本課題在對現有路面結構狀況和使用狀況進行調查，並對路面使用性能和破壞原因進行分析的基礎上，結合秦皇島地區的土質、水文條件，確定重型擊實標準條件下土基回彈模量值，依據不同等級土基對路面基層或底基層的厚度產生大致相同效應的原則，將秦皇島地區地基強度等級劃分為三級並將本地區公路分成三個區。在廣泛收集交通量及組成的觀測資料，了解交通特性，進行交通參數分析后將交通量等級劃分為四級。 -

The correlation coefficients between soil moisture regime and soil n2o emission rate were positive in the lower soil moisture regime ( 8 to 58 percent wfps ), and soil n2o emission rate turned weaker and weaker when above the field moisture capacity ( 106 percent wfps ). the highest n2o emission rate occurred in the field moisture capacity. soil n2o emission rate was higher in 30 than in 10 in the lower soil moisture regime ( 8 to 58 percent wfps ), however, the trend was reverse when above the field moisture capacity ( 106 percent wfps )
5水分含量低時（ 8 58 wfps ） ，土壤中n20釋放速率與土壤濕度呈正相關，並且隨著溫度升高釋放速率增大；土壤濕度接近田間持水量（ 58 wfps ）時，釋放速率最大；超過田間持水量（ 106 wfps ）時， n _ 2o釋放速率顯著降低，且30時的釋放速率小於10時的速率。 -
4. soil n2o discharge flux responsible for the different treatments were affected by the different soil factors in the winter wheat growing stages. under no planting conditions, the moisture regime in the 0 to 5cm soil layer mostly made the soil n2o discharge flux adding in the mulch treatment, and the content of nitrate nitrogen in 5 to 10cm soil layer in the no mulch treatment
4在冬小麥生育期內，影響不同處理土壤中n _ 2o排放通量的主要土壤因子為：無種植情況下，覆膜所導致的膜下（ 0 - 5cm ）土壤水分積累是引起土壤中n _ 2o排放通量增加的關鍵；無膜時較淺層土壤（ 5 - 10cm ）中no _ 3 ~ - - n濃度對土壤中n _ 2o的排放至關重要。 -

Basis on the statu quito, the basis of the selecting title, the main theoretical foundations and the researching approachs, the thesis analyses the advantage of the development animal husbandry and the existing questions in jiuquan oasis. the author thinks the restricting factors in animal husbandry development are the limited meadow area, the serious soil erosion, the land determinations, the worse management regime, the severe hazard on mice, the fluctuating product in meadow and so on. and then the author has appraised the ecological fragility in jiuquan oasis
論文在論述了酒泉綠洲畜牧業的研究現狀、選題依據、主要理論基礎及研究方法的基礎上，分析了酒泉綠洲畜牧業發展的有利條件，認為人工、半人工草場面積小，水土流失嚴重，土地退化，草畜比例失調，草場退化，草原管理制度不健全，鼠害猖獗，牧草產量年度變化大，產草量和草場利用季節不平衡，生產經營理念落後，成為酒泉綠洲畜牧業發展存在的主要問題，並對酒泉綠洲的生態脆弱性進行了評價。 -
Based on five years regional water - salt monitoring data and related hydrological and weather information in the smaller scale experiment zone ( shahaoqu ), the regional water - soil ( salt ) environment regime including grounder water table depth, water quality, superficial layer ( 0 - 40cm ) and middle layer ( 40 - 70cm ) soil moisture and saline concentration are simulated, tested and predicted using bp model. at the same time, the rbf model is be used to calibrate the results of bp
以一個小尺度試驗區的多年區域水鹽監測資料及水文氣象資料為建模依據，對試區非凍期（作物生長期）的地下水位、地下水質、土壤水鹽（ o - 40cm ， 40 - 70cm ）的水-土（鹽）環境狀況進行了較為深入全面的模擬預測，並進行了rbf模型預測結果的對比。 -
