Gaps in provincial decision-maker’s perception and knowledge of climate change adaptation in China

The perspectives and knowledge of decision makers, especially those at the provincial level, have great impact on the progress of climate change adaptation in China. Therefore, identifying knowledge gaps and enhancing climate adaptation awareness of decision makers at that level is very important. Based on this aim, we conducted a survey of climate change adaptation awareness among 85 administrative and management personnel from governmental departments responsible for climate change adaptation planning in five provinces. Study findings revealed that over half of respondents have knowledge of climate change adaptation measures, but the extent of understanding varied across different adaptation aspects and regions. Among the different aspects, understanding of measures related to human health protection was the lowest. A large majority of respondents indicated an eagerness to obtain knowledge and information about climate change adaptation, but the main barrier is a lack of training and learning material. When making adaptation plans or policies, the greatest obstacle expressed was a funding shortage. Information generated from this study can provide direction and guidance for training and educating provincial decision makers in order to improve the levels of adaptation planning and policy making.     

辐射化学剂量计在强脉冲混合辐射场测定中的应用

本文讨论了将硫酸亚铁剂量计和铜－铁剂量计用于强脉冲混合辐射场测定的实验设计,利用直径２２０毫米的聚乙烯球,将硫酸亚铁剂量计的快中子响应降低到２０％以下,由它和完全暴露在中子、γ混合场中的硫酸亚铁剂量计响应之差,测量中子吸收剂量。这种方法两次实际用于强脉冲混合辐射场中子、γ吸收剂量测量,得到的结果和热释光剂量计、固体径迹探测器的测量结果进行了比较,在±２５％的误差范围内一致     

Method for determining minimum pool requirements to maintain and enhance salmonid fisheries in small Wyoming reservoirs

Methods for determination of minimum pool levels in reservoirs that consider sport fishery values are being sought by managers. We developed a technique for assessing the effects of incremental changes in minimum pool levels on potential salmonid abundance in small (<100 surface hectares at full pool) reservoirs in Wyoming managed for irrigation and municipal water supplies. The method has two components. One component is used to determine the minimum pool level needed to eliminate the risk of overwinter loss of salmonids due to low dissolved oxygen concentrations. The other component predicts the potential biomass of salmonids in reservoirs as a function of water depth and total dissolved solids concentration of the reservoir water. Application of the method is demonstrated for two reservoirs in Wyoming. The unit is jointly supported by the University of Wyoming, the Wyoming Game and Fish Department, and the US Fish and Wildlife Service.

巢湖14~#井水位微动态异常研究

应用微动态异常频次、Ｍ２波振幅比等方法,对巢湖１４＃井水位１９８７～１９９７年进行了全过程的分析研究。研究结果表明：在华东几次中强震前,该井水位的微动态异常频次在地震前３～４个月有明显增高的异常显示,而水位Ｍ２波振幅比在地震前也存在３～４个月的下降异常。由此可以认为该井有可能成为华东及东部沿海５级以上地震的灵敏井点之一,而且在地震的短期预测方面可能会提供有益的异常信息。

哈密地区饮用水总α,总β放射性比活度评价

报告了哈密地区居民饮用水总α、总β放射性比活度平均值分别为11.6(1.4～79.4)×10~(-2)Bq·L~(-1)(另有一突出值287.0×10~(-2)Bq·L~(-1)未计入平均值);0.40(0.05～1.76)Bq·L~(-1).估算结果表明,本地区95％以上居民的饮用水源是安全的。     

珠江三角洲腹地洪水位异常变化及成因分析

珠江三角洲是我国东南沿海的经济发达地区.三角洲地区的防洪安全保障对区域的社会、经济发展具有举足轻重的作用.由于三角洲地区复杂的网河及口门构成,以及径流和潮汐共同影响的水动力条件,使三角洲的洪水水势表现出随时间和空间复杂变化的动态特征.20世纪80年代以来,三角洲地区受水土资源无序开发的人类活动的影响,90年代的洪水表现出了网河腹地河段洪水位异常壅高的现象,使区域的防洪安全受到严重威胁.结合"94.6","98.6"洪水期间三角洲腹地洪水水位异常壅高现象,综合分析了区域洪水位异常壅高的外部及内在成因,为科学制订三角洲地区防洪对策提供技术依据.
