本文從南方紅豆杉種群生態學的角度、主要應用數學生態學的方法探討南方紅豆杉種群的數量特徵，包括南方紅豆杉種群年齡結構、種群空間格局（探討分佈格局動態規律與生境相互關系） 、不同立地條件下種群優勢度增長趨勢、生態位寬度、生態位相似比例、生態位重疊、空間占據能力及種間競爭等，分析其目前現狀及瀕危原因，期望為南方紅豆杉野生資源的保護和擴大、營造人工林及可持續利用提供理論基礎，也為瀕危植物種群生態學的研究提供參考。Both oxyopes sertatus and harpactor fuscipes are important predators of common cutworm ( spodoptera litura ) on tobacco. the effect of several interference factors on the predations of o. sertatus and h. fuscipes on the larvae of s. litura were examined in laboratory. the results indicated that there were significant mutual interferences on their predations with the existence of other individual in the same / different species. as the number of the predator increased, the predation rates decreased significantly. the interference coefficients ( m ) within h. fuscipes and within o. sertatus were 0. 7278 and 0. 6911, respectively, while the interference coefficient ( m ) between o. sertatus and h. fuscipes was 0. 9464. these results showed that the effect of mutual interference on predation in interspecies was more obvious than that in intraspecies. the number of prey captured and the predation rate of predator dropped with increasing the number of tobacco stalks. this result suggested that spatial heterogeneity was also an important factor affecting the predation of predator on prey
斜紋貓蛛和紅彩真獵蝽均是煙草上斜紋夜蛾的重要捕食性天敵.室內測定幾種干擾因素對斜紋貓蛛和紅彩真獵蝽捕食作用的影響，結果表明這些干擾因素對斜紋貓蛛種內、紅彩真獵蝽種內和兩種捕食者種間的捕食作用均有明顯的干擾作用，隨捕食者數量的增加，其對斜紋夜蛾捕食作用率顯著降低.斜紋貓蛛種內的干擾系數和紅彩真獵蝽種內的干擾系數分別為0 . 7278和0 . 6911 ，而兩者種間的干擾系數為0 . 9464 ，說明兩者種間的干擾作用要明顯高於同一種捕食者種內的干擾作用.兩種捕食性天敵對斜紋夜蛾的捕食量和捕食作用率隨煙草莖桿數的增加而降低，表明空間異質性同樣是影響兩種捕食性天敵捕食作用的一個重要因素The intense eluviation and weathering of soil with groundwater and run - off result in the enhancing of capacity of transference of some elements, such as si, al, fe, mn. the chemical reactions of the colloid particles in the soil water make those crannies or holes filled by some epigenetic clay minerals and quartz. then a great deal of white reticulate clay comes into being in the quaternary laterite of the dongting basin

該影響過程可總結為：增發宣告前股價先顯著上漲，大多是被故意拉高，到增發宣告前一個月時漲幅逐漸變小，至增發宣告前一周左右轉為小幅下跌，等宣告后股價開始大幅狂跌，而後持續至增發宣告后一個月左右，空方力量開始變弱，下跌程度減少，市場情況慢慢開始轉好，隨著時間的推移，這種下跌變得越來越不明顯。This work follows professor wang naiyan " s ider of laser energy storage ring. the new method of ultra - short laser pulse train combination is developed from multiangular optics system
