As a case of demonstration section of ecological reconstruction in Guohua, Pingguo County in Guangxi, photosynthesis potentiality model, revisal coefficient model of temperature, moisture and soil amongst existing models are amended and validated to evaluate productive potentiality by utilization of mechanism methods on the foundation of detailed analysis of specific entironmnet condition, respectively.

本文以广西平果县果化镇生态重建示范区为例，在充分分析研究区特殊的生态环境条件的基础上，选择机制法评价土地资源生产潜力的建模思想。

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。

His own place lay in a rougher territory, where there was some clay in the soil and it was not so productive.

Soil erosion by wind, as a natural disaster haunts on dry lands, not only degrades soil productivity but also often results in dust blizzard weather. It may cause pollutions of air and water, damages of highway and railway, wear and tear of buildings and machinery and harmfulness in health of people and animals. Therefore, to combat wind erosion means improving the environment for people to live and work, means heightening the living standard of the local people, and means promoting productive forces. But China has a vast land where probably occur wind erosion disasters, the arid, semiarid and subhumid areas of the temperate zone all are potentially hit by wind erosion. To control wind erosion in China is a very arduous task. More difficult is to achieve recognizable effectiveness with lowest cost.
