问题 单项选择题

自二十世纪末期,山西同全国一样粮食供需形势发生逆转,粮价持续走低,粮食生产效益滑坡,农民生产积极性受挫。2004年初,中央下发一号文件,实施了“一减三补”等一系列惠农政策,之后连续三年出台中央一号文件,“保护和加强粮食生产,确保粮食安全”被提到空前高度。山西省委、省政府一方面认真贯彻中央精神,加大财政支农力度,另一方面在引导农民调整、优化种植结构的同时,发挥资源优势,发展特色农业,推动农业产业化经营,促进了粮食生产的稳定发展。2004年全省粮食种植面积达到2925.4千公顷,比上年增加91.74千公顷,增长3.24%,加之风调雨顺的气候条件,全省粮食生产再次突破百亿公斤,达到106.2亿公斤。之后三年粮田面积稳定回升,2007年全省粮田面积达3173.21千公顷。2005年尽管遭遇严重旱灾,全省粮食总产仍达到了97.8亿公斤的较高水平。2006年全省粮田面积达3521.45千公顷,全省粮食总产达107.33亿公斤,预计2007年粮食总产可达105亿公斤。十六大以来的五年间,全省粮食生产总量达512.22亿公斤,年均粮食生产总量达102.44亿公斤,这标志着山西粮食综合生产能力稳定迈上百亿公斤台阶。
