摘要
剑阁县古柏资源丰富,为世界上保存最完整、规模最大的古柏林,是优质的种质资源,对剑阁县古柏资源的特征研究,可以为其保护提供前期数据。本研究通过对剑阁县古柏资源的调查,从数量、结构、生长状况和影响因素等方面,分析其基本特征,结果表明:(1)剑阁县驿道古柏现有7 826株,但空间分布不均匀,主要分布在龙源镇和禾丰乡;(2)古柏树龄结构呈单峰曲线的分布规律,且峰值为700 a～899 a;(3)古柏生长状况与树龄无显著相关性,与冠幅、保护措施呈极显著正相关,与影响因素呈极显著负相关,以土壤因素和人为因素对其影响最大。
Ancient cypress trees in Jiange County were the world’s most preserved and largest group and high-quality germplasm resource with large quantity.The study of the characteristics including quantity,structure,growth status and influencing factors of ancient cypresses can provide preliminary data for their protection in Jiange County.The results showed that(1) There were 7826 ancient cypress trees in Jiange County,with uneven spatial distribution as Longyuan and Hefeng Town dominant.(2) The age of the ancient cypress tree had a single-peak curve distribution with a peak value of 700~899 a;(3) There was no significant correlation between the growth status with their age,but was significantly and positively correlated with the crown width and protection measures,was significantly negatively correlated with influencing factors,with soil and human factors preponderance.
