Five, land acquisition, demolition and resettlement planning

The East Line project spans Jiangsu, Shandong, Hebei and Tianjin provinces and municipalities directly under the Central Government, and the influence scope of excavation and demolition involves 4 provinces and municipalities directly under the Central Government/0/8 cities and 59 counties (districts). Because the water conveyance project mainly uses the existing river channel to expand and dig the reach that can't meet the water conveyance requirements, it mainly occupies the floodplain, and the population migration is small, so the problem of land acquisition, demolition and resettlement is relatively easy to solve.

The water conveyance channel is long, the demolition amount is relatively small, and the immigrants are scattered, mainly by the back and the nearby resettlement. The newly expanded reservoir covers a large area, but mainly uses abandoned depressions. Dongping Lake water storage project is the area with the largest number of immigrants and the largest concentration, which involves problems left over from history and has a large investment.

The first phase of the project covers a permanent area of 1.600 hm2, a temporary area of about 2670hm2, demolished houses of 1.0 1.340 m2, and about 25,300 immigrants. The static investment of compensation for land acquisition and demolition is about 2.7 billion yuan.

On the basis of the first-phase project, the second-phase project will increase the permanent land by 654.38+280,000 hm2, the temporary land by nearly 3000hm2, the house demolition by 7365.438+300,000 m2, and the immigrant population by about 654.38+830,000. Increase the compensation investment for land acquisition and demolition by about 2.8 billion yuan.

On the basis of the second phase, the third phase project will increase the permanent area by about 7730hm2, the temporary area by about 2600hm2, the house to be demolished1136,500m2, and the relocated population by about 28,400 people. Increase the compensation investment for land acquisition and demolition by about 2.4 billion yuan.

VI. Pollution Control Planning

The pollution control planning of the Eastern Route Project is divided into water conveyance trunk line planning area, water conservation planning area of Shandong and Tianjin, and water quality improvement planning area of Henan and Anhui. The main pollution control measures are five types of projects: urban sewage treatment plant construction, sewage interception and diversion, industrial structure adjustment, industrial comprehensive management and river basin comprehensive improvement project.

According to the present situation of water quality and water pollution control, the area south of the Yellow River should focus on the treatment of industrial structural pollution and domestic sewage, combine the main project with the existing river water conservancy project, and implement sewage interception and diversion and sewage reuse where conditions permit, effectively reduce the amount of sewage entering the river and control oil and agricultural non-point source pollution; Taking sewage interception and diversion as the main measure to form a clear water corridor in the north of the Yellow River can improve the regional environmental quality and realize the recycling of sewage.

In order to embody the principle of water supply after pollution control, according to the requirements of project implementation progress, pollution control is divided into two periods: 2007 and 20 10. Before 2007, pollution control projects and pollution interception and diversion projects in Shandong and Jiangsu were the main projects, and industrial control projects in Hebei were implemented at the same time; From 2008 to 2065438+00, sewage treatment plants and sewage interception and diversion projects in Hebei and Tianjin were mainly implemented, and pollution control projects in Henan and Anhui provinces were also implemented. After the implementation of the planned project, it is predicted that the water quality can reach Class III or be better than Class III water standard.

The total investment of pollution control project is 24 billion yuan, and the investment of pollution interception and diversion project is 2.49 billion yuan, including 65.438+72.5 billion yuan in the first phase and 765 million yuan in the second phase.

Seven, environmental impact analysis

The environmental impact of the eastern route project is that the advantages outweigh the disadvantages, and the adverse impact can also be improved by taking measures. After the implementation of the project, it will help improve the supply and demand conditions of water resources in the northern region and promote the sustainable development of economy and society; Conducive to improving the ecological environment of water supply areas and improving people's quality of life; It is beneficial to replenish groundwater along the line and alleviate land subsidence; Conducive to the safety of drinking water in cities and towns and improve the drinking water quality of residents in high fluorine areas; It is beneficial to improve the investment environment of water supply area and has remarkable social benefits.

