重点矿业经济区水资源承载力评价与测度

Assessment and Measurement of Water Resources Carrying Capacity in Key Mining Economic Zone

在总结国内外水资源承载力相关研究的基础上,构建简单、可操作的评价模型,测算水资源对人口、工业、矿产资源开发和污水容纳量的承载能力。以辽宁鞍山铁矿业经济区为例进行实证研究,计算出鞍山铁矿业经济区2012年水资源对人口、工业、矿产资源开发和污水容纳的承载力,以及2002—2012年该矿业经济区水资源所能承载的最大经济规模和人口规模,并与实际值进行比较。研究结果表明:1辽宁鞍山铁矿业经济区水资源对工业和矿产资源开发的承载力已处于超载状态,对人口和污水容纳量仍在可承载的范围内;2水资源经济承载指数和人口承载指数变化趋势基本一致,但在2002年和2003年水资源人口承载指数略高于经济承载指数,同时也表明转型中的鞍山铁矿业经济区经济增长和人口规模发展趋于协调。

Based on the summary of water resources carrying capacity research at home and abroad, this paper built a simple and operational evaluation model to measure the water resources carrying capacity of the population, industry, mineral resources development and carrying capacity of sewage. Taking Anshan Iron Mining Economic Zone of Liaoning for an example, this paper calculated the carrying capacity of the population, industry, mineral resources development and sewage about Anshan Iron Mining Economic Zone in 2012, and its maximum size of the economy and population from 2002 to 2012, then compared with the actual level. The results showed that：OThe carrying capacity of industry and mineral resources development was already in overload state,but the carrying capacity of the population and sewage were still within the range. OThe trend of water resources carrying index of economic and demographic was basically the same, but in 2002 and 2003 the population carrying index was slightly higher than the economy index. It also indicated the economic growth and population size tend to be coordinate about Anshan Iron Mining Economic Zone in transitlon
