摘要(Abstract):

该文在基于Max Ent和Arc GIS的羌活的生态适宜性分析及评价基础上,提出了生长适宜性的概念,并利用Arc GIS软件中标准分级方案的自然断点法,对羌活的潜在分布区域进行了生长适宜性等级划分,生成羌活生长适宜性区划图并统计了不同等级适宜区的面积。结果发现,羌活生长最适宜区段主要分布在四川省的阿坝州境内,约占总最适生区的60%以上;海拔、9月均温以及植被类型是影响羌活生长的主导因子;相关性分析显示,在一定范围内降水量和坡度的增加有利于药材中羌活醇积累,而不利于异欧前胡素积累。研究结果有助于阐明药用植物生长适宜性和品质适宜性的区别,为羌活的生产区划、野生抚育及规模化人工种植提供科学依据。
Growth suitability as assessment indicators for medicinal plants cultivation was proposed based on chemical quality determination and ecological factors analysis by Maxent and Arc GIS model. Notopterygium incisum,an endangered Chinese medicinal plant,was analyzed as a case,its potential distribution areas at different suitability grade and regionalization map were formulated based on growth suitability theory. The results showed that the most suitable habitats is Sichuan province,and more than 60% of the most suitable areawas located in the western Sichuan such as Aba and Ganzi prefectures for N. incisum. The results indicated that habitat altitude,average air temperature in September,and vegetation types were the dominant factors contributing to the grade of plant growth,precipitation and slope were the major factors contributing to notopterol accumulation in its underground parts,while isoimperatorin in its underground parts was negatively corelated with precipitation and slope of its habitat. However,slope as a factor influencing chemical components seemed to be a pseudo corelationship. Therefore,there were distinguishing differences between growth suitability and quality suitability for medicinal plants,which was helpful to further research and practice of cultivation regionalization,wild resource monitoring and large-scale cultivation of traditional Chinese medicine plants.
