| 摘 要： | 以流域为单元进行社会经济发展与环境保护调控,是实现可持续发展的有效途径,因此以流域为单元开展社会经济发展与水环境变化相互作用的研究方兴未艾。运用多元线性回归分析,选取社会经济指标(第一产业生产总值、第二产业生产总值、年末总人口)为自变量,水质指标(化学需氧量、氨氮浓度)为因变量定量研究了2001—2010年辽河水环境演变与流域内社会经济发展之间的关系;并采用经济增长指标(人均GDP)、水环境指标(化学需氧量、氨氮浓度)作为模型中指标,进行了环境库兹涅茨曲线模拟与分析。根据研究结果推断:第二产业生产总值、人口是影响辽河水质化学需氧量浓度变化的社会经济重要因素,影响氨氮浓度变化的因素众多;辽河流域经济增长与水环境之间的关系曲线不完全符合典型的库兹涅茨曲线特征。随着经济快速增长,应在开展工业点源污染达标排放控制的同时,加强农业面源污染的治理力度。

| Abstract: | Taking a river watershed as a unit to regulate socio-economic development and environmental protection, is an effective way to achieve sustainable development. And therefore it is unfolding to carry out a study of the interaction between the socio-economic development and the changes in the water environment in a river watershed. Using multiple linear regression analysis, selecting socio-economic indicators (the primary industry GDP, the secondary industry GDP, the end of the total population of one year) as the independent variable, water quality indicators (concentration of CODMn and NH3-N) as the dependent variable, quantitative research of the relationship between the socio-economic development and water environment was carried out from 2001 to 2010 in Liaohe River watershed. And the environmental Kuznets curve was simulated by taking water environment indicators (concentration of CODMn and NH3-N) and economic growth indicators (per capita GDP) as indicators. And the results showed that the secondary industry GDP, population are important factors to affect the changes of the concentration of CODMn, and there are many factors to influence NH3-N concentration. And relationship curve between the economic growth and water environment is not fully consistent with the typical Kuznets Curve in Liaohe River Watershed. Accompanied rapid economic growth, industrial point source pollution discharge control should carry out, and agricultural nonpoint source pollution control efforts should be strengthened at the same time. |
