It will have minimum drilling resistance torque and efficiency tree planting when the auger bit with 300 to 400rpm rotation speed and 0.047m/s feeding speed.

在钻头转速为300~400rpm范围时，进给速度为0.047m/s具有最小的钻孔阻力矩和最好的综合钻孔造林效率。

Fire resistance of Pinus armandii bole were tested with fuel bed designed by the authors during the prohibitive period of forest fire. The mortality rate was accounted with a program developed by the authors with Visual Basic 6.0 after the phloem of samples were soaked with 4% 2, 3, 5-triphenyltetrazolium chloride solutions, then painted and scanned the distributing map of mortal and living phloem, purified the map color with Photoshop. Relationships between fire resistance of the bole and diameter, wood bark thickness, temperature, and heating time were anayzed. Countermeasures of forest fire protection were put forward.

在森林防火戒严期，用自行设计的装置对云南主要造林树种华山松进行了不同温度、时间作用下的树干耐火性试验，用红四氮唑对高温作用后的树干韧皮部进行了染色，经勾绘、扫描后用Photoshop软件将死亡的韧皮部处理成易于计算机识别的纯色，用Visual Basic 6.0编写的程序计算了树干韧皮部的死亡率，初步分析了华山松树干耐火性率与树干直径、树皮厚度、受热温度、受热时间的关系，据此提出了相应的森林消防措施。

Under the current situation, it is of great practical significance to study focusedly on the functions of evergreen broad-leaved species and dynamic characteristics of community during the process of vegetation restoration.

因此，围绕常绿阔叶林造林树种的功能和植被恢复过程中群落功能的动态变化特征等方面的研究具有十分重要的理论和实践意义。

The test also shows that torque has not big change by using difference augers'tip and different angle of soil cutting blade on the end of auger's spiral wing.

不同钻头钻尖结构，不同切刀刃角在3种典型造林地的试验表明，这些因素对钻孔阻力矩的影响很小。

For example, relation of sand soil water content and plant leaf water potential of shrub breeding or arbor breeding in the morning can be simulated using the followed exponential function:〓 or 〓, in which, coefficient value of a and b are different on different breedings or different field.

通过在毛乌素沙地、乌兰布和沙地、库布齐沙漠、巴丹吉林沙漠等近6年的测试资料的研究分析表明：①营造固沙林后，沙土中的含水率降低，降低的程度主要受到林分密度和造林后林木生长年限的影响。

Casuarina trees were planted as windbreak belts along the perimeters of the Taichung Harbor for thirty years. Due to the harsh local environments and strong typhoon attacked in recent years, numerous Casuarina trees have died. As a result, various canopy gaps in the intended windbreak belt have been created.
