conformed by the changes of the total contributions of land use/
cover inTable 6.
It could be found from Table 6that the contribution of
temperature for the types of built-up and water was higher,
followed by fish pond and bare land in the Pearl River Delta. As
the water changed less during the study time period, it had less
influence on regional temperature changes. Expansions of builtup area became the main contributor for the regional temperature
rise (0.11 °C). Although the semi-bare land was not big for its
contribution of temperature per unit area, it still became an
important contributor to the temperature rise (0.10 °C) because of
its large area change. The calculated results showed that the
contribution of semi-bare land was almost equal to that of builtup type, both of them contributed more than 75% (0.21 °C) to the
