Outline
In response to the demand for termite prevention in hydraulic engineering， this study constructed a predictive model for termite habitat suitability in Zhejiang Province by integrating the MaxEnt ecological niche model with GIS spatial analysis technology， based on termite census data from Zhejiang Province’s hydraulic engineering projects （2023-2024）. The research systematically revealed the spatial distribution patterns and environmental driving mechanisms of termite habitats in Zhejiang Province. Through a dynamic screening process of “preliminary selection-contribution analysis-collinearity test-iterative optimization”， 22 initial environmental factors were refined to 14， achieving a model AUC value exceeding 0.963. The Jackknife test identified soil pH （6.0-6.4）， annual precipitation （1280-1450 mm） and elevation （80-200 m） as the core environmental drivers most suitable for termite survival in hydraulic engineering. Spatial simulations indicated that the total area of termite-suitable habitats in Zhejiang Province is 40，300 km²， with high-suitability zones （6 400 km²） concentrated in the hilly valleys of central and southern Zhejiang， medium-suitability areas （13，700 km²） distributed in patches in central and northern Zhejiang， and low-suitability zones （20，200 km²） covering all river basins in the province with potential diffusion risks. The research not only provides a reusable technical paradigm for biological disaster risk assessment in hydraulic engineering but also offers important references for formulating precise "one-reservoir-one-policy" prevention systems， guiding the layout of monitoring stations， prioritizing prevention efforts， and developing ecological barrier technologies.
