This paper , based on the grain - size analysis and the comparative result of the mz - o scatter gram of ancient aeolian sands in milanggouwan section with the modern dunes in mu us desert , holds that fossil eolian dunes are a proxy of the dune activation , and be regarded as “ desert process “ , while the overlying fluvio - lacustrine and palaeosols on the dunes are regarded as inter - desert process 文中根據粒度分析及古今砂丘的mz ?散點圖比較結果,認為古代風成砂丘特別是古流動砂丘是砂丘活化的體現,視為“沙漠期” ,而砂丘上覆的河湖相沉積與古土壤發育則可視為“間沙漠期” 。

The general characteristics of the grain - size distribution of different sedimentary facies , es pecially the variations of the parameters mz ( mean particle diameter ) and o ( standard deviation ) clearly show that the fluvio - lacustrine facies and palaeosols usually become finer in particles and worse in sorting than the aeolian sands 該剖面不同沉積相粒度的一般分布特征尤其是粒度參數? mz 、的變化明顯表現出,河湖相或古土壤通常要較風成砂顆粒細化,分選相對較差。

At 3342 meters , mount etna is the highest peak , and europe s largest active volcano . a number of small islands located around sicily are popular tourist resorts , the volcanic aeolian or lipari archipelago being the largest group . the extensive coastline ranges from rocky cliffs to sandy beaches , but sicily also offers other fascinating natural sights such as alcantara gorge near taormina , various caverns carburangeli near carini and others around sicily and on the surrounding islands , and the grey mud flows formed by sporadic geysers that give maccalube , near aragona , its moonlike appearance . . 一是首府帕勒摩palermo ,往近郊的monreale或segesto遺跡都很方便二是卡塔尼亞catania ,有南義米蘭之稱,義大利作曲家貝里尼出身此地,且北有陶美尼taormina小山城,南有薩拉庫撒siracusa三是阿格利真托agrigento ,神殿之谷絕對值得一訪,有諸神的居所的美稱。

The dissertation uses mineralogy principle to research the content and character of aeolian , in order to realize the original of aeolian ; and also uses existing multiple information and basic materials of the research region ( including data of geology , geography , hydrology , meteorology , economy , human culture and dem ) , to study the driving factors of the desertification in the region and the connection between the desertification and its driving factors with the methods of probability , statistics , curvilinear estimation , logical analysis , principal component analysis . on the basis of the ca ( cellular automata ) method , the dissertation constructs a corresponding mathematical model of the desertification - geoca desertification model , and realizes the dynamic analysis and evaluation of the desertification evolution of the capital and its neighboring area 在方法上運用礦物學研究的基本方法和原理對研究區風沙成分進行了初步分析,探討了研究區風沙物源的主要成因與特征;根據已有的多元信息基礎資料及研究成果(地質、地理、水文氣象、經濟、人文以及dem數據等) ,運用概率統計、層次分析等數學方法綜合研究了土地沙漠化與各驅動因子之間的相關關系,確定了研究區土地沙漠化主要驅動因子,在此基礎上運用元胞自動機ca ( cellularautomata )的基本原理,建立土地沙漠化演化數學模型: geoca - desertification模型,對首都及鄰區土地沙漠化演化趨勢進行了探索性模擬分析與評價。

Mz , a , sk , kg and sc / d ( ratio of the sum of silt and clay to sand ) of fluvio - lacustrine , palaeosols and aeolian sands constitute an interlocking , multi - fluctuation process curve with peak and valle y values : the < & value of mz , o and sk values often increase accordingly from aeolian sands to its overlying fluvio - lacustrine facies or / and palaesols , the kg value heightens , too , and the sc / d value also basically consists with its change steps 河湖相和古土壤與風成砂的mz 、 、 sk 、 kg以及sc d (粉砂粘土之和與砂的比值)構成一峰谷交替、犬牙交錯的鋸齒狀多波動過程線:常常是由風成砂至上覆河湖相或和古土壤, mz的值、 、 sk值相應增大, kg相應增高, sc d值亦與之變化步驟基本一致。
