| 英文摘要 | We analyze the distribution of temperature and heat flow of the sea floor sediment in the area of East China Sea slope and West basin area of the Okinawa Trough. Based on the Sonar Buoy and OBS data, 6 velocity layers are recognized, each of which has velocity of 1.8(1.8 similar to 2.2) km/s,2.2(2.0 similar to 2.5)km/s,2.8 (2.7 similar to 3.2)km/s,3.4 similar to 3.6km/s,4.2(4.1 similar to 4.7)km/s and 5.1km/s, respectively. The upper velocity layer of 1.8 similar to 2.2 km/s corresponds to the Quaternary sediment stratum. The layer with velocity 3.4 similar to 4.2km/s is the Pliocene sediment stratum. The area that is suitable for stable existence of gas hydrate by the temperature and pressure is 70,000km(2) about 1/10 the total area of East China Sea. The thickness of the stability zone ranges from 400m (Middle Part of Okinawa Trough) to 1100m (North and South Part of Okinawa Trough). The Quaternary and Pliocene layers are suitable for stable exitence of gas hydrate. According to the tectonic stability and heat flow, the north part and south part of the Okinawa Trough are the most perspective area for the gas hydrate explorations.; We analyze the distribution of temperature and heat flow of the sea floor sediment in the area of East China Sea slope and West basin area of the Okinawa Trough.
