Introduction Hebei Province will seek US$ 150 million from the World Bank to develop the Hebei Urban Environmental Project, which includes water supply projects in Tangshan and Handan cities, and wastewater treatment projects in Shijiazhuang, Tangshan and Handan cities. The total investment is RMB 2,6 billion, of which US$150.0 million will come from the World Bank loan, while the rest will be raised by corresponding host cities. Table 1 summarizes the basic information of the project components.

The Hai River syst:emis experiencing serious water pollution due to large amount of wastewater discharged directly to watercourses without treatment. The water pollution control plan for the basin has been enlisted in the Comprehensive Water Pollution Control Plan for Three Rivers (Huai River, Hai River and Liao River) and Three Lakes (Chao Lake, Tai Lake and Dianchi Lake), issued by the State Environrnental Protection Administration (SEPA) of China. Based on the Circular on Strengthening Environmental Impact Assessment Management for Construction Projects Financed by International Financial Organizations (Huanjianzi [1993] No.. 324) and requirements of the 'Operational Policy 4.01: Environmental Assessment (OP4.01 )', the PMO of the Hebei Urban Environmental Project required that the sub-project host cities entrust environmental assessment institutions to compile environmental impact assessment reports for the individual sub-projects. The PMO has also entrusted the Center for Environmental Assessment (CEA) of the Chinese Research Academy of Environmental Sciences (CRAES) to compile the Environmental Impact Assessment Report of the overall Hebei Urban Environmental Project (HUEP). The Environmental Impact Assessment (EIA) reports for Tangshan urban environmental project were compiled by the CREAS, and the EIA reports for Shijiazhuang and Handan urban environmental projects are by the North China Civil Design and Research Academy (NCCDRA), in accordance with TOR for EIAs approved by State Environmental Protection Administration (SF,PA). The EIA for individual sub-projects are categorized as Class B. TORs of the overall EIA has passed technical review and approval of SEPA. The category of the overall EIA of the Prcject is determined to be Class B. The overall EIA report (draft) was compiled on the basis of the EIA reports of the individual sub-projects and submitted to the World Bank mission for reviewing in Oct. 1998. 3 The EIA report (final version) bas been approved by the SEPA in November 1999, in which significant attention was paid to the concerns of the World Bank missions.

Baseline Data Shijiazhuang City: Shijiazhuang city is the capital of Hebei Province, and one of the key industrial bases in North China with major industries in textile, construction material, coal and metallurgy. 4 The Futuo and Xiao Rivers are two major water courses near by the urban area. The Xiao River flows eastward through the south of urban and converges into Fuyang River at Aixin village site downstream of Handan city. The Xiao received municipal and industrial wastewater from the counties and cities along its course. Wastewater in Shijiazhuang urban area is almost entirely discharged into the Xiao through the Dongming channel, Ximing channel, and the master drainage channel. The Xiao has become a de facto wastewater discharge channel. Artificial channels in this area are the Shijin channel, Dongming channel, Ximing channel, Ximing channel Yuanmingcun channel and the master drainage channel, all of which are a part of the combined system. Monitoring data collected during the period of 1994A1996 show that water quality of the Xiao is not in compliance with Class V with water quality parameter of DO, CODcr,BOD 5, volatile phenol and oil. However, the concentration of heavy metals meet standards for Class V. The monitoring data collected at the section between the master drainage charnel and Shiban bridge on the Xiao River from November 1997 to March 1998 confirms this. There are four drainage systems serving urban areas, the West Bridge sewerage system, East Bridge sewerage system, Changan sewerage system, and the North drainage system of Shijin channel, none of which are completely separate system. The total length of open channels amount to 37.443 kin, and flood-proof dikes amount to 32 km. There are 20 sewage pump stations. Tangshan City Tangshan is one of the largest industrial cities in Hebei Province. The hydrologic region of TIangshanis divided into the Luan River basin, Shadou River basin and Jiyunhe Canal collective respectively. The Douhe river crosses the central area from north to south, and flows into the Bohai Bay. The main stream length of the

In this study, we investigated the transportation function of coastal ports in China from the perspective of cargo structure using a similarity coefficient. Our research considered both adjacent ports and hub ports. We found that the transportation function of some adjacent ports was very similar in terms of outbound structure (e.g., Qinhuangdao and Huanghua) and inbound structure (e.g., Huanghua and Tangshan). Ports around Bohai Bay and the port group in the Yangtze River Delta were the most competitive areas in terms of outbound and inbound structure, respectively. The major contributors to port similarity in different regions varied geographically due to the different market demands and cargo supplies. For adjacent ports, the functional convergence of inbound structure was more serious than the outbound. The convergence between hub ports was more serious than between adjacent ports in terms of both outbound and inbound structure. The average similarity coefficients displayed an increasing trend over time.

