natural resources of Changjiang zhongxiayou plain
ehangiiang zhongxiayou Pingyuan ziran ziyuan长江中下游平原自然资源(natural resou职esofChan却ang而d山e一助wer plain)长江中下游平原位于黄淮海平原以东，江南与东南沿海山地丘陵以北，长江三峡以东地区。主要由长江及其两岸支流冲积而成，包括江汉平原、洞庭湖平原、都阳湖平原、皖中沿江平原、里下河平原及长江三角洲平原，大部分地区海拔低于50米，面积约20万平方千米。全区位于亚热带范围，年均温14~18℃，1月均温O~5.5℃，7月均温27~28℃;年降水量1(XX)~1500毫米，比华北平原多1~2倍，季节分配较均匀;无霜期Zro~270天，〕ro℃积温达45(X)、5以叉)℃。作物可一年两熟，长江以南可发展双季稻连作的三熟制。土层深厚，有机质含量丰富，水田占耕地面积的70%左右。江河沿岸稍高处，土质疏松，排水良好，适宜棉田早作，是中国最重要的粮棉油生产基地。 长江天然水系及纵横交错的人工河渠，使这里成为中国河网密度最大的地区，平均1~2千米/平方千米，其中杭嘉湖平原高达12千米/平方千米。境内湖泊星罗棋布，是中国淡水湖泊分布最稠密地区。中国5大淡水湖泊中有4个分布在这里。它们是都阳湖、洞庭湖、太湖、巢湖。其中太湖地区共有大小湖泊(大于0.5平方千米)189个，水域面积占总面积的8.%%，高于全国湖泊率(0.83)的10倍。湖沼地区有丰富的水生生物资源，是中国水生动植物分布最广、产量最丰的地区。保存有中华鳃、扬子鳄、白暨豚等珍稀动物。 平原境内长江干流及其众多的大小支流，河长水丰，汉江等河段落差大，适宜建水电坝址，进行多级开发。宜昌至河口段水能蕴藏量为4944.5万千瓦。尤以湖北省境内各河段水能资源格外丰富，长江和汉江过境流量800亿立方米，水能蕴藏量达40以〕万千瓦，仅次于川、滇、藏，居全国第四位，且各水系流域雨季时空分布不一，修建电站可借助长江、汉江丰枯期的先后，进行相互调剂补偿。矿产资源不多。鄂东大冶、宁(南京)芜(湖)及湘中涟源一带分别是中国著名铁矿和锰矿分布地区。(冯嘉苹)
