屏幕顯示真北向上Helan shan is located in the northwest of china, 37. 0 - 3 9. 6 n. and 105. 3 - 106. 8 e. its altitude ranges from 1 600m to 3 556m. the cosmo politan genera and species of higher fungi from helan shan amount to 64. 1 % and 1 9. 8 % respectively. most of them are saprophytic taxa of broad physiological adap tability. the genera belonging to the boreal areal type make up 35. 9 %, and species 52. 7 %, which indicates that the higher fungi flora of the helan shan are dominan ted by boreal elements. no tropical genera and species have been found there. the elements of europe - asia add up to 11. 5 %, while the elements of east asia - north america amount to 9. 9 % which shows close relationship of fungi between the helan shan and the above two regions. the elements of china - japan amount to 3. 1 %, whic h reflects some relations of higher fungi between china and japan. few elements e ndemic to helan shan were found but with further investigation and study, it is p ossible to find some considering its isolated geographic location and varied top ography
賀蘭山高等真菌區系地理成分中,世界性分佈屬佔64 . 1 % 、種佔19 . 5 ,他們多為適應性強的腐生菌類;歐亞北美分佈屬佔35 . 9 % 、種佔52 . 7 % ,未發現熱帶分佈的屬或種,充分顯示出該地區真菌以北溫帶分佈成分為主的特點;歐亞分佈種佔11 . 5 % ,東亞北美分佈種佔9 . 9 % ,表明該地區真菌區系與歐洲、北美洲的密切聯系;中國&日本分佈種佔3 . 1 % ,可見本地區和日本在真菌區繫上也有著聯系;本地區特有成分較少,但從賀蘭山特殊的地理位置、相對孤立的山體和復雜的地形分析,隨研究工作的深入,很可能有一些山的分佈的特有成分被發現.賀蘭山真菌區系成分與鄰近的內蒙古大青山相比較,共有種多達57種,而與地處亞熱帶向熱帶過渡的湖南莽山相比較,共有種僅有12種,更進一步說明本地區深居北溫帶,真菌區系以泛北極成分為主的特色For displaying the initial date aquired from sea chart correctly in three different display modes ( relative head up motion, relative north up motion, true north up motion ), a series of coordinate conversion are necessary. in the second chapter, data structure and various coordinates conversion are discussed in details
要使從海圖錄入的原始數據能夠在3種不同的顯示方式(船首向上的相對運動顯示方式、北向上的相對運動顯示方式和北向上真運動顯示方式)下正確的顯示出來,必然要在幾個坐標系(圖板坐標系、屏幕坐標系、平面直角坐標系和地理坐標系)中進行一系列的坐標變換。分享友人
