石阡县林木种质资源调查及其利用研究

Inventory of forest tree germplasm resources in Shiqian County and strategies for conservation and utilization

采用踏查、线路调查和样方调查方法对石阡县林木种质资源进行调查,发现石阡有林木种子植物179科717属1 884种,其中裸子植物8科16属25种,被子植物171科701属1 859种;对野生资源进行区系分析,表明世界分布48科、热带分布73科、温带分布45科,表现出该县野生种子植物区系具有明显的热带亲缘关系特点;按照主要用途和目标价值将林木种子植物资源进行分类、研究。根据资源现状和保存利用情况,提出了进一步挖掘、利用林木种质资源的建议措施。

Random sampling, line sampling and plot sampling were used to investigate forest tree germplasm resources in Shiqian County. The inventory found 1884 species, 717 genera and 179 families of seed plants, including 25 species, 16 genera and 8 families of gymnosperms and 171 families, 701 genera and 1859 species of angiosperms. The analysis of the wild resources in the area shows that the world has 48 families, 73 families of the tropic zone and 45 families of the tem- perate zone. It indicates that the flora of wild seed plants in the county has obvious tropical affinities. According to the main purpose and target value, the tree seed plant resources were classified and studied. Based on the current situation of resources and utilization of resources, the suggestions for further mining and utilization of forest germplasm resources were put forward.
