Reconstruction and control of modern in tensive dike-pond system in Shunde

Abstract

Abstract: The traditional dike-pond system (DPS) that has been developed and practiced in the Pearl River Delta for centuries is a sustainable agro-ecosystem in low-lying area.It has an obvious land-water interaction and remarkable eco-economical effects.However,with the rapid development of urbanization and industrialization,the DPS has degraded seriously.Based on the theory of restoration ecology and ecological engineering and employing both modern sci-technology and traditional experiences,a series of ecological safe models with economic feasibility were put forward to suit the modern agro-industries,which may be set up within large scale agro-industries or among different small scale agro-industries and farmers.Taking Shunde city for instance,the main countermeasures to restore the degraded DPS should follow the development of intensive modern agriculture with the appropriate combination of dikes and ponds.The DPS should be reconstructed in high standard according to the request of agricultural modernization.An agro-ecological conservation region had been set up in Shunde city to protect the landscape of DPS,such as chosing the high quality and high effects varieties of crop and aquiculture as well as domestic animals,supporting the construction of packinghouse,market and export system to increase the market shares and competition ability and seting up the demonstration and offering information and technical advice to the manager of DPS and other businessmen with the help of local government.

Key words: Chaohu Lake, Corbicula fluminea, Bellamya sp, Eutrophication
