The shallow-styled solar pond is divided into the upground pond and the underground pond. It is the complete set equipment of the conservatory-modeled solar pond. It is used to heat the working water body for breeding young aquatic products in advance and cultivating bio-baits.

The concrete-brick structure is adopted to build the upground shallow-styled solar pond. The five layers of the interior surface are waterproof. Asphalt lacquer is painted and dropless translucidus membrane is adopted. The shallow-styled solar pond is multifunctional. The pond is 1m deep, 80m long and the effective volume is 750 m3. There are 12 ponds in it. The ponds of NO.1 to NO.6 are used to demonstrate the breeding, NO.8 to NO.10 are used to cultivate bio-baits and NO.11 to NO.12 are used to heat the working water body.

The upground solar pond of shallow style is in operation for 2 periods. It has an excellent effect on heat-integration. The working temperature is 5”C higher than the natural sea water temperature (NSWT). In May, the contribution rate of the solar energy of working water body achieves 100%, which shows a prominent energy-saving effect. See diagram 1, diagram 2 and diagram 3 for the temperature operation.

The underground solar pond of shallow style was brought into service in April, 2002. The building area of the pond is 300 m’ with a depth of 2m. The water level is 0.5m to 1.0m deep. Farm-oriented membranes are placed at the top of the pond and wire-steel cement pillars act as the support.

The characteristic of the underground solar pond of shallow style is that it can store a great amount of water and can make full use of soil to save up heat. The temperature varies greatly between day and night, so it is fit for the water-supply of industrialized cultivation in a large scale. The working water diagram3 Temperature curves for the temperature is 3.0"C to 5.0"C higher than that of the shallow-styled solar pond in natural one in general.
