A Percolation Model for Pest Perturbation in Diverse Habitat and Network Computing Soft ware
Habitat diversity is the important mechanism for retarding the percolation of pest perturbation and the emergence of destructive pest populations.Based on the basic features of pest percolation in the field,a stochastic model for the percolation ofpest perturbation and its network computing software,PercoModel (c) ,was developed.PercoModel (c) is made of8Java classes and1HTML file.PercoModel (c) can be run on various operational systems,platforms and web browsers,and can read various ODBC linked databases such as MS Access,Excel,FoxPro,dBASE et al.The software can be used to:(1)analyse the effects exerted by habitat diversity,e.g.,different habitat arrangement patterns and vegetable arrangements,on percolation of pest perturbation;(2)determine the effects exerted by habitat diversity on plant epidemiologic diseases and insect diseases;(3)approach the effects exerted by habitat diversity on fire percolation;(4)determine the yield loss caused by pest and the spatial distribution of the loss,and analyse the optimal habitat arrangement patterns for reduce the loss,et al.