  • Beidaihe^ China: East Asian Hotspot Paul I
    Beidaihe^ China: East Asian hotspot Paul I. Holt, Graham P. Catley and David Tipling China has come a long way since 1958 when 'Sparrows [probably meaning any passerine], rats, bugs and flies' were proscribed as pests and a war declared on them. The extermination of a reputed 800,000 birds over three days in Beijing alone was apparently then followed by a plague of insects (Boswall 1986). After years of isolation and intellectual stagnation during the Cultural Revolution, China opened its doors to organised foreign tour groups in the late 1970s and to individual travellers from 1979 onwards. Whilst these initial 'pion­ eering' travellers included only a handful of birdwatchers, news of the country's ornithological riches soon spread and others were quick to follow. With a national avifauna in excess of 1,200 species, the People's Republic offers vast scope for study. Many of the species are endemic or nearly so, a majority are poorly known and a few possess an almost mythical draw for European birders. Sadly, all too many of the endemic forms are either rare or endangered. Initially, most of the recent visits by birders were via Hong Kong, and concentrated on China's mountainous southern and western regions. Inevitably, however, attention has shifted towards the coastal migration sites. Migration at one such, Beidaihe in Hebei Province, in Northeast China, had been studied and documented by a Danish scientist during the Second World War (Hemmingsen 1951; Hemmingsen & Guildal 1968). It became the focus of renewed interest after a 1985 Cambridge University expedition (Williams et al.

Received: 16 May 2018; Accepted: 11 June 2018; Published: 12 June 2018 Abstract: Design annual runoff is a classical issue in traditional univariate hydrological frequency analysis (HFA). We developed a multivariate HFA approach for designs for a study region covering the confluence of two streams. HFA relies on the assumption that probability distribution is consistent in the past, present, and future; however, it has been asserted as incorrect under an uncertain and changing environment. A change-point was detected in our study and adopted to divide runoff into two periods, with no significant trends in all subseries. The post-change design annual runoff witnessed dramatic mean value decline by about half at four frequencies (50%, 75%, 90% and 95%), which were selected in the bivariate analysis. Probability distribution models were constructed with univariate p-III distributions through Clayton, Frank, and Gumbel copulas and independence. Frank copula showed a generally better match with observations than others. The traditional approach, adding up the same-frequency results from both tributaries independently, was disproved by the systematically smaller design values in independence model than copulas and the 40% asynchronous encounter probability.

  • List 3. Headings That Need to Be Changed from the Machine- Converted Form
    LIST 3. HEADINGS THAT NEED TO BE CHANGED FROM THE MACHINE- CONVERTED FORM The data dictionary for the machine conversion of subject headings was prepared in summer 2000 based on the systematic romanization of Wade-Giles terms in existing subject headings identified as eligible for conversion before detailed examination of the headings could take place. When investigation of each heading was subsequently undertaken, it was discovered that some headings needed to be revised to forms that differed from the forms that had been given in the data dictionary. This occurred most frequently when older headings no longer conformed to current policy, or in the case of geographic headings, when conflicts were discovered using current geographic reference sources, for example, the listing of more than one river or mountain by the same name in China. Approximately 14% of the subject headings in the pinyin conversion project were revised differently than their machine- converted forms. To aid in bibliographic file maintenance, the following list of those headings is provided. In subject authority records for the revised headings, Used For references (4XX) coded Anne@ in the $w control subfield for earlier form of heading have been supplied for the data dictionary forms as well as the original forms of the headings.

  • 6. Jing-Jin-Ji Region, People's Republic of China
    6. Jing-Jin-Ji Region, People’s Republic of China Michael Lindfield, Xueyao Duan and Aijun Qiu 6.1 INTRODUCTION The Beijing–Tianjin–Hebei Region, known as the Jing-Jin-Ji Region (JJJR), is one of the most important political, economic and cultural areas in China. The Chinese government has recognized the need for improved management and development of the region and has made it a priority to integrate all the cities in the Bohai Bay rim and foster its economic development. This economy is China’s third economic growth engine, alongside the Pearl River and Yangtze River Deltas. Jing-Jin-Ji was the heart of the old industrial centres of China and has traditionally been involved in heavy industries and manufacturing. Over recent years, the region has developed significant clusters of newer industries in the automotive, electronics, petrochemical, software and aircraft sectors. Tourism is a major industry for Beijing. However, the region is experiencing many growth management problems, undermining its competitiveness, management, and sustainable development. It has not benefited as much from the more integrated approaches to development that were used in the older-established Pearl River Delta and Yangtze River Delta regions, where the results of the reforms that have taken place in China since Deng Xiaoping have been nothing less than extraordinary. The Jing-Jin-Ji Region covers the municipalities of Beijing and Tianjin and Hebei province (including 11 prefecture cities in Hebei). Beijing and Tianjin are integrated geographically with Hebei province. In 2012, the total population of the Jing-Jin-Ji Region was 107.7 million.
