| 中文摘要: |
| 采用实地调查、查阅资料、走访等方法,对河北省古树名木资源的基本特征、生长场所和生长状况等信息进行调查。结果表明,河北省古树名木共计505 470 株,其中单株12 763 株,群状492 707
株,隶属34科69属121种,树种多样但优势种极明显。单株古树名木海拔分布与数量呈极显著相关性,随海拔升高数量逐渐减少;单株和群状古树名木在纬度分布规律上具明显的一致性,且分布于北纬40°纬度带数量最多;坡度对古树名木分布亦有较大影响,其中平坡分布数量最多。不同树
种在海拔、纬度、坡度分布上呈明显差异性,体现了不同树种对海拔、纬度、坡度的适应性强弱不同,一定程度上反映了不同树种的适生条件。 |

| By means of field investigation, consulting materials and visiting, the basic characteristics,
growth places and growth status of ancient and famous trees in Hebei Province were investigated. The results
showed that there were 505 470 ancient and famous trees in Hebei Province, including 12 763 individual
trees and 492 707 clustered trees, belonging to 121 species, 69 genera and 34 families. The tree
species were diverse but the dominant species were extremely obvious. The altitudinal distribution of individual
ancient and famous trees showed a highly significant correlation with their population size, which
gradually decreased as the elevation increases. Both individual and clustered ancient and famous trees exhibited
remarkable consistency in latitudinal distribution patterns, with the highest abundance found in
the 40°N latitude zone. Slope gradient also significantly influenced the distribution of these trees, with
the largest number distributed on gentle slopes. The distribution of different tree species showed obvious
differences in altitude, latitude and slope, reflecting the varying adaptability of different tree species to
altitude, latitude, and slope, which reflected the suitable conditions of different tree species. |
