2、蒸发量最少月份为1月、12月。全州多年平均径流量为115.5937亿m3,径流量年内分配不均，全州汛期（6・9月）径流量占全年径流量59.8%，冬季1、2月份河流冇时会出现断流现彖。延边州水资源量随季节性变化明显。根据延边地区水文特性，捉出相关可行性建议：合理开发和规划天然水资源；从工业用水、农业用水、生活用水三方而落实捉高用水效率；增强全民保护水资源意识，推广冇效节水办法，增强全州人民爱护水资源的意识等。关键词：水资源量；降水；蒸发；径流量；洪涝灾害；水质现状；泥沙含量;水资源开发利用Abstract1956-2009accordingtotheyanbianareaprecipitati
