摘要：

为了更好地评价大庆湿地生态系统对太阳能资源的利用情况和大庆农业的可持续发展状况。应用生态系统能值分析理论，定量地分析和估算大庆湿地生态系统的生态效益以及系统内的物流和能流。结果表明，大庆城区湿地的价值极大，从能值分析表可以得出大庆湿地生态系统自然资源价值总计为3.13×1010￥，雨水在全部的可再生资源组成中占绝对优势，所占比例约74%；湿地水体及底泥沉积物的宏观经济价值为1.61×1010 ￥，对比能值分析表中其他项目，湿地初级生产力能值及动物资源能值小于系统投入的再生资源能值，说明该系统大部分能量用于湿地生态系统的生态服务功能，而非物质的产出。

Abstract:

In order to better evaluate the status of utilization of solar energy and sustainable agricultural development of the wetland ecosystem in Daqing. By employing the energy value analysis theory of ecological system, the author quantificationally analyzed and estimated the ecological benefit of Daqing marsh ecological system and the material flow and energy flow inside the system. The results showed that the value of Daqing City proper marsh was extremely great. From the table of energy value analysis, the author could come to the conclusion that the total natural resources value of Daqing marsh ecological system was 3.13×1010 ￥. Rainwater had an absolute advantage among all the renewable resource components, and the proportion was about 74%. The macroeconomy value of the marsh water body and the sediment deposition was 1.61×1010 ￥. By comparing with other items in the energy value analysis table, the energy value of the marsh primary productivity and the animal resources was less than the energy value of invested renewable resources. It showed that most of the system energy was used for the ecological service function of the marsh ecological system, not for the material output.
