The exploitation and utilization of water resources affects environmental development and quality. In the early 1970's water resource in Hai He and Luan He drainage basins was exploited and utilized very greatly, once the natural environment was changed enormously. In the past 35 years, the total storage of new reservoirs was 25.9 billion cubic meters, and areas of new agricultural irrigation was 100 million mu, at the same time questions of flood control and water supply in cities, industrial and mining...

The exploitation and utilization of water resources affects environmental development and quality. In the early 1970's water resource in Hai He and Luan He drainage basins was exploited and utilized very greatly, once the natural environment was changed enormously. In the past 35 years, the total storage of new reservoirs was 25.9 billion cubic meters, and areas of new agricultural irrigation was 100 million mu, at the same time questions of flood control and water supply in cities, industrial and mining areas were partly solved, About 10.17 million mu of saline-alkali soil were improved and 23 million mu of low-lying and frequently flooded land were treated in a comprehensive way The drainage conditions in the plain of China were improved and soil has been changed into drab soil. The distribution of water resources in time and space varied greatly. The average annual discharge to the sea has been decreased half as much as the amount of 21 billion cubic meters in 1965 Utilizing ratio of water resources increased from 23% in the 1950' s to 59% in the 1970's. Annual extraction of groundwater amounted to 17.8 billion cubic meters, Groundwater levels went down and infiltration of precipitation increased. The utilizable and effective water resources that changed from evaporation of groundwater by some rational ways amounted annually to about 2 bilion cubic meters per year. The changes in the elements of water balance gave rise to harmful changes in environment, the main aspects being as follows.( 1 ) Natural water area of river and lakes greatly decreased, and aquatic products and their quality were also decreased due to water pollution and construction of sluice gates.2 ) As drainge of waste water increased, the quality of surface water and ground water deteriorated. The most serious conditions were in the Long Yang He. Generally, the water quality of the first flood each year is very poor.( 3 ) The variation of runoff of rivers often gave rise to siltation of resar-voirs, river courses and estuaries.( 4 ) Exploitation of groundwater in depth made groundwater levels decrease greatly over large area and cause surface subsidence. For instance, the area of land subsidence in Tianjing was 2,308 square km and the highest subsidence was 2.04m. In some areas, deep groundwater contains heavy fluoride and alkali materals, having effects on human health, on soil and plant.( 5 ) Due to decrease of discharge in some rivers, shipping was reduced, indirectly affecting environmental quality.The main reason for harmful impacts on environment is the shortage of water resources. The water transfer from south to north is a strategic measure to solve questions of environmental water conservancy When we consider water supply to cities, industry and agriculture, we must simultaneously consider water supply for fishery, shipping, treatment of siltaion, protection of water quality and tourism We must prevent water pollution and do well for management of environmental water conservancy and assessment of environmental impacts.

This paper summarizes the major environmental problems associated with the development of economy and the exploitation of natural resources in Guangxi Autonomous Region and discusses the origin and development tendency of these problems.Besides, the strategic countermeasures for controlling them are also analyzed. The major environmental problems in Guangxi are determined to be the serious air pollution in urban areas and the high frequency of occurrence of acid rain.These problems have become more and more severe in the past a few years.In addition, the organic pollution and over exploitation of groundwater, the general increase of environmental noise in cities and the damage of ecological environment are also pressing.The major causes for above environmental problems include: 1 ) Great and concentrated drainage of waste water; 2) Low treatment ratio of waste water and low ratio of those up to the standards over the total treated waste wateri 3 ) Unfavorable environmental factors.In the meantime, insufficient investment in environmental protection, ineffective environmental management and the low utilization ratio of natural resources and energy resources have aggravated the environmental problems.The author suggests to practice such an environmental strategy that making the focal point stand out and taking a policy of comprehensive prevention and treatment . The emphasis should be put on the prevention and control of the air pollution in urban areas. The main task in the period of the 7th Five-Year Plan should be to control the further development of air pollution,and that by the end of this century should be to improve the air quality to the 2nd grade state standards. The forward goals should be to readjust the structure of energy sources ?to progressively increase the ratio of hydroelectric power,while to decrease the use of coal. In the near future,to improve the quality of atmospheric environment in urban areas should be our main goal. The measures include mainly provi -ding low-sulfur high-quality coal to the residenis and increasing the gasification ratio of the coal. Moreover,strenthening environmental management and monitoring, perfecting the local environmental protection law and regulations,augmenting environmental consciousness of the whole nation are always our permanent goals.

本文概述了广西自治区经济发展和资源开发中出现的主要环境问题,发展趋势,并对其产生的原因及控制战略进行了分析.广西主要的环境问题是城市大气的严重污染及酸雨出现频率高,且呈逐年加重的趋势;地下水的有机污染和过量开采;城市环境噪声的普遍增高;生态环境的破坏等。排污强度大且集中,处理率和达标率低,加上不利的自然坏境因素,是造成环境污染的主要原因;而环境保护投资不足,环境管理跟不上,资源和能源利用率低等,促成了环境问题加重。建议采取重点突出,综合防治的环境战略,把主要力量放在解决城市大气污染的防治上。“七五”期间主要控制大气污染的进一步发展;至2000年使城市大气环境质量达到国家二级标准;把调整能源结构,逐步提高水电比例,降低煤的使用量作为远期目标;近期放在改善居民区的大气环境质量上.主要是供应居民低硫优质重煤,提高气化率等.而加强环境管理监督,完善地方环境法规,增加环境保护资金,提高全民族的环境意识,应是始终努力的目标.
