Application Of Sensitive Factors Appraisal Method In Geological Calamity Distribution In Jiaocheng District Ningde City Fujian Provice

The prediction of slop stability in space is a important content in environment geology or calamity Geology, and also is a proposition that many scholars devote to discussing in updays.with the succussive embedded study and extensive application of computer technology, geological calaming distriction menthods have developped from traditional qualitative appraisal to qualitative appraise combinate with half-quanlitative or quantitative appraisal. And have many mothods, the main methods is (1)appraisal of information quantiy. classity the influencial factors of instability of geological calamity, that is, reflect with the information that have the similar geological structure , geometry factor and impelling geological calamity factors and so on muli-geological factors and outer power factors. (2) System theory and its analyse method. Analyse system and appraise synthetically taking engineering geological environment of study region as a opening and dynamic whole . (3) Appraise analysis method of indistinct mathematics . Selecting qualitative or quantitative targets that are sensitive to a certain region , appraisal synthetically with the method of indistinct mathematics . these methods have the shortages that can't combinate organically the change of national factors with human engineering activities ,for example ,building house, embellishing road, making bridge and so on have maken great inflence to geological environment around . It has the very close contact between guide of geological calamity and human engineering activties .So , it can consider fully the influence that human engineering activities make to geological environment factor during the course of appraisal and analysis of geological calamity distriction .During the cotradiction of human activities and geological calamity , grasp the main direction --- sensitive factor , and so solve geological calamity more effectively and economically.On the basic of geological calamity investigation in JIAOCHENG region , NINGDE city, analyzing the dominate factors of geological calamity , build sensitive factors module . With appraisal analysis method of indistinct mathematics, district geological calamity in JIAOCHENG region , NINGDE city, and pose protection and regulation policy of geological calamity . JIAOCHENG region, NINGDE city lies in costal hill region in the North of FUJIAN province , with the speed up of step building strait west-shore economic region , Successive increasing in scale and strength of all kinds of human engineering activities , result in the incoordination of geological environment around , and lead to the happen of geological calamity frequency . and make great loss of people lives and property, so influence the local economic development.JIAOCHENG district NINGDE city lies in coastal region in north FUJIAN province . Ferrain reduces from north and south two sides to mid, and take shape that west , north , south three section high , and east section descend as three stairs , is one of many geological calamity region in FUJIAN province .so , land source section appoint 《investigation and distriction of...
