Brief Introduction of the Project 3.1 Basic Information of the Project This Expressway starts at Luohandong of Jingchuan County and ends at Shibalipu of Dingxi City to the northeast, passing through Jingchuan County, Pingliang City, Jingning County, Huining County and Dingxi City, with total length of 231.056km. 3.2 Brief Introduction of Natural Environment 3.2.1 Eco-environment 4 Environmental Monitoring Center of Gansu Province Luohandong~Dingxi Expressway Environmental Monitor Report From east to west, the proposed expressway passes by valley area of Jinghe River at east of Liupan Mountain, forestry area of Kongtong Mountain and loess plateau area at west of Liupan Mountain. The Jinghe River, which categories agricultural type, is distributed mostly the irrigated land; Kongtong Mountain, which situated at low mountainous area of Liupan Mount, belongs to natural ecologic type and is suitable for growth of trees and multiplying of wild animals; the loess plateau, covered by loess largely, on which sparsely grows vegetations but some herbage vegetables, has potential in danger of soil erosion due to the relatively fragile ecology. 3.2.2 Water System From east to west, the route passes Jinghe River, Dongxia Reservoir, Hulu River, Gouwa River, Zuli River and Zu River. Liupan Mountain is the dividing ridge of water system in this district. The rivers in east part belong to Jinghe River and those in west part belong to Weihe River. Jinghe River is confluent with Weihe River, which belongs to the secondary tributary of Yellow River, and is an important tributary of Weihe River. 3.2.3 Soil Types, Animals and Vegetables Jingchuan County and Kongtong District are mostly covered with loessal soil. Soil erosion can be categorized into loess plateau ravine area, loess hilly ravine area and gully area, which is mainly due to water power and identified as light corroding degree. Huining County and Dingxi District are mostly covered with grey cinnamon soil, heilu soil and loessal soil. The route is traveling through a loess hilly ravine area, with large hypsography, some sections are passing through relatively flat terrace. Jingchuan County, where the weather belongs to continental climate, has no large scaled natural forest and grass. Trees there include poplar, acacia, paulownia, stink bug, elm and spine date etc. Kongtong District, where the weather belongs to wind continental climate, has 3970 thousand mu forestry land, in which the forestry coverage rate reaches 17.98%. Forestry holds an advantageous position in the province. There are over 1000 species of vegetations including some 100 types of economic plants and 5 Environmental Monitoring Center of Gansu Province Luohandong~Dingxi Expressway Environmental Monitor Report medicinal vegetations such as sea buckthorn and liquorice, and 243 species of wild animals. The aquatic productions are mainly fresh water fish and soft-shelled turtle. Nature protection area of Kongtong mountain, covered by forestry taking over 70% of the total area, belongs to provincial protection areas. There are more than 1000 species of vegetations, 32 kinds of forestation trees, approximate 30 kinds of vegetations for raising and grazing such as vegetations in pea and standing grain families. There are 243 kinds of vertebrate belonging to 25 orders, 65 families. According to the inventory of wild protection animals released in 1989, there are totally 13 species national protection animals, in which 3 species are class I and 10 species are class II protection animals. There are plenty of insects there. By primary investigation, there are 907 kinds of insects belonging to 16 orders, 107 families and 454 genuses. Jingning County, Huining County and Anding District, in which vegetation there include natural vegetation and man-made vegetation. Natural vegetations are mainly herbage with sparse and low fraction of coverage. Man-made vegetations are formed by tree and grass planting. There is only 330 acre natural shrub on Tiemu Mountain in Huining County. Animals mainly include: wolf, fox, sheep and hare etc. 3.2.4 Weather The west of Liupan Mountain is located at sub dry area of mid temperate zone, and that at east of Liupan Mountain belongs to sub humid area of south temperate zone.

    Palaeontologia Electronica palaeo-electronica.org “Gazella” (Mammalia: Bovidae) from the late Miocene Qingyang area, Gansu, China Yikun Li, Qinqin Shi, Shaokun Chen, and Tao Deng ABSTRACT The rich collection from the late Miocene sediments from the Qingyang area, Gansu, China was discovered by E. Licent in the 1920s, and previous studies focused on the equids and hyaenids whereas little attention was given to the accompanying bovid material. The collection of Bovidae dug up from the Qingyang area and pre- served at Musée Hoangho Paiho, Tianjin, China, is dominated by “Gazella”. We describe and identify two species: “Gazella” paotehensis and “G.” dorcadoides. The nomenclatural issues surrounding those two species of gazelles are reviewed in this paper, and although the questionable mandible illustrated by Teilhard de Chardin and Young in 1931 may be excluded from “G.” paotehensis metrically and morphologically, the species is still considered valid. The subcomplete cranium M 3956, kept at Uppsala Universitet Evolutionsmuseet and studied by B. Bohlin, is selected here as the neotype of “G.” paotehensis, and emended diagnoses are given. Based on previous studies and insights from new material from the Qingyang area, we provide a table summarizing diagnostic morphological characters of “G.” paotehensis and “G.” dorcadoides. Yikun Li.

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.

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.

However, our knowledge of green development efficiency (GDE) in Gansu province is poor. In remedy, this study, based on the panel data of 12 major cities in Gansu from 2010 to 2017, employed the super-efficient Slack-based measure (SBM) to analyze and evaluate GDE from the input–output perspective. Furthermore, we analyzed the input redundancy and output deficiency of identified inefficient cities in 2017 and conducted spatial autocorrelation analysis of GDE of the cities under study. Results show differences in the GDE of the major cities in Gansu, with an average value of 0.985. Green development efficiency in Lanzhou, Qingyang, Jinchang, Jiuquan, and Tianshui was relatively higher than in other cities. Green development efficiency in Zhangye, Wuwei, Jiayuguan, Baiyin, Dingxi, Longnan, and Longnan was less than one due to their redundant labor and capital input and excessive pollutant emission output.

Rosen Received: 6 January 2017; Accepted: 22 April 2017; Published: 11 May 2017 Abstract: The idea of a circular economy (CE), which differs from traditional linear economy with a high consumption of natural resources and pollution, has captured much interest and attention. This paper uses a CE system of coal power and cement in Kongtong District, Pingliang City, Gansu Province, China as a case study to analyze the comprehensive effects of CE paradigm. Our simulation results, based on system dynamics (SD) modeling, infer that the transformation of manufacturing towards a CE system can prominently help coal power and cement enterprises reduce waste emission and increase economic profits. Through solid waste exchanges, a power plant can achieve over RMB 80 million of additional revenue per year at the highest level.
