Abstract: For real-time obtaining soil salinity，groundwater table，groundwater salinity，and climate information in study area，comprehensive management system for saline-alkali soil was designed.System could offer data support for saline-alkali improvement effect and effective management in study area.This system monitored study area as a whole by using web camera，soil monitoring sensors，pipeline water monitoring sensors，meteorological station，et al.All the information in the study area was transmitted reliably by using ZigBee wireless network and internet technology.In monitoring terminal，web technology and browser/server network structure were used to apply the integration of bottom control network and internet.Then remote management system was established.It could dynamic display video images and change of environmental factors in study area，thus to provide technical support for saline-alkali soil.
