Abstract:
Objective To predict the potential suitable areas of Cyperus rotundus L.in China;To provide a theoretical basis for the protection of wild resources of Cyperus rotundus L.and its artificial cultivation.Methods The data of 732 sample points were collected,combined with the data of 36 environmental factors,and the feature combination and regularization multiplier parameters were optimized using R 3.6.3.The MaxEnt model and geographic information system software ArcGIS 10.4.1 were used to analyze the distribution of the main environmental factors affecting the distribution of the suitability and the distribution of the suitable areas of Cyperus rotundus L.Results The main environmental factors that significantly affected the distribution of the suitability of Cyperus rotundus L.were minimum temperature of coldest month,precipitation of driest month,mean temperature of wettest quarter,mean temperature of warmest quarter,and precipitation of warmest quarter.The highly suitable areas of Cyperus rotundus L.are mainly located in Hainan,Guangdong,Guangxi,western and southern Taiwan,southern Yunnan,southern Tibet,east-central Hubei,eastern Hunan,northern Anhui,and central Jiangxi.Conclusion The results of this study can provide references for the sustainable development of wild resources,artificial cultivation optimization,planting site selection and management.
