中文摘要：

环境信息公开是国际上公认的新一代环境治理手段,也是我国建设＂阳光政府＂的基本要求.在《环境信息公开办法》实施2 a后,针对31个省级、5个计划单列市和27个省会城市环境保护局落实环境信息公开的制度和行动进行调查分析,通过资料调查、实际公开申请和深入访谈,全面评估政府环境信息公开办法实施的有效性,以期为该办法的进一步完善提供政策建议.结果表明,尽管各级环境保护局公开的环境信息还不够全面、及时、有效,但是政府环境信息公开总体状况已经有了较大进步.目前环境信息公开还存在地区不平衡,而缺乏强制力,信息公开法规相应条款规定模糊,程序和责任不明确是导致环境信息公开不力的重要原因.

英文摘要：

Environmental information disclosure is seen as a creative approach in environmental governance worldwide.Environmental Information Disclosure Decree 2008（EIDD） was regarded as a milestone of right-to-know and public participation in environmental protection in China.Environmental information disclosure can improve the intercommunication between the government and public,and also speed up the transition from conventional government-dominated environmental regulation to a more transparent and modern environmental governance system in China.Aiming to explore the effectiveness of EIDD implementation by environmental agencies,this study conducted the website interviews,the practical information disclosure requests,and telephone interviews with officers from environmental agencies in 31 provinces,5 cities with independent budgetary status,and 27 provincial capital cities in 2010.It is concluded that the implementation of the Environmental Information Disclosure system has been improving over past two years but still far from being widespread,full and effective.The lack of enforcement and the ambiguity of some clauses in EIDD give environmental agencies great discretion to avoid disclosure and discourage enforcement of environmental information disclosure.
