About thirty years ago,we were badly shaken by a forest fire on the street of Kukuan .The fire was burning all the night, they said ,the fire fighters praised that the fire was controlled in the limited area, though the nightmare always gave me a thrill.
June 23,2014 ,we made a trip to Yellowstone National Park and surprised that the hills were covered with little pine trees ,the guider said that in 1988,the forest fire in Yellowstone had damaged 26% of the park trees and the pole pine trees grow slowly. So terrible !
Watching the program " The New Silk Road."on the CCTV ,showed about the Chinese archaeologists who found out a great graveyard of a thousand tombs over 1600 years ago on Du Land of Qinghai Province .All the tombs were built with a layer woods of Cypress tree on a layer of stones and the nobler man used the bigger and more woods,based on the fact to suspect that the palace buildings would use the more giant
woods. Due to the Cypress tree grows slowly ,the circle is 15 cm in diameter needing 200 years and 60cm in diameter needing 2500 years. We could suppose to 1600 years ago,the Tsaidam Basin was covered the plenty of thick forest instead of the wild and dry plateau now.
Don't let the history repeat itself, we are reserved and take things very seriously to protect our forest and friendly environment.
森林是珍貴的
大約三十年前，我們曾極度驚恐的站在谷關街上看熊熊烈火焚燒森林，整夜火光衝天。據說消防人員慶幸森林大火被控制在有限的區域內燃燒，雖然如此，那場夢魘常讓我一想起就不寒而慄。
西元二O一四年六月二十三日，我們到黃石國家公園旅行，非常驚訝所見山頭覆蓋的是一片小松樹林，導遊説在一九八八年黃石國家公園曽發生森林大火，燒毀了百分之二十六的森林，松柏樹長得很緩慢。好可怕！
看中國中央電視台的節目「新絲綢之路」，報導了中國考古學家在青海省都蘭發現一千六百年前古墓地，估計有千座墓葬。所有的墓穴都是一層石頭上疊一層柏木頭。層級越高的貴族堆疊的層次越多，使用的木頭越粗大。基於這事証推論宮殿巨室建築會使用更巨大的木頭。根據柏樹生長緩慢，年輪直徑十五公分的柏樹需生長二百年，直徑六十公分的柏樹需生長二千五百年。如此推論，一千六百年前，柴達木盆地應是覆蓋大量茂密的森林，而不是今日所見乾燥杳無人跡的荒野高原。
不能讓歷史重演，我們得謹慎保守嚴肅的看待森林保護和友善環境這件事。
