我国应急预案体系现状及展望——以上海为例

应急预案在自然灾害等突发事件发生时可以起到迅速反应的作用,因此成为突发事件应急管理中重要的一环。我国的应急预案体系已经基本建成,但还存在着预案格式雷同、脱离部门实际、分级体系科学性和可操作性不强、不同预案间接洽性不够、预案建设数量质量不够、缺乏后续管理等种种问题。分析了国内应急预案体系的现状,并探讨了对应急预案体系的改进方法。

Past, Status Quo and Future of China’s Territorial Planning

Since 1949, China has witnessed four development stages of territorial planning. （1） In the 1950s the territorial planning got its start. （2） From the 1960s to 1970s territorial planning declined. （3） From, the 1980s to 1990s the first major tide of territorial planning began. （4） From the end of the 1990s to recent times the new round of territorial planning is under deliberation. Since 1998, the Ministry of Land and Resources has carried out some related work, especially in organizing pilot projects, and early research on the new round of national territorial planning. According to the need for economic and social development and the current conditions in China, it is the appropriate for China to carry out the new round of territorial planning. However, the government should correctly consider the correlations between territorial planning and other plan- nings, and take appropriate development action, e.g. stressing main points for the basis of overall planning, building a territorial planning system that coordinate with national conditions, strengthening research on various supportive measures of territorial planning, summarizing and upgrading experiences obtained in pilot projects, strengthening international exchange and training talented personnel.

乌鲁木齐市声环境状况调查及对策分析

噪声污染作为城市的四大公害之一,随着城市规模、交通运输和娱乐业的发展,乌市的城市噪声污染在迅速上升。1996－2000年,乌鲁木齐市交通噪声的等效声级超过70dB(A) 的路段占46．47％;城市区域噪声也委严重,乌鲁木齐市昼间暴露在56dB(A)等效声级以上的区域覆盖人口约41．04万人,占网格人口的62．92％;城市工业噪声和建筑施工噪声污染也呈上升趋势,由此而引发的环境纠纷不断。因此,噪声污染综合整治已刻不容缓。以乌鲁木齐市的声环境质量现状,分析其主要影响因素并寻求合理的治理措施和方案。     

Testosterone and melanin-based black plumage coloration: a comparative study

Despite the functional significance of melanin-based plumage coloration in social and sexual signaling, the mechanisms controlling its information content are poorly understood. The T-regulation hypothesis proposes that melanin ornaments signal competitive abilities via the effects of testosterone (T) mediating both melanization and sexual/aggressive behaviors. Using the phylogenetic comparative approach, we tested whether frontal black melanization is associated with elevated T around the time of breeding plumage development across all bird species with available T-data. We found a context-dependent relationship between melanization and T, varying with the type of ornamentation (patchy or full-black) and with the presumed taxonomic distribution of the hormonal control of plumage dichromatism. Within two taxa in which male plumage development is assumed androgen-dependent (Charadriiformes, Corvida), evolutionary increases in male melanization, and melanin dichromatism correlated with increases in T in most analyses but not within the basal lineage (ratites, Galloanseriformes) with androgen-independent male plumage. Among Passeroidea with presumably genetically or luteinizing-hormone-based male plumage, melanization and its dichromatism correlated with T only in species with <100% frontal melanization. These results were robust as we controlled for several confounding variables such as mating and parental behaviors. This study is the first to test and support the T-regulation hypothesis interspecifically, suggesting that among-species differences in melanization may have evolved in response to differences in circulating T in certain avian taxa. Our results imply that the extent of black ornamentation may serve as an honest indicator of male competitiveness in those species that evolved an appropriate hormonal basis (T dependence) for color production.
