Abstract:

Aims Our objective is to provide a scientific basis for optimization of tobacco planting.
Methods First, we analyzed the ecological factors that impact tobacco’s cultivation and quality. Second, we applied ARCGIS spatial analysis to obtain elevation and slope factors. Third, we obtained the vegetation index, surface temperature, soil moisture and solar radiation factor based on conventional remote sensing models. Fourth, we used Kriging interpolation to encrypt the geochemical data. Then we applied AHP analysis to establish a comprehensive evaluation system for tobacco cultivation.
Important findings Several environmental factors have a major impact on tobacco distribution, growth and quality. These include light, temperature, soil type, rainfall, soil moisture, altitude, slope and heavy metal pollution. These factors are also essential for optimizing allocation of tobacco cultivation. The spatial distribution of tobacco cultivation in the experimental area needs to be optimized.
