Water conservation service is an important ecosystem service, which directly affects the overall level of regional water resources and has an important impact on regional ecosystem, agriculture, industry, human consumption, hydropower, fishery and recreational activities. It is of great significance to maintain ecosystem stability and improve human well-being. Aiming at the production of water conservation products, based on the principle of water balance, coupled with the data of rainfall, evapotranspiration, solar radiation, temperature and vegetation type, the modeling of water conservation of ecosystem in national barrier area is studied. The water conservation service is calculated by the invest model based on the principle of water balance. The invest model has the advantages of less input data, large amount of export data and quantitative analysis of abstract ecosystem service functions. It is an important means of water conservation service evaluation at present. This method considers that the water conservation service is precipitation minus evapotranspiration, and the calculated indexes include annual precipitation and annual evapotranspiration. The precipitation data is based on the meteorological station data, the daily meteorological data is accumulated to the annual scale, and then interpolated to the space by ArcGIS spatial interpolation method; The calculation of evapotranspiration is realized by Zhang model. Taking multi-source data as the input variable of the invest model, the estimation of water conservation services in the Qinghai Tibet Plateau with a resolution of 1km from 2000 to 2020 is realized based on the parametric model.

File naming and required software

Water conservation data is stored in grid data, and the name of the file is "wyyyyy. TIF", where yyyy represents the date. For example, wy2000. TIF represents NPP water conservation in 2000;
Data reading method: after decompression, open it in ArcGIS software.
