中文拼音 [shāqiūjiāndīde]
沙丘間低地
英文
lowland in sand dune-
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。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。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。
