Lijian,

As you note, currently gdal_rasterize does not support creating the output
file, so using an existing geotiff of the target region is a reasonable
approach.

MapServer could do this if you are trying to produce output results with
1 or 3 8bit bands.  For instance if the result you seek is essentially
presentable images, as opposed to scientific rasterization outside the 8bit
domain.
