Study On The Ecological Transformation Of River Hard Landscape In City With Nanjing City As An Example

River, river and waterfront is the essence of the city landscape, winding, graceful and lively city riparian landscape not add much charm and charisma! Due to the weak consciousness of ecological and landscape, city flood control and water conservancy engineering disaster prevention and mitigation of one-sided pursuit of decades or even a hundred years of safety, high dam, thick slope, Qing vegetation, a flat, generally neglected landscape ecological characteristics of the river. The survey found, only Nanjing city river traditional revetment engineering mortar rubble accounted for 90%. The masonry is widely used not only violates the construction law of harmony between man and nature, relationship from rivers and land, to obliterate the city unique personality, but also cause serious ecological disaster.In view of the present stage city river hard seriously, river ecosystem balance and biodiversity is under serious threat, the grim reality of sustainable water landscape city faces challenges, this thesis uses literature analysis, field survey, induction and deduction, empirical research and other research methods, in the question foundation, relevant theories on city landscape ecological reconstruction the organized and summarized, analyzed and basic methods of ecological restoration of domestic and foreign city river landscape case, clearly pointed out the defects and shortcomings of mortar rubble revetment city water and flood control engineering. In summarizes the predecessor theory and on the basis of practical experience, put forward in do not break the traditional mortar rubble revetment premise, ecological restoration of slope revetment and hard landscape, ecological environment of wetland and planting vines to restore, update, transformation of the degradation effect of digestion, hard surface on river ecological system, through the engine plant time spatial and seasonal variation, color, rich river landscape, reshape the vibrant city waterfront living space.In the fourth chapter, through the stone landscape and ecological deficit induction, the ecological transformation of evaluation standard, emphasize the importance of ecological engineering and plant communities of choice, and the vines were screened, finally sums up the suitable technical measures of ecological engineering in Nanjing area and the appropriate liana species.Do not destroy the mortar rubble revetment surface, application of plant ecological characteristics of the outstanding characteristic of this article is distinct, both at home and abroad, the research area is still relatively small, so this study has a certain theoretical value and practical significance to promote.
