Geological Heritage Landscape Characteristics And Preliminary Genetic Analysis In Lanping Area,Yunnan Province

Geological relics reflect the history of local geological evolution and are the important basis and main carrier for people to understand geological phenomena,speculate geological evolution and restore geological history.They have high scientific research and popular science education value.Lanping area,Yunnan Province,is located in the parallel flow zone of the three rivers.It has a large number of geological relics landscape,especially the distribution of geological relics formed by neotectonic movement.These geological relics record the important geological evolution events in the area.The process and trace of geological structure formation,etc.By collecting the relevant data of geological relic landscape in Lanping area,this paper summarizes the characteristics of geological relic landscape in Lanping area and analyzes its genesis.First of all,with the support of Sentinel-2A remote sensing data and GIS technology,combined with the traditional field geological relic landscape survey method,a set of interpretation marks suitable for various types of geological relic landscape in the study area is established.Secondly,through the field investigation,the classification,distribution characteristics and development conditions of each type of geological relic landscape in the study area are found out as a whole,and the main geological relic landscape in the study area is comprehensively evaluated.To establish the classification system of geological relic landscape in Lanping area.Finally,the previous relevant studies are summarized,and the basic theories and research methods,such as geology and physical geography,are applied to the integration of various disciplines,from the regional lithology,tectonic background and Quaternary glaciation.The formation conditions of geological relic landscape are comprehensively analyzed from the aspects of neotectonic movement.The results show that the Danxia geomorphological landscape in Lanping area is due to the complex geological structure evolution,coupled with the accumulation of huge red debris of Baoxiangsi formation and Jinsichang formation in the long geological history period,and the strong neotectonic movement occurred in the later stage.The cutting effect of deep and large fault structures and joints on geomorphology leads to the formation of rich types of Danxia geomorphological landscape in this area.The glacier-snow mountain landscape is a geological and geomorphological change in the evolution of geological history,especially since the Cenozoic.Under the influence of the Himalayan orogeny,the northwestern region has been continuously uplifted and uplifted,and many mountain ranges in the study area have followed.It has been continuously raised,and the glaciers cover most of the area and continue to function.Under the strong carving of early ice and snow,it has shaped the spectacular glacier landscape in the study area.The plateau wetland is located in the deep cutting mountain canyon area,the terrain is steep and the precipitation is more,the weather is cold,the terrain fluctuation is small,in this kind of climate environment,the whole area begins to form the tectonic ice erosion basin.And began to develop to form plateau wetlands.Through the study of this paper,it is of great significance to excavate different landscape geography,geo-scientific research and popular science resources in Lanping area,and to protect them effectively.
