摘要
利用1980—2021年甘南州洮河流域自动站(碌曲、卓尼、临潭)资料,运用气候分析、种植区划和模糊数学方法对洮河流域绿色道地药材当归气候生态种植区划和品质区划进行了研究。结果表明:1980—2021年,除了碌曲、临潭年日照时数呈下降趋势外,3个站点的年平均气温、年降水量、年相对湿度、≥0℃年积温均呈上升趋势;根据当归种植适宜性,将甘南州洮河流域划分为最适宜种植区、适宜种植区、次适宜种植区、可种植区、不宜种植区;根据当归品质等级,将其分为品质好区、品质较好区、品质一般区、品质较差区、品质差区;同时运用模糊数学方法,结合Fuzzy模型进行计算后,得出了气候生态适宜性与生产布局存在一定吻合的结论,为当归生产基地建设提供了科学的参考依据。
Based on the data of automatic stations(Luqu,Zhuoni and Lintan)of Taohe River basin in Gannan Prefecture from 1980 to 2021,climate analysis,planting regionalization and fuzzy mathematics were used to study the climate ecological planting regionalization and quality regionalization of Angelica sinensis(Oliv.)Diels,a green genuine regional drug in Taohe River basin.The results showed that from 1980 to 2021,except for the decreasing trend of annual sunshine hours in Luqu and Lintan,the annual average temperature,annual precipitation,annual relative humidity and annual accumulated temperature of≥0℃at the three automatic stations all showed an upward trend.According to the suitability of Angelica sinensis cultivation,the Taohe River basin in Gannan Prefecture was divided into the most suitable planting area,suitable planting area,sub-suitable planting area,cultivable area and unsuitable planting area.According to the quality grade of Angelica sinensis,it was divided into the best quality area,better quality area,average quality area,poorer quality area and the poorest quality area.At the same time,using fuzzy mathematics and Fuzzy model to calculate,this paper concluded that there was a certain consistency between climate ecological suitability and production layout,which provided scientific references for the construction of Angelica sinensis production base.
