【Abstract】 A dike-pond system is a particular artificial ecosystem of land-water in- teraction,and also a special stero-cultiviting breeding system,so it has the characteristics of both land ecosystem,and fresh water ecosystem.The system has complicated structure and multi-levels including land cultivating levels and water-body breeding levels.As for the cultivation forms,it may be one of the production structures with the most levels and the highest form. The input and output of substances and energy of the dike-pond system are basically balanced.The sections of the system coordinate and promote each other.Because each unit area can give various agricultural and aquatic products,and high production yield,it is one of the important ways of saving farmland.更多还原
