商品描述
This book explores the environmental conditions, particularly the climate and soils, of one of the driest regions on earth, the Central-East of the Sahara. These factors control the ecosystems and determine the land's suitability for use. The area receives only 0.5 mm of precipitation annually and contains one of the largest aquifers in the Sahara, with fossil groundwater. The region's lithology includes Cretaceous formations and crystalline rocks, largely covered by quaternary sediments. Exogenous activities have shaped various landscape types, such as ergs with different dunes, deflated depressions with playas, and yardangs.
Soils in the region are primarily formed through physical processes and are often shallow, sandy, and enriched with soluble salts. The book provides a detailed analysis of their physical and chemical properties, genesis, and relation to environmental factors and sociological aspects. It also discusses rare ecosystems, including those dependent on food imports and those that arise episodically and last for a few years.
Considering all ecological parameters, a land assessment system for irrigated agriculture is developed, along with descriptions of suitable cultivation methods and optimal irrigation systems. The book's contents are based on data from several expeditions and laboratory work funded by the German Research Foundation.
商品描述(中文翻譯)
這本書探討了地球上最乾燥地區之一——撒哈拉沙漠中部東部的環境條件，特別是氣候和土壤。這些因素控制著生態系統並決定土地的適用性。該地區每年僅接收0.5毫米的降水，並擁有撒哈拉沙漠中最大的含水層之一，內含化石地下水。該地區的岩石類型包括白堊紀地層和結晶岩，主要被第四紀沉積物覆蓋。外源性活動塑造了各種地貌類型，如具有不同沙丘的沙丘區、帶有鹽湖的凹陷地區以及風蝕丘。
該地區的土壤主要通過物理過程形成，通常較淺、沙質，並富含可溶性鹽類。這本書詳細分析了它們的物理和化學性質、成因以及與環境因素和社會學方面的關係。它還討論了稀有生態系統，包括依賴食品進口的生態系統以及那些偶爾出現並持續幾年的生態系統。
考慮到所有生態參數，書中開發了一個灌溉農業的土地評估系統，並描述了適合的耕作方法和最佳灌溉系統。書中的內容基於幾次考察和德國研究基金會資助的實驗室工作數據。
