摘要
青崖寨国家级自然保护区拥有丰富的森林资源及野生植物资源,是生物多样性研究的热点地区,其空间格局分析对于研究区域尺度下生物多样性的保护具有重要的价值和意义。利用2003、2016、2020年三期森林资源调查数据,结合ArcGIS10.7软件对青崖寨国家级自然保护区的地理自然条件进行分析,得到地形因子、林分调查因子、重点保护野生植物的分布空间格局以及适宜生境分布。通过将保护区适宜生境分布与重点保护野生植物丰富度空间分布进行重叠分析,确定重点保护野生植物热点保护地区。研究结果表明,青崖寨国家级自然保护区有林地占地面积大,龄组多以幼龄为主,中郁闭度(0.4~0.6)范围植物多样性高,保护区内重点保护野生植物共有31种,其中包含5种国家Ⅱ级野生保护植物。保护区内有两处热点区域,一处是位于保护区西北部,重点分布于长寿村、荒庄、梁沟、朝阳沟内。另一处是保护区中部,位于脑沟、后渠、渠沟、七步沟、木作村交界地带。空间格局分析为保护区植物资源丰富度及多样性研究提供了科学依据,也为保护区内野生植物重点保护区的建设提供了规划及参考价值。
Qingyazhai National Nature Reserve has rich forest resources and wild plant resources, which is a hotspot area of biodiversity research. The spatial pattern analysis of Qingyazhai National Nature Reserve has important value and significance for the protection of biodiversity at the regional scale. The geographical and natural conditions of Qingyazhai National Nature Reserve were analyzed by using the forest resource survey data in 2003, 2016 and 2020, and ArcGIS10.7 software, so as to obtain topographic factors, stand survey factors, spatial distribution pattern of key protected wild plants and suitable habitat distribution. Through overlapping analysis of the suitable habitat distribution and the spatial distribution of the richness of key protected wild plants, the hotspot areas of key protected wild plants were determined. The results show that Qingyazhai National Nature Reserve has a large area of forest land, mainly young age groups, and high plant diversity in the range of middle canopy density(0.4-0.6). There are 31 species of key protected wild plants in the reserve, including 5 species of national level Ⅱ wild protected plants. There are two hotspot areas in the reserve, one is located in the northwest of the reserve, which is mainly distributed in Changshou village,Huangzhuang, Lianggou and Chaoyanggou;the other is in the central part of the reserve, located at the junction of Naogou, Houqu, Qugou, Qibugou and Muzuo village. The spatial pattern analysis provides a scientific basis for the study of plant resource richness and diversity in nature reserves, and also provides planning reference for the construction of key protected areas of wild plants in nature reserves.
