Based on field survey located by GPS, it is obtained landslides＇ location and distribution information by the method of remote sensing in this paper. The vector data of environmental factors that breed and induce landslides such as the elevation, the slope, the vegetation cover, the lithology, the rainfall and so on are gained using GIS（geographical information system） techniques of spatial analysis. All the data obtained are managed through building landslide management system. At the same time, the system is made the platform to appraise the relationship between the distribution of landslides and the environmental factors. The results indicate： landslides take place relatively easily in the slope range between 10° and 25°; most landslides are in the mixed area of bush and grass with a coverage degree of from 20° to 65°; the distribution of landslides has a positive relationship with the distribution of annual rainfall. The risk degree of Panxi Area is zoned and mapped by the model of liner stack using GIS technique, and the result indicates： the place of high risk degree is the belt of Panzhihua-Miyi-Dechang-Mugu and southeast of Huili county and Huidong county,and area is about 512 707 hm^2.

An evaluation model divided landslide hazard degrees in Wanzhou District of Three Gorges Reservoir Area. The model was established by GIS techniques and took land use/cover, stratum characters, slope aspect, slope gradient, elevation difference and slope shape as evaluation factors. The data of land use/cover were obtained by remote sensing, and the weights of the factors mentioned above were established by the analytic hierarchy process （AHP）. The results indicate, low danger areas in the studied area account for 66.51%, and high danger areas and very high danger areas occupy 1/3 of the total area. The regions of high and very high danger are mainly located around the urban area of Wanzhou District and on the banks of the Yangtze River with a relatively large area, where collapse and landslide directly threats densely populated areas and Three Gorges Reservoir. Slope destabilization, if occurs, will bring huge loss to social economy. All research results are consistent with the actual conditions; therefore, they can be regarded as a useful basis for planning and constructing of the reservoir area.

系统划分大地构造相可以加深对大洋岩石圈和大陆岩石圈之间构造体制转换的认识,有助于开展成矿远景预测和资源潜力评价。根据河北省大地构造相的基本特征,将其划分为3个相系、5个大相、19个相,并进一步划分出亚相。探讨了大地构造相与成矿的关系,认为成矿作用是在一定的大地构造背景下发展演化的,并受到大地构造环境的制约。天山—兴蒙造山相系成矿主要与华力西期侵入岩有关,矿产主要为萤石,零星赋存铍矿、钨矿、铅锌矿;华北克拉通相系是重要的成矿相系,产有与条带状铁建造(banded iron formation,BIF)有关的铁矿床,与花岗-绿岩带有关的金矿床,与古岛弧亚相有关的沉积变质铁矿、滑石、菱镁矿、石墨等;东部造山-裂谷相系的成矿与火山岩相、沉积岩相、侵入岩相有关,以接触交代型铁(铜)矿、斑岩型铜钼矿和岩浆热液型金矿为主,另赋存有铅锌矿、锰银矿、煤矿等。研究可为分析区域成矿作用形成的大地构造环境及其演化过程提供成矿地质环境与构造演化阶段的背景资料,为成矿规律和矿产预测研究提供各类矿产预测类型的地质建造与成矿构造特点。

目的探讨凝血酶对骨髓基质干细胞功能的影响。方法小鼠骨髓基质干细胞取自于4周龄C57BL/6J小鼠双侧胫骨和股骨的新鲜骨髓,细胞增殖的检测采用5-溴-2-脱氧尿嘧啶嵌入测定试剂盒,细胞迁移的测定通过细胞计数法,细胞凋亡是根据4,6-二氨基-2-苯基吲哚所染细胞核形态的改变来辨认。结果凝血酶可以促进骨髓基质干细胞剂量依赖性的增殖、抑制细胞的凋亡,但不影响细胞的迁移。结论结果表明凝血酶对骨髓基质干细胞增殖和凋亡均有影响,这种影响可能有助于保障组织修复过程中所需的细胞的数量,这种功能可能是凝血酶在组织损伤修复过程中起保护作用。
