The proceeds of the loan would be onlent from the Government through Sichuan Province to EHDC under subsidiaryloan agree- ments with a 20-year term, includingnine years grace and the standard variable interest rate for Bank loans. The foreign exchange risk and commitmentcharges would be .,orne by EHDC. Project Objectives: The main objectivesof the project are tot (i) provide additionalgeneration capacity to the power system in Sichuan Province (3,300 HW and 17 TWh a year) in order to alleviate an acute shortage of electricity; (ii) assist in the transfer of modern power technology and in the introductionof efficientdam construction methods to reduce the prevailinglong gestationperiods of hydropower projects; (iii) contribute to further improvementsin the analysis of environmentaland eco- logical impacts of hydroelectricresource development; (iv) enhance the institutionaldevelopment of EHDC by strengtheningits organizationthrough a modern manage- ment training program and introducingprinciples of economic efficiency and pricing; and (v) provide tech- nical assistance in project design and implementation, and for the promotion of the optimal operation of the power system, prudent financialmanagement, and man- power development. Project Description: The proposed project would include: (i) preparatory works; (ii) constructionof a parabolic,double-curva- ture arch dam (240 m high) across the Yalong River together with an undergroundpowerhouse complex, a log conveyance system, and appurtenantworks and struc- tures; (iii) provision and installationof six 550-MW generatingunits and associatedequipment; (iv) reset- tlement of about 30,000 people; (v) an environmental management program and science station; (vi) consul- tant's services for engineering,procurement, manage- ofthek offlWduties. tscontents may not otherwise be disclosedwithout World ank authotization. - ii . ment of construction,and preparationof futurepower projects;(vii) studies of power pricingand power plant and reservoiroperation; and (viii)strengthening EIKDC'sorganization, technical assistance and staff training,together with relatedequipment and accesso- ries. Benefits: This very largeproject, based on renewableand nonpol- lutingcost-effective hydropower, would greatly increasethe generatingcapability of the Sichuanpower system. Accordingto economicanalyses, the projectis 40 percentless expensivethan its best hydrolthermal alternativesin meetingfuture power demand. The developmentof :he projectalso would enhanceindus- trial and agriculturalproduction in nearbyundeveloped areas. The projectwould help to improvethe subsec- tor's institutionaldevelopment, system operations, and managementand staffing. Purthermore,the projectwill avoidmining, transporting, and burningof some ten milliontons of raw coal a year in SichuanProvince vhich has the highestatmospheric pollution in China. The internaleconomic rate of returnbased on the cove- nantedtariff is about15 percent. However,if based on the willingnessto pay, this returnwould increase to 18 percent. Risks: Constructionrisks are withinreasonable limits and would be manageablewith the continuoussupervision arrangementsby foreignand Chineseconsultants who have been retainedfor the constructionphase. The consultantsare alreadyinvolved in reviewingpossible physicalrisks and proposingmeans and proceduresfor their avoidanceand mitigation.To minimizepotential risksassociated with the executionof the projectand its resettlementprogram, assurances were obtainedfrom the Governmentthat it would ensurean adequateand timelyflow of funds,and establishand maintaineffec- tive projectimplementation management.

  • Report on Domestic Animal Genetic Resources in China
    Country Report for the Preparation of the First Report on the State of the World’s Animal Genetic Resources Report on Domestic Animal Genetic Resources in China June 2003 Beijing CONTENTS Executive Summary Biological diversity is the basis for the existence and development of human society and has aroused the increasing great attention of international society. In June 1992, more than 150 countries including China had jointly signed the "Pact of Biological Diversity". Domestic animal genetic resources are an important component of biological diversity, precious resources formed through long-term evolution, and also the closest and most direct part of relation with human beings. Therefore, in order to realize a sustainable, stable and high-efficient animal production, it is of great significance to meet even higher demand for animal and poultry product varieties and quality by human society, strengthen conservation, and effective, rational and sustainable utilization of animal and poultry genetic resources. The "Report on Domestic Animal Genetic Resources in China" (hereinafter referred to as the "Report") was compiled in accordance with the requirements of the "World Status of Animal Genetic Resource " compiled by the FAO. The Ministry of Agriculture" (MOA) has attached great importance to the compilation of the Report, organized nearly 20 experts from administrative, technical extension, research institutes and universities to participate in the compilation team. In 1999, the first meeting of the compilation staff members had been held in the National Animal Husbandry and Veterinary Service, discussed on the compilation outline and division of labor in the Report compilation, and smoothly fulfilled the tasks to each of the compilers.

