云南省两种地貌类型下河流悬沙浓度变化状况与治理对策

Suspended Sediment Concentration(SSC) Change Characteristic and Countermeasures of Two Kinds of Landform of Yunnan Province

分析了云南省大理白族自治州漾濞江流域和文山壮族苗族自治州盘龙河流域的河流悬沙浓度的持续变化状况,结果表明:漾濞江流域河流悬沙浓度逐年减少,而盘龙河流域却一直在攀升。结合区内的自然与经济状况,探讨了相应的治理对策。

Taking the Yangbi River of Dali Bai Minority Autonomous Prefecture and the Panlong River of Wenshan Zhuang and Miao Minority Autonomous Prefecture as the examples to analyze the suspended sediment concentration （SSC） change characteristic of Yunnan province, the results showing： The SSC of Yanbi River reduces slowly whereas the Panlong River increases continuously. Finally, the authors combine the natural and economic condition of the studied area and puts forward corresponding countermeasures.
