The evaluation system and methods designed for estimating the developing maturation of recreation belt around metropolises

Abstract:
The article puts forward the concept of Developing Maturation of ReBAM (Recreation Belt around Metropolises) on the basis of recent ReBAM researches which have the tendency towards micro-viewpoint and its relationship with regional environment. The concept is used to describe the developing status of ReBAM in the whole or some special regions. The authors design the evaluation system and methods which include 4 standards and 13 sub-factors. The 4 standards are interior structure, region integration, supporting facilities, and information in Internet. Using the evaluation system and methods, we can realize the quantitative evaluation of ReBAM, and based on the result scores the ReBAM will be classified into 4 developing maturation statuses: embryonic stage, developing stage, approaching maturation stage, and maturation stage. The authors select Beijing city as the case, and divide the Beijing ReBAM into 13 circle-shape regions according to a 10-km distance standard from city center to the farthest edge of ReBAM. On this basis, the authors evaluate the developing maturation status of each circle-shape region using the evaluation system and methods. The evaluation result shows that the Developing Maturation of Beijing ReBAM presents evident spatial differentiation characteristic. In general, the farther it is from the city center, the lower degree of Developing Maturation in the area, but there is also evident waving in the general pattern. The 40-100-km circle-shape regions in Beijing ReBAM are the more active regions in developing, and they will become the major regions for developing in the ReBAM, and tend to maturation.
