黑龙江省野生花卉种质资源区域分布及引种驯化的探讨

Approach on Regional Distribution and introduction as well as Domestication of Wild Flower Resources in Heilongjiang Province

以黑龙江省区域气候的差异为基础、依据地貌特征．将黑龙江省野生花卉的分布划分为四个区：西北部山地半干旱气候区；北部及东南部山地、丘陵半湿润－半干旱气候区；西部草原、草甸半干旱气候区；东部平原、沼泽湿润－半湿润气候区。并列出各区主要野生花卉的分布、生态学特征及观赏价值。认为：种源产地、植物材料、引种季节和方式的选择、限制植物引种适应性的主要生态因子的确定、是决定引种驯化成功与否的重要因素。

Wild flower distribution area of Heilongjiang province was divided into four regions based on the territorial climatic difference of Heilongjiang province and the characters of landforms: northwestern mountainous semiarid climatic region; northern and southeastern mountainous hill semi-humid and semiarid climatic region; western grass and meadow semiarid climatic region; eastern swampy plain humid and semi-humid climatic region. The distribution, ecological characters and appreciate value of mainly representative wild nower of each region were listed. It was considered that the key points raised for successful introduction and domestication of wild flowers are proper selection of resource area, introduction season and introduction method as well as determination of mainly ecological factors of restricting plant introduction adjustability.
