摘要:
为评估南四湖湿地生态系统的能量流动状况及其经济价值，采用H.T.Odum建立的能值分析理论，计算南四湖湿地生态系统多年平均的能值投入／产出，绘制南四湖湿地生态系统能值图，分析南四湖湿地生态系统结构和功能的整体特征。结果表明：南四湖湿地的投入量太阳能值为1.11×1021sej，产出量太阳能值为1.73×1020sej，初级生产力为1.61×1020sej，不可再生能源或资源（包括底泥和水体）为1.03×1021sej；同时，南四湖在水生维管束植物、以及鱼类产出方面生态效益价值显著。南四湖湿地能值投资率为0.000 9，净能值产出率为165.23，环境负载率为14.22，能值投资率低，净能值产出率高，环境负载率高，表明南四湖湿地对经济的贡献很大，区域经济发展水平较低，对环境依赖性强。
Abstract:
Adopting the theories and methods of Energy Analysis established by H.T.Odum,the average yearly energy input-output of wetland ecosystem of Nansi Lake is calculated and the energy analysis chart is drawn to evaluate the energy flow and the economic value of the lake.And the structure and function of Nansi Lake wetland ecosystem is analyzed as a whole.The result shows that the amount of the input solar value (including the sun,wind and rain) of the Nansi Lake is 1.11×1021sej,and the output solar value is 1.73×1020sej.The primary productivity is1.61×1020sej.Non-renewable energy or resources (including sediment and water) is 1.03×1021sej.At the same time,the ecological benefits of aquatic vascular plants and fish of the Nansi Lake are significant.Energy investment ratio of the lake is 0.000 9.Net energy yield is 165.23 and environmental loading rate is 14.22.High net energy yield and environmental loading rates show that Nansi Lake wetland ecosystem has a great contribution to local economy.The regional economic development level is low and vastly depends on nature environment.
