流域水电梯级开发项目群环境管理成熟度研究

A Study on Environment Management Maturity of Cascade Hydropower Development Project Group

通过从流域水体、资源、生物、社会和经济结构等方面分析梯级开发项目群累积环境影响,建立了水电梯级开发项目群环境管理成熟度二维模型。参照我国现行的建设项目管理程序,建立第1维度(梯级开发项目群环境管理指标体系):项目建议书或预可行性研究阶段、可行性研究阶段、设计阶段、施工阶段、试生产和竣工验收阶段、协调管理。同时,构建了第2维度(5级环境管理成熟度的发展等级),从低到高分别为"无序级"、"简单级"、"规范级"、"改善级"和"精益级",并对其特征重新定义。然后采用群体决策的方法对水电梯级开发项目群环境管理成熟度进行评价,利用四象限分析法对成熟度等级进行提升。分析结果表明,提升梯级开发项目群环境管理成熟度水平应对第Ⅱ象限指标重点改进,同时注意保持第Ⅰ象限水平。最后通过算例对该模型进行了验证。

A 2-deimensional environment management model is established by comprehensively analyzing the cumulative environment impacts of the cascade hydropower development project group from a series of factors such as water body,resources,biology,society and economy.Based on the current construction project management procedures in China,the first dimension（environment management evaluation system） includes the project proposal or pre-feasibility study phase,feasibility study phase,design phase,construction phase,trial production and completion acceptance phase,and cooperation management.At the same time,the second dimension（5 levels environment management maturity development model） is established,which includes ＂disorder level＂,＂simple level＂,＂standard level＂,＂improvement level＂,and ＂lean level＂ from low to high,with the characteristics of each level being redefined.Group decision method is utilized to evaluate the environment management maturity of the cascade hydropower development project group and the four-quadrant analysis is made to improve the environment management maturity.Results from the analyses indicate that for the purpose to improve the environment management maturity,the key improvement should be made in the second quadrant,while the first quadrant level should be maintained at the same time.A case study is made to verify the model.
