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。     

"马房窝矿区环境污染事件"整顿见成果

2005年5月24日，国务院副总理曾培炎在四川省人民政府“关于广元市朝天区马房窝金矿污染问题调查情况的报告”上批示：环保总局要加强这方面典型经验的总结宣传，同时也要对执法不力的案件予以通报，促进各地环保工作依法有序进行。曾培炎的批示。是对广元市马房窝矿区整顿成果的充分肯定，同时也为历时半年、在全国产生重大影响的“马房窝矿区环境污染事件”的查处画上了一个阶段性的句号。[编者按]     

Total nitrogen and community turnover determine phosphorus use efficiency of phytoplankton along nutrient gradients in plateau lakes

Numerous studies support that biodiversity predict most to ecosystem functioning, but whether other factors display a more significant direct impact on ecosystem functioning than biodiversity remains to be studied. We investigated 398 samples of the phytoplankton phosphorus resource use efficiency (RUE_P = chlorophyll-a concentration/dissolved phosphate) across two seasons in nine plateau lakes in Yunnan Province, China. We identified the main contributors to phytoplankton RUE_P and analyzed their potential influences on RUE_P at different lake trophic states. The results showed that total nitrogen (TN) contributed the most to RUE_P among the nine lakes, whereas community turnover (measured as community dissimilarity) explained the most to RUE_P variation across the two seasons. Moreover, TN also influenced RUE_P by affecting biodiversity. Species richness (SR), functional attribute diversity (FAD2), and dendrogram-based functional diversity (FDc) were positively correlated with RUE_P in both seasons, while evenness was negatively correlated with RUE_P at the end of the rainy season. We also found that the effects of biodiversity and turnover on RUE_P depended on the lake trophic states. SR and FAD2 were positively correlated with RUE_P in all three trophic states. Evenness showed a negative correlation with RUE_P at the eutrophic and oligotrophic levels, but a positive correlation at the mesotrophic level. Turnover had a negative influence on RUE_P at the eutrophic level, but a positive influence at the mesotrophic and oligotrophic levels. Overall, our results suggested that multiple factors and nutrient states need to be considered when the ecosystem functioning predictors and the biodiversity-ecosystem functioning relationships are investigated.
