材料二 2012年6月28日,世界品牌实验室在北京发布了2012年(第九届)“中国500最具价值品牌排行榜”,“北大荒”以品牌价值365.36亿元名列排行榜第38位,比去年提高4个位次,继续领跑中国农业品牌,向进军世界级品牌发起强有力的冲刺。

(1)东北稻米具有洁白清亮、口感细腻、产量稳定的特点,其成因有哪些?

(2)建设东北“中国大粮仓”有何重要意义?

(3)Q地的湿地开发,经历了从“北大荒”到“北大仓”,再从“北大仓”回到“北大荒”。从地理角度看,其从“北大仓”再回到“北大荒”的意义是什么?

答案

(1)水稻生长期长;夏季光照充足,昼夜温差大,有利于养分的积累;土壤肥沃;冬季低温,病虫害少。

(2)东北地区一直是我国重要的商品粮生产、粮食调运和商品粮储备基地,素有中国“大粮仓”和“粮食市场稳压器”之称。东北地区粮食的产量直接关系到国家的粮食安全,并影响着我国经济的健康发展与社会稳定。

(3)退耕还荒的意义主要体现在生态方面。从“北大仓”再回到“北大荒”,对于扩大湿地面积、保护生物多样性、调节气候、涵养水源等具有重要意义。
