查询词典 shrub steppe

I have calculated the species diversity for 3 layers (i.e. tree layer, shrub layer and herb layer) by means of various biodiversity index formulas and analyzed the relative species abundance using 9 models of the probability density distribution functions, such as, 3 Distribution (or Beta Distribution, Weibull Distribution, Lognormal Distribution, Poisson Distribution, Binomial Distribution, Negative Binomial Distribution ,Geometric Distribution, etc.. chi-square analyses were conducted on species distribution by using the chi-square test formulated by Pearson to test which distribution function is better, the result of chi square test made it possible to reject the other 8 distribution functions, theβdistribution function performs better than other probability density functions, it has a very close approximation, which can be used for the description of relative abundances of species in forest communities in this data set.

在相对多度研究上选用了九种概率分布模型，这九种概率密度分布函数依次为：贝塔分布、Weibull分布、对数正态分布、泊松分布、二项分布、负二项分布、几何分布、对数分布和奈曼A型分布，并进行了严格的卡方检验，结果表明：其它八种分布均被遭到拒绝，只有贝塔分布获得了通过，且拟合的结果非常理想。

The study indicated that Choerospondias axillaries cropped with peanut wasn't optimum agroforestry model and it couldn't be extended blindly in subtropical China, that N〓-fixing shrub should be chosen to intercropped in farmland rather than tree, and that shade tolerance plant should be chosen to intercropped in orchard garden or man-made forest rather than photophilous plant in alley cropping system.

总之，花生南酸枣间作不是低丘红壤地区优化农林间作模式，不适宜盲目发展。在红壤农田系统中实行农林间作应优先选择固氮灌木，而非高大的乔木；在果园或人工林系统中实行农林间作应优先选择耐荫植物，而非花生等喜光作物。

Small shrub of southern and western Australia having pinkish to rosy purple tubular flowers.

澳大利亚西部和南部的小灌木，有略带桃色到玫瑰紫色的管状的花。

One would approach at first warily through the shrub oaks, running over the snow-crust by fits and starts like a leaf blown by the wind, now a few paces this way, with wonderful speed and waste of energy, making inconceivable haste with his "trotters," as if it were for a wager,and now as many paces that way, but never getting on more than half a rod at a time; and then suddenly pausing with a ludicrous expression and a gratuitous somerset, as if all the eyes in the universe were eyed on him —— for all the motions of a squirrel, even in the most solitary recesses of the forest, imply spectators as much as those of a dancing girl —— wasting more time in delay and circumspection than would have sufficed to walk the whole distance—— I never saw one walk —— and then suddenly, before you could say Jack Robinson, he would be in the top of a young pitch pine, winding up his clock and chiding all imaginary spectators, soliloquizing and talking to all the universe at the same time —— for no reason that I could ever detect, or he himself was aware of, I suspect.

有一只赤松鼠开始谨慎地穿过矮橡树丛，跑跑停停地在雪地奔驰，像一张叶子给风的溜溜地吹了过来；一忽儿它向这个方向跑了几步，速度惊人，精力也消耗得过了份，它用"跑步"的姿态急跑，快得不可想象，似乎它是来作孤注一掷的，一忽儿它向那个方向也跑那么几步，但每一次总不超出半杆之遥；于是突然间做了一个滑稽的表情停了步，无缘无故地翻一个觔斗，仿佛全宇宙的眼睛都在看着它，——因为一只松鼠的行动，即使在森林最深最寂寞的地方，也好像舞女一样，似乎总是有观众在场的，——它在拖宕，兜圈子中，浪费了更多的时间，如果直线进行，早毕全程，——我却从没有看见过一只松鼠能泰然步行过，——然后，突然，刹那之间，它已经在一个小苍松的顶上，开足了它的发条，责骂一切假想中的观众，又像是在独白，同时又像是在向全宇宙说话，一我丝毫猜不出这是什么理由，我想，它自己也未必说得出理由来。
