Abstract
In order to achieve a sustainable urban environment, the increase of green space areas is commonly used as a planning tool and adaptation strategy to combat environmental impacts resulting from global climate change and urbanization. Therefore, it is important to understand the change of green space areas and the derived impacts from the change. This research firstly applied space analysis and landscape ecology metrics to analyze the structure change of the pattern of green space area within the Taipei Metropolitan Area. Then, partial least squares were used to identify the consequences on microclimate and air pollution pattern caused by the changing pattern of green space areas within the districts of the Taipei Metropolitan Area. According to the analytical results, the green space area within Taipei Metropolitan Areas has decreased 1.19% from 1995 to 2007, but 93.19% of the green space areas have been kept for their original purposes. Next, from the landscape ecology metrics analysis, in suburban areas the linkages, pattern parameters, and space aggregation are all improving, and the fragmentation measure is also decreasing, but shape is becoming more complex. However, due to intensive land development in the city core, the pattern has becomes severely fragmented and decentralized causing the measures of the linkages and pattern parameters to decrease. The results from structural equation modeling indicate that the changing pattern of green space areas has great influences on air pollution and microclimate patterns. For instance, less air pollution, smaller rainfall patterns and cooler temperatures are associated with improvement in space aggregation, increasing the larger sized green space patch.
Highlights
The threat of disaster brought on by global climate change has captured the attention of most of the world’s nations
With regard to spatial data conversion, we converted the spatial data from vectors into grid form, and re-categorized the land-use patterns of the Taipei Metropolitan Area from cartographic material provided via the National Land-Use
In accordance with the results of landscape ecological metrics is shown in Table 4 and the spatial change status of green space in the Taipei Metropolitan Area from 1995 to 2007 is shown in Appendix
Summary
The threat of disaster brought on by global climate change has captured the attention of most of the world’s nations. Solutions to these threats fall primarily into two categories: mitigation and adaptation The former emphasizes removing the causes of climate change to reduce the effects of the problems it poses. Current mitigation strategies target the reduction of greenhouse gas emissions in specific sectors (such as energy, industry, transportation, residential, commercial, etc.) The latter solution—adaptation—emphasizes responding and adjusting to the results of climate change, while reducing the damage it causes, possibly turning it to an advantage [2]. Because green space in metropolitan areas provides many functions, the development and planning of green space is an important way to mitigate and to adapt the environmental impact of climate change and over-urbanization while helping to achieve sustainable development goals. The conclusions and suggestions are proposed in the final section
