Huadu experienced economic soaring during 1999-2009. The ever-changing urban landscape pattern impacted the distribution of the thermal environment. The land surface temperature (LST) and land use types in the study area were obtained from Landsat TM/ETM+ remote sensing images. Using the mean-standard deviation method, land surface temperatures were classified and the thermal centroids of low and high temperatures were calculated. And the moving paths of the thermal centroids during 1999-2009 were compared with that of the construction land centroid. Visual landscape metrics, including SHDI, construction land PLAND, FRAC_MN, and DIVISION, were obtained by moving window to analyze their correlations with LST. The results show that: the southern part of Huadu was strongly impacted by human activities. Land use was not the single factor which influenced the distribution of land surface temperature. SHDI and LST were positively correlated, even though the increasing degree of landscape diversity would cause the decrease of the relevance. The correlation between LST and construction land PLAND/DIVISION was stable. The regions with large construction land PLAND or low construction land DIVISION were usually high temperature regions. With the increase of the shape complexity and the area of the construction lands, the correlationship between LST and construction land FRAC_MN become stronger.

Key words: landscape pattern, thermal environment, moving window, mono-window algorithm, Huadu
