First the thesis elaborate the basis principles of land sustainable use, according to the natural and social economy situation, the characteristics of the land use, the aids and the principle of evaluation, we work out an index system form four aspects of productivity, protection, viability, acceptability. the weigh of indexes are defined by means of analytic hierarchy process, the standardization of indexes are defined by effective function, then, we use multi - aid decision model which mainly reflects that indictors influence on aim and multi - aid liner function which mainly reflects aim the degree of land sustainable use during 1996 and 1999 in taigu
論文從土地資源可持續利用的基本理論入手，結合太谷縣的自然、社會經濟狀況與土地利用的特點，依據評價的目標和原則，從生產性、資源保護性、經濟可行性、社會可接受性四個方面，採用專家咨詢法建立了太谷縣土地資源可持續利用評價指標體系，採用層次分析法確定了指標權重，應用功效函數法進行評價指標的標準化處理，運用反映評價指標因子對評價目標的影響程度的多目標突變決策模型和反映評價目標的可持續利用程度的多目標線性加權相結合的方法，對太谷縣1996年到1999年的土地利用情況進行了評價。 -
The establishment of efficient traffic models to reveal fundamental traffic characteristics is an essential requirement in the design, planning and operation of transportation systems. cellular automata ( ca ) are non - liner dynamical system in which space, time and state values are discrete, using simply rules, ca has attained very good results in simulating several complex natural phenomena and physical problem. that enlightens people to simulate traffic flow by ca method. urban major road performs critically on dredging traffic, therefore, it is very necessary to study the control and manage for urban main - road
交通系統的規劃、設計和運作要求有能反映交通現象基本特徵的交通模型。元胞自動機是空間、時間和狀態都離散的非線性的動力學系統，它用簡單的規則在計算機上模擬各種復雜的自然現象和物理現象，並取得了很好的結果，啟發人們用它來模擬交通問題。城市主幹道擔負疏導交通的重要作用，因此對主幹道交通流的控制與管理的研究是非常必要的。
