The whole line has 433 grand, great and medium bridges, totally 181,788 linear meters long; there are 267 tunnels of 596.8Km long in total, including 11 tunnels longer than 10Km (totally 168Km). The track length of normal line is 819.975Km and the track length of hub and connecting lines is 180Km. Along the line there are 23 traction substations. The whole line occupies 5,218.2hm2 of land, including 3,289.7hm2 of land for permanent use and 1,928.5hm2 of land for temporary use. 42 new stations will be built and 15 stations will be modified along the whole line. Pavements with length of 1445.1Km will be built. 2 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 There are 324 sensitive points for noise and vibration control along the whole line. Besides functional replacement is needed for 115 places, noise barriers (40310m) or sound-proof windows (83120m2) will be arranged at 209 places. The total investment on noise control will be 202.433 million Yuan. 1.2 Project characteristics Lanzhou–Chongqing Railway goes through, from the north to the south, such three geomorphic units as Loess Plateau, high and medium mountains area 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 Qinling’s high and medium mountains area and mid - subtropical 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 intensity is mainly medium, but it is serious or extra serious for some sections. The erosion is mainly hydraulic erosion 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 3 Environment Monitoring Report on Newly-built Lanzhou-Chongqing Railway in 2018 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 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 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 report during the construction.

In the Sichuan province, livelihood security and social development are particularly sensitive to changes in the sloping farmland, due to the region’s large portion of hilly territory and its over-dense population. In this study, we focused on spatiotemporal change of the sloping farmland and its driving forces in the Sichuan province. Sloping farmland areas were extracted from geographic data from digital elevation model (DEM) and land use maps, and the driving forces of the spatiotemporal change were analyzed using a principal component analysis (PCA). The results indicated that, from 2000 to 2015, sloping farmland decreased by 3263 km2 in the Sichuan province. The area of gently sloping farmland (<10◦) decreased dramatically by 1467 km2, especially in the capital city, Chengdu, and its surrounding areas.

  • Lithofacies Palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China
    Journal of Palaeogeography 2014, 3(4): 384-409 DOI: 10.3724/SP.J.1261.2014.00063 Lithofacies palaeogeography and sedimentology Lithofacies palaeogeography of the Late Permian Wujiaping Age in the Middle and Upper Yangtze Region, China Jin-Xiong Luo*, You-Bin He, Rui Wang School of Geosciences, Yangtze University, Wuhan 430100, China Abstract The lithofacies palaeogeography of the Late Permian Wujiaping Age in Middle and Upper Yangtze Region was studied based on petrography and the “single factor analysis and multifactor comprehensive mapping” method. The Upper Permian Wujiaping Stage in the Middle and Upper Yangtze Region is mainly composed of carbonate rocks and clastic rocks, with lesser amounts of siliceous rocks, pyroclastic rocks, volcanic rocks and coal. The rocks can be divided into three types, including clastic rock, clastic rock-limestone and lime- stone-siliceous rock, and four fundamental ecological types and four fossil assemblages are recognized in the Wujiaping Stage. Based on a petrological and palaeoecological study, six single factors were selected, namely, thickness (m), content (%) of marine rocks, content (%) of shallow water carbonate rocks, content (%) of biograins with limemud, content (%) of thin- bedded siliceous rocks and content (%) of deep water sedimentary rocks. Six single factors maps of the Wujiaping Stage and one lithofacies palaeogeography map of the Wujiaping Age were composed. Palaeogeographic units from west to east include an eroded area, an alluvial plain, a clastic rock platform, a carbonate rock platform where biocrowds developed, a slope and a basin. In addition, a clastic rock platform exists in the southeast of the study area. Hydro- carbon source rock and reservoir conditions were preliminarily analyzed based on lithofacies palaeogeography.

Abstract: Rural clean heating project (RCHP) in China aims to increase flexibility in the rural energy system, enhance the integration of renewable energy and distributed generation, and reduce environmental impact. While RCHP-enabling routes have been studied from a technical perspective, the economic, ecological, regulatory, and policy dimensions of RCHP are yet to be analysed in depth, especially in the underdeveloped areas in China. This paper discusses RCHP in rural Gansu using a multi-dimensional approach. We first focus on the current issues and challenges of RCHP in rural Gansu. Then the RCHP-enabling areas are briefly zoned into six typical regions based on the resource distribution in Gansu Province, and a matching framework of RCHP is recommended. Then we focus on the economics and sustainability of RCHP-enabling technologies. Based on the medium-term assessment of RCHP in the demonstration provinces, various technical schemes and routes are analysed and compared in order to determine which should be adopted in rural Gansu.

  • Study on Urban Efficiency Measurement and Spatiotemporal
    sustainability Article Study on Urban Efficiency Measurement and Spatiotemporal Evolution of Cities in Northwest China Based on the DEA–Malmquist Model Jun Yin and Qingmei Tan * College of Economics and Management, Nanjing University of Aeronautics and Astronautics, Nanjing 211106, China; [email protected] * Correspondence: [email protected] Received: 18 November 2018; Accepted: 12 January 2019; Published: 15 January 2019 Abstract: Urban efficiency can effectively measure the management and allocation level of urban factor inputs. Based on the data of 30 prefecture-level cities in Northwest China from 2006 to 2015, urban efficiency is measured by data envelopment analysis (DEA). Then the spatiotemporal evolution rule is identified by Malmquist model. The results illustrate that the overall average urban efficiency of cities in Northwest China each year from 2006 to 2015 was at the low level. Only Jiayuguan, Yulin, Yan’an, and Karamay reached the high average urban efficiency, while Dingxi, Pingliang, Guyuan, Shangluo, Tianshui, Longnan, and Baiyin were at the inefficient level. Most cities in Northwest China were still in the “growing” stage of increasing returns to scale. The scale of urban investment was relatively insufficient, and economies of scale had not yet formed. Cities with decreasing returns to scale were mainly distributed in the capital cities and the central and sub-central cities of Guanzhong-Tianshui Economic Zone with relatively abundant urban resources and capital. Cities with constant returns to scale were mainly distributed in four cities including Yan’an, Yulin, Jiayuguan, and Karamay with high efficiency. The overall comprehensive efficiency, technical efficiency, and scale efficiency of cities in Northwest China were not only low, but also showing a downward trend.
