略论稻田养鱼与农田生态

Rice paddy pisciculture can bring out the latent power of production of rice paddy ecosystem,improve the relationships among organisms in the rice field,change the direction of energy conversion and coordinate the relationship between organisms and abiotic environment,rice,the largest primary producer,can keep organic contact with fish,the largest consumer,after carying out rice paddy pisciculture.In this way,anecological system is formed in wich rice and fish live together.The method not only adapts the change of natural conditions but also avoids environmental polution.Because of its obvious economic,ecological and social benefits,we must fully understand this method and carry it forward with appropriate measures.
