第四次全国中药资源普查中植物新物种的空间分布特征及影响因素分析
Spatial distribution characteristics and influencing factors of new plant species based on the fourth national survey of Chinese materia medica resources
摘要
Abstract
To analyze the spatial distribution characteristics and driving mechanisms of new plant species in the fourth national survey of Chinese materia medica resources,the data obtained from the survey were analyzed using a geographic detector.The results showed that 207 new plant species were classified into 59 families and 127 genera,distributed in 19 provinces,71 cities,and 136 counties.In general,there was significant spatial heterogeneity,exhibiting spatial positive correlation and aggregation characteristics.Additionally,the overall distribution was in an"increasing and decreasing"trend from west to east,while new plant species richness was high in the central and southern regions,which was similar to the trends of biodiversity and Chinese materia medica resource richness in China.Further analysis by the geographic detector revealed that the largest influencing factor of single factor detection q was watershed type(0.45).After the dual-factor interactive detection,the explanatory power of spatial heterogeneity was significantly enhanced after the altitude factor interacted with other factors.This study reveals the spatial distribution characteristics of new plant species,and the mechanisms between complex environmental factors and taxonomic human capital in the fourth national survey of Chinese materia medica resources,providing a scientific basis for the development and utilization of Chinese materia medica resources and biodiversity conservation strategies.关键词
