公众气象服务满意度问卷调查分析 总被引：1，自引：0，他引：1
针对天气预报服务中的不足之处,通过对四川省气象服务满意度的调查评估,为今后提高气象信息在社会、经济等领域的应用提供参考。根据CSIWS测量模型,从受众对气象服务的评价、对气象信息的了解、对气象信息的理解、对气象服务的要求4方面进行调查。有效问卷结果分析表明：（1）公众对四川省“气象部门公众形象”的评价最高,满意度指数达到90．60％;（2）公众对“天气预报准确率”期望值最高,为4．13分;而满意度为3．30分,两者差距0．83分,说明表现尚达不到社会公众的期望值,今后在提高天气预报准确率方面仍需下大力气;（3）评价满意度指数平均值为85．60％,社会公众对气象部门公众形象评价比较高,其余指标的满意度指数都有待进一步提高,但提高的迫切程度各有差异。 相似文献

Urban sprawl and related problems: Bibliometric analysis and refined analysis from 1991 to 2011 总被引：1，自引：0，他引：1
To shed light on the general patterns and trends in urban sprawl research,and to provide reference for future study,bibliometric analysis and refined analysis are conducted for publications in this area from 1991 to 2011.The general publication output,the global geographical distribution of the authors,the funding and institutions involved,the research areas,and the source titles are analyzed and discussed.Scholars in the United States and China have produced most of the documents in urban sprawl and these two countries are also the largest contributors in terms of funding and institutions.′Environmental SciencesEcology′,′Urban Studies′,and′Geography′are the most common research areas,and the journal titled Urban Studies has contributed the most articles.Furthermore,the refined analyses on the 500 top-cited and most relevant publications have revealed that research on urban sprawl is closely associated with the categories of′Urban form and development′,′Land use/land development′and′environment/ecology/biology′.Conclusions are made with respect to the basic paradigm of research on urban sprawl.The multi-disciplinary research into urban sprawl are expected to be more diversified and integrated. 相似文献

Heat balance of urban ecosystem is a key point for the study of urban climate and micro-climate pattern and its change mechanism. Urban heat island effect is becoming increasingly serious,which is mainly caused by the change of the earth's surface cover and the anthropogenic heat release. In this study,the simulation experiment for the anthropogenic heat release was designed according to the heat balance principle. A set of buildings of miniature city were used to constitute the residential area,U grooves were applied to simulate the single building,and the fluorescent lamps in the U groove were regarded as the heat sources of the anthropogenic heat release. The simulation experiment was launched with long-short wave sun photometer,sonic anemothermometer and heat flow gauge in the experiment site. Then the net solar radiation,sensible heat flux and heat flux into the ground were determined. The quantities of the anthropogenic heat release were calculated based on the heat balance principle,and were compared with the theoretical power consumption of the fluorescent lamps. The root mean square error( RMSE) of the simulation for the anthropogenic heat release reaches0. 078 W·m- 2,a comparatively high precision,which showes that the anthropogenic heat release can be accurately determined through the simulation experiments. This study provided a scientific method for the purpose of monitoring the anthropogenic heat release. 相似文献

The heavy floods in the Taihu Basin Showed increasing trend in recent years.In this work,a typical area in the northern Taihu Basin was selected for flood rish analysis and potential flood losses assessment.human activities have strong impact on the study area‘s flood situation(as affected by the polders built,deforestation,population increase,urbanization,etc.) and have made water level higher,flood duration shorter,and flood peaks sharper.Five years of different flood return periods[(1970),5(1962),10(1987),20(1954),50(1991)] were used to calculate the potential flood risk area and its losses.The potential flood risk map,economic losses,and flood-impacted population were also calculated.The study‘s main conclusions are:1) Human activities have strongly changed the natural flood situation in the study area,increasing runoff and flooding;2) The flood risk area is closely related with the precipitation center;3) Polder construction has successfully protected land from flood.Shortened the flood duration,and elevated water leel in rivers outside the polders;4) Economic and social development have caused flood losses to increase in recent years. 相似文献
