The Research Of Protection And Usage Of The Urban Natural Mountains In The Shallow Hill Areas

With the accelerating urbanization in our country,city scale is expanding gradually, leading to the result that the contradictions of urban construction land and protection of land are becoming more and more prominnent.Especially in the shallow hill area, in the process of urban construction, the human beings fully tap to the potential of constrction land in the city, and they dig mountains to fill their lives, resulting in the original natural mountains and valleys broken and separated. A part of saved and remaining mountains, valleys and steep slopes become the isolated island of urban natural terrain, which brings about the result that many city mountains are damaged, the urban environment quality greatly decline, city disasters frequently increase, and residents’quality of life of leisure space environment is polluted. In order to effectively protect and use the natural mountains in the city, which can make the city and natural mountains mutual fused and make the urban mountain lanfscape better visible. We can constitute the urban landscape pattern of the compatibility of the city, the mountain and the forest. Therefore, there are many pratical significances in the research of protection and usage of the urban natural mountains in the shallow hill areas.This article chooses Zigong city with the shallow hill area landform characteristics as the research object, which researches on the natural mountains closely related to the urban landscape of natural mountains in the center area of Zigong city, briefly analyzes the impact on the natural mountains in the process of urban expansion, analyzes the existing problems of the protection and usage in the process of urban development, and states the way of the mountain line defined. On the background of rapid development of city construction, some significant intrusion has appeared on the research of the urban mountain in shallow hill area as the important landscape element in the city. It contains the formation of the urban landscape pattern that human and the nature harmoniously coexistent by the city planning and construction control, which can make the destruction to the natural environment of the urban construction lest, make the full use of the function and beneficial of natural mountains in the city, meanwhile, also can serve residents’living environment, meeting people’s leisure entertainment functions, making them more close to natural and protecting the ecological environment. The core content of the article contains as follows:First, the article makes a further discussion about the research on the protection and usage of natural mountains and the way of the mountain line defined by the introduction and the related theories.Second,building of evaluation system, which defines the natural mountain line, and researching method of the mountain line.Third, through the investigation and analysis of the mountain within the center of Zigong city, natural mountains in the center of Zigong city can be divided into three types which are primordial hill, half a primordial mountain and artificial mountain according to the development of strength.Forth,based on the research about the relationship of natural mountains, citizens and urban landscape effect in the center of Zigong city, there exists the important problems of the natural mountain protection and usage in the process of urban construction.Fifth,from the perspective of urban development, it summaries the principles and patterns of mountain protection and use in the center of Zigong city, and explores for planning method of the city natural mountain protection, development and utilization in the shallow hill area by the relevant theory and the research on natural mountain guide, and measures for the management in the center of zigong city.This article preliminarily discusses the protection and utilization of natural mountain center of zigong city. It builds the evaluation system of the mountain line designated, and sums up the principle and mode of protection of the natural mountain in the center of Zigong city, which can provides ideas and technical support about future urban natural mountain protection and utilization of shallow hill, and also can provide feasible reference and basis of the landscape building urban green space system and urban planning and design in the shallow hill area. Therefore, the sustainable development of the urban construction and natural environment construction can come true, consequently, the purpose of protecting the city ecologically natural landscape pattern has been achieved.
