First, the system builds the model of the bank and bottom of river, according to the river ’ s information and the information of the scene on the two side of the river. second, i read and preprocess the model file data and implement the organization and encapsulation about the space data of the virtual river. in the end, adopting to use these rending technology, such as show list, priority texture, and level of detail, i realize the real - time and vivid showing of the three dimension river ’ s virtual scene and provide abundant ways of people ’ s interacting with the virtual scene, on base of sufficiently making use of the memory of vision card and the cpu of the computer
它主要融合虛擬現實技術、三維數據可視化技術、面向對象的設計和編程技術，在vc + +平臺上，利用opengl三維圖形開發庫，以真實的城市河道現狀信息和周邊景物信息為依據，對河道、河底的三維空間數據進行三維幾何建模;然後通過讀取和預處理模型文件數據，實現虛擬場景空間數據的組織和封裝操作，並對空間數據進行優化;最後採用顯示列表、紋理優先級、細節層級模型（ lod ）等渲染技術，利用opengl的渲染特性，在充分發揮顯卡內存、處理器等各種軟硬體資源的基礎上，實現三維河流實時逼真的真實感虛擬場景顯示，並提供豐富的人機交互手段。 -
Therefor, in the light of theory and methods of karst hydrogeomorphology and the knowledge of transformation, balance and variation of matter and energy in karst drainage basin, we can examine stone forest within a specific scope of time and space, and reveal the mechanism and the development model of stone forest with the help of the principle of the mutual response processes among base - level, water flow and forms. just based on the understanding above, the paper, with a special reference to the lunan stone forest which is the best developed one in china, discusses the hydro - geomorphlogical structure of the bajiang river, geomorphological types and spacial distribution feature of the stone forest, and studies the erosion rate on the top of stone forest, soil erosion rate, sub - soil dissolution rate and their combined influences on the evolution of stone forest, furtherly brings forward and demostrates the " tri - level erosion " mechanism for the development of stone forest
正是基於這種認識，本文以我國石林發育最完美的路南石林為研究對象，研究了巴江喀斯特流域的水文地貌結構特徵、石林的形態類型及其空間分佈特徵；探討了石柱頂部的剝蝕速率（ a ） 、表土剝蝕速率（ s ） 、土下溶蝕強度（ c ）及其組合對石林發育的影響，提出並論證了路南石林發育的「三重剝蝕」機制；通過對石林發育必備條件的剖析，以及對巴江喀斯特流域演變階段的定量研究、水文地貌系統的空間耦合分析，探討了巴江喀斯特流域的演變與路南石林發育間的關系，並結合該流域的演化史，提出了巴江喀斯特流域演變與路南石林發育的模式。 -
