In order to solve the control of the degree of anti-occlusion of the roadside landscape of the expressway curve according to the drivers’ visual characteristics during high-speed driving, a dynamic space model of the visual process of curved highway roadside landscape was established, and the calculation equation of roadside landscape visual field was derived. The dynamic occlusion ratio was defined by space coordinates, and the judgment model was proposed for the de-occlusion of the roadside landscape visual field.

Affected by the small scale of forest farmers’ land and the imperfect development of the forest land transfer market, China’s forest rights mortgage loans have suffered from more serious credit rationing. The application of financial linkage theoretically has the effect of solving credit rationing. However, previous studies on financial linkages have focused on the field of credit lending, whereas the applied studies in the field of mortgage lending are mainly case studies on transaction models, and empirical tests on the application of financial linkages in mortgage lending are lacking.

In this paper, a GPU-accelerated Cholesky decomposition technique and a coupled anisotropic random field are suggested for use in the modeling of diversion tunnels. Combining the advantages of GPU and CPU processing with MATLAB programming control yields the most efficient method for creating large numerical model random fields. Based on the geological structural characteristics of red-bedded soft rocks in central Yunnan, anisotropic rock random fields and tunnel excavation with various rotation degrees are simulated.
