R. China September, 1999 Assessment Institution: GuangxiEnvironmental Protection Scientific Research Institute Assessment Certificate: No. 0949 Public Disclosure Authorized Director: Wang Censheng Project Chief: Yu Wanli Deputy Project Chief: Gan Zhengqi I Members of Project Group: Niu Ling, Fan Zhenhui, Gu Zhanqi, Chen Bei Preface The assessed project herewith belongs to the World Bank Aided project under the Highway Network Improvement Program in poverty-stricken area of Shuiren-Nanning Highway project, it consists of ten sub-projects of road improvement. The target of the project construction is to improve the transportation conditions of the poor area nearby the main project, to promote local economic development and upgrade the comprehensive traffic capacity of the road network in this region. According to the environmental management policies for project construction of the World Bank, Guangxi Roads & Highways Bureau entrusted Guangxi Environmental Protection Scientific Research Institute with the task to compile the IEEs and EAPs in December of 1998. On this basis, our Institute conducted successively two times of field environmental investigation respectively in December of 1998 and April of 1999. In February of 1999, we finished the IEE and EAP for the seven sections including G209 Qintang - Wuli sub-project. In April of 1999, upon exchanged ideas with Guangxi CommunicationsDepartment, we made necessary adjustment, amendment and addition to this report according to the suggestions proposed by the World Bank Delegation during its preparation mission. We also added G324 Baise - Tianlin section, G323 Pingcun - Juxu section and formed a revised report. In August of 1999, the World Bank delegation undertook detailed examiniation of the revised report and put forward written suggestion for revision. According to the revison suggestion, we again made necessary adjustment and revision, thus this Report is done. I Contents PART ONE INITIAL ENVIRONMENTAL EVALUATION (IEE) 0 1.

Two sub-projects of Mashan connecting road and Dahua connecting road are included in the range of environmental assessment of the main project - Shuiren-Nanning Highway Project. Detail environmental assessment have been done in this regard (refer to the environmental assessment report of Shuiren-Nanning Highway project), so we do not undertake further assessment herewith. 1.1.3 Progress arrangement of project implementation The project plans to be implemented during 2000-2003. Respective implementing timetable are referred to Table 1- 1. I I 2 Brief Introduction to the Environment 2.1 Description of natural environment 2.1.1 Local topography, geomorphy and soil types of project sites Qintang - Wuli section, Wuli - Heng county section, Shinan - Guigang section are located in the southeast of Guangxi, the geomorphy mainly belongs to plains and hills. Wujia - Hepu section, Changle - Hepu county section are located in the south of Guangxi, the geomorphy belongs to alluvial plain and micro hillock around 30 km away from the Beibu Gulf. Jiuxu- Pingcun, Baise-Tianlin are located in the west of Guangxi, the formnerbelongs to karst topography showing continuos mountains and embedded with various sizes of round or honeycomb low- laying land; the latter are mainly hills and basins. Except for Pingcun-Jiuxu section, the eight sections are mostly of twisted roads of many curves and big slopes. Baise-Tianlin section has many small slopes, and the other six sections are mostly of smooth area but with some undulation. The districts of these sections are mainly of plains and micro hills. Details refer to Table 2-1 2.1.2 Climate The climates passed by the eight sections do not vary distinctly belonging to subtropical monsoon climate, showing long summer and short winter, adequate sunlight and rainfall, rainfall and heat of same season, long frost-free season, distinct dry and wet seasons etc. The district is also one of those districts of frequent disastrous weather. According to meteorological data of counties and cities, the summer begins from end of April and ends at mid of October nearly half a year. Winter starts from mid of January and ends at mid of February only one month. The average highest temperature is in July, and lowest in January. March and April are humid. November and December are the driest months. Typhoon mostly occurs in May - August. Meteorological data of different sections are shown in Table2-2. 2.1.3 Hydrographic conditions of various sections The places along the eight sections have adequate surface water with well-developed rivers.
