Based on this and considering: land use has contacts with soil nutrient; the development of ecology and agrology has already formed the inter-dynamic relation in the last few years, the author sprouted a new idea that the study on land use is carried out in another way. That is to say, land use patterns are designed combining land use modes, soil nutrient with other respects and according as landscape ecology in order to land sustainable use.

在此基础之上，并鉴于以下两点：土地利用与土壤养分有着密切的联系；近些年来，生态学和土壤学的发展已经形成了互动的关系，笔者提出一条新的思路：换个角度入手来合理配置土地利用，即将土地利用方式、土壤养分和其它方面结合起来，依据景观生态学原理，通过土地生态设计来寻求土地利用优化模式，保证土地利用的可持续性。

Then,the mechanisms of PAHs accumulation,transfer and biodegradation and its effecting factors were elucidated combining field survey and laboratory simulation methods and environmental geochemistry,agrology and biology subjects.

It is an item of newest scientific findings incorporating microbiolody , agrology , plant nutrition into an organic whole, mainly take many kinds of function type biological active funguses as the core , regard such organic matter as innoxious and treated beasts and birds excrement and urine , humic acid ,etc. as carriers, while cooperating with right amountly , micro- nutrition element, reach and improve the soil microorganism to trend towards the department, foster and apply fertilizer purpose of soil, fertilizer add nitrogen synergist and phosphorus , potassium chela mixture also, can apply fertilizer once only , does not need to topdress again in the whole breeding time.

是一项集微生物学、土壤学、植物营养学为一体的最新科研成果，主要是以多种功能型生物活性菌为主，以无害化处理后的畜禽粪便、腐殖酸等有机质为载体，配合适量中、微量营养元素，达到改良土壤微生物趋系，培肥土壤的目的，肥料中还添加氮肥增效剂和磷、钾螯合剂，可以做到一次性施肥，全生育期不需再追肥。

The study of soils is called pedology, Soil organisms participate in the formation of the habitat and constitute one of the five interactive factors in soil formation; the other four are climate, topography, parent material and time.

土壤的研究称为土壤学。土壤中的有机体参与了栖息地的形成，是土壤形成中构成五个相互作用的因素之一；其他四个是气候，地形，母质和时间。

With the guidance of foundation theory such as geotechnical engineering, garden vegetation, pedology, soil magnetism and environment engineering and the base of slope ecological protection, this paper studies ecological material protection techniques which is suitable for abrupt rock slope.
