摘要：甘肃省地处青藏高原、内蒙古高原、黄土高原与黄河流域、长江流域、内陆河流域的交汇处,其复杂多样的生态环境与气候条件造就了丰富多样的植被区系,形成了该地区药用植物资源种类空间分布的不平衡性,因此,研究甘肃省各县(区)珍稀濒危药用植物资源种类空间分布特征,对于合理制定甘肃省珍稀濒危药用植物资源保护政策、促进药用植物产业发展具有重要的意义。该研究以甘肃省第四次中药资源普查成果为基础,运用探索性空间数据分析(ESDA)、趋势面分析、空间聚类与异常值分析等地统计学方法对甘肃省87个县(区)珍稀濒危药用植物资源种类丰富度空间分异特性进行研究,并结合甘肃省植被类型数据、土壤质地分类数据、年平均气温数据、年平均降水量数据、高程数据,分析甘肃省珍稀濒危药用植物资源丰富度高值或低值聚集区生态环境特征,进一步探析甘肃省珍稀濒危药用植物资源种类及其多样性空间分布与该区域地理环境的关系,为甘肃省珍稀濒危药用植物资源的科学恢复与保护政策制定提供支撑。
Gansu province is located at the intersection of the three plateaus(Qinghai-Tibet Plateau, Inner Mongolia Plateau, and Loess Plateau) and the three river basins(Yellow River Basin, Yangtze River Basin, and inland river basin). The complex eco-environment and climate conditions here have created rich and diverse vegetation. Therefore, it is of great significance to study the spatial distribution characteristics of rare and endangered medicinal plant resources in Gansu province for formulating reasonable protection po-licies and promoting the development of medicinal plant industry. The data of rare and endangered medicinal plant resources in 87 counties of Gansu province were collected from results of the fourth general survey. The spatial distribution and the high-or low-value gathering area of rare and endangered medicinal plant resources in Gansu province were analyzed by geostatistical methods such as exploratory spatial data analysis, trend surface analysis, and Anselin Local Moran′s I. The eco-environment characteristics of the high-or low-value gathering area were analyzed with the data of vegetation type, soil texture classification, annual mean temperature, annual mean precipitation, and elevation. Furthermore, the relationships of the spatial distribution and diversity with the geographical environment of rare and endangered medicinal plants in Gansu province were analyzed to provide support for the restoration and protection policy making of these plant resources.
