The purpose of the research is to study the history and characteritics of cherry blossom,serve for "travel of ornamental flower" and "economy of orna?mental flower"

对武汉清凉寨景区野生樱花的群落结构及物种多样性进行了调查研究。在调查区域内发现了5种野生樱花,即崖樱桃(Prunus scopulorum Koehne)、刺毛樱桃(Prunus setulosa Batal)、短萼樱(Prunus cantabrigiensis Stapf)、单齿樱桃(Prunus conradinae Koehne)、西南樱桃(Prunus pilosiuscula Koehne)。景区内野生樱花分布广泛,主要分布区海拔为570~720 m。野生樱花所处群落类型多样,群落中植被资源丰富,物种多样性高;樱花种群在所处群落中重要值较高,且具有较宽的生态位;景区内野生樱花的年龄结构显示野生樱花呈增长型演替。

The plant community structure and species diversity around wild oriental cherry in Qingliangzhai scenic region of Wuhan city were investigated. In the investigated region,five wild oriental cherry species were found,namely Prunus scopulorum Koehne,Prunus setulosa Batal,Prunus cantabrigiensis Stapf,Prunus conradinae Koehne,and Prunus pilosiuscula Koehne. In this scenic region,wild oriental cherry plants were distributed widely,and mainly in the district with the elevation of 570~720 m. The type of plant community around wild oriental cherry was various,the vegetation resources in these communities were rich,and the species diversity was high. Wild oriental cherry population in surrounding community had higher important value and wider ecologi-cal niche. The age structure of wild oriental cherry population in Qingliangzhai scenic region showed it was in an increasing-type succession.

在广泛调查山樱花地理分布信息的基础上，利用目前常用气候指标，对山樱花地理分布及其与气候的关系进行了研究。结果表明：山樱花分布于东亚温带（102～141° E，23～40° N），海拔50～1800 m之间。气候环境指标的研究结果显示山樱花热量分布范围整体偏低，在中国的热量分布范围要远大于朝鲜半岛-日本的分布。根据主成分分析可知，影响山樱花分布的重要环境因子为年均温、纬度、极端低温、1月均温和海拔。热量因子中年均温在7?91～17?92℃，极端低温不低于-17?3℃，1月均温-6?31～8?48℃的区域范围内适于山樱花的生长。基于此，提出山樱花分布的7大区域，包括中国西南地区、华中地区、华南北部及华东南部地区、华北及东北南部地区和台湾地区，以及朝鲜半岛地区、日本地区，并得到主成分分析图的支持。

Based on the geographical distribution information of Cerasus serrulata, the interaction of vegetations and cli-mates have been studied by 13 widely used indices. The results showed, the distribution region of C. serrulata was tem-perate East Asian, it was 23-40°N, 102-141°E, and the elevation range was 50-1 800 meters. The climatic indices showed that the tree have a low heat range,and the range of heat distribution in China is much wider than in the Korean Peninsula-Japan distribution. The result of principal component analysis revealed that annual mean temperature,latitude, coldest temperature,average temperature of January and elevation ranges was the most important environment factors to influence the distribution. The suitable heat factors for the growth of C. serrulata was the range of annual mean tempera-ture between 7?91-17?92 ℃, coldest temperature not less than 17?3 ℃, average temperature of January between 6?31 ℃ and 8?48℃.

在福州国家森林公园对福建山樱花6个品系（ FZ1、FZ5、FZ22、FZ41、FZ67、FZ159）的开花物候特性进行观测，结果表明：福建山樱花的花色主要有深红、粉红和白色3种，开花特性则主要有先花后叶、花叶齐放2种类型；不同福建山樱花品系的开花物候不同，FZ1、FZ5、FZ22、FZ41、FZ67这5个品系在开花持续时间、盛花持续时间方面差异不大，分别为12～14 d、7～9 d，FZ159的开花持续时间为20 d，盛花持续时间为15 d；同一品系的福建山樱花，不同树冠层和不同方位的花枝开花物候不一致，总体表现为在同一树冠层面，西方位的枝条开花最早，北方位的次之，南方位的再次，东方位的枝条开花最迟；在同一方位，下层花枝开花较上层早1～3d；同一品系的福建山樱花花枝开花数量差异不显著，而不同品系的福建山樱花花枝开花数量差异极显著，其中以FZ1花量最大。可为福建山樱花的花期预报、花期调控、园林绿化配置造景提供参考。

The test of Cerasus campanulata flowering phenology had been carried out on 6 strains(FZ1,FZ5,FZ22,FZ41,FZ67, FZ159) in Fuzhou National Forest Park.It turns out that this species has 3 flower colour type trains,crimson,pink and white.They bloom before leaf or in the middle of leaf.The different strain has different flowering phenology character.The length of flower season and peak flowering endurance are both quite similar among the 5 strains of FZ1,FZ5,FZ22,FZ41 and FZ67.The length of flower season is 12~14 d,and the peak flowering endurance is 7~9 d.The FZ159 strain flowering last 20 d,with a peak flowering endur-ance of 15 d.All the strains share the same law that they first flower on westward twigs ,then northward ones ,then the southward ,and then comes the eastward.On each specific orientation ,the substratum twigs bloom 1~3 d early then the superstratum ones.There is no significant difference on flower quantity among the same strain Cerasus campanulata individuals,but vrey signi
