Multidimensional effect analysis of typical country park construction in Shanghai

Abstract

In the history of country park studies, little attention has been given to evaluating the vitality of country parks, the comprehensive ecological, living and production benefits of country park construction, and the change in the carbon emission effect. The goal of this article will be to address these three issues. Based on multisource data, a country park vitality index system, regional comprehensive benefit evaluation index system and land use carbon emission estimation model were constructed to conduct quantitative estimation. The results showed that (1) the popularity index rather than the accessibility index was the key component of the vitality of country parks, followed by the connectivity index and the land use diversity index. (2) Ecological space and public open space in most of the whole land consolidation areas that centred on country park construction were significantly expanded, traffic accessibility and housing conditions were significantly improved, population agglomeration and landscape diversity index tended to increase, and the comprehensive goal of synergistic improvement in production, living and ecological benefits was achieved. (3) The whole land consolidation area dominated by country park construction had a better carbon emission reduction effect. Reducing inefficient construction land and increasing forestland are important measures to reduce carbon sources and increase carbon sinks. The results of this study have guiding value for the improvement of country park planning and construction and the optimization of the whole land consolidation area in Shanghai.
