In order to evaluate the eco - economic adaptability of crops production , the concepts and calculative methods of ecological potential capacity and market potential capacity were put forward , the dynamic threshold value system of the indexes for the economic adaptability of different crop - region combinations was established , the calculative method of the single eco - economic adaptability indexes , the comprehensive eco - economic adaptability indexes which reflects the principle of minimum factor and the apparent eco - economic adaptability indexes and the regional comprehensive apparent eco - economic adaptability indexes which reflects practical situation of crops production were built up . 12 representative counties in jiangsu province were selected to analysis , and 77 combinations of eco - economic adaptability indexes , apparent eco - economic adaptability indexes of crop - region and 12 regional comprehensive apparent eco - economic adaptability indexes were obtained 摘要為評價(jià)作物生產(chǎn)的生態(tài)經(jīng)濟(jì)適宜性,提出了生態(tài)容量潛勢和市場容量潛勢的概念和計(jì)算方法,建立了適用于不同作物地區(qū)組合的、各指標(biāo)閾值具有動(dòng)態(tài)性的生態(tài)經(jīng)濟(jì)適宜性評價(jià)指標(biāo)閾值體系,構(gòu)建了單生態(tài)經(jīng)濟(jì)指標(biāo)適宜性指數(shù)及反映最小因子定律的綜合生態(tài)經(jīng)濟(jì)適宜性指數(shù)、表現(xiàn)作物生產(chǎn)現(xiàn)狀的表觀生態(tài)經(jīng)濟(jì)適宜性指數(shù)和地區(qū)綜合表觀生態(tài)經(jīng)濟(jì)適宜性指數(shù)的計(jì)算方法。
( 2 ) the theory foundation of iues development has explained the relevant concepts and their intensions for urban land intensive use potential estimation , made brief explanation for district location theory , land price theory , minimum factor restriction law , land pay law , ecological resource optimization law , landscape ecology theory and other basic theory ( 2 ) iues開發(fā)的理論基礎(chǔ)解釋了城市土地集約利用潛力評價(jià)的有關(guān)概念及內(nèi)涵,對區(qū)位理論、地價(jià)理論、最低因子限制律、土地報(bào)酬規(guī)律、生態(tài)資源優(yōu)化律、景觀生態(tài)學(xué)理論等基礎(chǔ)理論做了簡要分析說明。
The unsaturated soil water movement formula is adopted for calculated the transient water content within the slope . with equilibrium method the stability of soil - nail bracing structure of unsaturated soil slope is analyzed considering the connection between the shear strength of unsaturated soil and water content . genetic algorithm is introduced for searching the minimum factor of safety of natural slope and soil - nail bracing in unsaturated soil 運(yùn)用非飽和土水分子運(yùn)動(dòng)方程,求解降雨入滲條件下邊坡土體的瞬態(tài)體積含水量,又考慮到其與非飽和土抗剪強(qiáng)度的關(guān)系,利用極限平衡理論推導(dǎo)了非飽和土邊坡土釘支護(hù)整體穩(wěn)定性最小安全系數(shù)f _ ( s , min )公式。
