基于碳氧平衡模型的城市公园生态效应评价研究

温室效应所引起的气候变暖严重影响着人类的生存和发展,同时严重制约着城市的可持续发展。基于此,主要结合碳氧平衡模型进行城市公园生态效应评价,首先结合碳氧平衡模型以及AHP(层次分析法),选择合适的指标,构建基于碳氧平衡模型的城市公园生态效应评价体系。然后具体结合成都市高新南区进行实证分析,搜集碳氧平衡相关数据,对其CO2排放量、CO2吸收量以及碳氧平衡缺口进行计算,并结合上述的模型选取区域内最具代表的锦城湖湿地公园为具体的生态效应评价对象,得到区域生态效应情况。最后结合评价的结果提出优化城市生态效应的建议。

Research on Evaluation of Ecological Effect of Urban Park Based on Carbon-Oxygen Balance Model

The climate warming caused by the greenhouse effect has a serious impact on human survival and development,and at the same time seriously restricts the sustainable development of the city.Based on this,this paper mainly combines the carbon and oxygen balance model to analyze the ecological effect evaluation of urban parks.Firstly,the paper combines the carbon and oxygen balance model and AHP(analytic hierarchy process),selects the appropriate indicators,and constructs the ecological effect evaluation system of urban parks based on the carbon and oxygen balance model.Then combined with Chengdu High-tech South District for empirical analysis,the paper collects the carbon and oxygen balance data of the case,calculates the CO2 emissions,CO2 absorption and carbon and oxygen balance gap.Combined with the above model,the most representative Jincheng Lake Wetland Park in the region is selected as the specific ecological effect evaluation object,and the regional ecological effect is obtained.Finally,based on the results of the evaluation,some suggestions are put forward to optimize the urban ecological effect.
