METHOD FOR MONITORING CHANGE OF VEGETATION WATER CONSERVATION

摘要

The present invention relates to a method for monitoring a change of vegetation water conservation. The method includes: obtaining global land water storage change data, precipitation, actual evapotranspiration, soil moisture storage, snowmelt, snow water storage, surface water storage, groundwater storage, change in surface and groundwater resources, litterfall interception water storage, average natural water content, maximum water holding capacity and litterfall accumulation; preprocessing the above data, and calculating a change of vegetation canopy water storage; calculating a change of litterfall interception water storage; calculating a change of soil moisture storage; and determining a water conservation change according to the change of vegetation canopy water storage, the change of litterfall interception water storage and the soil moisture change. The method provides new technical support and reference for the evaluation of ecological effects and water conservation during ecological restoration.
