Determined by the specific geological background of Longhetun, the characteristics of the soil resources show abundant calcium and leaning to alkaline. Monomial indexes to evaluate the revisal coefficient of soil adapted to karst mountains areas were screened out combined with the function of karst dynamics system and analysis of characters of each factor about fertility in soil. Predigestion model to soil revisal coefficient monomial assessment was established by successful importation of the content of nutrition elements in plant body, latent efficient elements in soil and available thickness of soil in the cranny of epikarst according to the characters that three carriers of soil, soil water and karst water supply nutrition to plants and two layers of foundation consist of surface soil and soil in epikarst cranny, and several types of soil revisal coefficient and weather-soil productive potentiality were calculated, the results show that the soil revisal coefficient was even more practical after modification than before, which make up of innovation of this study.

龙何屯特殊的地质背景条件决定了耕地土壤资源的富钙偏碱的特点，结合岩溶动力系统的作用，系统分析土壤中各肥力因子的特点，筛选出适宜岩溶石山区特点的土壤订正系数评价单项指标，针对研究区存在土壤、土壤水、岩溶水三种载体提供植物营养和表层土、土下表层岩溶带裂隙土两层空间基质的特点，成功引入植物体内营养元素含量、土壤元素隐性有效态含量及土下表层岩溶带裂隙土有效厚度等新参数指标，探讨建立了土壤订正系数单项指标评价简化模型，计算出龙何屯各耕地类型土壤订正系数和气候-土地生产潜力，结果显示修正后的土壤订正系数比修正前更符合实际，成为本研究的创新点。

In the first sphere it is an implicitly universal, self-identical spiritual being; in the second it is explicitly for itself and has become inwardly divided against itself, sacrificing and abandoning itself; in the third, which as self-consciousness is Subject, it possesses directly in its own self the force of Fire.

同样，内在的本质，或者说，具有自我意识的现实中的简单精神，作为一个统一的世界，也分解为象自然所分解的那样一些普遍的、但具有精神的元素或质体：其中第一种是自在普遍的、自身等同的精神本质；第二种是自为存在着的、已变得自身不等同了的、正在自我牺牲和自我献身的本质；第三种，作为自我意识，是一种本身直接具有火的力量的主体。

The results indicate that the main lithology of the Yeniutan granite are granodi orite and adamellite, which are low in silicium, rich in aluminium, poor in alkali and rich in B, V, Zr, Ag, Pb, Zn, Cu, W, Be etc.
