濒危野生新疆阿魏低空遥感资源调查

Resource Investigation for Endangered Wild Ferula sinkiangensis Based on Low Altitude Remote Sensing

目的:作为新疆特有的濒危药用植物,新疆阿魏的资源分布区域和数量对其保护和资源的可持续利用具有重要意义。方法:本文采用低空遥感和地面样方调查,对新疆阿魏地理空间分布和数量进行调查研究。结果:低空遥感调查结果首次清晰确定新疆阿魏的地理分布区域,将已知的"阿魏滩"扩大到附近5个山头,覆盖范围约0.88 km2,建议扩大围栏保护面积。同时,低空遥感影像分析出的分布区域内黄叶新疆阿魏(直径在0.3 m以上)数目大约为3 191株。而地面样方调查得到直径在0.3 m以上的黄叶阿魏数目为2 752株,两者之间误差为14%。并确定了新疆阿魏低空遥感监测的时相和监测范围。结论:低空遥感技术具有快速获取新疆阿魏分布现状的优势,可有效评价新疆阿魏资源动态变化。

As the specific endangered medicinal plant in Xinjiang, resources and distribution of Ferula sinkiangen- sis are important for biodiversity conservation and sustainable development of Chinese medicine resources. The spa- tial distribution and resources of F. sinkiangensis were researched based on low altitude remote sensing and sample investigation. The results showed that the optimum working time for F. sinkiangensis monitoring by low altitude remote sensing was the nearby 5 hills, which covered about 0.88 km^2. It was suggested that the fence area should be expanded for protection. According to the results of low altitude remote sensing, the amount of F. sinkiangensis in yellow （diameter exceeding 0.3 m） was about 3 191. However, the sample investigation on amount of F. sinkiangensis in yellow （diameter exceeding 0.3 m） was about 2 752. The error between them was 14%. The monitoring time and range for F. sinkiangensis by low altitude remote sensing were also ensured. It was concluded that low altitude re- mote sensing had the advantage of quickly receiving distribution situation of F. sinkiangensis, which can effectively evaluate dynamic changes of F. sinkiangensis in Xinjiang.
