ANSYS analysis of structure transform node of Hongzhou pagoda;

The Kalpintag nappe is located at the southwestern foot of the Tianshan Mountains,consisting of several rows of NE-to EW-trending fold-reverse fault zones.

Based on a lot of outcrop geological surveys, we discussed the thrust fault belt in the front of the east section of Kalpintag in Kalpin area and found many evidences, including the fault incising the surface of diluvium and fluvial channel sediments and terraces, and also the fracture and subsection character of the faults.

This paper tries to discuss paleoearthuakes along the east section of the range front fault of Kalpintag during late Quaternary by doing field investigation along the fault, measuring geomorphic deformation and excavating trenches in some important sites where young alluvial fans were displaced obviously.

The Study on Geographical Hazard Evaluation of Baota District in Yan an City;

Based on field investigation and analyzing the material of Baota district, the theories of eco environmental planning is applied to evaluate the eco environmental features of this area, which is divided into five grades.

In order to dynamically monitor soil erosion and determine the relationship between landuse and soil erosion in Baota District of Yan an City,an analysis was performed using the data from TM images in the two periods of 1997 and 2004.
