Through this study, the sustainable management hierarchical system of forest ecosystem was established, providing the frame of forest sustainable management which given dominance to the basic hydrology ecosystem processing of mountain forest. At the same time, this research brought forward the "double-cycle" mode maintaining the integrality of Tianshan Mountain forest ecosystem. Within all these studies, on one hand, through the research about the regeneration response to different disturbance types, the scientific measures concerning restoration and rebuilding of fragmentized landscape were supplied. On the other hand, t

This change may brought tremendous benefits to the economy of zoology:① the forest land renew as elements of Kai county landscape, the cover ratio of forest increase obviously to 66.29% from 22.55% now, gain double. At the same time, the scale and intension of the soil erosion will control efficiently with the disappearances of the steep slope which use for furrowing; and it don't exist converse succession, it also make the whole landscape ecosystem system enter into virtuous circle.

这种变化将产生巨大的生态经济效益：①有林地重新恢复为开县景观的基质，森林覆盖率显著增加，将由目前的22.55%增至66.29%，净增2倍，同时，陡坡耕地全部消失，水土流失规模和强度将得到有效控制，现有不少嵌块体的逆向演替将不复存在，使整个景观生态系统进入良胜发展。

The results shown that both [Cu_2]~2+ and NR molecular can intercalates into the DNA double helix layer, and there is a competition between these two interactions. Furthermore, chemometrics approach, parallel factor analysis, was used to resolve the measured three-way CW-SFS data, which provided simultaneously the concentration information for the three reaction components, NR, [Cu_2]~2+ and NR-DNA, for the system at each equilibrium point. This PARAFAC analysis indicated that the intercalation of the [Cu_2]~2+ molecule into the DNA proceeds by exchanging with the NR probe, and can be attributed to two parallel reactions.
