Research On The Delimitation Strategy Of Ecological Control Line In The Characteristic Zone Of Jiangnan Water Town In Southern Suzhou

Urban development is often accompanied by the acquisition of ecological resources.The extensive expansion of urban areas leads to the fragmentation of habitats and the excessive use of ecological land.As the country attaches more and more importance to the construction of ecological civilization,it is of great significance to study the relationship between ecological development and economic and social construction.This study studies the existing ecological problems in the current construction and development of Jiangnan Water Town.Based on the ecological and planning perspective,based on the comprehensive study of landscape ecology theory,green basic theory and “anti-planning” theory,The characteristic zone of Jiangnan water town is the research object,explore the method of delineating the ecological control line,expand the theoretical system,and use this as a basis to propose the feasible countermeasures of ecological space optimization within the research scope.This paper takes the Wujiang Pingwang Town,located at the core of the Jiangnan Water Town Ecological Belt,as the main research area,and uses the landsat8 series satellite image provided by the China Geospatial Data Cloud as the main data to study the impact of the ecological control line through ArcGis and other software.The intrinsic law of factors is combined with the study of the change law of land use affected by the expansion of built-up areas between 2005 and 2018,which makes the results more precise and gradient.The mathematical correlation between the logistic regression model and the logistic regression model was verified by Origin statistical software.The identifiable ecological patches in Pingwang Town were classified according to the value of the landscape connectivity index,which provided the subsequent evaluation of the ecological patch evaluation model.Parameter factor.In this paper,the road traffic network is used as another influencing factor of the evaluation model.Connefor 2.6 is used to analyze the interference value of the road network in the multi-threshold scenario to the possible connectivity index of the whole town ecological plaque,and to link the quantified land evolution law and important plaque grading.The index establishes the core plaque comprehensive recognition model,and uses the morphological spatial pattern to analyze and verify the model delineation results,and based on this,the ecological control line is delineated.The multi-method and multi-channel analysis and treatment of the Pingwang Town ecological control line is initially delineated.The author believes that the core area of ecological control is mainly distributed in the core ecological patches such as lake water system,and its ecological value is mainly reflected in the larger scale and connectivity.In two aspects,and as a whole,the spatial pattern of ecological patches is clear,but due to its uneven distribution in Pingwang Town,the ecological level is not balanced.Therefore,this paper takes Pingwang Town as an example,and proposes an ecological space optimization strategy while delineating the ecological control line.On the one hand,it strictly controls and protects the core plaques and core corridors with ecological resources advantages.A certain number of broken plaques can be used to repair the ecological environment and create a local ecosystem to compensate for the uneven distribution of core plaques by means of connection and darning.Through the above research,it is expected to form a reasonable and efficient control of the urban ecological space in the waterfront area of southern Suzhou,effectively alleviate the contradiction between regional construction and ecological protection,and actively promote the sustainable development of the characteristic zone of Jiangnan water town.
