We will investigate the actuality of stony deserts in Guizhou, and divide their types on the basis of their intensity, covering rate of soil and vegetation and amount of species, and stduy the influence factors of forming different stony desert types in more coercing, and explore the ratio of influence factors in the different stony desert areas and the evolutionary mechanism of different stony desert types. Finally,we will stduy the growing conditions and species of arboreous in different geology, land form,hydrology region for natural lithogenic forest and artificial forest, and the natural conditions for failing in many artificial forest,and the reconstruction mechanism in different stony desert type regions.

The representative families are Dryopteridaceae, Athyriaceae, Polypodiaceae, Thelypteridaceae, Selaginellaceae and Aspleniaceae. The main genera are Dryopteris, Selaginella, Asplenium, Arachniodes, Pteris, Allantodia and Plagiogyria. The top families' distribution types are cosmopolitan and pantropic ones, the main genera are pantropical ones, while species distribution type belong to the east Asia type and represents the feature of subtropics transition to warm temperated areatype. As for the order of closeness, the sequence of pteridophytes floristic relations between Songyang and the adjacent regions goes as Southwest China, South China, Central China, Japan, North China, Northwest China and Northeast China. The six upland pteridophytes next to Songyang can be put into the same natural flora because of its closest relationship. But compared with other 11 upland fern flora in China, fern in Songyang is not rich enough. There are 37 species endemic to China in Songyang.

MethodsNonheparinized autohemic blood of the rat was taken out from rat"s femoral artery and injected into its caudate nucleus immediately to establish a model of intracerebral hemorrhage.The changes of edema in the ipsilateral bassal ganglia , ipsilateral cortex, contralateral bassal ganglia and contralateral cortex were measured at 1,2,3,5 and 7 days respectively after intracerebral hemorrhage. The rat"s packed red blood cells, lysed red blood cells and hemoglobins at different concentrations were injected respectively into the rat"s caudate nucleus. The changes of edema in various regions of the brain at different time were measured as above. 5U thrombin was injected into the rat"s caudate nucleus and the changes of edema in various regions of the brain at different time were measured as above.

The result showed that toughness of coarse-grain zone in X70 grade steel pipe HAZ was weak.Coarse grain,granular bainite,high binate and other unbalance low temperature variation result in quantity increasing. In addition to,impact toughness of coarse grain zone decrease with the t8/5 increasing.
结果表明:粗晶区是X70级管线钢热影响区中韧性较差的区域,粗晶区韧性恶化主要是晶粒粗化以及粒状贝氏体、上贝氏体等非平衡低温转变产物数量增多造成的,且粗晶区的冲击韧性随着 t8/5 的增加而降低。
