The Difference of the Pulmonary-Artery Pressure of the Migrants from Difference Elevation at the 4636 - 4907 m Altitude

Study Objective： To compare and analyze the changes of the pulmonary-artery pressure of the migrants coming from different elevation in the hypoxic environment of 4636 - 4907 m extreme altitude. To explore the susceptibility to hypoxic pulmonary-artery hypertension （PH） in the subjects from different altitude and profession. Methods： By using Color Doppler Ultmsonography （CDU）, measuring the pulmonary-artery pressure of 207 healthy men, who had continuously being lived and worked at the extreme altitude for more than six months, and then were divided into three groups according to their profession and the altitude of original living place. Results： There was a significant difference in the outcomes of pulmonary-artery pressure from the 3 groups. Conclusions： Altitude of original living place, labor intensity are some of factors that impact the pulmonary-artery pressure of the people who exposure to a hypoxic environment. The pulmonary- artery pressure of person without strenuously physical work experience was more sensitive to hypoxic surroundings than that of labor workers. It was not always the fact at an extreme altitude that the moderate altitude mountaineers were superior to other migrants from a lower altitude or plain. The higher PH was found in the groups of the moderate altitude mountaineers and labor workers. It is unlikely certain that one with PH would surfer from HAPE.

Discovery of the granulite xenoliths in Cenozoic volcanic rocks from Hoh Xil,Tibetan plateau

Two-pyroxene granulite and clinopyroxene granulite xenoliths have been recently discovered in the Late Paleogene toNeogene volcanic rocks (with ages in the range of 4.27～44.60 Ma) that outcropped in Hoh Xil, central Tibetan plateau. Based on theelectron microprobe analysis data, the xenoliths provide constraints for the formation equilibrium temperatures of the two-pyroxene gran-ulite being about 783 to 818℃ as determined by two-pyroxene thermometry and the forming pressure of the clinopyroxene granulite beingabout 0.845 to 0.858 GPa that is equivalent to 27.9～28.3 km depth respectively. It indicates that these granulite xenoliths represent thesamples from the middle part of the thickened Tibetan crust. This discovery is important and significant to making further discussion onthe component and thermal regime of the deep crust of the Tibetan plateau.     

A Study on Forest Species Diversity and Its Ecological Service Function in the Plateau Area of Western Sichuan

This paper presents a study on species diversity and its ecological service function in the plateau area in western Sichuan. The results show that species diversity in the plantations on the cutover land has a tendency to increase and that its ecological service function is to be improved with stand age growing. The species diversity in forest communities is also gradually increased on different succession stage till reaching a climax level. But the species diversity in the climax community is slightly decreased before it reaches a relatively constant status. Ecological service function of diversity is gradually strengthened with the progress of succession. In addition, species diversity in a stand in a similar site and at a same age differs among forest types. Species diversity index within a coniferous and broad-leaved mixed forest is larger than that within a coniferous forest. Meanwhile, species diversity enriches as the tree density increases.

黄土塬区域城市地表水下渗问题研究

在大规模现场试验及分析基础上,研究了黄土塬区域城市地表水下渗能力、对工程地质及地下水污染的影响问题.结果表明,黄土对地表水有较强的下渗能力,采用0.3～0.5 m/d的稳渗率作为下渗工程设计参数是比较合理的.湿陷性黄土层厚达20 m左右,各类建筑与新建下渗水池之间的距离不得小于60 m.黄土塬地表水下渗的规律是以垂直裂隙下渗为主,水平方向下渗量很小,且为不均匀下渗.为保护地下水,雨水可以下渗,污水严禁下渗.为黄土塬区域城市水土保持提供了理论参考.
