| 摘 要： | 为了分析鄱阳湖区砂源分布情况，为鄱阳湖采砂规划提供资料，对鄱阳湖区悬浮物含量进行了测量。根据泥沙沉速和含量的关系，利用GIS技术，对整个鄱阳湖区的含沙量进行了模拟分析。结果显示：鄱阳湖的悬浮物含量范围为1.553 4 ~ 94.071 6 mg/L，沉速为0.002 7~0.488 3 cm/s；以永修松门山为界，以北地区含沙量较大，以南地区含沙量较小。在含沙量较大的星子县沙岭、永修县松门山和都昌老爷庙地区所围成的三角区域不适宜采砂。通过对生态、航运、采砂经济效益的综合分析，对鄱阳湖区采砂区域进行了初步规划，鄱阳湖的年采砂量不应超过1 100万t。

| Abstract: | In order to analyze the distribution condition of sand sources in the Poyang Lake and provide data for sand mining planning,the suspended materials in the lake were measured.Based on the GIS platform and by the utilization of relation between settling velocity and content of sand,we simulated the sediment concentration of Poyang Lake.The result show that the suspended solid contents range from 1.5534 mg/L to 94.0716 mg/L,the settling velocity ranges from 0.0027cm/s to 0.4883cm/s.Bounded by Songmen Mountain ... |
