土壤学

It is worth noting that Russia's land is very fertile, as the founder of the Russian agrology Dokukin恰耶夫pointed out, the black soil zone is Russia's main source of wealth, Russia's black earth has lost 20%-50% of humus, However, it is still the world's most fertile soil.

值得注意的是，俄罗斯的土地非常肥沃，正如俄罗斯土壤学奠基人多库恰耶夫指出的那样，黑土地带是俄罗斯的主要财富，俄罗斯的黑土地曾丢失了20%-50%的腐殖质，但仍是世界上最肥沃的土壤。

In the explore in water seepage mechanism of highway engineering, at the foundation of author's and other people's research, the author study the groundwater seepage and infiltration of rain and water with the groundwater dynamics, the rock mechanics ,the soil mechanics, the hydrologic geology, the engineering geology, the agrology. With the research result of the water seepage mechanism of highway, the author also study the principle design of waterproof, drainage and water environmental protection. The author's work is as follows:(1) The water circulation, the groundwater type and conversion, the equilibrium and circulation in soil water are introduced and studied; The seepage characteristics of rock and soil in response to stress are analyzed and studied.

作为在"公路工程地质环境中水渗流机制问题研究"中的探索研究，在本人科研和前人研究工作的基础上，以地下水动力学、岩土力学、水文地质学、工程地质学、土壤学为基础，研究公路工程建设对地下水渗流和雨水入渗的影响，以及公路防排水和水环境保护设计的原则方法，具体开展了如下研究工作：(1)首先对水循环、地下水类型及转化、土壤水平衡与循环进行了研究和介绍；分析研究了应力对岩土体渗流特性产生影响的机理。

Therefore, the soil Ni activity should be more concerned for the environmental soil science development, and the environmental management.

因此，土壤Ni的活性比之其全量是人们更应关注的问题，是环境土壤学应该研究的问题，也是环保管理系统中应该明确的问题。
