简介:曾读过艾青的《北方》,无数次在脑中想象塞外的风沙卷去北方生命的绿色,疾奔而至的沙雾疯狂地扫荡大地原野,颓垣荒冢、孤单行路人,痛苦的呼吸挣扎着前进。伫立风中的诗人却深爱这北国荒漠中透着的尊敬,爱这记录着祖先荣耀的大地。或许要归功于三北防护林,也没准要感谢退耕还林的政策,艾青所描述的这一切悲荒景象我无一得见。恰恰相反,驱车从啥尔滨出发直至漠河的我,一路所见尽是松桦林与草原拼接成的绿海,是高不见顶的蔚蓝昱天,是天空中身姿百变的云彩,是安逸悠闲的村镇,是善实淳朴的居民。我想,或许比起艾青遇到的北方,我所经历的恐怕是天堂吧。在车轮上度过的5天,每见证一轮目出日落我都会沉淀几分对人生体悟,每走过一个村庄都会生出一些时代的叹息,我把它们写成5封信,致自己、致爱人、致父亲、致子女、致朋友。
