“西气东输”是一项庞大的系统工程。作为“东输”的终点站也是东部经济最发达的上海市,能否“用掉”中央的供气指标(2005年30多亿立方米、2010年70亿立方米)是这项工程成败的关键。从环境角度看,天然气是清洁能源,其社会效果是显而易见的。但是从成本、资金平衡上来说,就复杂得多。从眼前几个用气领域来看,除了民用项目之外多数是“不合算”的。所以东部的有关政府部门和企业家们都在认真研究如何才能过好这一道“经济关”。用天然气代人工煤气,虽然要稍许多花一些钱,但却可换来蓝天白云。为此,要通过环境优先的教育,倡导“绿色消费”,同时向节能新技术要效益,向灵活、科学的导向性管理政策要“经济平衡”。 “West-East Gas Pipeline” is a huge systematic project. As the terminal station of the “East Transport,” it is also the most economically developed Shanghai Municipality in the eastern part of the country. Whether it can “use up” the central air supply target (3 billion cubic meters in 2005 and 7 billion cubic meters in 2010) is the success or failure of this project. The essential. From the environmental point of view, natural gas is a clean energy, its social effect is obvious. However, in terms of cost and capital balance, it is much more complex. From the point of view of several gas fields, most of them are “uneconomical” except for civilian projects. Therefore, the relevant government departments and entrepreneurs in the east are carefully studying how to manage this “economic crisis.” With artificial gas instead of natural gas, although a little more to spend some money, but it can be replaced by blue sky and white clouds. To this end, we must advocate “green consumption” through environment-based education and benefit from new energy-saving technologies. We must “balance the economy” with flexible and scientifically-oriented management policies.
