摘要
目的:掌握富裕县野生药用植物资源及区域生境质量的现状,并从生境质量角度解释野生药用植物资源的变化特征。方法:采用代表区域-样方调查法对该区域野生药用植物资源进行调查,分析其资源多样性,并运用InVEST模型评估富裕县1980-2020年生境质量的时空变化情况。结果:富裕县野生药用植物种类总计57科161属253种,以单种科和小型科为主,草本类植物比例最大;野生重点药用植物的出现频率和蕴藏量低;2个代表区域草本药用植物的多样性水平较为相似。与前次普查结果比较分析可知,物种丰富度增加,但重点药材的蕴藏量锐减。1980-2020年间,富裕县生境质量退化严重,指数下降了18.20%。生境质量较高等级区的面积锐减,仅零星分布于草地和沼泽地区,原生境质量较高等级地区的土地利用类型转为耕地和盐碱地;生境质量较低等级区的面积激增,以原分布区为中心呈现出向外扩散的趋势。结论:富裕县野生药用植物多样性较为丰富,但适宜野生药用植物生长的环境日益恶化。因此,建议制定有效的保护方法与措施,促进野生药用植物资源可持续性发展。
Objective: To investigate current situation of wild medicinal plants resources and regional habitat quality in Fuyu county, explain the variation characteristics of wild medicinal plants resources from the perspective of habitat quality.Methods: The investigation method of representative area-sample quadrat was used to survey the wild medicinal plants resources in this area, the diversity of resources was analyzed.InVEST model was used to evaluated the temporal and spatial changes of habitat quality from 1980 to 2020.Results: There were 253 species of 161 genera and 57 families in Fuyu county, mainly monotypic family and small family, herbaceous plants had the largest proportion.The reserve and occurrence frequency of wild key medicinal plants were low.The diversity levels of herbal medicinal plants in the two regions were similar.Compared with the previous survey results, species richness increased, but the reserve of key medicinal materials decreased sharply.From 1980 to 2020,the habitat quality in Fuyu county was seriously degraded, the index decreased by 18.20%.The areas with higher quality of habitat were sharply reduced and only scattered in grassland and marsh areas, the land use types of the original areas with higher quality of habitat were changed to arable land and saline-alkali land.The area of low grade habitat quality increased rapidly, and original distribution area as the center showed a trend of outward diffusion.Conclusion: The diversity of wild medicinal plants in Fuyu county is abundant, but the environment suitable for the growth of wild medicinal plants is deteriorating.Therefore, it is suggested to formulate effective protection methods and measures to promote the sustainable development of wild medicinal plants resources.
