Paper Abstract

This paper analyzes the geothermy in east Fujian province, applying the remote sensing data in thermal infrared wave-band (Ch4 10.5 - 11.5 micrometer) of meteorological satellite NOAA- 9. This region is 60,000 square kilometers. On the 101 I2S image processing system, the author processed the remote sensing information recorded in daytime of December 17 and at night of December 18, 1985 by the National Center of Meteorological Satellite from the NOAA-9(CH4) flew across the Fujian Province. The content of processing is: evaluating the maximum of gray level; extracting the information of close level slicing; scaling operation; pseudo-color slicing and pseudo-color image compositing, etc. A series of thermal islands of geothermy distribution images in which the temperature decreased by degrees were obtained by processing. Geographical distribution of thermal islands of geothermy tallies with the thermal springs known, controlled by EW trend and NE trend crustal structure. To the south of Xianyou- Zhangpin EW trend fault zone, the temperature of thermal islands of geothermy is higher than that to the north. Effected by Changle-Nanao NE trend deep fault zone, the thermal islands of geothermy show intermittent zone distribution along NE trend, and from southeast to northwest the temperature decreases by degrees. The thermal islands of geothermy with the highest temperature are located in Zhangpu, Yunxiao, Zhaoan and nearby areas, and here are the intruded rock and extrusion rock in these areas.
