“…Urban green spaces can be defined as outdoor places with significant amounts of vegetation, which exist mainly as semi-natural areas (Jim and Chen, 2003). As cities continue to sprawl and urban populations continue to grow, the remaining nature within cities becomes disproportionately important (Crane and Kinzig, 2005).…”

► The green space coverage in Chinese cities increased steadily from 1991 to 2009. ► Cities in the same region exhibited long-term similar trends of development. ► Population, land area and GDP significantly affected green space coverage. ► Per capita GDP had the highest independent contribution to green space coverage. ► A linear model to predict variance in green space was constructed. a b s t r a c t a r t i c l e i n f o Irrespective of which side is taken in the densification-sprawl debate, insights into the relationship between urban green space coverage and urbanization have been recognized as essential for guiding sustainable urban development. However, knowledge of the relationships between socio-economic variables of urbanization and long-term green space change is still limited. In this paper, using simple regression, hierarchical partitioning and multi-regression, the temporal trend in green space coverage and its relationship with urbanization were investigated using data from 286 cities between 1989 and 2009, covering all provinces in mainland China with the exception of Tibet. We found that: [1] average green space coverage of cities investigated increased steadily from 17.0% in 1989 to 37.3% in 2009; [2] cities with higher recent green space coverage also had relatively higher green space coverage historically; [3] cities in the same region exhibited similar long-term trends in green space coverage; [4] eight of the nine variables characterizing urbanization showed a significant positive linear relationship with green space coverage, with 'per capita GDP' having the highest independent contribution (24.2%);[5] among the climatic and geographic factors investigated, only mean elevation showed a significant effect; and [6] using the seven largest contributing individual factors, a linear model to predict variance in green space coverage was constructed. Here, we demonstrated that green space coverage in built-up areas tended to reflect the effects of urbanization rather than those of climatic or geographic factors. Quantification of the urbanization effects and the characteristics of green space development in China may provide a valuable reference for research into the processes of urban sprawl and its relationship with green space change.

Unplanned urbanization has caused serious ecological imbalances in Dhaka city. This study investigates the efficiency and utilization of urban green space especially parks of Dhaka city. The case study site covers urban parks of Dhaka metropolitan area of Bangladesh. Two aspects (physical and social) were applied for this study. For physical aspect, methods were used RS (Remote Sensing) and GIS (Geographic Information System) of three periods of images (Dhaka city). And for social aspect, methods were used questionnaire survey, observation, photographs, sketch and previous information about parks. After calculating all data result was showed by maps using GIS. For the changing pattern of green space of periods 1972, 1989 and 2010, result showed that the variation of the green space changes rate was high and gradually green space deceased and build up area increased in Dhaka city. Again according to physical size, parks of Dhaka city were classified into four types: Small, Medium, Large and Extra Large parks. Small parks of Dhaka city were situated beside the residential area and were used as daily purpose. Medium parks were located beside commercial area and its use was for daily and weekly. Large parks were placed at city center and only one extra large park was found outer range of city area. In large parks, people mainly visited monthly or occasionally. Moreover, the spatial-temporal changes of images showed the present status of green space of the city. The consequence of the study reveals that the utilization of park was controlled by various factors in Dhaka city.

“…The least-cost path method has been used to identify paths that connect ecologically valuable areas by calculating all cost-surfaces pertaining to wildlife mobility for ecological planning [7,69]. Related research involves analyses of network patterns of local communities [70], road construction and traffic scenarios in industrial areas [71,72], plans for urban green networks and coastal eco-networks [73,74], and green networks through connectivity assessments of wildlife [64,75,76]. In this study, the least-cost path method is used to select the optimal area for replacement wetland that can ecologically compensate for a cost area.…”

This paper presents an integrated approach to mitigation wetland site selection using functional landscape connectivity and landscape structure. This approach enables landscape designers to evaluate the relative priorities of mitigation wetland areas based on functional landscape connectivity and wildlife mobility, as well as landscape structure, composition, and configuration. The least-cost path method is used to evaluate candidate sites for mitigation wetlands with regard to wildlife movement. A set of assessments for landscape indices using FRAGSTATS was applied to identify suitable mitigation wetland areas on the basis of landscape connectivity, composition, and configuration. The study was conducted in Gwacheon, Korea, where there are plans for regional development that will change the landscape. In the first step, a group of 14 candidate sites is identified via analysis of functional landscape connectivity using the least-cost path method. In the second step, candidate mitigation wetland areas are ranked according to landscape connectivity and composition. The five mitigation wetland areas that were found to be suitable were analyzed based on landscape configuration at the class level. This study demonstrates OPEN ACCESSSustainability 2015, 7 3387 that functional landscape connectivity and landscape structure are important aspects to consider when identifying suitable sites for mitigation wetland planning and restoration.
