Prognosticated dimensions to investigate from the period of year, the overground amount of organic carbon on unit area is big, the underground soil organic carbon on unit area is biger.So,Tamarix is one of important carbon sink at arid land.

从年周期观测尺度来考察，单位柽柳林面积中的碳蓄积量较大，林下土壤中的碳蓄积量更大，因此，柽柳是干旱区重要碳汇之一。

The results shoed that the major 29 plant species in the wetland belonged to 27 genera, 12 families and 4 ecological species groups, and most species had low abundance. Populus euphratica, Tamarix hispida, Phragmites australis and Nitraria sibirica were the most common species.

结果表明，研究区的29种主要植物，隶属12科27属，分为4个种类组，大多数物种丰富度较低，其中胡杨、毛柽柳、芦苇和西伯利亚泡泡刺是最常见的种类。

The distribution patterns of Tamarix chinensis population under the environmental gradient of different water table depth were analyzed using two fractal analysis methods-box dimension and information dimension.

利用计盒维数和信息维数两种分形方法分析了黄河三角洲湿地柽柳种群的空间分布特征及其随水深梯度的变化。

The water table depth of -1.55 m may be a thresh old of the distribution patterns of Tamarix chinensis in wetlands of the Yellow River Delta.

Photosynthetic rate P(subscript n, transpiration rate, stomata conductance G(subscript s, active photosynthetic radiation, relative air humidity, air temperature and water use efficiency of three tree species Platycladus orientalis, Pinus tabulae formis, Tamarix chinensis were measured with a portable LI-6200 gas analysis system under natural conditions in the mountains adjacent to Lanzhou City.

利用LI-6200便携式光合测定仪对兰州市南北两山侧柏、油松、柽柳等3种绿化树种在自然条件下的光合速率P(下标 n、蒸腾速率、气孔导度G(下标 s、光合有效辐射、空气相对湿度、大气温度和水分利用效率进行了测定。

The correlation analysis and stepwise regression between physiological characteristics of three species and environmental factors showed that the regression equation of Platycladus orientalis between photosynthetic rate, transpiration rate and the environment factor was P(subscript n=0.006PAR+1.176RH, E=1.120T; the regression equation of Pinus tabulae formis was P(subscript n=0.010PAR, E=1.004T+0.482RH; the regression equation of Tamarix chinensis was P(subscript n=0.015PAR, E=0.757T+0.566RH-8.397G.

对3种树的光合速率和蒸腾速率与影响因子进行相关分析及逐步回归分析表明，各树种光合速率和蒸腾速率的回归方程分别为，侧柏：P=0.006PAR+1.176RH，E=1.120T；油松：P=0.010PAR，E=1.004T+0.482RH；柽柳：P=0.015PAR，E=0.757T+0.566RH-8.397G。

Based on the analyse and discussion of temperature、degree of humidity、microorganism activity、and litterfall's characteristics,together with the analyse of putrefied degree experimentation of Tamarix branches and leaves,We found that amount of litterfall's decomposition was larger year by year during recent years,but in longer ago age, It presented a steady situation.

因此，在有限的观测和分析中，我们认为柽柳沙包层状结构可长久的保存下去，柽柳沙包年层可成为现代风沙作用强烈的荒漠地区恢复和重建古地理环境的重要手段。

Eustigmata tamaricina is only species of psyllids which could form galls on Tamarix in the north of Xingjiang, China.
