4. Conclusions
In Yinchuan Plain experimental zone, 107 pattern spots of new increased construction land were extracted
through CBERS and P6 images data. the minimum spot average area of new construction land change
monitored by 20m scale remote sensing data based on CBERS and P6 multispectral data as the representative
is about 6 acres. Through the contrast analysis, the spatial resolution of CBERS and P6 multispectral data are
higher than BJ-1 multispectral data, so whether the image extraction accuracy or business meeting precision
are greatly improved, especially the ability identifying new construction land use change further strengthens,
shows in the recognition of the smallest pattern area reduces and the recognition accuracy increases.
