subcatchment meaning in Chinese
支流集水区
Examples
- Project i is the conventional subcatchment method
方案是基于传统子流域的方法建立的。 - Project ii is modified subcatchment method by interpolating rain - gauge data to each grid , then averaging rain values over all grids within a subcatchment as the input of the ~ subcatchment
方案是在方案的基础上，先将雨量离散到栅格单元，再将雨量划归到研究流域的各子流域作为雨量输入。 - On the platform of digital basin derived from raster dem data , - a grid - based hydrological model and a subcatchment - based hydrological model were used to study the effects of spatial variability on runoff process on such aspects as precipitation , model parameters and soil evaporation
在构建的数字流域平台基础上，建立分别基于子流域离散和栅格离散的数字水文模型，从而分析研究降水、模型参数和土壤蒸发的空间不均匀性对模拟水文过程的影响。 - The parameter in the xin ' anjiang model , imp , was extracted directly from above land use / cover data . another parameter , sm , in each subcachment and in each raster grid was obtained from the relation between sm and the ratio of forest land area to subcatchment area . thus , a semi - distributed hydrological model and a distributed hydrological model were established to analyze the effect of some parameters in xin ' anjiang on runoff process according to the spatial variability of land surface characteristics
将遥感技术获取的土地利用和地表覆盖一公里栅格信息与数字高程模型数据进行空间配准，然后通过构建林地面积比与新安江模型参数sm的关系间接确定各子流域及各栅格单元的的sm值，新安江模型参数imp由配准好的土地利用和地表覆盖信息直接提取，由此建立方案与方案，来分析受下垫面覆盖的空间不均匀性影响的模型部分参数是如何对模拟水文过程产生影响的。
