The Loess Depression Natural Dam System Construction Of National Geological Park The Preliminary Research On The Basic Problem

The geological vestige is the resource which has value in use that the geological process creates and leaves behind, and it’s the important research object of geological science, it is also the important base of environment, widespread science and natural disaster research. Huangtuwa natural dam in Zizhou county is the oldest natural dam with full alleviation and sedimentation known in the Loess Plateau, which the thickness of loess sedimentary layer reached to more than50meters, the natural profiles of eolian loess and minase deposition loess are typical and worthy sightseeing in branch gully. And it has potential to establish minase deposition loess national geopark, so it need related research urgently. This paper selects huangtuwa natural dam system as studying object, using investigating method, literature collecting method, comparative analysis method, and the method of combining the theory with case analysis, according to the natural resources and social development in huangtuwa aera, the necessity of establishing national geopark of huangtuwa natural dam system has been analyzed, and the feasibility of establishing it has also been discussed using SWOT analytical method, and according to the analysis results, the development strategy of huangtuwa natural dam system of national geopark has been put forward. Moreover, function zones of it had been made using ARCGIS software, and its supporting facilities had also been initially planned. The concrete research results are as follows:(1)Huangtuwa area is the oldest natural dam with full alleviation and sedimentation known in the Loess Plateau in North Shaanxi, located in typical loess hilly region, and it’s the core region of coarse sand area in Loess Plateau. So, it is also the key research region of soil corrosion in Loess Plateau. Therefore, it has extremely high scientific research and ornamental value;(2)The reasons of establishing national geopark in huangtuwa area are the need of scientific research, tourists’sightseeing, the protection and government of ecological environment, and the popularization of social and culture knowledge, which reflect the necessity of establishing the national geopark of huangtuwa natural dam system.(3) Through the SWOT analytic method, the strength, weakness, opportunity, and threat of the establishment of the national geopark in huangtuwa area are analyzed systematically, the conclusions are as follows:The strength in huangtuwa area are the richness and and uniqueness of tourist resources, the support of local government and good ecological environment; The weakness are the low level development of economy, the tightness of money investment, the imperfectness of the infrastructures, such as transportation, the badness of health environmental condition in village and traveling seasonal characteristic of the tourism and so on; The opportunity are the protection of geological vestige and the development of the resource conservation industry which government does constructively, the fast development of village tourism and the springing up of holiday economy, the sustainable and rapid development of national economy and the implementation of western development strategy of China, the expansion of tourist market of Scientific investigation and fast development of low-carbon economy; The threat are the region competition in homogeneity resources, such as Luochuan Loess National Geopark, the increasing diversification of people’s traveling demand and dealing with the contradiction between development and protection. So, it concludes that it has both strength and weakness, not only opportunity but also threat in developing tourism in huangtuwa area. So it has feasibility to establish national geopark in huangtuwa area.(4) Through analyzing the feasibility of establishing national geopark in huangtuwa area by SWOT analytical method, the development strategy of huangtuwa natural dam system national geopark can be obtained. The concrete content are emphasizing eco-tourism, taking the development of popular science tourism as the main body, and paying great attention to the diversification of the form of tourism. For example, it can develop a tourism development model which includes many kinds of tourism programs, such as scientific research, browsing sightseeing, leisure picking and farm tourism.(5) The function district of huangtuwa natural dam system national geopark was made, which was divided into six functional area, such as core protection area of geological vestige of huangtuwa natural dam system, observation area of loess deposition profile, sightseeing area of slope terrace, national geological museum of huangtuwa natural dam system, leisure picking area and development and control region.(6)In addition, the national geopark of huangtuwa natural dam system should pay attention to the construction of traveling infrastructures, such as road and parking lot, tourist service facilities such as lodging, dining, trashcan and restroom construction and so on. as well as the construction of tourism engagement staff team.
