摘要：

For the difference of soil water potential in the farmland, the variable irrigation can save water as well as raise economic benefit. This system can forecast soil water content by using the forecast mathematical model of soil water content which is measured according to the different sampling site based on GIS. Irrigation or not can be decided by comparing the current soil water content with the light of drought and serious drought index of the crop. The amount of irrigation can be decided by the analysis of economic benefit according to the model of water consumption-yield, thus the variable irrigation prescription and cluster analysis map can be made based on decision support system (DSS).
