| 以西太湖湖滨典型河网区——宜兴大浦河网区为研究区域,对于该典型河网区与太湖之间的水量交换情况进行了系统的计算研究.考虑降雨因素的影响,采用考虑下垫面分类的产汇流模型,对各计算年内(2002年(基准年).1998年(丰水年),1995年(平水年),1994年(枯水年))典型河网区及其西部山地区域的降雨径流过程进行了产汇流模拟.建立起适合该河网区域的非稳态河网水量模型,结合径流计算结果,对各年内典型河网区内水流的动态变化进行了计算模拟,对典型河网区与太湖水体的水量交换情况进行系统研究,分别对顺流与逆流情况下交换水量的年内分布与年际变化规律进行了分析. |

| Abstract: |
| The study focused on the water quantity exchanges between the typical river network area (at Dapu Town, Yixing City) and the western Lake Taihu. Effect of rainfall taken into consideration, the runoff formation and flow concentration model considering various underlying surfaces was adopted to simulate the runoff process, both of the typical river network area and the nearby western hill area(2002 (base year), 1998 (wet year), 1995 (normal year) and 1994(dry year) respectively). Then the non-steady stale river network water quantity model was established by adapting to the typical river network area. Combined with the results of the runoff formation and flow concentration simulation, the water quantity model was applied to simulate the dynamic changes of water flow in the typical river network area, for each year mentioned respectively. Finally, water quantity exchanges between the typical river network area and the western Lake Taihu was ascertained. Changes of the water quantity exchanges in the year and between the years was also studied, on both co-current and adverse current conditions. |
