生态城市规划的环境影响评价研究——以哈尔滨市为例

为了促进《中华人民共和国环境影响评价法》的实施,为了把环境保护的意识渗透到生态城市规划的各项社会经济发展战略中,在生态城市规划的早期阶段充分考虑环境的影响,实现城市的可持续发展,鉴于生态城市规划在国内外都很盛行,笔者以哈尔滨市为例,针对生态城市规划环境影响评价的特点,参照宋永昌等人提出的生态城市的评价指标体系,构建了适合生态城市规划环境影响评价的方法系统,即采用适合生态城市规划环境影响评价的数学模型,对城市复合生态系统进行定量分析,该方法以层次分析法为基础,将生态综合指标分为生态系统结构、城市功能和城市协调度3个目标子系统,并在此基础上细化评价因子,通过矩阵运算确定其权重和指标数值,再根据适当的评价标准,得出评价结论。本研究运用此方法系统,对黑龙江省哈尔滨市生态城市规划进行了实证研究。通过计算分析得出,哈尔滨市生态化程度一般,并指出其在生态城市规划过程中存在的问题以及环境影响减缓对策。

Influence of Voluntary Accounting Changes Based on Impairment Provision on Enterprise Value

Based on Feltham-Ohlson Model,this paper has set up a model that enterprise net assets change with time and brings the accrual of impairment provision into it.Through an analysis of the model,the authors find the follows: In general,the realization of maximum of enterprise value has nothing to do with voluntary accounting changes based on impairment provision.Whether there are voluntary accounting changes or not,the refinancing constraints will reduce the IOS,i.e.enterprise value.On the condition of refinancing constraints,that the enterprise adopts voluntary accounting changes of reducing the accrual of impairment provision in order to meet the demand of refinancing will cause the further decline of IOS,i.e.enterprise value.
