Antarctic environment has valuable baseline information for understanding the global change. The objectives of this study were to investigate the impacts of human activities on Antarctic terrestrial ecosystem. Based on the investigation results and the sampling analysis of the environment of Fildes Peninsula, King George Island, Antarctica, it was shown that there are some artificial radioactive elements—? ? 137 Cs in Antarctic environment: the radioactivity of 137 Cs in the surface soil, the surface moss, the fruticose lichen and the crustaceous lichen are 6 00—14 80, 25 07, 29 04 and 58 07 Bq/kg separately; i.e. the sequence of 137 Cs specific activity is as follows: crustaceous lichen>fruticose lichen>surface moss>surface soil, which demonstrates that the crustaceous lichen is one of the most sensitive monitor ways for the effect of the long term diffusion of 137 Cs. The impacts of the scientific research activities on the partial ecosystem of Fildes Peninsula include: the changes of the landscape and the soil material have made a strong freezing thawing process, which decreases the stability of the ground surface, causes the degradation of the vegetation in the some small areas; some small lakes, runoff and lichens in middle areas of Fildes Peninsula have been affected by the wastes of the stations, in the surrounding areas of the expedition stations, the concentration of Cr, Cu, Ni, Pb and Zn in the lichen and the water are higher than that of the contrasting area. Fildes Peninsula is one of the most crowded areas of expedition stations, at some extent, the environment and terrestrial ecosystem have been affected by the human activities. The conservation of the environment and ecosystem should be an important aspect of Antarctic environmental sciences.

The results from investigations indicated that mercury pollution in terrestrial ecosystem was serious due to the anthropogenic mercury emission growing in Chongqing, China. The concentration of atmospheric mercury in Chongqing was 34.4±2.7 ng/m\+3 with the range of 9.2—101.5. The accumulation of mercury in surface soil was increasing with time. The mercury content of some agricultural products have exceeded the food health standard value, especially near the mercury emission sources. The mercury accumulation in soil plant system was affected by atmospheric mercury and a positive correlation between them was found. Volatilization of mercury was the most important processes with which soil mercury joined the global mercury recycling.

The fate of BHC in the terrestrial ecosystem was investigated under both laboratory and field conditions. The uptake, accumulation and degradation of BHC in earthworms and corn plants were studied. Earthworms could absorb and accumulate BHC residues from soil. Statistically, significant correlation existed between the amounts of BHC in soil and in earthworms. Different species of earthworms appeared to concentrate BHC in their bodies to different extents. In a terrestrial ecosystem, the uptake, accumulation of BHC residues by soil animals and plants had an effect on each other.

The radioactive isotope 137 Cs is one of the important tracers for studying the physical processes and the human impacts on the environment. Based on the investigation results of the terrestrial ecosystem of Great Wall Station, Antarctica, it was shown that there are some artificial radioactive elements 137 Cs in Antarctic terrestrial ecosystem. The sequence of 137 Cs specific activities is as follows: crustaceous lichen>fruticose lichen>surfacemoss>surface soil, and the crustaceous lichen is one of the most sensitive ways in monitoring the impact of the longterm diffusion of 137 Cs on the environment.

This paper studies the effects of land cover changes on distributions andcirculations of nutrients in a terrestrial ecosystem, taking Jianou Niukenglong Grassland ecosystemExperimental Station as a case study. During a two year experiment from 1994 to 1996, the land covertypes were changed from desert slopeland to grasslands, in particular, Chamaecristarotundifolia(pers) green + Pasdum thunbergii and Glycine max var. + Pasalum thunbergii. In order tostudy land cover change effects on nutrients in the terrestrial ecosystem, we selected organicmaterials (OMs), nitrogen (N), phosphorus (P), potassium (K) and aluminum (Al) to study theirchanges in total soil nutrient concentrations, nutrient reserves in soil, distributions andreservations of nutrients in distinct grassland communities and overall nutrient contents reservedin terrestrial ecosystem, and their circulation with land cover change. The experimental resultsindicate that with the increase of vegetation coverage, the total concentrations of N, P and K growrapidly in the soil, but that of Al decreases markedly. The increases of the total concentrations ofN, P and K were mainly the consequences of changes of the factors that affect soil evolution, e.g.,soil moisture, and changes of soil evolution processes, e.g., weathering rate and the decrease ofsoil erosion. These changes were caused by land coverage growth from desert slopeland to *** the change of the land cover types and the increase of land coverage, the activity of Alaccelerated as well, and the vertical penetration and lateral penetration of Al have been ***, the loss of Al within the experimental terrestrial ecosystem was inevitable, and thetotal concentration and reserve of Al in soil have become smaller and smaller, in spite of thegrowth of grass absorbing some amounts of Al. The Al reserve has increased in vegetation, but it hasdeclined in total terrestrial ecosystem. Land cover change also affects the circulations ofnutrien
