| Ecological park is an important carrier of ecological civilization construction,and the construction of ecological park is one of the ways to solve regional and urban ecological environment problems.The logical relationship between spatial ecological attributes and spatial functions of ecological parks is not only a practical planning problem to be solved,but also an academic problem to be discussed.This paper focuses on the spatial ecological attributes and spatial functions of ecological parks,establishes the theoretical logic of spatial attributes and spatial functions,and provides a new planning perspective for the planning of functional space and functional areas of ecological parks.Based on the definition of ecological park,functions and spatial properties,core concepts,on the basis of systematically combing and interpreting the landscape ecology theory,attribute theory,theory of recreational space,natural reserve space model theory,and the theory of natural education ecology park planning theory,analyzes the ecological park at home and abroad and the research progress of spatial attributes and the construction practice,This paper discusses the planning method of ecological park based on spatial attribute analysis,and takes Xiqiao National Ecological Park as an example to demonstrate the scientificity and feasibility of this method.The main research results are as follows:1)Taking Xiqiao National Ecological Park as an example,terrain and landform,river system and water body,vegetation and plant diversity,wildlife diversity,land cover type,construction and structures that can reflect the ecological characteristics of the study area are selected as the criterion level indicators.Elevation,slope,water buffer zone of river system,vegetation type,vegetation coverage rate,wildlife habitat,land use type,building buffer zone,road buffer zone,etc.,were selected as index layer indexes to construct the evaluation index system of natural ecological attributes of ecological park space,and Yaahp software was used to calculate the weight value of evaluation indexes.2)The ecological authenticity of Xiqiao National Ecological Park is divided into three grades,which are high ecological authenticity,medium ecological authenticity,and low ecological authenticity.The comprehensive authenticity evaluation values are 5,3,and 1,respectively.Based on the evaluation of ecological authenticity,the spatial attributes of Xiqiao National Ecological Park were analyzed,that is,the area of high ecological authenticity is the space with natural attributes,which covers an area of 161.71hm2,accounting for 22.76% of the park area.The middle ecological authenticity area is the space with the characteristics of near natural attributes,with an area of 257.45hm2,accounting for 36.23% of the park area.The low ecological authenticity area is the space with human activity attribute,with an area of291.44hm2,accounting for 41.01% of the park area.3)The basic skills of xiqiao national ecological park can be: ecological protection,outdoor recreation,science education and landscaping,etc.Combined with the results of spatial attribute analysis and functional space appropriate scale analysis,and on the basis of functional space planning and adjustment,the functional space of Xiqiao National Ecological Park is divided into ecological conservation function space,ecological buffer function space and leisure and recreation function space,in which: The ecological conservation function space accounts for35.0% of the total area of the ecological park,the ecological buffer function space accounts for33.0% of the total area of the ecological park,and the leisure and recreation function space accounts for 32.0% of the total area of the ecological park.The functional space division conforms to the functional space theory model of natural protected area.4)From the perspective of spatial attribute analysis strategy and technology,Natural property of xiqiao national ecological park space(ecological conservation district,close to nature space(ecological buffer),human activities attribute space(recreational area)of the terrain and the vertical design,drainage water,wetland and migratory birds,traffic network,scenic spots,the main facilities,planning and design discusses ecological restoration. |
