摘　　要：为厘清西藏全区砂生槐植物资源的分布范围、面积、资源储量及生态状况,通过查阅文献、实地勘察、访谈了解和生物学鉴定等方法,在西藏全区范围内开展砂生槐资源专项调查。结果表明:西藏全域内有砂生槐面积206 560 hm^(2),涉及5个地市、32个县(区)、160个乡镇;砂生槐群落大致可分成4类:砂生槐群落、砂生槐+藏沙蒿群落、藏沙蒿+砂生槐群落、砂生槐+固沙草群落;砂生槐资源生态功能显著,但在砂生槐专项培育、科学合理利用、防沙治沙和高原特色产业发展中并未取得显著成效,应在加大政策保障力度、设置合理的保护对策和增加相关产品开发利用试点工作等方面增加投入力度,以推进砂生槐生态产业持续发展。In order to clarify the distribution range, area, resource reserves and ecological condition of the Sophora moorcroftiana resources in Tibet, a special survey on the resources of Sophora moorcroftiana has been carried out in Tibet, through literature review, field survey, interview and biological identification. The results show: the area of Sophora moorcroftiana is 206 560 hm^(2), involving 5 prefectures(cities), 32 counties(districts), and 160 townships;the Sophora moorcroftiana communities can be roughly divided into 4 categories: Sophora moorcroftiana community, Sand-producing Sophora moorcroftiana +Artemisia wellbyi community, Sand-producing Artemisia wellbyi+Sand-producing Sophora moorcroftiana community, Sand-producing Sophora moorcroftiana+Orinus thoroldiis community;the ecological function of Sophora moorcroftiana resources is remarkable, but no obvious results have been achieved in the special cultivation of Sophora moorcroftiana, scientific and rational utilization, sand control and plateau characteristic industry development;in order to promote the sustainable development of the ecological industry of Sophora moorcroftiana, more investment should be made in the aspects of strengthening the policy guarantee, setting up reasonable protection countermeasures and increasing the pilot work of the development and utilization of related products.
