The spatial distribution of Ophiocordyceps sinensis suitability in Sanjiangyuan Region

Ophiocordyceps sinensis is one of rare fungal species parasitizing the larvae of a moth of the genus Thitarodes (Hepialus), which mainly lives in the Tibetan Plateau of China and the Himalayas. Qinghai province is one of main yield areas of Ophiocordyceps sinensis resources in China by the statistics. Herein, spatial distribution of Ophiocordyceps sinensis suitability in Sanjiangyuan region was studied based on spatial analysis of GIS. In this study, appropriate indices of eco-environment for Ophiocordyceps sinensis suitability, including landform factor, vegetation type, and soil type, were chosen according to habitat conditions. The study may provide scientific basis for comprehensive investigation, protection, rational development and utilization of Ophiocordyceps sinensis resources. Based on the aforementioned, government should further strengthen the management and protection of Ophiocordyceps sinensis resources in order to bring about the win-win benefits of the ecological and environmental protection and improving farmers and herders income.
