陕西关中渭北地区村镇建筑防火现状调查与分析

根据相关统计，农村地区建筑面临与城市地区同样的火灾风险。为了农村地区人民生命财产安全，预防火灾，从村镇规划及布局、消防设施及人员消防意识、户舍基本情况调查入手，对陕西关中渭北地区村镇建筑防火现状进行调查与分析。根据调查结果，发现该地区村镇建筑防火条件薄弱，与相关规范差距很大，人员消防意识淡薄，缺乏相关立法规范村镇消防责任制，相关防火规范不完善，应该引起各方对农村防火的高度重视。

Conservation Easements: Biodiversity Protection and Private Use

Abstract:  Conservation easements are one of the primary tools for conserving biodiversity on private land. Despite their increasing use, little quantitative data are available on what species and habitats conservation easements aim to protect, how much structural development they allow, or what types of land use they commonly permit. To address these knowledge gaps, we surveyed staff responsible for 119 conservation easements established by the largest nonprofit easement holder, The Nature Conservancy, between 1985 and 2004. Most easements (80%) aimed to provide core habitat to protect species or communities on-site, and nearly all were designed to reduce development. Conservation easements also allowed for a wide range of private uses, which may result in additional fragmentation and habitat disturbance. Some residential or commercial use, new structures, or subdivision of the property were permitted on 85% of sampled conservation easements. Over half (56%) allowed some additional buildings, of which 60% restricted structure size or building area. Working landscape easements with ranching, forestry, or farming made up nearly half (46%) of the easement properties sampled and were more likely than easements without these uses to be designated as buffers to enhance biodiversity in the surrounding area. Our results demonstrate the need for clear restrictions on building and subdivision in easements, research on the compatibility of private uses on easement land, and greater public understanding of the trade-offs implicit in the use of conservation easements for biodiversity conservation.     

环境准入门槛设置与指标体系构建实证

根据统筹协调、生态优先、地域差异、管理可行性等原则,从前置性和控制性两个方面,选取包括时序、空间、容量、投资规模、排放总量与强度以及资源、能源消耗标准等要素指标,建立环境准入指标体系;并以江苏省为例,根据指标门槛设置的标准和依据,进行指标门槛的定量测算。初步得到:重点企业最低投资准入、重点区域和重点污染行业环境准入指标测算值,以期为政策制定者提供可资借鉴的依据。     

联苯代谢对微生物的生长胁迫及分裂抑制

以联苯/多氯联苯降解菌株R04（Rhodococcus sp.R04）和几种模式微生物为研究对象，利用高效液相色谱、荧光显微镜、扫描电子显微镜等分析微生物在联苯及其代谢物培养条件下细胞分裂和形态的变化.结果表明联苯及其代谢产物对红球菌R04和几种模式微生物细胞的分裂有抑制作用，并对部分微生物形态有影响.与前体-联苯及其代谢产物2-羟基-6-酮基-6-苯基-2，4-己二烯酸相比，2，3-二羟基联苯对G⁺、G^-细菌，或是酵母细胞分裂都有较强的抑制和形态的改变.2，3-二羟基联苯导致R.R04和缺陷型R.R04细胞形成不完整隔膜的比例增加；造成96.4%的大肠杆菌BL21细胞表面凹陷，胞质内容物流失，菌体体积缩小；导致枯草芽孢杆菌89.6%的细胞体积明显缩小；导致金黄色葡萄球菌基本没有细胞能形成完整的分裂隔膜；导致红酵母细胞能进行出芽生殖的比例从64.2%降低到19.3%，但对其细胞形态无明显改变.联苯代谢物2，3-二羟基联苯对红球菌R04及其它微生物细胞分裂和增殖的抑制作用比其前体-联苯强，建议在研究环境化合物与微生物互作时，应考虑环境化合物代谢的毒性效应.     

空间视角下湖北省环境绩效评估及影响因素分析

以湖北省为例，基于压力-状态-响应（PSR）模型构建环境绩效评估指标体系，运用空间自相关和标准差椭圆对湖北省各地区绩效指数空间特征及影响因素进行探讨，结果显示：湖北省各地区环境绩效指数（EPI）均高于60，但普遍处于中等水平，良好及优秀所占比例低.EPI较高的地区主要位于湖北省西部和中部，压力和状态指数从西至东递减，响应指数则呈现东部高于西部高于中部的态势.状态指标绩效指数在空间上显著正相关，即环境质量状况较好（或较差）的地区在空间上集聚.EPI及二级指标绩效指数均以西北-东南为布局方向，且EPI椭圆重心较于基准重心偏向于西南方向.各地区环境指数除受到资源禀赋的影响外，还与城镇化率和人口密度显著相关.     

世界旅游精品建设目标下的张家界旅游环境管理对策研究

建设世界旅游精品是张家界制定的旅游业发展的战略目标，一流的旅游环境条件是实现这一目标的必备条件。然而，张家界目前的旅游环境与世界旅游精品存在差距，环境管理中存在基础性工作、基础性研究比较薄弱、制度不够健全等方面的问题，影响了环境管理效率。在分析研究张家界环境管理中存在问题的基础上，针对性地提出保护、改善环境的对策，是实现世界旅游精品战略目标的基础工作。     

Alternative treatments for the municipal solid waste and domestic sewage in Campinas,Brazil

The treatments of municipal solid waste (MSW) and the domestic sewage (DS) are critical issues of the current political and environment discussions. These concerns are due to the lack of dumping areas, the continuous increase of the population, and public health issues. The adequate treatment and management of MSW and DS can produce many benefits such as financial funds, heat and energy production, reduction of emissions and recuperation of water for reuse. Currently in Campinas MSW and DS are deposited in landfills or discharged into rivers and other sites. In the present study two scenarios are evaluated for the treatment of MSW and DS in Campinas: recycling with biological treatment and recycling with thermal treatment. The most suitable treatments for Campinas, based on the data from the present analysis and taking into consideration the local conditions, maximization of energy potential and environmental benefits, are incineration for the MSW and biological treatment for DS, both with energy recuperation. The main gains of this option are substantial environmental benefits, generated energy which can reach 18% of the total electrical energy consumed in Campinas while about 53% recuperation of the total amount of water treated for Campinas in 2010.     

Assessing of Environmental Quality in Six Areas in India,Sri Lanka and Bangladesh

Environmental quality for environmental health has been examined visually by describing general conditions and drinking water supply, sanitation and solid waste treatment conditions and practices in six South-East Asian villages with a dense population. The environmental review was supplemented by discussions with local people and political and administrative decision makers. Some drinking water analyses were done in order to show the water quality to the local people. The quality of the general conditions and the conditions and practices of drinking water supply, excreta disposal and solid waste treatment practices have been graded with the grading system presented below. The grading could be done in 1 or 2 days in each area by two persons, of which one was an environmental scientist and the other a social scientist, who also knew the local culture and worked as a translator.
