摘　　要：我国西部是油菜的原产地 ,作物生长期内的气候特点 ,同春油菜的生物学特性恰相适应。春油菜作为冷凉气候区的优势作物 ,对西部多发的霜冻、冰雹等自然灾害有减避功能 ,其自我肥田固土效能和产品的工业开发增值潜势大于其它作物。菜籽油是最佳佐膳油和后备燃料油 ,菜籽饼是优质蛋白类饲料源 ,市场广阔。在西部开发中加大油菜生产比重和产品的高科技开发力度 ,可取得以农业发展促加工业发展的双重效果。在我国东部适粮西部适油的大生态格局中 。Western part of China is original place of rapeseed,where climatic character during the crop growth period is corresponding to the rapeseed biological characters.As a dominant crop in the cold region,rapeseed could avoid or reduce damage from frequently happened natural disaster,such as frost and hail damage.Still more,to plant rapeseed could make soil rich and prevent from soil erosion and products of rapeseed have potential explore effect compare to other crops.To add up rapeseed production and high technical explore power in west part of China will obtain bi effect in accelerating agriculture and industrial development.All of this result from adjustment of plantation construction,which encourage planting more grain crop in east and more oil crop in west.
