“…As cities continue to sprawl and urban populations continue to grow, the remaining nature within cities becomes disproportionately important (Crane and Kinzig, 2005). Typically, urban green spaces have important ecological effects, contribute to public health, and increase the life quality of urban citizens by offering esthetic enjoyment, recreational opportunities and improvements in physical and psychological well-being (Jo, 2002;Chen and Jim, 2008). Recent reports also found that carbon density in urban areas (23-42 kg C m −2 in sample cities of the United States, Churkina et al, 2010;3.16 kg C m −2 in Leicester, UK, Davies et al, 2011) is comparable to that of some natural forests, and the dynamics of urban vegetation may leave footprints in global biogeochemical cycles (Grimm et al, 2008).…”

► 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.

“…Greenspace has significant ecosystem services, which are defined as "the benefits human population derives, directly or indirectly, from ecosystem functions" (Costanza et al, 1997). It can sequester carbon dioxide emissions and produce oxygen (Jo, 2002), purify air and water, regulate micro-climate, reduce noise (Bolund and Hunhammar 1999), protect soil and water (Pauleit and Duhme, 2000;Jim, 2001), maintain biodiversity (Attwell, 2000), and have recreational, cultural and social values (Savard et al, 2000;Tarrant and Cordell, 2002). Furthermore, greenspaces such as public parks, natural areas and golf courses can have a statistically significant effect on the sale price of houses in close proximity to those resources (Bolitzer and Netusil, 2000;Luttik, 2000).…”

Greenspace is an important part of complex urban ecosystems and provides significant ecosystem services. It benefits urban communities environmentally, esthetically, recreationally and economically. Beijing Province is in north of China, and has a total area of 16,807.8 km 2 and a population of about 13.8 million. This paper aims to develop a comprehensive conceptual framework for urban greening of Beijing Province based on landscape ecological principles. It attempts to answer how to establish an urban greening plan at the regional, city and neighborhood levels to achieve long-term sustainability. At the regional level, a big natural and semi-natural forest area in the northwest and an ecological buffer belt in the southeast are planned to protect the environmental quality of Beijing and provide habitats for wildlife. At the city level, a green network system of green wedges, parks and green corridors has been proposed. This green network helps to limit future urban expansion, improve urban environmental quality and serve as habitats and migration routes for wildlife. At the neighborhood level, green extensions and connections of riverside greenway, road greenway, parks and vertical greening permeate into the built-up areas. They provide open space close to residential areas and offer places for recreation. This three-level green system constitutes an integrated ecological network for urban sustainable development of Beijing. For future development of Beijing, urban parks, forestry, agriculture, water and infrastructure should be planned and designed in an integrated way. After this greenspace plan is legislated and completely realized, Beijing will develop an interconnected and integrated network of urban greenspaces. It has the prospect of achieving the aim of "Green Olympic City 2008" and the long-term goal of developing Beijing towards an "Eco-City".

“…Simulations of water balance components were done for a sandy loam soil with a nearly level and bare (non -plant-covered) surface, since the soils in the region are predominantly gravelly loam or sandy loam (Jo, 2002). However, daily computations of evaporation (or evapotranspiration) were carried out not only for a bare plot but also for a grass reference surface during the period of 1980 to 2009.…”

The hydrological components of a sandy loam soil of nearly level in Chuncheon over 30 years were computed using the E-DiGOR model. Daily simulations were carried out for each year during the period of 1980 to 2009 using standard climate data. Reference evapotranspiration and potential soil evaporation based on Penman -Montheith model were higher during May to August because of the higher atmospheric evaporative demand. Actual soil evaporation was mainly found to be a function of the amount and timing of rainfall, and presumably soil wetness in addition to atmospheric demand. Drainage was affected by rainfall and increased with a higher amount of precipitation and soil water content. Excess drainage occurred throughout rainy months (from July to September), with a peak in July. Therefore, leaching may be a serious problem in the soils all through these months. The 30-year average annual reference evapotranspiration and potential soil evaporation were 951.5 mm and 714.2 mm, respectively. The actual evaporation from bare soil varied between 396.9-528.4 mm and showed comparatively lesser inter-annual variations than drainage. Annual drainage rates below 120 cm soil depth ranged from 477.8 to 1565.9 mm. The long-term mean annual drainage-loss was approximately two times higher than actual soil evaporation.
