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

The specific methods : 1. to ascertain five control indications including suspended solid content, grain diameter median, oil content, iron bacteria and saprophytic bacteria by carrying out the experiment of core flow ; 2. to ascertain indications of sulfate reducing bacteria and average corrosion rate by carrying out the experiment of revolving corroded test pieces ; 3. to ascertain indications of average scaling rate and total mineralization degree by carrying out the experiment of scaling prediction and sensibility

具體的做法是：採用巖心流動試驗確定懸浮固體含量、顆粒直徑中值、含油量、鐵細菌和腐生菌五項控制指標；採用旋轉腐蝕掛片實驗確定硫酸鹽還原菌和平均腐蝕率指標；採用結垢預測和敏感性實驗確定平均結垢率和總礦化度指標。
