长春伊通河东安屯一带晚霞
Changchun

     伊通河流域现有耕地面积为201091公顷(流域面积即农安3519.7平方公里+伊通1666.2平方公里+东丰151.5平方公里+长春郊区69533公顷÷3,理由是河道、废弃地、耕地各占一)。在伊通河调研,发现7000年的伊通河流域农业开发史上,写着一串串让人惊叹的数字,1949年玉米亩产为169斤,1987年已达502斤;水稻1949年亩产204斤,1987年为384斤,今天,还要更多,这是科学的发展,农业文明的起步。同时又有了一组数字令人焦虑:伊通河上游的伊通县,1945年全县林业用地占总面积的47.81%,1961年毁林开荒,25度以上荒山坡开垦为农田,全县林业用地为133.97万亩,占总面积的35.91%。“文化大革命”以粮为纲,毁林开荒现象再度出现,10年间毁掉林地约7.5万亩,1974年伊通县林业用地118.19万亩,占总面积的30.92%,成林变成幼林、疏林,伊通河护岸护堤的4.4万亩柳条通,全被垦为农田。由于伊通河两岸林地的减少,涵养水源的资源匮乏。伊通河再不见“两岸林木如篦,游鱼如梭,行三丈二尺宽大船”的景象。而在下游的农安县伊通河沿岸,据民国初期县署文件记载:“伊通河两岸从亮衣门到喇叭营子,长200里,宽里许,长满柳灌木,每年夏季,水清柳绿,鸟语花香,景致宜人。”伊通河支流万金塔小苇子沟两岸尤为茂密。直奉战争期间,农户为躲避官兵抓车,常有上百辆大车,几百匹牲畜隐藏于柳通内。
