Feasibility and ecological value assessment of roof greening in the central urban area of southern Jiangsu
摘要
Abstract
[Objective] A scientific and systematic assessment of the feasibility and ecological value of urban roof greening construction is the prerequisite for a safe and sustainable exploitation of the idle roof resources in cities. It also profits urban ecological environment and assists city planners and managers in their decision-making regarding green roof development.[Method] This study selects the center area of Xinbei District, Changzhou City as a target and aims to build an index system for the feasibility and ecological value assessment of urban roof greening. Remote sensing image technology is employed to collect data for the index system, combined with raster image overlay and reclass methods in ArcMap software for construction feasibility evaluation. [Result]These methods reveal that in the total roof area of ap-proximately 150500 m2 , 72600 m2 proves suitable for roof greening, among which 19600 m2 is fit for intensive green-ing, 40000 m2 for semi-intensive greening and 13000 m2 for extensive greening. After feasibility assessment, market value method is then applied to analyze the ecological value of roof greening in the center of Xinbei District from four as-pects, namely, air quality promotion, carbon fixation and oxygen release, energy conservation, and rainwater adjustment. The ecological value is found to be 16.87 Yuan ( RMB) / (m2·a).[Conclusion]The study comprehensively analyze the feasibility and sustainability of roof greening construction in the study area, and help to improve the efficien-cy of the use of urban building roof.关键词
