Section 2 introduces the history of family elderly support, analyses the reasons of the existence of it, expatiates on the factors that weaken the function of it, such as modernization of agriculture, population aging, family miniaturization, urbanization etc. section 3 introduces the history of the social old-age insurance in Chinese rural areas, analyses its impendency from the aspects of social stabilization, the rights and interests of the peasants, rural employment. Section 4 is the most important part of the thesis. It first refers to foreign practical experiences on rural elderly security, then demonstrates the elderly support at home which combines family elderly support and social elderly support, especially analyses the public pension.

Hechi-Yishan fault zone is located in the north of Guizhong depression, which general strike is NW-EW and consists of a series of obduction fault. Generally, there are two main faults, the fault-fold belt about 5-20km is made of main faults, subsidiary faults and concomitant folds; The dip of main faults is N or S; It can be divided into four different structural sections along its strike (Hechi section, Yishan section, Liucheng section and Yingshan section). There are some differences among these sections in structure characteristic, such as fault structure, associated structure, fold association style, deformation of rock, and so on.
