| 摘要: |
| 根据1987—1988年环太湖河道水质、水量实测资料以及环湖主要河道的流量和水质的历史资料,结合平原水网地区的水情特征,提出了环太湖河道污染物负荷量的计算方法,并分析探讨了不同设计水情下环太湖河道污染物负荷量及其时空变化。结果表明,污染物负荷量与水情关系密切,枯水年的河道入湖污染物负荷量大于丰水年。环湖22条主要河道的入湖污染物负荷量占全部河道入湖总量的72％—91％,且不同污染物入湖负荷量的分布不尽相同。 |

| Abstract: |
| The spatiotemporal changes of the pollutant load in these rivers, their analysis and computation on the basis of the observed data on the water quality and Water quantity during 1987 - 1988, and the historical data of flow and water quality in the main rivers around Taihu Lake, and the characteristic of different water regimes in the plain river network area, are presented in this paper. All the results show that the pollutant load has close relationship with the water regime and that the pollutant load in a low-water year is greater than that in a high-water year. The inflow pollutant load of the twenty-two main rivers around Taihu Lake is 72% - 91% of all river-derived pollutant loads. The distribution of inflow load of the different pollutants is not exactly the same. |
