结冰期最长的河流The longest river in ice period
黑龙江总长度约5 498千米(以克鲁伦 河为源头计算)，发源于蒙古肯特山南侧，在石喀勒河与额尔古纳河交汇处形成。它经过中国黑龙江省北界与俄罗斯哈巴罗夫斯克 区东南界，注人鄂霍次克海的鞑靼海峡，将西伯利亚和库页岛分开，为北亚最长的河流。 黑龙江流域水量丰富，流域年径流量 3 465亿立方米。降水季节分配不均，每年4一 10月暖季降水量占全年的90% — 93% ;11月份进入冬半年枯水期，冬半年降水均以雪的形式降落。黑龙江是我国结冰期最长的河流。它在每年10月下旬开始结冰，上游在11月初封冻，在5月初解冻;下游在11月下半月封冻，在来年4月底解冻。如此一来，其冰期就长达6个月。 黑龙江流域内森林以及金、煤等矿产资 源丰富，产鱼类，尤以大马哈鱼和鳇鱼最为著名。Heilongjiang a total length of about 5498 kilometers (calculated in grams of RulonRiver as the source), originated from Mongolia Kent mountain on the south side,in the stone Ka Le River and Eergu'Na River Interchange form. It passes throughChina is bounded on the north by Heilongjiang province and SoutheastKhabarovsk district industry in Russia, injection of the sea of Okhotsk Tatar Strait, separating Siberia and Sakhalin Island, to the north of the longest rivers.Heilongjiang river basin water is rich, the annual runoff of 346500000000 cubic meters. Seasonal distribution of uneven rainfall, annual 4 October warm seasonprecipitation accounted for 90% - 93%; in November to enter the winter dry season, winter half year precipitation are landing in the form of snow.Heilongjiang is China's longest river ice period. It started in late October every year ice, upstream in the early 11 frozen, thawed in the early 5; in the downstream of 11 the second half frozen, thaw in the coming year at the end of 4.Thus, the glacial period as long as 6 months. The Heilongjiang Basin forest, gold,coal and other mineral resources Yuan Fengfu, fishes, especially in salmon andsturgeon is the most famous.
