Abstract Using Landsat 5 TM remotely sensed data and field calibration in Beijing performed on July 6, 2004,
the authors detected the temperature distribution through the single-window algorithm and field validation. Nine
patterns were recognized on the basis of the temperature data, namely, ①water body normal temperature area, ②
water body abnormal temperature area, ③vegetation normal temperature area, ④vegetation and construction mixed
normal temperature area, ⑤vegetation and construction mixed abnormal temperature area, ⑥construction low
temperature area, ⑦construction normal temperature area, ⑧construction high abnormal temperature area, and ⑨
bare soil normal temperature area. The abnormal areas were sampled and tested in situ in detail so as to extract
the factors responsible for the abnormality. A new way has thus been found to monitor the city environment and
the living status.
