National Economy Assessment and Environmental Economic Gains and Losses Analysis of the Phase-II Project of the Third Ring Road

12.2.2.1 Environmental Economic Losses Analysis of the Phase-II Project of the Third Ring Road

Along the Nanjiang Binlu is mainly city ecological environment. The direct impact by the project construction on the environment is from the requisition of land, and changing the usage of parts of local land. The ecological economic losses resulted from the Project mainly come from the occupancy of the vegetable plot, timber land, garden plot and dry land etc. According to relative data in the Project Proposal Statement (including Pre-Feasibility Study Statement) of the Phase-II Project of the Third Ring Road of Fuzhou, and with reference to data in the Project Proposal Statement (including Pre-Feasibility Study Statement) of Fuzhou Nanjiang Binlu, the estimated ecological losses from the project is shown in Table 13.2 – 4.

⑵ Medical Losses from the Impact on Residents’ Health Along the Line by the Changes of Environmental Quality

The Project goes by Wanbian Village, Shangqi Village, Yangqi Village, Wushan Village, Wufeng Village, Aoshan Village and Duyuan Village etc. the permanent population of which is approximately 1358, to count as per one tenth of the population, i.e. 136 people are affected. The medical care costs margin between urban and rural areas is calculated as per 94.52 Yuan/person.year in the statistical yearbook (Note: the number is quoted from the Environmental Impact Report of the 2^nd Ring Road Phase III of Fuzhou).

To calculate the increased costs of the residents’ medical care by the market value method:

C=N*△E

N――Number of people affected by the change of environmental quality along the line;

△E――Margin of medical care costs between urban and rural areas (Yuan/person.year).

From the above formula, the annual cost of medical care from the impact on resident’s health along the line by the changes of environmental quality is RMB 12,854.72 Yuan.

⑶ Costs for Environmental Pollution by Noises

During the construction of the project, noises come from construction equipments, mainly the engines of shovel car, shovel loader etc. and the usage of electric saw as well; mechanical noises are mainly the thump of pile driver, the noise of the machinery excavating the earth material, the clash of material in agitator etc. Those will influence the life of the residents to some extent. But appropriate protective measures can minimize the harm.

If we adopt some noise abatement measures during the operation of the Project – installing noise-proof window or wall, the indoor noise condition will meet the relative functional requirements. In this way, costs for noise abatement are somewhat equal to the losses from noises without the noise-proof window or wall. Because of lack of specific design data for the noise-proof means in sensitive points, costs hereof will not be calculated for the moment.

12.2.2.2 Environmental Effect Analysis of the Phase-II Project of the Third Ring Road

The construction and operation of the Project will undoubtedly cause some disturbance and harm to the surrounding environment along the line. However, the adoption of environmental control measures shall ease the disturbance and harm, and to some effect shall have some positive effects on the original environment. Refer to Table 13.2 – 5 for this.

Table 13.2－5 Benefit Qualitative Analysis of Environmental Impact of the Phase-II Project of the Third Ring Road

Environmental Measurement	Environmental Benefits
Construction period environmental control measures	Prevent noises from affecting the residents; prevent surface water, ambient air from pollution; and prevent water loss and soil erosion.
Regulation if Afforestation and Temporary Ground	Beautify the landscape along the expressway; improve the local ecological environment; ameliorate the overall surroundings and prevent water loss and soil erosion
Noise Control Project	Prevent the traffic noise from constantly disturbing the sensitive points along the line
Aquatic Environment Protection Measures	Protect the water quality of surface water along the line; maintain the functions of the original water body; and protect the surface water resources.
Environmental Control and Monitor	Know the condition and change trend of the environmental quality and maintain the environmental quality along the line.

It is difficult to make quantitative analysis of some environmental effects after the implementation of the above measures. As follows are quantitative analyses of the effects after the implementation of some measures therein:

⑴ Analysis of Afforestation Benefit of the Phase-II Project of the Third Ring Road

For the afforestation within the scope of the Project, patches of green belt are used, and we plan to use grassland with color shrubs and to care with automatic sprinkling irrigation. Grassland is used for the separation strip in principle, with some shrubbery. For the 10.5m of green protective belts on the outer flanks of road, we plan to use grassland with arbor trees. From the perspective of ecology and health, afforestation has functions like oxygen producing, dust absorbing, disinfections, noise reducing, modifying microclimate etc. In consideration that it is difficult to collect the economic indexes of monetization, we hereby merely calculate the monetized benefit of the production of oxygen and carbon dioxide fixation.

According to the statements of Institute of Botany, Chinese Academy of Sciences, every square meter of herb plant produces 1.76g oxygen every day, and fixes 2.41g carbon dioxide. In this way, every square meter of vegetation produces oxygen 642.4g/a, and fixes carbon dioxide 880g/a. The afforestation area of this road is about 331,535m², and thus the monetized benefit of its oxygen production is about RMB 36,900 Yuan/a, and the monetized benefit of its carbon dioxide fixation is around RMB 37,400 Yuan/a, totaling RMB 74,300 Yuan/a.

⑵ Analysis of Benefits of Soil and Water Conservation

Benefits of soil and water conservation comprise ecological benefit, social benefit and economic benefit. For ecological benefit, via implementing the soil and water conservation program, the correction rate of water loss and soil erosion can reach 100%. Quantity of soil erosion cut down in the construction period reaches more than 98% of the new water loss and soil erosion, thus the water loss and soil erosion resulted from the project construction will be under effective control. The destroyed vegetation is restored, beneficial to the balance of the whole eco-system. In addition, the execution of the program will stop the earth condition within the project area from deteriorating, reduce the loss of organic matters like nitrogen and phosphor as well as the running off of inorganic salt, and contribute positively to the improvement of the local ecological environment and agricultural production conditions.

In terms of social benefit, the implementation of water and soil conservation program to a large extent stimulates the water and soil maintenance of the local construction project.

As for economic benefit, carrying on the water and soil conservation program effectively controls the water loss and soil erosion, reduces the mud and sand silting up in field and pound, decreases natural disasters and thus brings economic benefit indirectly.

12.2.3 A Brief Summary of Environmental Economic Gains and Losses Analysis of the Phase-II Project of the Third Ring Road

The construction of the 3^rd Ring Road project plays an important role in improving the traffic condition of Nantaidao Island, promoting the development and construction of Nantaidao Island and enhancing the comprehensive traffic capacity of city roads in Fuzhou. Meantime, it brings enormous economic and social benefits. Compared with the losses from environmental pollution, its social benefit is still considerable.
