The spatial semi-variogram values of above-ground biomass of perennial herbs and Mesophytes, following the increase of spatial distances, showed decreasing trends when semi-variogram values exceeding the effective ranges. Howeve,semi-variogram values of above-ground biomass of other functional groups, following the increase of spatial distances, showed a trend of increasing spatial variability, but semi-variogram values were at unchanged value when exceeding the effective ranges.

On the other hand, a service provider may receive many requests at the same time, and because of the limited resources, it can't serve all of them. Consequently, for both service requesters and providers, there is a challenge of selecting interaction partners. This can be achieved by our proposed one-to-many service negotiation model.
在这个模型中,利用模糊命题表示协商参与者对服务的约束,这些约束是非数值化的;使用效用函数表示对数值化的服务非功能属性的偏好,采用二者相结合的方法建模对服务非功能属性的偏好选择。

Based on long-term monitoring convergence deformation of Wuqiaoling deep-buried long tunnel, this paper analyzes convergence deformation regularity of two parallel main tunnels. Results show the left main tunnel's convergence obviously exceeds that of the right, because the right main tunnel's construction absorbs the experience of the left main tunnel. Furthermore, authors research on rheology rule of Wuqiaoling tunnel by FLAC(superscript 3D). Numerical analysis result basically is consistent with actual measurement result. Finally, 6 principles to dispose soft wall rock rheology are presented.
