Urban center urban park greenbelt ecological network evaluation system and method

Abstract

The invention discloses an urban center park greenbelt ecological network evaluation system and method, and the method comprises the steps: obtaining a greenbelt ecological network of an urban centerurban area, and dividing an urban ecological space system of a target region into three space regions; on the basis of a satellite image map of a target urban area, applying an ArcGIS10.3 geographic information technology to establish a greenbelt type database, carrying out weighted association between a greenbelt ecological network and three space areas, constructing a greenbelt ecological network evaluation system, and carrying out comprehensive analysis and evaluation on the structure and the function of the greenbelt ecological network in a research area. By implementing the method, a harmonious, stable and sustainable evaluation standard is provided for the urban central urban green land ecological network, the space structure and the ecological function of the green land ecological system are perfected, and the healthy development of the urban green land ecological system is guided. The method has important significance for scientifically planning a central urban green land ecological network and guiding the green land space to develop and construct in an ordered and healthy direction.

Description

technical field [0001] The invention relates to the field of ecological network evaluation of urban green space, in particular to a system and method for evaluating the ecological network of park green space in urban central urban areas. Background technique [0002] As an important part of urban planning, urban green space system planning is a key policy for the overall arrangement of green space resources, guiding the orderly development and construction of urban green space, and protecting the public interests of citizens. And ecological function is an important strategy for building a new type of ecologically sustainable development city, and it is an important display of the concept of ecological civilization in the construction of new urbanization. [0003] The national ecological civilization construction policy puts forward newer and higher requirements for urban green space planning and construction. However, the quantitative analysis and evaluation of urban green s...
