本論文依託巫溪縣水土保持生態修復項目，運用模糊層次分析方法，進行退化生態系統的景觀健康評價體系設計與健康等級分析；通過對比研究巫溪縣與另一個生態修復試點縣? ?璧山縣的土地景觀空間格局分析，揭示巫溪縣土地利用格局上的退化特徵；提出與水土保持治理相結合起來的生態恢復模式；引用土壤肥力質量指數，對生態修復區不同生態恢復演替階段群落及不同時期坡改梯、休耕地與封山育林三項生態修復措施的土壤肥力質量分析與對比。Then, using recursive arithmetic calculated reliability indices for directory tree, the method was realized by vb program ; the other is a method of reliability evaluation by interval arithmetic, which is the use of interval arithmetic to evaluate reliability, and the computation theory is also given. during the calculation, interval number replaced the component " s parameter and it takes into consideration the uncertainty of all of the parameters. in the study of power distribution system configuration, a new configuration model is set up which takes into account simultaneously the losses minimization and system reliability, then improved genetic arithmetic is described detail and of advantage for solving this problem
在配電網可靠性評估的研究中，提出了兩種實用的配電網可靠性評估方法：其一是利用網路分層和遞歸演算法理論，使用高級語言進行程序設計，提出了一種基於vb編程的配電網可靠性評估方法，該方法通過程序實現了網路拓撲結構的分層等效和可靠性指標的遞歸計算，使整個計算過程得到了簡化，並且界面窗口的可視化，使得評估過程便捷、形象；其二是提出了一種基於區間演算法的配電網可靠性評估方法，該方法是一種利用區間理論計算配電系統可靠性的不確定性評估方法；文章給出了區間運算的原理；討論了配電系統中區間數據的來源途徑，並用區間數代替元件的可靠性參數，對輻射形配電網進行了可靠性評估。