After years of monitoring, testing and analysis of possible adverse environmental impacts, the following conclusions are drawn:

1. The proportion of water transfer in the East Route Project is very small, and the water transfer has little influence on the water level of the Yangtze River below the water intake, river siltation and the position of the mouth bar sand. The first phase of the project only increases the river diversion1100m3/s/s compared with the current situation, which will not aggravate the harm of salt water intrusion in the Yangtze River estuary. In the dry season of the Yangtze River, avoidance measures can be taken to avoid aggravating the salt water intrusion in the Yangtze River estuary.

2. The Huang-Huai-Hai Plain has formed a relatively perfect drainage system and accumulated rich experience in preventing soil salinization. The secondary salinization of soil in northern irrigation area can be prevented and controlled.

3. According to the experiment and water transfer practice, water transfer will not make Schistosoma japonicum spread from south to north.

4. Water transfer is beneficial to aquatic organisms in lakes along the water transfer, but has no obvious influence on aquatic organisms in the Yangtze River estuary and its adjacent waters.

VIII. Project Management

The system of "government macro-control, quasi-market operation, modern enterprise management and water users' participation" is adopted in the management of the East Line Project, which not only embodies the requirements of market economy, but also implements the principle of unified management of water resources.

(A) the establishment of South-to-North Water Diversion Project construction management agencies

The State Council organized relevant departments and provinces and municipalities directly under the Central Government to set up the South-to-North Water Transfer Project Leading Group (hereinafter referred to as the Leading Group). Implement unified leadership of the project, coordinate and solve major problems in the construction and management of the South-to-North Water Transfer Project, and guide the formulation of relevant laws, regulations, policies and management measures.

Set up a water supply company

The first phase of the project only involves Jiangsu and Shandong provinces. Jiangsu Water Supply Company and Shandong Water Supply Company can set up legal persons respectively, establish water delivery relations through water supply contracts, and manage projects and water supply in various provinces.

The management system of the second phase and beyond can be established on the basis of the above two companies, or an appropriate way can be considered according to the situation and conditions at that time. For the time being, this plan studies related issues according to the system of establishing legal persons respectively for Eastern Company and Jiangsu Water Supply Company.

Nine. Engineering quantity and investment estimation

The East Line Project consists of a series of single projects, such as water conveyance channel, pumping station, water storage lake, yellow river crossing project, pollution control project, soil and water conservation project, power supply, dispatching and operation management facilities. On the basis of a single project, water transfer schemes of different scales are formed.

X. Economic analysis

The direct benefits of the Eastern Route Project mainly include industrial water supply, agricultural water supply, waterlogging control and shipping water supply. According to the net increased water supply and comprehensive economic indicators, the benefits of the first, second and third phases of the project are 9.7 billion yuan, 654.38+0.67 billion yuan and 654.38+0.56 billion yuan respectively. The implementation of the Eastern Route Project will promote regional economic development and social progress, effectively curb the deterioration of the ecological environment and improve people's quality of life. In addition, the dredging of rivers and lakes in the Eastern Route Project will greatly improve flood control, shipping and ecological environment conditions, and the comprehensive benefits will be huge.

Through analysis, the national economic and financial indicators of the Eastern Route Project have reached or exceeded the national standards, and the project is economical and feasible.

The investment structure of the Eastern Route Project is that loans account for 45% and capital accounts for 55%. According to the principle of "capital preservation, low profit and repayment", the water price of the main project is calculated according to the conditions that the water fee will repay the loan principal and interest accounting for 20% of the project investment, and other loans will be repaid by the South-to-North Water Transfer Fund. The average water price of the first phase project is 0.26 yuan /m3, that of Jiangsu Province is 0. 17 yuan /m3, and that of Shandong Province is 0.59 yuan /m3. Through carrying capacity analysis, after the completion of the project, water users can bear the water price of such a main project.
