1.2 Characteristics of This Project

Lanzhou – Chongqing Railway goes through, from the north to the south, such three geomorphic units as Loess Plateau, high and medium mountains of the Qinling Mountains and low mountains and hills area in Sichuan Basin and spans such four climate zones as the arid climate area in the mid-temperate zone of Loess Plateau, sub-humid climate zone of mid-temperate zone, North Asia tropical humid zone in the high and medium mountains in the Qinling Mountains and Middle Asia tropical humid zone in Sichuan Basin. Along Lanzhou-Chongqing Railway, there are many kinds of vegetation. The horizontal and vertical distribution of vegetation is obvious. Roughly, Qinling Mountains is taken as the dividing line. The biodiversity in Yangtze River Basin on the south of Qinling Mountains is higher than that in the Yellow River basin. The land erosion area in the drainage area of the Yellow River basin, in which the railway goes, is big, and the erosion extent is mainly medium, but it is serious or extra serious for some sections. The erosion variety takes the water conservancy erosion as the main and such gravity erosions as mud-stone flow and landslide etc. often occur in the earth and stone and mountain area. The ecological environment along the line sections in the drainage area of the Yangtze River is comparatively better, and, basically no obvious erosion or only light erosion can be seen for soil erosion. Along the line, there are rich resources of wildings as well as cultural relics, which are mainly distributed in the natural reservation zones, the famous scenery spots and historical relics, forest parks, and the cultural relic protection zones and are greatly affected by human activities. Emphasized protection targets: Ancient Xiaguanying relic, ancient Shannashuzha relic, Yuhe Natural Reserve of Gansu Province, Sichuan Maozhai Nature Reserve, Wetlands Natural

3 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2017

Reserve of Jialing River Source, Myxiocyprinus Asiaticus of Natural Reserve, etc.; Ecological environmental protection main targets: cultural heritage, the vegetation, rare animal and land resources, etc. along the line. It is the important contents for environment monitoring work to strictly implement the relevant state laws and regulations, abide by the requirements and replies from the relevant state and local departments as well as various levels of departments for cultural relics, water conservation, forestry, environmental protection and fishing administration etc. and strictly execute the various measures in the EIA (environmental impact assessment) report during the construction. The big rivers spanned by the railway line are the Yellow River, the Wei River, the , the Bailong River, the Jialing River, the Fu River and the Qu River etc. Since high subgrads will be replaced by bridges for this project, there is much bridge construction engineering for the whole line. The land occupation and disposed earth from the sub-grade for non-river-crossing bridges has certain impacts on the ecological environment along the line, so has the construction of river-crossing bridges on the water quality and hydro bios of rivers. The total volume of the cubic meter of earth and stone along this line is large and the volume of disposed earth is far bigger than the volume of taken earth, so it is vitally important to further optimize the allotment of cubic meter of earth and stone, reduce the earth-taking and earth-disposing volumes and occupied land areas, take such preventive measures as land reclamation and afforestation etc. in accordance with the land reclamation program and design for temporary land use and prevent the generation of new land erosion.

1.3 Environment Monitoring

The environment monitoring is to supervise and inspect the execution of environmental protection measures during construction of the project on the basis of the design and environment evaluation report of this project and to affirm the achievements, find out existing problems and give suggestions on

4 Environment Monitoring Report on New Lanzhou-Chongqing Railway Development Project in 2017 countermeasures. By strengthening process control, the environmental monitoring ensures to carry out “Three-simultaneousness” system strictly. It reflects the dynamic implementation status of environmental protection work on the construction site during the construction activities so as to confirm whether the relevant rules and regulations for environmental protection have been satisfied and whether the requirements from Ministry of Railways and Asian

Development Bank have been met. Key points that attention should be paid to during environment monitoring include:  Whether the environmental impact during construction is consistent with the environmental problem put forward in the environmental impact assessment report;  The accomplishment of environmental protection measures given in environmental impact assessment report;  Identify and find out any unexpected environmental problems and put forward recommended solutions; The environmental monitoring of Lanzhou-Chongqing Railway is taken by Beijing OASIS Environmental Protection Technology Co., Ltd. The service range is the main line of Lanzhou-Chongqing Railway from Lanzhou to Beibei North, which is 818.71 km long in total. The cycle of environment monitoring work is the construction period of the whole line and within the two years after being put into operation after completion. For every half year of the construction period and for every year of the two years after completion, one environment monitoring report (in both English and Chinese) should be prepared by OASIS Company on the basis of the on-site survey and collected monitored data and submitted to Materials Department of China Railway Corporation, Lanzhou-Chongqing Railway Co., Ltd., Development Planning Department of the Ministry of Railways and Asian Development Bank. The monitoring report should contain the following content:  Impacts on the ecological environment imposed by construction of stations,
