Based on the variation tendency of grassland productivity, this article describes the present situation of the grassland degeneration in inner mongolia,. With its emphasis on two main meteorological factors (precipitation and air temperature), this article analyzes the characteristics of climatic changes in the inner mongolia prairie in 30 years (1970～1999) and discusses the effect of climatic factors on grassland degeneration. At the same time, this article analyzes the causes for the deterioration of grassland ecological environment from such aspects as the material flow balance within the grassland ecosystem and the effect of human activities on grassland ecosystem. The analysis shows: from the present meteorological data and grassland monitoring data, it is hard to conclude that the grassland climate is getting drier and drier and proceeds to cause the deterioration of the grassland ecosystem; animal husbandry is the main type of land use in this area, the vegetations within the ecosystem are mainly controlled by domestic animals, and the main causes for the rapid deterioration of grassland ecosystem are the malajustment of input and output of material flow (take N for example) and the seasonal imbalance of supply and demand between the grass and the domestic animals; while the climatic changes only make the deterioration of the ecosystem more serious. This article proposes that the effective measures to harness and maintain the grassland ecosystem health in this area are to increase the material input within the ecosystem, to adjust the nature production mode of grazing all through the four seasons, and to actively introduce new seeds into animal husbandry to alleviate the grazing pressure on the grassland during the sensitive spring period, etc..

Hetao irrigation region is situated in the western part of inner mongolia. It stands bythe Yin·Shan mountain in the north, leans against the Yellow River in the south, nears theeastern side of Ulanbuhe Desert in the west and borders on Baotou in the east. It is 280kilometers in length from east to west. and 45-90 kilometers in width from north to south.

The Middle Proterozoic Chartai Group separated by two unconformities consists of three depositional se-quences: the Shujigou Formation-Zenglongchang Formation (DS Ⅰ), the Agulugou Formation (DS Ⅱ), andthe Liuhongwan Formation (DS Ⅲ). The carbonate platform and back-platform basin are the basic environ-ment model of the Chartai Group. The syndepositional faults on the oceanward side of the carbonate platformand large-scale slumping in the soft sediments are important marks of facies tracts. The newly establishedZenglongchan uplifting, an epeirogenetic uplifting, plays an important role in the formation of thepalaeogeographic framework of the Chartai Group. The stratigraphic correlation between the Chartai Groupand the Bayan Obo Group is made for the first time by using sequence stratigraphic principle and model estab-lished by P.R. Vail. The Chartai Group, which was deposited on the northern passive continental margin of theNorth China platfom, represents the platform cover.

It is revealed that the protolith of gray-light brown potash-feldspar-leucogranulites and granulites in the 2nd formation of the LG in Tanyaokou deposit are quartz kerotophyre of synsedimentary eruption based on the following facts and features: (1) The rocks look compact and homogeneous without obvious crystals with naked eyes; (2) they contain blastoporphyritic or glomeroporphyritic and blasto-crystalloclastic crystals consisting of quartz with wavy extinction and albite with obvious alteration and deformation; (3) they also contain radiated and fibrous blasto-microspherulitic texture and swallow-tailed bifurcate and blasto-hollow-skeleton crystal texture, representing the rapid cooling characteristic of the magma during submarine volcanic eruption; (4) the major chemical compositions of the rocks are: SiO2 = 70.80%―76.00%, K2O (4.83%―6.22%)>Na2O(2.78%―3.80%), and K2O+Na2O = 8.63%―9.00%; and (5) their petro-chemical diagrams indicate that they are volcanic rocks. Together with the characteristic that they occur in the same sequence with potassic spilite (SiO2 = 46.12%―50.68%, K2O = 4.23%―5.93%>Na2O = 2.15%―3.14%, K2O+Na2O = 6.51%―8.08%), it can be confirmed that the vol-canics occurring in the 2nd Formation of the LG in Tanyaokou district are double-peaking potas-sic volcanic rocks. The discovery, together with the tuffs with ore minerals and the distribution of lead isotopic as well as the value of Co/Ni of pyrites >1 showing the obvious endogenic metali-zation, can prove that the Tanyaokou deposit is an untypical SEDEX-type deposit formed in the extension fault basin in the Mesoproterozonic aulacogen of the northern margin of the North China Platform, and its metallogenesis is related to the synsedimentary volcanic activities and the hydrothermal exhalation, and both the ore-forming material source and volcanics came from mantle or lower crust. These facts mentioned above, together with the meta-volcanic rocks (double-peaking) found in the Dongshengmiao and Huog

The authors have done some researches on the leaves and stems of potamogeton L. in inner mongolia by comparative classification by using the methods of morphology and anatomy. After having studied we found that they are ten species in inner mongolia. Among them, five species are belonged to cosmopolitans P. perfoliatus L., P. crispus L., P. pectinatus L., P. panormitanus Biv. and P. lucens L.; two eastern Asian sppcies: P. distinctus A. Benn. ao(?) P. malaianus Miq.; P. vaseyi Robbins is an East Asian-North American species) P. zosterifolius Schum. is an Eurasian species; one new species, P. acifolius Ma, is endemic to lnner mongolia.

Dynamic analysis of Sand Source in west Inner Mongolia

第三届国际沙尘暴与降尘天气专题学术研讨会

作者： Zhang Tao (forestry college of inner mongolia agriculture university 010018 Hohhot China)

＜正＞ The sand source is one of the main factors that related to the sandstorm. The data of RS TM in 1990s and ETM in 2002 are analyzed by the software of PCI, ARCGIS, ARCINFO, which is based on synthesizing and comparing wave band. Typical windblown sand areas are analyzed in the west of inner mongolia, such as Wulanbuhe desert, Kubuqi desert, Maowusu sand, Tenggeli desert. West of inner mongolia ecologic system in sand source is destroyed seriously because of population increasing, developing of industry, agriculture and animal husbandry, mineral in recent 10 years. Climate condition is extremity rigor in this area. That cause sandstorm takes place frequently. The orientation of sand source is tend toward to the southeast.
