watershed sediment yield meaning in Chinese
流域产沙量
Examples
- Based on the fractal character of the small watershed topographic feature , the spatial and temporal variation character of sediment yield of the watershed model , the dynamic developing process and fractal character of the topog raphic feature of the watershed model , and the coupling relationship between the sediment yield and the topographic feature of the watershed model are " studied by simulate experiment , fractal theory , high precise photogrammetry and gis technology . the validation research is conducted in chabagou watershed where the observation data of rainfall , sediment and runoff for 11 years is collected . the study provides new theory and method for the topographic feature quantitative research in the prediction model of small watershed sediment yield
本文依据流域地貌形态所具有的显著分形特征，从模拟实验出发，利用分形理论和方法，结合高精度摄影测量和gis技术，对流域模型侵蚀产沙时空变异特征、地貌形态发育过程及其相应的分形特征、流域模型侵蚀产沙与地貌形态耦合关系进行了深入研究，并以具有11年降雨泥沙径流观测资料的岔巴沟流域为例进行了验证研究，为实现从单坡面侵蚀产沙模拟、预报向流域侵蚀产沙模拟、预报转化过程中地貌形态参数的提取提供了理论和方法，为黄土高原小流域水土流失综合治理提供了科学实践依据。
