Abstract
Ecological space in a densely urbanized region plays a very important role in its development. Therefore, a scientific evaluation of ecological spaces in a densely urbanized region is the main prerequisite for corresponding ecological space planning. Taking the Wu-E-Huang-Huang Metropolitan Interlocking Region as the study area, the paper selects six types of ecological factors, including the location index, land status, terrain conditions (elevation, slope), hydrological conditions (rivers, lakes), landscape value, and road traffic. By using a single factor evaluation and a multi-factor comprehensive evaluation method involving GIS, the paper presents an evaluation of the ecological space conditions of the Wu-E-Huang-Huang Metropolitan Interlocking Region. In line with the result, the ecological environment of the region is divided into four levels: highly sensitive areas, sensitive areas, weakly sensitive areas and insensitive areas. On this basis, the underlying problems and mechanisms are explored further.
Highlights
In the process of new urbanization in China, gigantic densely urbanized regions have been formed due to the rapid development of cities and regions
Due to the swarming of people from the countryside into densely urbanized regions, the population and construction in these areas have been expanding quickly, which has been threatening the safety of urban ecological spaces
In light of the potential for growth and public health, a series of studies emerged with the goal of evaluating the eco-value or the sensitivity of the ecological space in highly-urbanized regions
Summary
In the process of new urbanization in China, gigantic densely urbanized regions have been formed due to the rapid development of cities and regions. During the early 21st century, ecological thoughts began to fundamentally direct the way that people sought to solve all lifestyle-related problems This has led to a major shift in attention towards nature-integrated urban and regional structure studies on the basis of “ecological orientation”. This idea was first summarized by an American scholar named Honachefsky, in order to deal with problems posed by an endless and disordered expansion of American cities [3]. In light of the potential for growth and public health, a series of studies emerged with the goal of evaluating the eco-value or the sensitivity of the ecological space in highly-urbanized regions These studies came from two main approaches.
