综述2010年,全国11条大江大河径流量:长江、淮河、松花江、辽河、钱塘江、闽江、塔里木河、黑河径流量均高于多年平均径流量,黄河、海河、珠江径流量低于多年平均径流量;与2009年相比,除黑河下降外,其他各流域径流量均有较大增长。各流域土壤侵蚀量:与多年平均侵蚀量相比,松花江、塔里木河、黑河年侵蚀量有所增加,其余各流域均低于多年平均值;与2009年相比,淮河、松花江、黑河变化不大,其他各流
Summary In 2010, the runoff of 11 major rivers nationwide was large: the runoffs of the Yangtze River, Huaihe River, Songhua River, Liaohe River, Qiantang River, Minjiang River, Tarim River and Heihe River were both higher than those of the average annual runoff. The runoff of the Yellow River, Haihe River and Pearl River was lower than Average annual runoff; Compared with 2009, except for the decrease of Heihe River, the runoff of other watersheds also increased greatly. Soil erosion in each basin: compared with years of average erosion, annual erosion of Songhua River, Tarim River and Heihe River increased, and the remaining watersheds were lower than the average of many years; compared with 2009, Huaihe River, Songhua River and Heihe River Little change, other streams
