宁夏灵武白芨滩国家级自然保护区沙冬青资源储量调查及保护利用

Investigation and Protection and Utilization of Ammopiptanthus mongolicus(Maxim.ex Kom.)Cheng f.Reserves in Baijitan National Nature Reserve of Lingwu of Ningxia

采用数量调查监测新方法——样圆调查法,结合无人机航拍调查,较准确地估算宁夏灵武白芨滩国家级自然保护区珍稀濒危物种——野生沙冬青的资源储量。结果表明:野生沙冬青资源储量约为9.35万丛;并探讨了野生沙冬青自然更新能力差的原因,提出相应的保护利用措施,以期为林业调查监测人员提供参考。

Combining UAV photography technology,a new investigation and monitoring method-----circular sampling investigation method was used to estimate reserves of Ammopiptanthus mongolicus(Maxim.ex Kom.)Cheng f.,a kind of rare and endangered species in Baijitan National Nature Reserve of Lingwu of Ningxia.The result showed that the reserves of Ammopiptanthus mongolicus(Maxim.ex Kom.)Cheng f.reached 93.5 thousand clumps.Meanwhile,causes of poor natural regeneration ability of Ammopiptanthus mongolicus(Maxim.ex Kom.)Cheng f.were analyzed;and the related countermeasures were proposed,aiming at providing references for professional and technical personnel.
