUILDING ARTIFICIAL GRASSLAND,A STRATEGY FOR MAINTAINING ECOLOGICAL BALANCE AND DEVELOPING ANIMAL PRODUCTION AT THE LOESS PLATEAU OF NORTH SHANXI PROVINCE
