Examples
- The morphologic characters and the ecological plasticity of three dryopteris crassirhizoma populations were studied
摘要对吉林省东部山区的3个粗茎鳞毛蕨种群进行了形态特征及其生态可塑性的研究。 - The results showed that plant height , crown breadth , leaf number , leaf breadth and sporophyll number of dryopteris crassirhizoma populations were influenced by forest crown density and light condition
结果表明:林分郁闭度和光照条件显著影响粗茎鳞毛蕨种群的株高、冠幅、叶片数量、叶片宽度、孢子叶数等形态指标。 - Though dryopteris crassirhizoma usually vegetated under forest and had definite overcast endurance , the excessively overcast environment went against the growth and reproduction of dryopteris crassirhizoma population
尽管粗茎鳞毛蕨常生长在林下,有一定的耐阴性,但是过阴环境不利于粗茎鳞毛蕨种群的生长发育和繁殖更新。 - The competition among those species like s . tsinyunensis , dryopteris erythrosora and veronicastrum stenostachyum etc . , is intense in the communities , which may be one of the reasons why s . tsinyunensis is going to be endangered and with a very restricted distribution . the distribution patterns of the seven populations of s . tsinyunensis are clumped among the eight populations we studied , except population v of random distribution . the spatial pattern of 6 populations of s . tsinyunensis have high consistency with the negative binominal distribution , while another 2 populations , i . e . , i and iii are poisson distributions
6 )缙云黄芩各种群空间分布格局基本呈聚集分布,其中7个种群的分布格局类型是聚集分布,其聚集强度较高,另有一个种群为随机分布;其种群的离散分布拟合结果也严格符合一定的数学模式,其中负二项分布、 poisson分布分别是该物种种群空间分布的理论分布模式,其中6个种群拟合出的结果是负二项分布,种群i和种群m拟合出的结果是poisson分布。
