突发性环境污染事故应急监测的措施分析

突发性环境污染事故会对环境造成较大的伤害,如果不能及时采取措施,就会使污染进一步扩大,不仅带来经济的损失,而且会破坏到生态的平衡。因此,要建立起突发环境污染事故的应急监测,这样才能尽可能的减少突发性环境污染事件的影响。基于此,本文从突发性环境污染事故的特征入手,首先分析其应急监测的意义,然后探究具体的措施,希望可以借此给突发性环境污染应急监测的相关研究提供一定的参考意见。     

Images of war: using satellite images for human rights monitoring in Turkish Kurdistan

In areas of war and armed conflict it is difficult to get trustworthy and coherent information. Civil society and human rights groups often face problems of dealing with fragmented witness reports, disinformation of war propaganda, and difficult direct access to these areas. Turkish Kurdistan was used as a case study of armed conflict to evaluate the potential use of satellite images for verification of witness reports collected by human rights groups. The Turkish army was reported to be burning forests, fields and villages as a strategy in the conflict against guerrilla uprising. This paper concludes that satellite images are useful to validate witness reports of forest fires. Even though the use of this technology for human rights groups will depend on some feasibility factors such as prices, access and expertise, the images proved to be key for analysis of spatial aspects of conflict and valuable for reconstructing a more trustworthy picture.     

降雨主导型库岸滑坡变形时空分布特征

根据某大型水库近坝库岸滑坡8年的监测资料,对该滑坡变形的时空分布特征进行了分析。该滑坡变形的空间分布特征主要表现为3个方面的差异,即区域差异、高程差异和深度差异。而滑坡变形的时间分布特征主要体现在库水作用和降雨两个方面:在重点监测的Ⅱ区,库水作用只影响到其前端部分,对中、后部影响很小;该区的整体变形与降雨关系密切,响应明显。这些特征表明该滑坡为降雨主导型库岸滑坡,并有向稳定方向发展的趋势;但Ⅱ区特有的"后坐式"变形特征又存在一定的安全隐患,因此,该滑坡的监测还应长期进行。     

获取日均值的大气监测时段选择

利用数理统计方法，以污染物瞬时监测数据为基础数据，选用控制在一定置信度下最大允许误差的统计公式确定出样本容量，并采用模糊集合运算—优化组合选择法，确定出获取日均值的最佳监测时段．     

NABat: A top-down,bottom-up solution to collaborative continental-scale monitoring

Collaborative monitoring over broad scales and levels of ecological organization can inform conservation efforts necessary to address the contemporary biodiversity crisis. An important challenge to collaborative monitoring is motivating local engagement with enough buy-in from stakeholders while providing adequate top-down direction for scientific rigor, quality control, and coordination. Collaborative monitoring must reconcile this inherent tension between top-down control and bottom-up engagement. Highly mobile and cryptic taxa, such as bats, present a particularly acute challenge. Given their scale of movement, complex life histories, and rapidly expanding threats, understanding population trends of bats requires coordinated broad-scale collaborative monitoring. The North American Bat Monitoring Program (NABat) reconciles top-down, bottom-up tension with a hierarchical master sample survey design, integrated data analysis, dynamic data curation, regional monitoring hubs, and knowledge delivery through web-based infrastructure. NABat supports collaborative monitoring across spatial and organizational scales and the full annual lifecycle of bats.     

中国工业废水治理效率评价

基于投入产出的思想,应用DEA模型对2008年中国工业废水治理效率进行静态评价,得出各地区当前工业废水治理效率.用Malmquist指数对中国2003-2008年工业废水治理效率进行动态评价,分别得出近几年中国工业废水治理的名义全要素生产率和实际全要素生产率.结果表明,中国工业废水平均治理效率仅为0.630,2008年达到DEA有效的地区仅占16.7％,几乎所有地区都处在规模收益递减;2003-2008年间的中国工业废水治理名义T下P为0.922,实际TFP为0.943,即分别在此期间平均每年下降7.8％和5.7％,造成逐年下降的主要原因是技术的落后.

LANDSAT MID-INFRARED DATA AND GIS IN REGIONAL SURFACE SOIL-MOISTURE ASSESSMENT1

ABSTRACT: Landsat satellite Thematic Mapper (TM) data were used to assess regional soil moisture conditions. The mid-infrared (MIR) data of TM band 7 were overlain onto four principal land-use categories (Agricultural/Irrigated, Urban/Clearings, Forest/ Wetlands, Water) using a geographic information system (GIS). M data were used to assess four qualitative surface soil-moisture conditions (water/very wet, wet, moist, and dry) within each land-use category of a 208,354 ha southwestern Florida study area. The MIR response was inversely related to the qualitative surface soil-moisture content. Integration of Landsat TM MIR data with land use through GIS appears to be a useful technique for high-resolution regional soil moisture assessment, and further research to reline this technique is recommended.
