从影视拍摄破坏环境看我国环评制度的不足

影视剧组被指景区环境事件凸显我国相关法律制度尤其是环境影响评价制度的缺失。文章在考察国外和我国环评制度的演变，分析我国影视拍摄活动破坏环境所折射出的环评法缺失的基础上，指出完善环评制度应纳入法规、政策环评，补充对社会人文活动的环评，明确法律责任，以及确立真实有效的公众参与制度及建立环境公益诉讼。     

普通高校的音乐教学探讨

音乐教育对每个人的素质培养具有重要作用，但长久以来音乐教育都不被学校、学生所重视，在我国高校的音乐教育才刚刚起步。作者根据自身多年的高校音乐教学经验，认为高校的音乐教育关键是编订独具特色的音乐教材、开启学生的兴趣之门、施行兼收并蓄的教学方法。     

Systematic Temporal Patterns in the Relationship Between Housing Development and Forest Bird Biodiversity

As people encroach increasingly on natural areas, one question is how this affects avian biodiversity. The answer to this is partly scale‐dependent. At broad scales, human populations and biodiversity concentrate in the same areas and are positively associated, but at local scales people and biodiversity are negatively associated with biodiversity. We investigated whether there is also a systematic temporal trend in the relationship between bird biodiversity and housing development. We used linear regression to examine associations between forest bird species richness and housing growth in the conterminous United States over 30 years. Our data sources were the North American Breeding Bird Survey and the 2000 decennial U.S. Census. In the 9 largest forested ecoregions, housing density increased continually over time. Across the conterminous United States, the association between bird species richness and housing density was positive for virtually all guilds except ground nesting birds. We found a systematic trajectory of declining bird species richness as housing increased through time. In more recently developed ecoregions, where housing density was still low, the association with bird species richness was neutral or positive. In ecoregions that were developed earlier and where housing density was highest, the association of housing density with bird species richness for most guilds was negative and grew stronger with advancing decades. We propose that in general the relationship between human settlement and biodiversity over time unfolds as a 2‐phase process. The first phase is apparently innocuous; associations are positive due to coincidence of low‐density housing with high biodiversity. The second phase is highly detrimental to biodiversity, and increases in housing density are associated with biodiversity losses. The long‐term effect on biodiversity depends on the final housing density. This general pattern can help unify our understanding of the relationship of human encroachment and biodiversity response.

环境司法专门化下的特殊环境诉讼规则

我国的环境司法处于发展初期,有关环境纠纷的司法救济程序散落在不同的部门法中。为了维护国家环境安全和公共环境利益,构建环境司法专门化势在必行,但是在特殊的环境保护法院进行专门化的环境审判过程中,出现环境诉讼保护对象的争议性、生态环境损害责任承担的特殊性等问题亟待解决,环境民事公益诉讼和生态环境损害赔偿诉讼等特殊环境诉讼规则应运而生,虽然目前还面临着一些困境,但是整体上构建环境司法体系的进程依然在不断推进。
