[摘要]为解决药材生长最适宜生长区域与高品质区域空间分离的问题,建立具有针对性生产指导的区划,该文以羌活药材为例提出综合考虑药材生长适宜性和品质适宜性的中药材功能型生产区划方法。基于前期羌活生长适宜性和品质适宜性区划的研究结果,将羌活生长适宜性空间矢量数据与药材品质适宜性空间矢量数据进行空间加权总和处理,获得羌活生产适宜性空间矢量数据,发现优质高产区域主要分布在道地产区四川省境内;利用研究区域的土地利用现状遥感监测数据进一步对羌活生产适宜区进行功能划分,发现适宜羌活规模化种植和野生林地抚育区主要分布在四川阿坝州和甘孜州境内,与实地调研结果一致。该研究结果将为羌活的道地性研究、野生资源保护、产业化种植和野生林地抚育提供科学的理论依据与技术支持。

[Abstract]Based on the research results of suitability evaluation of growth and production quality, a functional production cultivation regionalization with high feasibility and operability to solve the problem of the separation of high quality and high yield were formatted for protection, wild monitoring, and cultivation of this plant by weighted sum of spatial suitability data of ecology and quality, as well as integrated with land use and cover data The results of the study revealed that good quality and high yield area were mainly distributed in the original production areas in Sichuan province and where could carry out monitoring and commercialization cultivation This method is expected to overcome shortage of traditional regionalization methods difficult to distinguish the contribution of ecological factors and quality factors, which provide an innovative theory and methodology for regionalization, and is helpful to practical application of wild resource protection, nature research, monitoring, and commercialization cultivation for Chinese material medica

中药区划主要是研究中药材品質及产量空间属性及其地域系统的空间分异规律,最终综合社会、经济及人为因素进行区域划分,其研究成果可为中药材的生产提供基础数据和技术支撑[1]。由于区域之间中药材所在地的自然生态和人为因素等“立地条件”不同,中药材生长及品质适宜性的空间分异规律或许不同[2]。即植物积累次生代谢产物所需的适宜生境(药材品质适宜性)与其生长发育的适宜生境(植物生长适宜性)可能并不一致,甚至相反,即药材的高产中心有可能与高质中心分离或者偏离[3]。……
