The paper fristly compared the fertile soil with the incinerated sterile soil on the number of micro-algae , soil pH value , soil organic matter soil available phosphorus and soil nitrogen.And then, the author put fertile soil, which included micro-algae, proportionally into sterile samples and cultivated them respectively under illumination condition (micro-algae can live and reproduce)and dark condition(micro-algae will die in some time).The above indices were measured in 0, 30, 60 and 90days respectively, The analyse of the interrelation between the change of micro-algae"s number and the changes of soil pH value, soil organic matter, soil available phosphorus and soil nitrogen indicated:Soil micro-algae which were native to fertile soil conld adapt to the changed circumstance and light acted as a decisive role to the distribution of soil micro-algae.Under dark condition,the micro-algae"s number declined gradually and went to zero in the end,while under illumination condition ,on the 90th day, the micro-algaes number of per gramme was 6-7 times more than that of the beginning.

By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.

利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量，得出：天然灌木林地，受人为影响较小，每年有大量有机物质返还土壤，且天然灌木的根系可以很好的改良土壤的物理性质，同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分，土壤质量最好；农田受到的人为影响最大，但农田综合得分却好于人工柽柳芦苇地综合得分，这可能是由于在开垦初期的绿洲农田，受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致；乔木林地，由于人们用大水漫灌的方式灌溉，致使林地土壤变得板结，土壤物理性质下降，加上克拉玛依地区气候干燥少雨，一次灌溉后较长时间后才有下一次灌溉，致使土壤理化性质恶化，土壤质量不高。

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.

Statistic analysis showed that soil temperature as the driving factor to the diurnal variation of soil respiration. Soil temperature and soil moisture were the dominant environmental factors affecting the seasonal variation of soil respiration and explained 87% of its variability. LAI and root biomass were positively related to soil respiration rate, indicating that biotic factors also affected the seasonal variation of soil respiration. However, soil properties such as soil organic content, total nitrogen content, and C/N ratio had poor correlations with soil respiration. Top-dressing nitrogen fertilizer increased soil respiration significantly.
