The method includes the steps that firstly, in a panzest and piz master thesis 'updated evaluation system and method research of the Changzhou old industrial area' of the southeast university, updating history and current situation of the Changzhou old industrial area are combined, updating influence factors are summarized, an updated evaluation index system comprising 4 aspects and 10 indexes of ecological environment, economic development, social humanity and regional integration is provided for the Changzhou old industrial area, and finally 8 existing industrial areas in the area are evaluated. However, there are three disadvantages in this evaluation system: firstly, the evaluation system has a small application range and strong pertinence, and only considers the development and the current situation of the old industry area of the Changzhou; secondly, the evaluation system does not form a scientific quantifiable operation process and is only realized on 8 old industrial area cases in the Changzhou range, and an evaluation method system of a scientific system is lacked; thirdly, the content covered by the evaluation index is not comprehensive enough, and the evaluation content in the aspects of ecological greening, operation management, personnel experience and the like is lacked.
Secondly, the existing evaluation standard is mainly aimed at the evaluation of newly built buildings, newly built communities or urban areas, and the related evaluation standard JGJT 425 and 2017 'the existing community greening transformation technical standard' is also mainly aimed at the evaluation of the greening transformation of the existing communities in five aspects of diagnosis, planning and design, construction, acceptance, operation and evaluation, and cannot be applied to the evaluation after the transformation and the upgrading of the existing urban industrial areas.
