- Abstract:
- In this paper, Landsat7 ETM+ and single band image SPOT5 of Guiyang City in 2011 were dealt with correction, fusion, and remote sensing interpretation using 3S technology to get the residential land of the study area, and the evaluation system of residential land on economical and intensive utilization was established. Eco-environment effect of residential land under economical and intensive utilization levels were quantitatively analyzed using the method of slope analysis, landscape index, vegetation index and vegetation coverage analysis. The results showed that: (1) intensive utilization degree of residential land was higher, accounting for 81.319% of the total area, followed by moderate use; (2) residential land mainly distributed in slopes with gradients ranging from 0° to 10°, slope gradient and slope use degree had the positively correlated relationship; (3) residential land landscape pattern was broken, and the utilization degree was positively related to basic relationship on number of patches, patch density, patch average area, landscape shape index, landscape richness and landscape concentration; (4) the NDVI and its utilization degree of residential land were positively correlated. Overall, eco-environment effect of residential land is positive.
