The place of nature in conservation conflicts

Conservation conflicts are gaining importance in contemporary conservation scholarship such that conservation may have entered a conflict hype. We attempted to uncover and deconstruct the normative assumptions behind such studies by raising several questions: what are conservation conflicts, what justifies the attention they receive, do conservation-conflict studies limit wildlife conservation, is scientific knowledge stacked against wildlife in conservation conflicts, do conservation-conflict studies adopt a specific view of democracy, can laws be used to force conservation outcomes, why is flexibility needed in managing conservation conflicts, can conservation conflicts be managed by promoting tolerance, and who needs to compromise in conservation conflicts? We suggest that many of the intellectual premises in the field may defang conservation and prevent it from truly addressing the current conservation crisis as it accelerates. By framing conservation conflicts as conflicts between people about wildlife or nature, the field insidiously transfers guilt, whereby human activities are no longer blamed for causing species decline and extinctions but conservation is instead blamed for causing social conflicts. When the focus is on mitigating social conflicts without limiting in any powerful way human activities damaging to nature, conservation-conflict studies risk keeping conservation within the limits of human activities, instead of keeping human activities within the limits of nature. For conservation to successfully stop the biodiversity crisis, we suggest the alternative goal of recognizing nature's right to existence to maintenance of ecological functions and evolutionary processes. Nature being a rights bearer or legal person would imply its needs must be explicitly taken into account in conflict adjudication. If, even in conservation, nature's interests come second to human interests, it may be no surprise that conservation cannot succeed.     

英国国防工业安全生产法制体系研究及对我国的启示

为建立健全我国国防工业安全生产法制体系，从构建历程、宏观设计和微观建设要点等方面对英国国防工业安全生产法制体系展开系统研究，并分析当前我国国防工业安全生产法制体系存在的主要问题以及英国国防工业安全生产法制体系建设对我国的启示。结果表明:在宏观设计方面，英国构建以国防安全局为监管主体的高度扁平化监管体系；在微观建设方面，其更加注重国防工业安全生产法律体系的层次性、内容完备性，法律的实操性、更新机制，以及监管职责界定的建设。借鉴英国经验，指出将国防工业安全生产法制体系建设提升至国家战略高度，实现国防工业安全生产专门立法、强化法律可操作性、完善法律制修订机制和科学界定监管职责是我国今后努力的重要方向。     

Locating Co-presence in Media Messages about Global Warming

This paper responds to recent calls for alternative approaches to the analysis of environmental communication that uncover overlooked voices in the discussion of environmental issues. Borrowing core principles from critical rhetoric, it suggests a way to categorize media messages according to how human–nature relationships are constructed in media discourse. The paper illustrates how, in presenting contrasting and often oppositional constructions of human–nature relationships, the media messages examined articulate three recurrent (but not equal) discourses on global warming. These discourses include (1) nature-as-out-of-reach discourse, (2) nature-as-antagonist discourse, and (3) nature-as-co-present discourse. By juxtaposing these discourses, the paper shows how environmental communication scholars can engage in critical realism and political advocacy to illuminate latent public discourse that holds the potential to champion marginalized voices of nature and accentuate the interconnectedness of humans and the environment.     

Biomimicry: How the environment serves as a guide for technological advancements

Multiple ecological tactics, like the ones described here, can be imitated to strongly affect these two components in the construction sector. This article provides an in-depth examination of the literature on biomimicry-based strategies intended to enhance building designs. This analysis is motivated by the rising need for energy legislation to achieve future local goals and provide a framework for use in Panama. These biomimicry-based methods have undergone more review and evaluation, and the incorporation of organism-based design for three of Panama's climate types has been proposed. Therefore, a SWOT analysis assisted in realizing the full potential that biomimicry-based techniques might have in raising the likelihood of satisfying local and international regulatory standards. In order to design constructions using biomimicry, multidisciplinary collaboration is required. This gives a competitive edge for better-trained human resources and expands horizons in the conventional construction industry. Finally, the analysis provided here might act as the preliminary step for the additional technical assessment using numerical and experimental procedures.     

