Abstract:
Objective To explore the key environmental factors influencing the distribution and spatially stratified heterogeneity of the suitable habitats of Ranunculus ternatus Thunb.;To predict its potential suitable habitats within China;To provide theoretical guidance for the conservation of its wild resources,artificial introduction and cultivation,and production planning.Methods Based on the MaxEnt model,a distribution prediction model was established using 148 selected species distribution information and 28 environmental factor data.The ENMeval package in R language was used to optimize the model parameters.Quantitative analysis(q-value ranking)of environmental factors affecting spatial differentiation in potential suitable areas using geographic detector factor detection and interaction detection.Results After optimization,the accuracy of model was improved and the degree of overfitting was reduced.The average value of the area under the curve(AUC)was 0.940.The contribution rate of environmental factors and the jackknife test showed that the key environmental factors influencing the distribution of Ranunculus ternatus Thunb.mainly included the precipitation in March,the precipitation in November,elevation,the solar radiation intensity in October,the solar radiation intensity in December,and the average temperature in January.The results of raster calculation showed that the area of highly suitable habitats of Ranunculus ternatus Thunb.was approximately 4.105×104 km2,the area of moderately suitable habitats was approximately 4.243×105 km2,and the area of lowly suitable habitats was approximately 6.385×105 km2,accounting for about 3.8%,38.4%and 57.8%of the total area of suitable habitats,respectively.Conclusion This study can provide a basis for the conservation and sustainabele utilization of the wild resources of Ranunculus ternatus Thunb.
