Abstract:There is acomplex mutual response mechanism between land useand ecological environment inareas prone to geological disasters.Research hasshown thatland usehas significant spatial avoidanceandfunctional adjustment responses togeologicaldisasters,whichreshapelandusepaternsthroughriskconstraintsandevent impacts.Thevegetation soil systemexhibitssensitive degradationresponse to landusedisturbance,andtheecological environment has important buferingand protectivefunctions against geological disasters.Thecouplingoflanduseand ecological environmentformsa complexnonlinearresponse mechanism,which maintains thedynamic balanceofthesystem through positiveandnegative fedback mechanisms,andundergoes state transitionsatcriticalthresholds,providingscientificbasis forthesustainable development of geological hazard prone areas.
