The Tianshan Mountains is a high and huge mountain body lying across the central part of xinjiang, china, and is also the main area where the runoff forms in xinjiang. In this paper, a set of RS-based study methods is put forward for deriving the information about the natural change of the ecology in arid areas, and the relationship between the climate change trend and the corresponding ecological response on the northern slope of the Tianshan Mountains since recent 40 years is analyzed from the scales of the land cover ecosystems and landscapes based on the observed data of climate, hydrology, modern glaciers and lakes on the northern slopes of the Tianshan Mountains since recent 40 years and the satellite RS data since recent 10 years by using the RS and GIS technologies. The results are as follows: (1) The overall trend of climate change on the northern slope of the Tianshan Mountains since recent 40 years is that both air temperature and precipitation are increased, especially the increase amplitudes of air tempera-ture, precipitation and annual runoff volume are high since the decade of the 1990s; (2) the in-tegrated indexes of the vegetation in all the geographical divisions on the northern slope of the Tianshan Mountains are obviously increased since recent 10 years, especially in the artificial oases and the foothill belts, such a change trend is advantageous for improving the vegetation ecology; and (3. the vegetation ecology in the arid areas is extremely sensitive to the climate change, the vegetation coverage and the biomass on the northern slope of the Tianshan Moun-tains are continuously increased because of the climate change since recent 10 years, their in-crease amplitudes in the plains and during the late stage are obviously higher than that in the mountainous regions and during the early stage.

Based on the analyses of hydrocarbon inclu-sions, K-Ar dating of authigenic illites and oil/gas-watercontact retrospection as well as other methods, the marineprimary reservoirs in the cratonic region of the Tarim Basinare found to have been formed in the late Caledonian toearly Hercynian, late Hercynian, and Himalayan, and oil andgas adjusted and redistributed in the Yanshanian (Jurassic toCretaceous) and Himalayan (Tertiary). The analyses alsoshow that the remaining primary oil accumulations aremostly formed in the late Hercynian, and the secondary oilreservoirs resulted from the adjustment and redistribution ofthe earlier accumulations during the Yanshanian and Hima-layan (especially late Himalayan), of which the Himalayan isalso the major stage of gas accumulation. The primary oilreservoirs formed in the late Hercynian mostly occur withinthe Paleozoic formation, whereas the secondary reservoirsformed in the Himalayan in the Mesozoic. The late adjust-ment and redistribution of reservoirs in the craton region ofthe Tarim Basin is ubiquitous because of the intensified tec-tonic movements since the Mesozoic, especially Cenozoic andintrusion of the high- to over-mature gas. Furthermore, thelower amplitude of reservoirs in the craton region also makesthem easier to be adjusted and redistributed. Therefore, theremaining paleo-uplift and palaeo-slope developed in rela-tively stable tectonic regions are the main potential areas forthe middle-large marine reservoirs in the Tarim Basin.

The local electronic structure and magnetic properties of GaAs doped with 3. transition metal (Sc, Ti, V, Cr, Mn, Fe, Co, Ni) were studied by using discrete variational method (DVM) based on density functional theory. The calculated result indicated that the magnetic moment of transition metal increases first and then decreases, and reaches the maximum value when Mn is doped into GaAs. In the case of Mn concentration of 1.4%, the magnetic moment of Mn is in good agreement with the experimental result. The coupling between impure atoms in the system with two impure atoms was found to have obvious variation. For different transition metal, the coupling between the impure atom and the nearest neighbor As also has different variation.

The causes of the disappearance of the ancient town of Loulan in xinjiang, china have been generally agreed to derive from two factors: human activities and natural factors (environmental variations). In this paper, the Muzart Glacier was selected as an example, and found that the length of the glacier has been gradually decreasing and the snow line has been retreating to a higher altitude, both results contributing to a decrease in river flow below the Muzart Glacier. From the distribution of moraines in the Tianshan Mountains and adjacent areas in different periods, the paper speculates that there have been four minor glacial periods since the Quaternary. Although the durations and scales of the four minor glacial periods were different, they all indirectly influenced the formation and disappearance of the Lop Nur Lake. The events of the fourth minor glacial period are the important impact factors in the existence and disappearance of Loulan. Whether the disappearance of Loulan can be related to the events of the three previous minor glacial periods needs further investigation.

In the four decades from 1951 to 1990, the six provinces or autonomous regions (xinjiang, Gansu, Qinghai, Ningxia, Xizang and Nei Monggol) reported a total of 26 065surgical cases of hydatid disease, most of which were reported in the recent decade. About one third of the patients was children and adolescents under 15 years old. So far, cystic hydatid infections of local origin have been confirmed in 22 provinces, autonomous regions and municipalities in the whole nation. Findings of X-ray examination and real-time B-mode ultrasonography in agricultural and pastoral areas of xinjiang, Gansu, Qinghai,Ningxia and Xizang showed that the morbidity rate of hydatidosis in human population varied between 0.5% and 4.5%. The main animal intermediate host in all these regions is sheep, the morbidity of which varied between 3.3. and 90%. The infection rate of adult Echinococcus granulosus in dogs varied between 7% and 71%. The high-risk period for humans contracting hydatid disease is the pre-school age. Direct contact of children with dogs and ingestion of water, vegetables and foods contaminated by worm eggs are the chief mode of transmission for human hydatidosis. The common practices of home slaughter and of feeding dogs on offal containing hydatid cysts facilitate the life cycIe of the *** the basis of hydatid control efforts for several years, the Ministry of Public Health promulgated officially the '1992-1995 National Programme for Hydatid Disease Control'in April, 1992, and pilot studies in which the control of hydatidosis is composed of extensive health education, sanitation of slaughtering and management and deworming of dogs are being *** echinococcosis has wide distribution in china and is a major public health problem in hyperendemic areas, poses a great threat against people's health and influences the development of livestock husbandry.

FTIR spectra of inclusions sampled from fault-zone reservoirs of the northwestern Junggar Basin show that water, with different abundances, does exist in petroleum inclusions. It is thus implied that petroleum inclusions can seldom form without water. Different inclusions hosted in one single grain, and formed in one oil charging phase, have a largely varied ratio of water to oil and slightly changed CH3.CH2 ratio. This likely provides evidence for fault-related episodic migration and accumulation of hydrocarbons.
