沙丘間
英文
interdune-
Plants growing in the semi - fixed sand dunes, on the other hand, were less branchy with a larger number of first - year shoots which were longer, and grew faster ; their leaves were longer and wider with a low length / width ratio. the characteristics of the branching system and leaf dimensions of the plants in fixed sand dunes were rather intermediary between those of the above. the frequency distribution and their frequency in the herb layer the scrubs also varied with habitats
丘間低地的黃柳灌叢當年枝平均長度增加緩慢，短枝條的比例較高，當年枝枝長頻度分佈峰值偏左，葉片短而狹，長寬比大；與之相比，分佈於半固定沙丘的灌叢當年枝平均長度增加較快，長枝條比例較高，葉片長而寬，長寬比小；固定沙丘上的上述特徵大致介於二者之間。This paper, based on the grain - size analysis and the comparative result of the mz - o scatter gram of ancient aeolian sands in milanggouwan section with the modern dunes in mu us desert, holds that fossil eolian dunes are a proxy of the dune activation, and be regarded as " desert process ", while the overlying fluvio - lacustrine and palaeosols on the dunes are regarded as inter - desert process
文中根據粒度分析及古今砂丘的mz ?散點圖比較結果，認為古代風成砂丘特別是古流動砂丘是砂丘活化的體現，視為「沙漠期」 ，而砂丘上覆的河湖相沉積與古土壤發育則可視為「間沙漠期」 。The save the dunes council of northwest indiana is one of the oldest grassroots conservation organizations in us
描述:西北印第安那拯救沙丘委員會是美國最早的民間保護組織之一。E. due to favorable condition of soil moisture, weak activity of wind and sand, and low inter - specific competition intensity resulting from repeated alternation between sand dunes and inter - dunes, the plant species richness and the plant species evenness are quite high in inter - dunes. f
由於丘間地水分條件較好，受風沙活動的影響較小，同時由於流動沙丘和丘間地的不斷更替降低了物種之間的競爭強度，就使丘間地具有較高的物種豐富度和物種均勻度。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。Accordingly, the dune deposits of the section since 150 ka bp can be divided into 38 alternate evolvement processes of desert and inter - desert periods, which accord with the sedimentary cycles of the section. it is further suggested from now climate in the area that the 38 inter - succession processes of dune deposits and fluvio - lacustrine or palaeosols in past 150 ka actually result from the alternate evolvement of the ancient east asia winter and summer monsoons in the mu us desert during the long geologic times
從這一認識出發，將米浪溝灣剖面150ka以來的砂丘堆積劃分為38個旋迴的沙漠期與間沙漠期交替演化過程，並認為，該剖面自那時以來發生的38個砂丘沉積與河湖相或古土壤的演替過程，實際上是這一長期地質時代毛烏素沙漠受東亞冬夏古代季風影響交替演化所致。Root distribution and canopy structure parameters of s. godejevii in different sandy land habitats ( semi - fixed sand dunes, fixed sand dunes and inter - dunes low land ), as well as species composition and their frequency in the herb layer of the scrubs, were compared the results were as follows : the population hi the semi - fixed sand dunes had the most developed root systems, followed by he population in the fixed sand dunes, and that hi the inter - dunes low land was the last
為了更有效地利用這一重要植物資源，本文對分佈於渾善達克沙地三種不同沙地生境（半固定沙丘、固定沙丘、丘間低地）黃柳灌叢的根系分佈，冠層特徵進行了研究，同時測定了灌叢下草本層植物種類組成及頻度，結果表明：半固定沙丘上的黃柳根系最發達（根系分佈深，數量大） ，固定沙丘的黃柳明顯不及前者，而丘間低地的黃柳根系最不發達。Through the dome runoff sediment deposition trial in three experiment stations including ningcheng, helin, dongsheng in inner mongolia, using the way of data analyzing, whether the relationship of representative influencing factor of soil erosion and the amount of soil erosion of sloping farm land in loess hilly in inner mongolia during once rainfall is exist and how much is the degree of correlation
