摘要基於對多年來風火山地區的多年凍土資料,研究了天然地區和路基下的凍土上限變化情況以及多年凍土的融化狀態,並定量分析了進入多年凍土內的熱狀況。The results demonstrate that the upper limit of permafrost in this area had declined from 1970s to the middle phase of 1990, and permafrost has appeared degenerate tendecy, but since middle 1990s, permafrost have a stable state ; ground temperature of roadbed near the earth surface is higher than that of the natural ground, thawing time of roadbed near the earth surface is longer than that of the natural ground, the heat income within the permafrost is greater than the heat release from the permafrost during anannual period, the heat accumulation within the permafrost is temporarily appeared as temperature rising, but with the heat accumulation within permafrost growing up year by year, permafrost temperature will become higher gradually, and strong thawing of permafrost could be happened in the region
結果表明:風火山地區從20世紀70年代到90年代中期凍土上限下降,凍土出現退化現象,從90年代至今凍土趨于穩定;路基近地表地溫明顯高於對應天然地表下的地溫,路基近地表經歷的融化期長于對應天然地表,進入多年凍土區的熱收支也呈現出吸熱明顯大於放熱的周期性變化,進入多年凍土的熱積累暫時以增高地溫耗熱為主,但隨著凍土吸熱量的逐年積累、凍土溫度的不斷升高,本區凍土可能發生強烈融化。There are 11 display areas inside the museum, covering subjects such as the formation of various types of hot spring, the history of peitou s development as a spa, local industries such as peitou porcelain and lincao rush weaving, the volcanic geology of the area, hot springs around the world, and most particularly, the mineral known as hokutolite or " peitou stone.
