| 摘 要： | 黑龙江省盐生植物包括17科43属72种,典型盐碱地段的多样性、覆盖度均在pH值为8-8.5左右时达到最好。黑龙江省盐生植物温带性质十分明显,世界分布科占绝大多数(82.35%)。北温带分布型的属所占比例最高(25%),温带亚洲分布种所占比例最大(24.2%)。盐生植物中东北植物区成分(NE)占12.50%,华北植物区成分(NC)占21.25%,东北平原亚区成分(NEP)占30.00%,东蒙古草原亚区成分(EMS)占23.75%,大兴安岭植物区成分(DA)占12.50%。特有科、属、种不存在,表现出较强的旱生性但是古老种不多。黑龙江盐生植物占全国盐生植物种数的约17%,数量不多,但是分布型多样,利用价值大。

| Abstract: | There are 72 specie of halophytes in 17 families and 43 genera in Heilongjiang,China.Distribution of the halophyte families and the halophyte genera in Heilongjiang shows that the flora has a diverse geographical characteristics,with an overwhelming number in temperate regions.The overwhelming majority families are cosmopolitan(82.35%).North Temperate type of genera(25%) is the maximum,Temp.Asia type of the species is the maximum.The faunistic component(NC) is 21.25%,NEP: 30.00%,EMS: 23.75%,DA: 12.50%.There isn't particular component. |
