Abstract: In 1985-1990, we conducted a study on comprehensive utilization of geothermal energy to agricultural production at the experimental site in Fujian Geothermal Agro-utilization Insti-tute. Within a certain range,a comprehensive utilizing project of which the heat-providing layout was designed according to the principle of systematic engineering, so as to achieve the goal of sci-entific heat supply, multiple grade utilization of geothermal water, the heat-providing area in-creased frorm 1896 m2 to 4038 m2, the net increase was 113%, In the light of macroscopic agricul-ture, the experirmental site has become a demonstrative base for the comprehensive utilization of cultivation and pisciculture. It gives a full play to the superiority of agricultural engineering tech-nique and geothermal resources and bring a significantly economical benefit,the averaged net in-come reached 230000 Yuan/hm2, and high social benefit.
