raster grid meaning in Chinese

光栅格
光栅网格

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。
