鄂西重力地质灾害的研究

综观鄂西地区岩崩、滑坡、坍方和泥石流等地质灾害的成生，笔者认为大宇宙天体运动控制下的内动力和地质基础背景是其成生变形的主要因素，而与大宇宙天体运动有关的各种外动力条件的影响和变化及人类与生物对自然环境的影响和破坏，则是其成生发展的诱发因素。两种变量（即内、外动力）和天体运动的有机组合与变化趋势，使地质灾害成生的类型及其频度、强度、破坏（形变）特征及变形机制不尽相同，变形特征多样。在发生时间和灾害规模上多受天体运动变化规律所制约。据此可对地质灾害的预测、预报进行更深入地研究，并采取相应的防治措施。

A Study on the Gravitational Geological Hazards in Western Hubei

Based on a comprehensive survey on the generation of the geological hazards such as rock avalanche,landslide ,collepse and debris flow in the mountainous areas of western Hubei,the authors hold that the endodynamic force controlled by the motion of major cosmic celestial bodies and the geo-logical basic background are the principal factors for their generation and deformation,whereas the ef-fects and changes of various exodynamic conditions related to the motion of major cosmic celestial bod-ies as well as the influence on and damage of the physical environments by human beings and orgas-nims are inductive factors for their generation and development.The organic associations of the two variates with the motion of the celestial bodies and their variation trends lead to some differences in ge-netic types,frequency,intensity,damage(deformation)and deformation mechanism as well as di-versities of deformation features of geological hazards.The occurrence time and scale of the hazards are largely controlled by the variations in the motion of celestial bodies.In view of the above,a further study can be made to predict and forecast geological hazards and to take corresponding measures for their prevention and control.
