The result showed that the content of soil carbon indices on slope cropland were lower and increased dramatically in linear pattern after the cropland were abandoned for some time. 50 years after abandonment, OC, AOC and NAOC would increase by 169%, 144% and 210% respectively, compared to the slope cropland and would be 35 %, 39 % and 33 % respectively, of t he natural Chinese arborvitae stand. The carbon pool index and carbon pool management index would sharply increased by 169% and 117%, comapared to the slope cropland would increase by 35% and 42% respectively, compared to natural Chinese arborvitae stand.

结果表明：侵蚀环境的坡耕地土壤碳库各组分含量较低，土壤碳库处于高速低效率运转；撂荒后可以显著增加土壤碳库各组分含量，并随恢复年限呈显著线性关系，50 a时，TOC、LOC和NLOC分别较坡耕地增加169%、144%和201%，为侧柏林的35%、39%和33%；碳库指数和碳库管理指数较坡耕地明显增加，增幅分别达到169%和117%，仅为侧柏林的35%和42%。

With Zhifanggou watershed under typical erosion environment as study plot, the abandoned in different time as subjects, and slope cropland and natural Chinese arborvitae stand as CK, the substitution method of space for time was applied to analyze organic carbon, active organic carbon, non active organic carbon and evolvement of carbon pool management index in the period of ecological restoration.

：采用时空互代法，以典型侵蚀环境纸坊沟流域生态恢复过程中不同年限的撂荒地为研究对象，选取坡耕地和天然侧柏林为对照，分析了植被恢复过程中土壤有机碳、活性有机碳、非活性有机碳及碳库管理指数的演变特征。

By and large, research projects undertaken by the Group fall into three categories. The first is geotechnical properties and prevention of geological hazards, with the stress on researches on dynamic properties of marine soil, coast-beach erosion and seabed failure, sediment reformation by benthonic fauna, failure of submarine pipelines, environmental geotechnical techniques, etc. The second is research on pollution and treatment of water and soil, with the stress on researches on ecological effects of exploitation activities in the marine environment, treatment of beach sediment pollution, treatment techniques of sea organism pollution, groundwater PRB treatment technique development, etc. The third is exploration of underground environment and geophysical data processing techniques, with the stress on devising equipment for detecting underground pollution and geological hazards, environmental GIS (Geographical Information System) and related analysis software, etc.

In a recent study, the researchers found that prolonged consumption of sports drinks may be linked to a condition known as erosive tooth wear, in which acids eat away the tooth's smooth hard enamel coating and trickle into the bonelike material underneath, causing the tooth to soften and weaken.

研究人员发现长期饮用运动饮料会导致腐蚀性的牙磨损，因为一些酸类会侵蚀牙齿表面光滑而坚硬的釉外壳并渗入内部的牙骨质，从而导致软化衰弱。

The root biomass improved the soil infiltration rate and reduced runoff,the runoff and erosion amount of meadow brome decreased by 98.2%and 99.9% respectively,and the ability of water retention and soil-reinforcement of meadow brome was 5.2 and 1.5 times than that of corn.
