针对黄连种植适生地选择的迫切要求,该文在基于生态位理论模型MaxEnt和ArcGIS的黄连区划体系研究基础上,对黄连进行了生长适宜性区划的分析,并利用统计学分析的相关方法结合Arc GIS软件,对黄连的潜在分布区进行了生长适宜性等级划分,生成黄连生长适宜性区划图。结果发现,黄连生长最适宜区主要分布在重庆石柱、武隆、巫溪、湖北利川、恩施等地。海拔、9月降水量以及2月降水量等7个生态因子是影响黄连生长的主要生态因子,相关分析结果显示,在一定范围内,降水量与海拔的升高有利于黄连中总生物碱含量的积累。研究结果不仅阐释了最适合黄连生长的自然环境,也为黄连的生产区划、也是抚育及规模化人工种植提供科学依据。
Based on the research on Coptis chinensis regionalization system based on the model of MaxEnt and ArcGIS based on the niche theory model, this paper analyzed the suitability zoning of Coptis chinensis and used the method of statistical analysis combined with Arc GIS software, the potential distribution of Coptis growth suitability classification, the growth of Coptis suitable suitability zoning map. The results showed that the most suitable area for the growth of Coptis mainly distributed in Chongqing Shizhu, Wulong, Wuxi Creek, Hubei Lichuan, Enshi and other places. Seven ecological factors, such as altitude, precipitation in September and precipitation in February, were the main ecological factors affecting the growth of Coptis chinensis. Correlation analysis showed that within a certain range, the increase of precipitation and elevation was in favor of the total alkaloid content Accumulation. The results not only explain the natural environment that is most suitable for the growth of Coptis chinensis, but also provide scientific basis for the cultivation of Coptis chinensis and large-scale artificial cultivation.
