当地收获的野生食用植物（WEP）为土著人民提供食物和现金收入，对于确保全球粮食安全具有重要意义。有些还在维持传统农业生态系统的生产力和稳定性方面发挥着重要作用。中国西南部云南省香格里拉地区被视为生物多样性热点地区。生活在那里的人们积累了有关植物的传统知识。然而，随着经济的发展，WEP受到威胁，相关的传统知识也面临流失的危险。因此，在该地区开展了民族植物学调查，对当地藏族传统食用的野生食用植物进行了调查和记录。选择了29个村庄进行实地调查。通过直接观察、半结构化访谈、个人讨论、关键知情者访谈、焦点小组讨论、问卷调查和参与式农村评估（PRA）来收集信息。记录了62科116属168种野生食用植物的信息并采集了标本。大多数物种是可食用的绿色蔬菜（80 种）或水果（78 种）。这些WEP是当地人，特别是生活在偏远农村地区的人们获取矿物质元素和维生素的来源。超过一半的物种 (70%) 除食用价值外还有多种用途。有些是作物野生近缘种，可用于作物改良。其中一些还具有进一步商业开发的潜在价值。然而，WEP 的利用和相关知识正在迅速被侵蚀，特别是在交通便利、旅游业蓬勃发展的地区。香格里拉地区野生食用植物种类丰富多样。它们为当地人提供食物和营养，也可以成为现金收入的来源。然而，WEP 及其相关本土知识都面临着各种威胁。因此，该地区这些植物的保护和可持续利用至关重要。这些物种的记录可以为保护、可能的进一步开发提供基本信息，并将保存当地的传统知识。
Locally harvested wild edible plants (WEPs) provide food as well as cash income for indigenous people and are of great importance in ensuring global food security. Some also play a significant role in maintaining the productivity and stability of traditional agro-ecosystems. Shangri-la region of Yunnan Province, SW China, is regarded as a biodiversity hotspot. People living there have accumulated traditional knowledge about plants. However, with economic development, WEPs are threatened and the associated traditional knowledge is in danger of being lost. Therefore, ethnobotanical surveys were conducted throughout this area to investigate and document the wild edible plants traditionally used by local Tibetan people. Twenty-nine villages were selected to carry out the field investigations. Information was collected using direct observation, semi-structured interviews, individual discussions, key informant interviews, focus group discussions, questionnaires and participatory rural appraisal (PRA). Information about 168 wild edible plant species in 116 genera of 62 families was recorded and specimens were collected. Most species were edible greens (80 species) or fruits (78). These WEPs are sources for local people, especially those living in remote rural areas, to obtain mineral elements and vitamins. More than half of the species (70%) have multiple use(s) besides food value. Some are crop wild relatives that could be used for crop improvement. Several also have potential values for further commercial exploitation. However, the utilization of WEPs and related knowledge are eroding rapidly, especially in the areas with convenient transportation and booming tourism. Wild food plants species are abundant and diverse in Shangri-la region. They provide food and nutrients to local people and could also be a source of cash income. However, both WEPs and their associated indigenous knowledge are facing various threats. Thus, conservation and sustainable utilization of these plants in this area are of the utmost importance. Documentation of these species may provide basic information for conservation, possibly further exploitation, and will preserve local traditional knowledge.
