Karst Landscape Features And Protection Countermeasures Of Daba Mountain National Geo-Park

Daba mountain national geo-Park located to the southern margin of Dabamountains northeastern Sichuan. It is located in intersection of Xuanhan County andWanyuan city in Dazhou, Sichuan province. Park belongs to the Qinba Northsubtropical climate zone. It is the transition zone between North and southern climate,and it has moderate climate, abundant rainfall. Its geotectonic location belongs tothe stransition part of Northwestern margin of the Yangtze block and Qinling orogenicbelt on Daba mountain arc structure belt, Is the combination part of Dabashanforeland basin and the orogenic belt northern margin of the Yangtze block, Its uniquetectonic location and location, creating a park of unique karst landscape.First reviews the research of karst landscape in the domestic and internationalsituation, secondly makes analysis on current research situation of Daba mountainnational geo-Park, there are few studies on Karst in the transition part between Northand South, and lack system studies on protection of karst landscape. Researchesabroad on the karst landscape mainly addresses the local karst landscape, they has thecertain reference value. Research within the Park is relatively low, only few coveredthe investigation of karst landscape, the potential economic value and benefits of karstlandscape people had already found that have not been further reflected， And how tothe rationally develop the karst landscape, how to appropriate protect the karstlandscape which have been developed need in-depth study. Subsequent, an in-depthstudy of formation of karst landscape’s geological setting，landscape types，landscape characteristics and conservation strategies. of the park.Research methods of this paper mainly are field route investigation andcomprehensive study on indoor information. On the basis of the collection, analysis ofprevious study results, then have field surveys. Focus on types, features and theprotection of karst landscape, after that transferred to the comprehensive study ofindoor stage, Analysis focused on karst landscape types, characteristics, features, andconstructive advice on its conservation strategy.Studies show that the tape of karst landscape of the Park is very rich. Accordingto the classification of karst landscape, karst landscape can be divided into surface andunderground karst landscape. According to their morphological characters，surface karst landscape can be divided into9species, there are karst rock dissolve peaks,Karst peak-cluster, cliffs, karst valleys, karst hieroglyphic mountains and rocks, karstdepressions, Karst funnels, karst springs and sinkholes in the karst funnel, Accordingto their morphological characters, the underground karst landscape can be divided intothe caves, underground rivers and underground Karst tunnel. Compared with karstlandscape at home and abroad, it can be seen that the park’s karst landscape is unique.,At last,based on the qualitative and quantitative evaluation of Park’s karst landscape,and analysis of influencing factors of karst landscape, presented to the Park karstlandscape protection countermeasures.