国家重点生态功能区县域环境监测质量评价方法及应用示范

以国家重点生态功能区县域环境监测质量评价为目标,综合应用德尔菲法、层次分析法和模糊综合评价法,构建了国家重点生态功能区县域环境监测质量评价方法,并确定了评价因子、权重系数、计算方法。该方法评价指标共分为三层:第一层为目标层,即国家重点生态功能区县域环境监测质量;第二层为准则层,包括人员及资质、现场监测、实验室管理、报告编制及数据上报;第三层为方案层,包括人员操作、持证上岗、资质认定、人员培训、水质布点采样流转情况、空气自动站运维情况、现场质控实施情况、实验室环境条件、样品试剂的保存与管理、仪器检定与校准、实验室质量控制实施情况、数据填报软件运行情况、监测报告规范性等13个评价要素。经矩阵一致性检验确定了各评价要素的权重,将该权重与各要素得分运算后得到县域环境监测质量评价结果。在此基础上,选取广东、山西、陕西、四川和青海等5个省份的15个国家重点生态功能区县域作为典型区开展了实地调研,并应用评价体系对其进行了监测质量等级评价。结果表明,15个典型县域中,环境监测质量等级为优的县域占13.3%,一般、较差的县域分别占66.7%、20%。县域环境监测承担单位在资质、报告编制及数据上报方面表现较好,在现场监测、人员操作方面问题突出,在实验室管理方面有待提升。

基于Kriging插值的路旁土壤重金属含量空间分布 ——以310国道郑州-开封段为例

分别在G310国道郑州-开封段的杏花营路段两侧150m×150m范围内布设7条垂直于公路的采样子断面,从路肩向两侧每隔10m采集1个表土混合样,共采集226个样品（包括2个对照样品）.用ICP-MS测定了土壤重金属（Pb、Cu、Zn、Cd、Cr和Ni）含量,并用Universal Kriging插值法分析路旁土壤重金属空间分布特征.结果表明,路旁土壤重金属呈与道路平行的带状分布,表明6种重金属含量均受公路交通影响,属于公路源重金属.土壤Cr和Cu含量在路基处含量最高,向两侧逐渐下降,呈指数分布;土壤Pb、Zn、Cd和Ni含量在距路基30～50m处出现峰值,呈偏态分布.路旁土壤Pb、Cu、Zn、Cd、Cr和Ni均为交通源重金属.     

多源数据支持下城市火灾风险评估及规划响应

为探析城市火灾风险的空间格局特征,提出科学的火灾防控体系,以合肥市为研究对象,基于火灾风险兴趣点(POI)数据、NPP/VIIRS夜间灯光影像数据、消防站与道路信息等多源数据,运用SAVEE模型和迭代方程评估城市火灾风险,并引入区位-配置(L-A)模型,从不同目标情境优化消防站点布局。研究表明:火灾高风险区主要集中于合肥市二环以内的建成区,尤其是老城区、合肥西站片区、政务区、科学城和东部新中心等区域;现有48座消防站对研究区内的POI覆盖效果较好,覆盖率为86.76%,而对NPP/VIIRS覆盖效果一般,覆盖率仅为55.94%,覆盖率在合肥市东北部、西北部和南部部分地区仍有不足;基于最大化覆盖模型,规划新增44座消防站,明显提升5 min响应时间的覆盖率,可进一步夯实城市消防安全。     

中国表层土壤有机质空间分布模拟分析方法研究

气候变化背景下,对土壤有机碳的研究是目前大尺度上土壤性质研究的热点。基于第二次全国土壤普查5 374个典型土壤剖面数据,分析表层土壤有机质(20 cm)与环境因素的相关关系,利用多元回归模型和HASM模型结合的方法模拟中国国家尺度上表层土壤有机质含量的空间分布格局,探讨该方法的模拟误差,为国家尺度上有机碳的估算提供方法参考。研究结果表明,对350个检验点模拟结果的平均绝对误差和平均相对误差为15.61 g.kg-1和56.59%,与普通克里格法相比分别降低了1.61 g.kg-1和20.84%;对样点分布较少以及无样点的西北地区和台湾省的模拟结果也更符合实际情况。建模样点减少一半的情况下,模拟结果的平均绝对误差和平均相对误差仅分别增加了0.14 g.kg-1和1.07%。因此,论文方法可作为模拟国家尺度上有机质空间分布相对有效的方法,同时如何使模型解释更多的土壤有机质空间变异将是进一步提高模拟精度的关键。
