摘要: 解析川芎品质与环境因子的关联机制,探寻其空间分布规律,可为川芎基于品质导向的生态适宜区划和生产布局优化提供科学依据。本研究基于川芎有效成分含量、气候因子及海拔等多源数据,采用广义加性模型对“环境-品质”关系进行定量解析,并利用最大熵模型将该关系拓展至地理空间,确定了具备优质川芎适宜环境特征的潜在区域。结果表明:四川优质川芎适宜区空间分异特征明显,主要划分为3类区域,分别为高适宜区、中适宜区和低适宜区。其中,高适宜区总面积为3572.05 km2,在空间上呈片状或点状集中分布,主要位于成都平原西缘(涵盖彭州、什邡、绵竹、安州等)、平原西南缘向浅丘过渡带(如大邑至东坡一带),以及乐山市的夹江-峨眉山等零星区域;中适宜区总面积为8850.16 km2,除在成都平原西缘延续外,亦广泛分布于平原南延边缘以及荣县-威远、叙州-翠屏-屏山等局部地区;低适宜区总面积为38921.21 km2,分布广泛,不仅包括成都平原部分区域,还延伸至南部及西南部丘陵地带。川芎种植应实施分区规划,以高适宜区为重点,优先布局发展;对于中适宜区和低适宜区,则应控制种植规模,并加强环境监测和生产管理。

Abstract: Understanding the correlation mechanism between the quality of Ligusticum chuanxiong and environmental factors and its spatial distribution pattern can provide a scientific basis for the ecological zoning and production layout optimization of L. chuanxiong. Based on multi-source data including effective components of L. chuanxiong, climatic factors and altitude, we used the generalized additive model to quantitatively analyze the relationship between the quality and environmental factors. We used the maximum entropy model to extend this relationship to the geographical space, and determined the potential distribution areas for high-quality L. chuanxiong with suitable environmental characteristics. The results showed that the spatial characteristics of high-quality L. chuanxiong areas differed obviously in Sichuan, mainly manifested as the highly-suitable area, the moderately-suitable area, and the poorly-suitable area. Among them, the highly-suitable area, which was concentrated in patches or spots, was approximately 3572.05 km2, mainly distributed in the western edge of the Chengdu Plain (including Pengzhou, Shifang, Mianzhu, and Anzhou), the transition zone from the southwestern edge of the plain to the shallow hills (e.g., the area from Dayi to Dongpo), and scattered areas in Leshan. The moderately-suitable area was approximately 8850.16 km2, which included not only the extending regions along the western edge of the Chengdu Plain, but also the southern extension of the plain and local areas such as Rong County-Weiyuan, Xuyuan-Cuiping-Pingshan. The poorly-suitable area was 38921.21 km2, including parts of the Chengdu Plain extending to the southern and southwestern hilly areas of Sichuan. The cultivation of L. chuanxiong should be implemented with zonal planning, prioritizing the layout and development of highly-suitable areas as the core focus. For the moderately-suitable and poorly-suitable areas, the cultivation scale should be controlled, and environmental monitoring and production management should be strengthened.
