| 对连云港市宋庄镇有机海水养殖基地的海水围塘南美白对虾—缢蛏—梭鱼混养系统和南美白对虾单养系统的能量收支与利用效率进行了研究。结果表明,在有机水产养殖方式下,混养系统中能量输入、输出分别为10.54和8.37MJ/m2,单养系统能量输出、输入分别为13.45和10.72MJ/m2。混养系统的光能利用率、光合能转换效率、生物能转换效率、总能转化率和底泥沉积率分别为0.18%、34.51%、48.11%、16.89%和62.41%,单养系统相对应的数据分别为0.19%、24.95%、24.04%、11.17%和68.54%。混养系统除光能利用率外,其他指标均优于单养系统,底泥沉积率亦小于单养系统。从综合生态经济指标来看,混养系统也优于单养系统,但2者综合生态经济指标(EY)均小于1,混养和单养系统都具有提高经济效益和生态效益的潜力。 |

| Energy budget and conversion efficiency were examined in organic polyculture of whiteleg shrimp Penaeus vanamei，mugilid fish Liza haematocheila and razor clam Sinonovacula constricta in ponds in Lianyungang ,China. The results indicated that total solar radiation energy input and output in polyculture system were 10. 54 x106 J/m2 and 8. 37 x 106 J/m2，While they were 13.45 x 106 J/m2 and 0. 72 x106 J/m2，In monoculture system，respectively. Organic shrimp polyculture system was significantly higher in photosynthetic energy conversion rate (34.51%vs. 24. 95 %)，biomass conversion efficiency (48.11%vs. 24. 04%)，and total energy conversion rate(16. 89% vs. 11.17%)，when compared with monoculture system. The photosynthetic energy efficiency and sediment energy in polyculture system (0. 18% and 62. 41%)were lower than in monoculture system ( 0. 19 % and 68.54%).Integrated ecological and economic index for both systems was less than 1 .It is concluded that both organic shrimp polyculture and monoculture systems can produce comparable ecological and economic benefits. |
