珠海市城市化进程中环境效应分析

Analysis of the environment effect on Zhuhai′s urbanization

选用废气、SO2、废水、工业废水等排放量和工业固废物产生量作为珠海市环境破坏因子，人均GDP为经济增长指标，采用Excel和SPSS软件对珠海市1990～2003年统计数据诸因素进行相关性分析，用环境库兹涅茨曲线进行回归分析．结果表明，珠海市的环境质量与经济增长之间的关系符合环境库兹涅茨曲线趋势，呈现倒“U”型．分析结果还表明了环境的改善并不会随着经济水平的提高而自动发生，环境与经济的协调发展需要继续改善经济结构，增加环保投入．

Kuzents＇ curve shows that environment is inevitably exacerbated in some extent as the economy grows. But when GDP per capita arrives at certain point, the development of economy is benificial environment. With the software of EXCEL and SPSS, the correlativity between GDP per capita and environment pollution factors is studied on the basis of statistics data from from 1990 to 2003 of Zhuhai. The GDP per capita as independent and environment pollution factors such as exhaust air discharge, S02, wastewater discharge, industrial wastewater discharge, industrial solid waste production is used as dependent. The quadratic regression results of environment indicators with GDP per capita of Zhuhai show that the effect between environment quality and economy growth is consonant with Kuzents＇curve and that the environment is not improved necessarily as economy speeds up. It is necessary to modify economy structure and increase invest in environment protection to keep environment and economy improving harmonically.
