摘要
该文基于对川贝母资源生态和品质质量的研究,在GIS平台上利用最大信息熵对野生川贝母进行生长适宜性分析,并筛选出影响川贝母生长的主导因子;利用地统计学方法插值生成基于药材品质适宜性的空间分布数据,在此基础上与川贝母植株生长适宜性空间分布数据进行模糊叠加,形成基于药材品质适宜性和植株生长适宜性空间相关联的川贝母生产适宜性区划;结合土地利用等环境因素综合分析,对川贝母生产适宜区进行功能划分,得到具有实际生产指导意义和可操作性的川贝母功能型生产区划。该文采用的中药材生长适宜性、品质适宜性和生产适宜性的评价体系及构建方法,可克服现有中药材生产区划中由于缺乏生态因子与品质因子的空间相关分析而导致的将生态适宜性与生产区划等同的误区,为川贝母的资源保护、野生抚育和产业化种植规划,提供理论支持与解决方法。
The major contributing factors for growth of endangered medicinal plants of Fritillariae Cirrhosae Bulbus were screened on the GIS platform by using the MaxEnt model, and spatial distribution data of the medicine quality suitability were generated by geosta- tistics interpolation based on reported measured data of ecology and quality suitability assessment. On this basis, a functional produc- tion cultivation regionalization with high feasibility and operability were formatted for protection, wild monitoring, and cultivation of this plant by fuzzy superposition of spatial suitability data of ecology and quality, as well as integrated with land use and cover data. There- fore, a novel assessment and regionalization method were presented for ecology, growth and quality suitability of the Chinese traditional medicinal plants. This method is expected to overcome shortage of traditional regionalization methods difficult to distinguish the contri- bution of ecological faetors and quality factors, which provide an innovative theory and methodology for regionalization, and is helpful topractical application of wild resource protection, monitoring, and commercialization cultivation for traditional Chinese medicinal plants.
