The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes, revealing that in different planting modes their densities, heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a. ordosica annually grew in a s - shaped cure and the young shoots of c. korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c. korshinskii and a. ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a. ordoska appeared to have obviously lower coverage and biomass that the other three quadrats
摘要對騰格里沙漠東南緣2種人工植被檸條和油篙在4種配置方式下地上部分的生長動態進行了研究，結果表明：不同配置方式下它們的密度、高度、冠幅和生物量基本不變或略微呈下降趨勢；油篙新梢的年生長動態呈s型曲線，檸條新梢春季生長速度較快， 7月份以後生長速度緩慢或基本停止生長；檸條、油篙地上生物量和葉面積指數的年變化均表現為雙峰型， 4種配置方式下共有8種1年生植物人侵，並具有較高的植被蓋度；同其它3個樣地相比，純油篙樣地1年生植物的密度、蓋度和生物量明顯偏低。 -
