In order to figure out the status and distribution of wild cultivated resources traditional Chinese medicine Daphnes Cortex, its suitable habitat endangering factors were analyzed provide basis for rational use, protection cultivation.Our research group tooka survey in Shanxi, Gansu, Sichuan Qinghai provinces, which include 23 counties. Investigation sampling investigation combined with interview carried out. The total reserve was estimated through route-quadrat method combination vegetation soil-type map area method. results indicated that there no obvious change between present ranges Cortex historical records, but density population has undergone major changes. reserves declined seriously, even on verge exhaustion some regions. According results, current four provinces more than 600 tons. Simultaneously, we only found resource a mountain at an altitude about 2 800 m Kang county Gansu province, cropping scope 33 000 m². can't medicinal products present, because their growing period is too short have curative effect. Destructive excavation longer growth cycle result sharp decline reserves, point extinction. Artificial cultivation product will become main source future. Therefore, must protect habitat, formulate harvesting policy, strengthen supervision government departments, collect establish germplasm nursery seed bank. On basis, carry studies into seed-selecting breeding as well rapid propagation technology once.
