应急避难场所在城市应急管理体系中占有重要地位，对已建成的应急避难场所选址进行评价，可为应急避难场所个体改进、布局优化和新建选址提供依据。本文在文献研究与天津市城市特点分析的基础上，从有效性、安全性、可达性3个维度构建包含8个评价因子的应急避难场所选址适宜性评价指标体系，应用层次分析法（AHP）确定指标权重。应用GIS空间分析技术建立应急避难场所空间点位分析模型和覆盖范围模型，对天津市27个应急避难场所进行适宜性评价，并对中心城区14个应急避难场所进行满足性评价。结果表明，天津市应急避难场所具有良好的基础，但总体适宜性水平有待进一步提高，尤其是安全性亟需加强；天津市中心城区人口密集，但应急避难场所数量少，服务区域有限，存在较大范围的覆盖盲区，其中和平区人均有效避难面积仅0.2m2，远小于人体最低占用面积0.6m2，达不到人均有效避难要求。 相似文献

本文针对2020年全国公众防震减灾科普满意度调查工作,设计了防震减灾科普公众接触率、受众收获评价、公众满意度和需求等指标,量化衡量防震减灾科普在公众中的触达现状、公众的收获评价、反馈评价和需求。调查结果显示,公众与防震减灾科普的接触较普遍,受众收获评价和满意度评价总体得分较高。防震减灾科普公众接触率在不同城乡、年龄、学历、职业等层面的群体差异较明显。科普活动的公众接触率相对较低,受众收获评价较高,公众对活动新颖性的满意度评价低于活动组织管理。科普作品的公众接触率最高,但受众收获评价较低,在促进公众技能提升方面具有明显短板,公众对作品形式新颖性的满意度评价低于内容通俗易懂性。科普场所的公众接触率最低,但受众收获评价最高,对公众知识、技能、意识的提升作用较好。公众对科普场所信息查找便利性的满意度较低,导致科普场所满意度评价低于科普活动和科普作品。分析表明,需重视公众需求和反馈,采取有针对性的措施进一步提升防震减灾科普效率。 相似文献

Climate change impacts the quantity and seasonality of rainfall, threatening Africans' ability to maintain satisfactory yields on rain-fed farms. On the semi-arid northwestern slopes of Mount Kenya, irrigation systems structured around Community Water Projects (CWPs) provide households with piped water, which helps mitigate drought impacts and enhances resilience to increasingly variable rainfall patterns. The vision of these irrigation systems is to equitably distribute water resources among CWP members both for household consumption and to maintain or improve agricultural yields. However, not all households receive equal quantities of water from their CWPs, and little is known about the impact of water provisioning on farmers' opinions or perceptions of CWP performance.In this study, we relate respondents' satisfaction with their CWPs to the quantity of water delivered. Not surprisingly, farmers who received low quantities of water from their CWPs expressed above-average rates of concern regarding drought. In contrast, satisfaction with one's CWP was unrelated to the absolute quantity of water received (log liters/minute), but it was strongly associated with relative measures of water delivery: respondents who received less water than other members of the same water project experienced high rates of dissatisfaction, as did respondents who received less water than in the past. These results suggest that Kenyan farmers may feel particularly dissatisfied—and, perhaps, particularly driven to demand improved water governance—when they perceive inadequate water delivery relative to some reference group.Because relative water quantity dictates satisfaction even after controlling for factors that can be resolved internally at the CWP level (by, for example, striving for uniformity of water flows across and within households), water project managers are limited to some degree in their ability to improve satisfaction through better governance. That said, governance actions that prevent declines in flows over time (e.g. maintaining infrastructure to reduce leaks) could ostensibly lead to meaningful improvements in member satisfaction. 相似文献

将数据包络分析法（DEA）应用于陕西气象资源效率评估,计算全省气象行业2007—2009年运行的综合效率值、技术效率值和规模效率值,得出综合效率和规模效率有所下降,而技术效率有所提升。其中,2009年技术效率均值为3年来最高,而2007年技术效率值为3年来最低。构造基于面板数据的气象计量经济模型对各影响效率的因素进行计量分析,气象服务用户群及公众满意度指数、农业产出GDP值占区域GDP总值的比重和资金投入强度与气象部门产出的综合效率值呈正向关系,学术论文发表数量与综合效率值呈反向关系。据此提出提升资源效率有效性的对策。 相似文献

江苏省公众气象服务满意度影响因素研究 总被引：1，自引：0，他引：1
通过江苏省气象局设计的《江苏省公众气象服务需求调查表》对江苏省13个市及各县区进行整群抽样调查,获取较大数量的公众气象服务满意度样本和数据,选取性别、年龄、属性、行业、本地居住时间、收入6个影响因素。运用单因素方差分析、多因素方差分析和多元线性回归模型,对江苏省公众气象服务满意度进行分析。结果显示在单因素方差分析中,除性别外,其余5个影响因素的差异均为显著。在多因素方差分析中双因素、3因素和4因素交互均不显著。通过多元线性回归进一步分析得出居住时间是影响满意度的最主要因素,而性别是影响最小的因素。 相似文献

This study analyzed information gathered from 200 date palm households in the mountainous Panjgur District of Balochistan in Pakistan with the aim of determining date farmers＇ access to and satisfaction with agricultural extension services. Information was collected through a structured questionnaire survey, group discussions and semi- structured personal interviews. The findings of the analysis revealed very poor access to extension services. The results of logistic regression analysis identified five variables out of six which significantly influence date farmers＇ access to extension services： household bead＇s age, household bead＇s literacy, number of date palm trees owned, mostly inherited date palm trees, and percentage of dead date palm trees. The overwhelming majority of farmers were dissatisfied with all three main types of extension services being provided by public extension officials. Explanations for this as well as for associations between access to extension services and the six independent variables are provided. Important policy conclusions are drawn based on the findings. 相似文献
