Method for predicting proper habitat of ginkgo fruit forest based on climate and soil factors

Abstract

The invention discloses a method for predicting the suitable habitat of a ginkgo fruit forest based on climate and soil factors, and belongs to the technical field of species distribution prediction. The method comprises the steps of firstly, establishing a climate ecological niche model and a soil ecological niche model; predicting the habitat types of the ginkgo fruit forest by using the climate ecological niche model and the soil ecological niche model, and classifying the habitat types of the ginkgo fruit forest; carrying out verification test on the model and a prediction result through a seed field test; filtering the climate-suitable habitat by using the soil-suitable habitat; and predicting the change of the suitable habitat of the ginkgo fruit forest under the future climate scene. The two models are combined, the current and future under different climate change scenes can be predicted, the reliability of model output is verified through experimental data, the prediction process is more efficient, the result is more accurate, prediction of the habitat suitability classification model conforms to the knowledge of phytophysiology and economics, and the habitat suitability classification model has good application prospects. The method has important significance for guiding the production practice of the ginkgo fruit forest.

Description

technical field [0001] The invention belongs to the technical field of ginkgo cultivation and protection, and in particular relates to a method for predicting suitable habitats for ginkgo forests based on climate and soil factors. Background technique [0002] Ginkgo biloba L. is a dioecious long-lived plant with male and female reproductive organs distributed on different trees. Ginkgo biloba has high edible and medicinal value all over the world. Ginkgo is rich in vitamins and carotene, which has a certain effect on delaying aging and promoting skin metabolism. At the same time, it has a positive effect on preventing high blood pressure, heart disease, antitussive and expectorant. The world spends more than $7 billion on botanical medicines every year, and ginkgo ranks first in botanical medicines. However, due to the impact of climate change, the suitable habitat and fruit yield of this important economic fruit forest face great uncertainty. Therefore, it is necessary...

Problems solved by technology

Since climate is a key factor in soil formation, if climate and soil variables are simply included in the model, there will be a confounding effect between climate and soil variables, which will cause soil variables to affect the prediction accuracy of the model for future climate, or climate variables dominant soil effect
