综述2008年,全国11条大江大河径流量:长江、黄河、海河、松花江、辽河、钱塘江、闽江均低于多年平均径流量,淮河、珠江、塔里木河、黑河均超过多年平均径流量;与2007年相比,长江、海河、珠江、辽河、钱塘江、闽江、塔里木河有所上升,黄河、淮河、松花江有所下降,黑河变化不大。各流域土壤侵蚀量:与多年平均侵蚀量相比,钱塘江没有变化,长江、黄河、海河、淮河、珠江、松花江、辽河、闽江、塔里木河、黑河均低于多年平均值;与2007年相 Summary In 2008, the runoff of 11 major rivers nationwide was lower than that of the average annual runoff in the Yangtze River, Yellow River, Haihe River, Songhua River, Liaohe River, Qiantang River and Minjiang River. The average annual runoff of the Huaihe River, Pearl River, Tarim River and Heihe River exceeded the average ; Compared with 2007, the Yangtze River, Haihe River, Pearl River, Liaohe River, Qiantang River, Minjiang River and Tarim River have risen, but the Yellow River, Huaihe River and Songhua River have declined, but Heihe River has little change. The amount of soil erosion in each basin: Compared with years of average erosion, there is no change in the Qiantang River, and the average value of the Yangtze River, the Yellow River, the Haihe River, the Huaihe River, the Pearl River, the Songhua River, the Liaohe River, the Minjiang River, the Tarim River and the Heihe River is lower than the annual average; Years of phase
