Pam treatment can prevent the disintegration of soil aggregates, even improve the structure of soils and prevent crust formation. pam, with high viscosity, can significantly increase water infiltration
Pam具有良好的黏結力，能有效改良土壤的表層結構，維護了土壤孔隙連通性，增加土壤的入滲率。 -
The research showed that pam could improve soil structure, and greatly increase the stabilization of soil aggregates, so soil crust development would be decreased. fifthly, soil grain that controls rainfall splash erosion was obtained, the influence of soil clay was very great during initial stages of rainfall. with rainfall going on, soil coarse sand and fine sand would control the splash erosion
五、控制土壤濺蝕的主要土壤粒級：在降雨初期土壤的的粘粒對濺蝕速率的影響較大，隨著降雨歷時的延長，土壤中的細砂和粗砂成為濺蝕速率影響較大的因子；六、對土壤濺蝕影響較大的土壤結構特徵因子：降雨5分鐘時，土壤的滲透系數對濺蝕速率的影響較大，隨著降雨的繼續進行，土壤的團聚度一直對土壤濺蝕速率影響較大。 -
Ploughing deeper and corn residues might promote formation of soil aggregated structure, decrease soil bulk density, relax solum, decrease soil porosity, raise soil permeability, improve soil structure and holding - water capability, create better soil biology condition for growth of crop, and coordinate water, fertilizer, air and heat etc. to prevent the fertility deterioration of the corn belt phaeozem and ameliorate soil, it is need to reform tillage and fertilizer application for the corn belt phaeozem in the central part of jilin
針對吉林玉米帶黑土土壤退化現象，從黑土玉米的耕作制和施肥制的改革入手，並結合農村現有機械和技術水平，採用玉米「輕主重輔」三三耕作制和玉米「一穩二減三補」施肥技術，提出吉林玉米帶黑土土壤調控技術體系。 -
The study of nt began in the 1950s in our country for high yield. the experiment indicated that long - term of nt could improve the soil ' s physical structure and the soil ' s sluice capacity, and could aggregate the accumulation of various nutrients in soil and increase plant yield
試驗發現：長期免耕，能改善土壤物理結構，增加土壤蓄水量、容重、土壤溫度和水穩性團聚體，有利於土壤中各種養分的積累，特別是有機質積累很快，出現上高下低的分層現象，並相應增加作物產量。 -
Based on above - mentioned analysis, the strategy and measures to prevent the soil fertility quality degradation of artificial picea mature forest and improve the stand ecological environment were put forward, including the rational management of inter - cutting down and fostering after artificial picea forest matured. because conifer - hardwood forests generally contain more tree species than pure coniferous forest, and their structure also is more complex, forestation in subalpine of western sichuan should be conifer - hardwood forests
林地土壤有機質主要來源於凋落物的分解，並受其分解速率的控制，解決當前人工成熟林地土壤退化的主要措施應為林地凋落物分解創造條件，即因地制宜地對成熟人工林進行間伐或輪伐，當前在該區域造林應避免營造針葉純林。 -
It was showed that forest with good structure could improve the soil noncapillary porosity and water conversation function, and it was implied that forest with rational structure stored rainfall and surface runoff quickly
表明具有良好結構的林分，可有效改善土壤非毛管孔隙度和滯留貯水功能，從而有效地提高對降雨的快速貯存以及蓄洪與涵養水源作用。 -
Because the right of development is basic one for mankind, so to clear away poverty is the first step. at the same time, we must improve the population ' s education, and only combination two aspects, the area can get rid of the poor situation and go on in a sound way ; to improve the traffic condition in order to increase quantity of substance, finance, information et al. ; to industrialize agriculture depending on the advantages of climatic resources ; to reform the traditional technology and develop infant industry, actively to form optimum industrial structure and increase the quality of production ; to pay more attention to environmental problems, especially harness and control industrial pollution, conserve natural resources and protect soil
首先是全區脫貧，並且與提高人口素質相結合，只有二者結合起來，才能真正實現脫貧治富：加強交通網路的建設，以提高區域內外物質、信息、資金和人員等的流通；在發展本區優勢作物的基礎上，實行農業產業化經營，以公司（企業）十農戶型模式和主導產業型模式發展新型農業；對傳統產業進行創新升級，繼續大力發展「糖、茶、電」 ，同時積極培育新興產業，搞好民族文化旅遊，以求提高全區產業的整體水平：重視生態環境問題，以工業污染的治理和農業水土流失防治為重點。 -
A good forest structure could improve the even degree and range of distribution obviously, and improve the porosity ; the fractal dimension ( fd ) and mean weight diameter ( mwd ) could sign the soil structure feature objectively
良好的林分結構能明顯提高土壤粒徑的分佈均勻程度與范圍，改善土壤孔隙狀況；分形維數和重量平均直徑能比較客觀地表徵土壤結構特徵，是較為理想的土壤結構測定指標。
