考慮環(huán)境承載力的G202明水至青岡段路線(xiàn)方案研究
[Abstract]:Hei Da Highway (G202) is an important economic trunk line crossing the north and south of Heilongjiang Province. The highway is oriented to improve the networking level of the highway network in the region and to realize the horizontal connection between the regions and the rapid connection between counties and cities in the region. With the continuous upgrading and upgrading of the regional road network and the continuous growth of traffic volume, the G202 Mingshui to Qinggang section has many current road diseases, serious mixed traffic, low capacity and so on. It is also a state-level poor county, Baiquan and Mingshui. The main communication channels such as Qinggang have become the bottleneck in the regional road network which affects the function of the national trunk road and reduces the overall function of the national highway network in Heilongjiang Province. Therefore, the extension project of G202 from Mingshui to Qinggang plays an important role in improving the function of Heilongjiang National Highway Network, meeting the demand of transportation development, improving the traffic environment in the concentrated and connected areas of Heilongjiang Province, and promoting the development of regional economy. This paper analyzes the present situation and development trend of social economy and transportation in the affected area from Mingshui to Qinggang section of G202 reconstruction and extension project. By combining qualitative and quantitative methods, the population and gross domestic product (GDP) of the affected area are predicted. On the basis of traffic survey and considering the influence of induced traffic volume and urban traffic volume, the annual traffic volume in the future from Mingshui to Qinggang section of G202 reconstruction and extension project is predicted by using the four-stage method. Based on the prediction of traffic volume, considering the function, route direction, regional planning and other factors of the project, the technical standard for the section from Mingshui to Qinggang of the G202 reconstruction and extension project is drawn up, and the adaptability of its traffic capacity is analyzed. Combined with the influence of ecological environment factors on highway route selection, several route options for the section from Mingshui to Qinggang of G202 reconstruction and extension project are proposed. This paper analyzes the influence of highway construction on the ecological environment system along the route, uses the idea of pressure-state-response evaluation model for reference, and combines the actual situation of distribution of natural resources along the section between Mingshui and Qinggang of G202 reconstruction and extension project, and so on. The evaluation index of the environmental carrying capacity of the route scheme from Mingshui to Qinggang section of the G202 reconstruction and extension project is selected, and the quantitative classification method of the evaluation index is constructed. The weight of each evaluation index is determined by using the expert scoring method, and the evaluation index of the environmental carrying capacity of each alternative route scheme from Mingshui to Qinggang section of the G202 reconstruction and extension project is calculated. From this, the optimal route selection scheme of Mingshui to Qinggang section of G 202 reconstruction and extension project is determined.
