Application of land quantified model in land use system
土地定量化模型在土地利用系统的应用

After the calibration, the land quantified model (PS123) is used to analyze several factors of land use system such as the sealing date, irrigation scenario and biophysical potential production. The optimum seeding date is from the end of September to October. The irrigation amount is 180 - 240 mm and it is appropriate to irrigate 75 - 90 mm each time at the last part of the growing season. The biophysical potential yield of Quzhou region is about 11010kg/hm2 .
