| 摘要: |
| 本文对洪泽湖水生植被的种群组成、植被类型、演变动态及生物量进行了调查研究。洪泽湖水生植被面积为550km2,占全湖总面积34.44%,年生产量约211×104t(湿重),即相当于4.64×1015J(能量)。另外,本文还对如何调整洪泽湖植被的组成,引进优良品种,合理开发利用水生植物资源,提出了初步意见。 |

| Abstract: |
| This paper reports an investigation on the population composition, vegetation form, evolution dynamics and biomass of aquatic vegetation in Hongze Lake.The total area of aquatic vegetation in Hongze Lake is 550km2, or 33.44% of the total lake area.The yield of wet weight is about 211×104t per year, being commensurate with 4.64×1015 J in energy.Moreover,some preliminary suggestion is put forward.including how to regulate the vegetation composition of Hongze Lake, how to introdice new fine species and varieties and how to develop and utilize aquatic plant resources. |
