Study On The Repairing Strategies And Pathway Of Damaged Mountain In Typical Area Of Guifeng In The North Mountains Of Qinling

It is the ecological environment that suffered varying degrees of damage for the stone and material mining of the North Mountain of Q inling. However, repair damaged a mountain exist some characters such as theory blank, lack of practice, and repair urgently. In this background, for the purpose of the damage of degraded ecosystem restoration in this paper. By the means of field investigation, literature citation, system research, from the methods such as typical cases and so on. damaged mountain ecological restoration strategies were combed, damaged mountain repair pathways were concluded. and the case of domestic existing damaged mountain to repair were studied. Taking the degraded ecosystem of damaged mountain of typical areas repair to do case study in Guifeng of Q inling. It is the significant that solve the degradation of ecological environment in theory and practice.This paper is divided into six chapters. The first chapter is the introduction which elaborated the background, purpose, significance, content, methods,framework and the research innovation of this paper is p resented. The second chapter is the review, Firstly, overview the related theories and concepts. Secondly,summarize the effect study on damaged mountain ecological restoration of home、abroad and the Q inling. Finally, the domestic damaged mountain repair engineering practice case of repair methods and governance has carried on the induction and summary. Provides the theoretical basis for the following study on the practice. The third chapter combs the situation of research base. the status quo of the problems are analyzed, and the causes a nd hazards of the damaged mountain were summarized. Analyzed the three typical characteristics of the damaged mountain. The fourth chapter is the feasibility repair strategy research part of the three typical features of damaged mountain. Including the typ ical slope feasibility repair strategy:“Kaiping machine cutting slope”,“Masonry scale- hole”,“Bird’s nest turns green”,“Vegetative slot ridging p lanting”;Typical geological lithology repair strategy:“Physical modified repair”,“Chemical modified repair”,“Plant modified repair ”,“Micro-organisms modified repair”; vegetation recovery strategy: “Pure forest community recovery pattern”,“Mixed forest community recovery pattern”,“Climbing plant community landscape restoration”,“Halosols deserts with plant community recovery pattern”,“Landscape pattern of forest community recovery”. The fifth chapter is the ecological restoration approach research part of typical areas of damaged mountain in Guifeng. By applying the theory of ecological succession, and feasible repairing strategies used in damaged mountain restored, In theory to guide practice,argumentation theory by practice. the sixth chapter is the conclusion part,O verview of the integration research content of the paper and introduce the shortage of the research in this paper. At the same time, put forward looking for follow-up study of this article.The paper is bsed on the typical section of damaged mountain to repair in Guifeng,provided the technical support for the restoration of damaged mountain of north mountain of Q inling. There are three innovation points: The first is that three typical features were summarized of the north mountain of Q inling: The slope foot in more than 75 o, Geological lithology include the carbonate rocks and fine clastic rocks, Vegetation pattern to the top of the mountain coniferous forest community,Mountainside forest community,Mountain foot bringing forest community. The second is that feasible to repair strategies were proposed for the three typical. Kaiping machine cutting slope repair strategy was taken for the slope,physical improvement repair strategy and plant improvement repair strategy were used on the Geological lithology. In terns of vegetation landscape features,pure forest community recovery strategy was used on the top of mountain, mixed forest and rock climbing vegetation recovery strategy were used on the mountainside, landscape forest community recovery strategy was used on the hillside. The third is that the ways out of the damaged mountain ecological restoration technology roadmap is establishmented namely:step one the broken mountain investigation and evaluation、step two the target and the content of repair is put forward、step three unstable slope manage、soil remediation、 blocks for vegetation landscape restoration;step four the species of vegetation selection and the pattern of vegetation restoration.
