Evaluation of the impacts of urban forest in Beijing, China

Description

The location of Beijing

Background

Beijing, the capital of China (the People’s Republic of China), which is located in a transitional plant zone between South and North in China. Beijing City with over 13 million individuals holds a unique title of a direct-controlled municipality under the direct control of the Chinese government. The rapid economic growth and urbanization accompanied by severer air pollution, which is a threat to the health of Beijing dewellers. Under such circumstance, the Beijing urban forest plays an essential role in improving this city's environment. In Beijing City, the forestry coverage only accounts for 0.6% (104 km2) of the total area, which is approximate 16,808 km2. Based on the geographic location of Beijing, where is warm-temperate zone, deciduous broad-leaved forest takes up the most forestry area with much less coniferous forest in this region[1]. The Beijing dominated tree species include Pinus tabuliformis, Quercus spp., Acer spp., Koelreuteria paniculata, Vitex negundo var. heterophylla, Spiraea spp., Themeda japonica, and Lespedeza spp[2].

History

Huang et.al defined the urban forest as the tree population grows in the urban area with plants that can grow in the understory[3].

o Feng shui (wind and water in English) is the traditional idea regarding the forest to create harmony between nature and human, which is derived from 4000 BC and related to metaphysics in China[4].

o At the early of the 20th century, some Chinese environmental experts who studied abroad and introduced the concept of modern forestry to China attempted to build forests surrounding Beijing[5].

o In 1949, the new Chinese government proposed to launch the afforestation project both in the remote areas and the region near cities. There is no exception in Beijing. In order to conserve water and soil as well as provide recreation for city's residents, the municipal government constructed many plantations in Beijing[5].

o In the 1980s, modern urban forests started in China. During this period, the Chinese and municipal governments only focus on recreational activities and environmental conservation[4] [5].

o In the 1990s, the Chineses government regarded the long-term planning of urban forestry as a part of a strategy for national development [6].

o The 21st century, Chinese started to recognize the nature-human-urban forest interactions[4].

o In 2013, Beijing Forestry Bureau would establish over 10 urban forests, covering approximate 23,000 hectares in response to the national call for the reduction of severe smog in Beijing-Tianjin-Hebei region[7].

Arrangements

Tenure arrangements

The Chinese government owns the urban forests along streets and public parks in Beijing forever.

The developers of houses take control of the urban forests in separate residential areas by freehold for about 70 years; these forests are aimed at improving the neighborhood’s environment to make more profits when selling houses or apartments.

Administrative arrangements

The municipal government administrates the urban forests in Beijing indirectly; the municipal assigns Beijing Forestry Bureau to manage Beijing urban forests directly. The management of residence has been authored by developers to manage their urban forests in the neighborhood.

A discussion of the aims and intentions of the community forestry project and your assessment of relative successes or failures. You should also include a discussion of critical issues or conflicts in this community and how they are being managed

Power Assessment

Social actors Power Interest How to apply power
Beijing dwellers Low Moderate-high Even though they lack the ownership of land and forests, they take care and appreciate trees. The residents can remove a disease or damage tree under the granted permission by the Institute of Landscape and Gardening.
Chinese government The highest Moderate-high The state government owns all lands in Beijing, including all urban forests in streets, public parks, temples, and Palace. The Beijing Forestry Bureau and Beijing Institute of Landscape and Gardening protocol regulations of urban forests unofficially. Subsequently, they can request the approval by the People's Congress. Thus, the state government is the final driver of all laws and regulations.
Beijing Forestry Bureau Very high The highest The Beijing Forestry Bureau has rights to approve the regulations of Beijing urban forests. the government organization declared that the trees which are "taller than a building," or over 100-year-old cannot be removed.
City Government's Municipal Gardening and Landscape Administration Moderate-high High City Government's Municipal Gardening and Landscape Administration has right to judge whether the trees should be moved. For instance, this administration agrees that fewer than 10 trees in one location are to be removed.
The planting bureaus Moderate-high Moderate-high (Very high especially in their manipulated regions The bureaus take control of tree maintenance. However, the removal, cutting, and pruning of trees must be permitted by the city's Central Planting Office, who obtain the advice from the Beijing Institute of Landscape and Gardening[8].
Citizens from other cities The lowest The lowest They can monitor and give feedback about the management of urban forests to the administration listed above

Recommendations

  • To plant more trees in Beijing(the current quantity of trees is still too small to provide significant air pollution removal).

In China, the primary obstacle to urban forest's development is the insufficient funds, due to these forests cannot appeal to the private companies to invest under low financial returns directly. Based on this fact, Shanghai took the leading role to solve the restriction by providing the private companies with financial support to invest urban forests in Shanghai. The successful approach can also be introduced to Beijing. Beijing municipal government could proposal corresponding policies to offer compensation to the planting companies in Beijing to establish more urban forests[5].

  • To improve carbon sequestration and absorb more air pollutants in Beijing

Wu et.al suggest to mix up shade-intolerant species, semi-shade tolerant species and shade-tolerant trees in the common growing places. The existing species composition in Beijing is not optimal for air pollutant removal and CO2 sequestration. This is because these tree species have a short lifespan. Thus, the evergreen trees will be more suitable to alleviate air pollution, because of the longer life of leaf retention. Meanwhile, the severe environment in Beijing requires tree species which can tolerant insects, drought, air pollutants, and highly compacted soil. [9]
