Urbanization Induced Environmental Disturbance Characteristics In The Karst Mountainous Region Of Jinan

Karst mountainous topography occupy nearly a third of the total land area, iscomplicated, the ups and downs is bigger. Shandong province is one of the importantdistribution of karst region in north China, soluble rocks outcropped area of about16200km2, Jinan southern mountain area of karst area alone is about3500km2,accounting for21.6%of the whole karst area in Shandong province, accounting foralmost40%of land area of Jinan. But under the background of rapid urbanization,with the continuous development of karst mountain area of Jinan, a series of such asdesertification, fragile ecological environment, land subsidence and other disturbancesin karst mountainous area stable environment problem more and more prominent.Based on Jinan karst mountain area as the study area, this paper adopts thecombining theory with practice, indoor research and field investigation phasecomplement the technical route, build the Jinan southern mountain karst environmentdisturbance index (tolerated because) model, the influence from the karst landforms ofthe disturbance of environment factor, hydrological factors and biological factors,cultural factors of the four major are analyzed to explore the influence factors.Based on karst disturbance index score standard, using of EXCEL and SPASSsoftware specific indicators declare guilty of affecting the karst environmentdisturbance factor scores of interpretation. Combined with the current situation ofurbanization and rapid development of Jinan, and through the analysis of the surfacemorphology change and soil condition in karst area, can be concluded that thequarrying and mining in human activities, the degree of soil erosion and compactioncharacteristics factor will be a corresponding impact on landscape change in karst area.And the change of water quality and quantity in karst area, especially the change ofwater level and can cause disturbance of hydrological factors of karst environment.Vegetation disturbance condition in the study area, such as vegetation coverage andthe change of the characteristic factor such as population density will result in changes occurred in the biological factors in karst area, in turn, affects the ecologicalconditions in karst area. Jinan karst mountainous area has a wealth of tourismlandscape resources, in this article, through a large number of field investigations ofhistorical sites in the study area, daily management work in karst area is analyzed, andinfrastructure construction three aspects delve into its function and influence ofcultural factors of karst environment.Under the background of rapid development of urbanization, this article throughto the study of karst mountain area of Jinan disturbance characteristics analysis, therelevant conclusions and put forward the corresponding control measures, in karstregion will cause all the characteristic value of the disturbance of environment to aminimum, eventually realize the harmonious development of man and nature.Finally, it will summary the main achievements and the deficiencies of research,as well as carries out prospect of the development direction of this research field inthe future.
