生物风化

这表明生物风化最适宜的条件是湿热气候。

This suggests that the optimum for biological weathering would be in a hot , most climate .

研究结果表明，全新世早期气候温和干燥，沙尘暴明显减弱，风尘堆积速率降低，具有轻微生物风化成壤作用；

The results show that dust deposition was reduced because of the climate warming , and the biological weathering is beginning in the early stage of the Holocene .

生物风化作用研究进展

Recent development in bio-weathering research

认为全新世早期气候较温和干燥，风尘堆积速率降低，有一定生物风化成壤作用，土壤发育表现为边沉积边成壤；

In the early stage of the Holocene , dust deposition was reduced because of the climatic warming , and the biological weathering was beginning .

研究生物风化作用机理及在生物作用下矿物的演化序列，对于揭示土壤形成、化学元素循环规律、全球环境变化有着极其重要的意义。

Therefore , studies on the mechanism of bio-weathering and the corresponding evolution sequence of mineral will help us in understanding the formation of soil , the environmental cycle of elements , and the global environmental changes .

可是，在气候、地形、地貌、生物等风化作用影响下形成的花岗岩风化壳物理、力学强度差异很大。

The strength varies to a large extent in different regions and location of profiles due to weathering grades are influenced by climate , landform , biology , etc.

生物无时无刻不参与地球表层矿物和岩石的风化，但以往的研究大多注重物理风化与化学风化作用，对生物风化作用关注很少。

Although organisms always participate in the weathering of mineral and rock on the earth surface , much attention was paid to the physical and chemical processes , but little attention to the biological process in previous studies of weathering .
