Abstract In order to comprehend the present status of Allium ovalifolium Hand.-Mzt. germplasm
resources in Wufeng Dahuaping, a systematic investigation on the main habitats of Allium ovalifolium
Hand.-Mzt.was conducted based on ethnobotanist theory,combined with field study and representative
plot survey.The results showed that Allium ovalifolium Hand.-Mzt.in Dahuaping distributed mainly
under the deciduous broad leaf mixed forest where the altitude was 1 800-2 100 m.The ground coverage
by plant was 35%-80%.The total area of Allium ovalifolium Hand.-Mzt. in this area was 11.3 hm2.
The maximum density was 228 plants per square meter.The population number decreased very quickly,
which indicated that Allium ovalifolium Hand.-Mzt.was facing extinct danger and studies on protecting
measures must be strengthened immediately.