  • Re-Emerging Schistosomiasis in Hilly and Mountainous Areas of Sichuan, China Song Liang,A Changhong Yang,B Bo Zhong,C & Dongchuan Qiu C
    Re-emerging schistosomiasis in hilly and mountainous areas of Sichuan, China Song Liang,a Changhong Yang,b Bo Zhong,c & Dongchuan Qiu c Abstract Despite great strides in schistosomiasis control over the past several decades in Sichuan Province, China the disease has re-emerged in areas where it was previously controlled. We reviewed historical records and found that schistosomiasis had re- emerged in eight counties by the end of 2004 — seven of 21 counties with transmission control and one of 25 with transmission interruption as reported in 2001 were confirmed to have local disease transmission. The average “return time” (from control to re-emergence) was about eight years. The onset of re-emergence was commonly signalled by the occurrence of acute infections. Our survey results suggest that environmental and sociopolitical factors play an important role in re-emergence. The main challenge would be to consolidate and maintain effective control in the longer term until “real” eradication is achieved. This would be possible only by the formulation of a sustainable surveillance and control system. Keywords Schistosomiasis/epidemiology/prevention and control; China (source: MeSH, NLM).

  • Origin and Expansion of the Yunnan Shoot Borer, Tomicus Yunnanensis
    Origin and Expansion of the Yunnan Shoot Borer, Tomicus yunnanensis (Coleoptera: Scolytinae): A Mixture of Historical Natural Expansion and Contemporary Human-Mediated Relocation Jun Lu¨ 1,2., Shao-ji Hu1,2., Xue-yu Ma1,3, Jin-min Chen4, Qing-qing Li5, Hui Ye1,2* 1 Laboratory of Biological Invasion and Ecosecurity, Yunnan University, Kunming, 650091, China, 2 Yunnan Key Laboratory of International Rivers and Transboundary Eco- security, Yunnan University, Kunming, 650091, China, 3 School of Mathematics and Computer Science, Yunnan University of Nationalities, Kunming, 650031, China, 4 Laboratory for Conservation and Utilization of Bio-resources, Yunnan University, Kunming, 650091, China, 5 Life Science College, Yunnan Normal University, Kunming, 650092, China Abstract The Yunnan shoot borer, Tomicus yunnanensis, is a recently-discovered, aggressive pest of the Yunnan pine stands in southwestern China. Despite many bionomics studies and massive controlling efforts, research on its population genetics is extremely limited. The present study, aimed at investigating the origin and dispersal of this important forestry pest, analyzed the population genetic structure and demographic history using a mitochondrial cox1 gene fragment. Our results showed that T. yunnanensis most likely originated from the Central-Yunnan Altiplano, and the divergence time analysis placed the origin approximately 0.72 million-years ago. Host separation and specialization might have caused the speciation of T. yunnanensis. Genetic structure analyses identified two population groups, with six populations near the origin area forming one group and the remaining six populations from western and eastern Yunnan and southwestern Sichuan comprising the other. Divergence time analysis placed the split of the two groups at approximately 0.60 million-years ago, and haplotype phylogenetic tree, network, as well as migration rate suggested that populations of the latter group were established via a small number of individuals from the former one.

The result showed that the precipitation distribution in the area was rather uneven, with the main intra-annual distribution happening from June to September in small variation. Then, the annual runoff data collected in the four control stations of the main tributary were used for feature analysis. The result showed that the intra-annual runoff distribution in the area is not uneven, with obvious wet and dry periods and light inter-annual variation. © 2012 Published by Elsevier Ltd.

REVITALIZATION OF DUOXU: A FIRST-HAND ACCOUNT Katia Chirkova (CNRS-CRLAO) How can we revitalize a language that is unwritten and nearly extinct, a language that has no documentation record and is not officially recognized, and hence lacks any kind of institutionalized support? The chances of successfully revitalizing such a language are slim. One language that meets this dire description is Duoxu, the subject matter of this chapter. Under normal circumstances, revitalization of Duoxu would have little chance to take root. Yet, in spite of weighty objections, revitalization may be possible in the Duoxu case, albeit to a limited degree. Currently, revitalization of Duoxu is in the early stages of implementation. The encouraging lessons of Duoxu are that revitalization always remains a possibility, even under the most unfavorable conditions, and that efforts of individual community members dedicated to the cause can and do make an important difference.

This study aims to explore the structural response of the QTP’s eastern crust–mantle to the extrusion, and the basis for magnetotellurics, Crustal fluid, Apparent density the latter’s geological structure. Data on the long-period magnetotelluric sounding of cross-tectonic units and Bouguer gravity were used to determine the physical structure of the crust–mantle at the plateau’s eastern margin. The findings are as follows: (i) the apparent density structure indicates the large presence of a low-density material in the middle–lower crusts of the Songpan and Sichuan–Yunnan blocks at the QTP’s eastern margin. On the other hand, the Yangtze cratonic block (Sichuan Basin) contains a material with a significantly higher density.
