由於實際工程巖體其固有的非線性和復雜性，使得求解對應的諸如其穩定性、變形等問題面臨較大的困難，而有關的工程結構的設計必須保證該結構在外來因素的作用下具有足夠的安全度、經濟性和合理性，這必然要求對巖體及其工程結構的受力與變形有一套量化評判體系和優化技術，抓住實際工程問題的本質特徵並建立可行的符合幾何模擬、本構模擬、受力模擬、過程模擬四原則的求解模型，通過該模型的數值模擬成果來指導巖體工程的設計、施工及運營、管理；而巖體結構面的存在使得基於傳統連續介質力學理論的理論分析和數值模擬面臨巨大的挑戰，物理模擬的試驗周期和成本也大大增加，而巖土體工程問題則成為典型的數據有限、了解程度有限類問題，這類問題的解決需要綜合應用理論分析、經驗判斷、物理模擬和數值模擬等方法，數值模擬可以完成目前許多技術手段無法完成的實驗，如參數控制，復雜條件下的邊界條件的處理，同時數值模擬具有高可重復性，且數值模擬的成本和人力開銷等遠低於物理模擬，因此研究巖土體工程問題的流形元數值模擬方法是一項具有理論和實際工程應用價值的重要課題。Gis can provide a large amount of prior knowledge about the landscape scenes, including the positions of the objects, the geometric properties, the spectral feature, the textural feature, the altitude, the information about the objects " distribution, etc. these kinds of information can help us to interpret the remote sensing image based on multiple rules, so that the interpretation can be automatic and the precision can be improved
Gis提供了遙感圖像所描述的地理區域的大量先驗知識，包括地理目標的空間位置、幾何形狀、光譜圖像的紋理特徵、高程信息、周邊環境、地物分佈規律等，這些輔助信息使得可以採用多種判別手段、判別依據對遙感圖像分類識別，從而提高遙感圖像的分類精度和自動化程度。On the basis of frequent field - studies, in the light of the basic theories of ecological design, it tells the benefits and necessity of ecological design for city squares, and demonstrates the basic aims ( aim of function, aim of image, aim of environment ) ; according to the weather and vegetation characteristics of subtropical zone, it tells the cardinal principles ( humality, sustainable development, characteristics distinguishing, integral harmony, public participation ) for the design ; with regard to the architecture enclosing, the space organizing, the boundary effects of city squares, and their size and color, this dissertation also analyzes the space and environment of city squares, and especially discusses the ideas of how to decide the size of a square regarding the problem of building big city squares blindly ; and summarizes the key points of ecological plan and design for the component factors of the space and environment of city squares, and the problem of greening of squares is paid much attention
