  1. The structures and dynamic changes of the artifical sand - fixing vegetation were studied based on the follow views : components of vegetation community, plant diversity, life - forms of vegetation, trends of plant growth, characteristics of the vertical and horizontal structure of vegetation, relationship between the vegetation community and environment ( including soil moisture temperature etc. ), relationship between the vegetation community and characteristics of plant physiological activities. some results were showed as follow : 1. components, diversity and life style of artificial vegetation in shapotou region the marked changes of artificial vegetation have taken place during more than 40 years, since the establishment of sand - fixing vegetation

    本文以騰格里沙漠東南緣寧夏中衛縣沙坡頭地區人工固沙植被作為研究對象，採用傳統生態學的野外調查方法，從植被群落的組成、多樣性、生活型、群落生長動態、垂直結構特徵、水平結構特徵、群落結構與周圍環境（土壤含水量、溫度）相互關系及其與植物自身生理生態適應特徵關系等多個角度研究了人工植被群落的結構及其動態變化，取得了如下研究結果： 1 、植被群落組成、多樣性及生活型：沙坡頭地區人工植被經過近50年的演變，從流動沙丘到固定沙地，沙地植被的動態變化經歷了從人工植被到人工?自然植被的轉變，從人工植被建立初期的少數幾種引種植物到現有30多種植物，隨著固定沙地時間的延長，植物種類日趨豐富，並且人工植被在15 25年、 40 50年兩個階段，物種的周轉速率最大，即群落結構變化最大。
  2. Haloes in the two accretion phases show systematically different properties, for example, the circular velocity vh increases rapidly with time and approximately equals the inner circular velocity vs in the fast accretion phase, but remain almost constant and less than vs in the slow accretion phase : the inner properties of a halo, such as rs and ms increase rapidly with time in the fast accretion phase but change only slowly in the slow accretion phase : the halo concentration changes slow in the fast accretion phase, but increases rapidly with the hubble expansion in the slow accretion phase. the inner structure and potential well associated with a halo is built up mainly in the fast accretion phase, while a large amount of mass can be accreted in the slow accretion phase without changing significantly the inner properties and the potential well

    ~ 4 ，其束縛能和具有相同圓周速度的等溫球大致相等; （ s ）在這兩個階段，暗暈的行為特徵迥異（例如，圓周速度均『在快速吸積階段增長迅速且略大於內部圓周速度: 、 ，而在緩慢吸積階段基本恆定甚至降低，且小於、 、 . : 、和呱在快速吸積階段增長迅猛，而在緩慢吸積階段增長滯緩） : （ l ）一個暗暈的內部結構和引力勢阱主要是在早期的快速吸積階段成長起來的，雖然在緩慢增長階段可以吸積大量的質量（超過10倍） ，但這並不顯著地改變其內部特徵和引力勢阱
  3. ( 2 ) it shows strong positive correlation at 32 years periodic scale between the precipitation and sst in nino3, while the periodic characteristics are more distinct at 4 years though it is mostly positively correlative then ; in a shorter time scale period, the correlation between the precipitation in heilongjiang and soi is the regular transforming of positive and negative correlations, while at a longer annual or decades scale, the correlations, though mostly negative, are periodically positive

    黑龍江省降水與nino3區海溫的相關，在32a周期尺度上，表現為較強的正相關，而4a尺度上雖以正相關為主，但相關的階段性比較明顯；在較小的年際尺度周期上，黑龍江省降水與soi之間表現為正、負相關有規律的轉換；而在較大的年際尺度和年代際尺度上，兩者的關系則以負相關為主，但也存在階段性的正相關。
