實驗研究的兩種菊科（ compositae ）植物（準噶爾沙蒿（ artemisiasongaricaschrenk ）和沙漠絹蒿（ seriphidiumsantolinum （ schrenk ） poljak . ） ） ，形態解剖方面的變化表現為：隨日齡增加，根長/株高比值日益增大；根系逐漸發達；體積與葉面積比逐漸增大；表皮細胞體積變小；角質層增厚；根外部出現加厚的木栓層；氣孔下陷；葉、莖部的表皮毛密布，柵欄組織日益發達；而細胞間隙日漸變小；海綿組織逐漸消失；葉面結構常為典型旱生結構? ?等葉面；晶細胞及纖維細胞數目增多；輸導組織、機械組織日漸發達；具有維管束鞘等等。We choose the forest appearance tidiness, representative stands serving as standard plots, 40 stands were set up at qinling, hanzhong, huanghong in shaanxi respectively, measure every tree in the stands, measure the actual increase by the dominance tree, the time series model of individual age and diameter of quercus variabilis was established according to the actual diameter of quercus variabilis population by the fluctuant time series, the comparison of simulation and reality value of the every stand of quercus variabilis population diameter increase through the four models, the average simulation difference within 1. 5 %, the accuracy is 97. 8 % the simulation effect is better
在陜西的秦嶺、漢中、黃龍地區選擇林相整齊、有代表性的地段作為標準地，設置樣方40個，對各樣方內的林木進行每木檢尺，通過優勢木解析的方法，測得栓皮櫟種群胸徑的實際生長量，運用起伏型時間序列分析，建立了栓皮櫟種群個體年齡與胸徑生長的時間序列模型，四個模型所得的各個樣地栓皮櫟胸徑生長的模擬值與實際值進行比較，其模擬平均誤差都在1 . 5 %以內，平均精度達到97 . 8 % ，模擬效果較好。Under the condition of different soil humidity and measuring time, a series of ecophysiological indexes, such as net photosynthetic rate, transpiration rate, stomatal conductance, the flow of water, atmospheric temperature, relative humidity, photosynthetic available radiation, and hydraulic conductivity are measured in order to find the factors which cause robinia xylem embolism
摘要在不同的土壤水分含量和不同的測定時間條件下，對刺槐的一系列生理生態指標：凈光合速率、氣孔導度、蒸騰速率、水勢、大氣溫度、相對濕度、光合有效輻射以及導水率進行測定，探求刺槐木質部發生栓塞的影響因子。分享友人
