北京市农村地区清洁取暖运行效果监测评价

为了全面掌握北京市农村地区清洁取暖设备的实际运行效果,采用先进的物联网、设备监控及云应用技术,建立了北京市级清洁取暖运行效果监测平台,实时监测清洁取暖系统的运行状态和运行性能参数。通过对2017-2018年供暖季清洁取暖运行效果的监测数据进行分析,认为北京市农村地区清洁供暖系统总体运行安全可靠,热泵类清洁取暖技术的能耗和运行费用最低。

北京农村教师专业发展模式及存在问题的调查

为了全面了解北京市农村地区教师专业发展的现状,在对北京市十个农村地区进行了大样本问卷调查和深入访谈后,经过定量与定性数据分析得出以下结论:北京市农村地区目前主要存在教师个体专业发展模式、大学与中小学合作的教师专业发展模式、中小学校本研修模式、与城区合作的教师专业发展模式等四种教师专业发展模式。北京市农村地区教师专业发展存在的问题有:教师队伍建设困难,教师专业发展缺乏专业引领和工学矛盾突出等。

北京市农村污水处理方法及效果

为研究农村污水特点,针对性选择处理工艺,对北京市通州、房山、昌平、怀柔、密云等5个区县的4种类型村庄的污水结构、用水量、污水排放量、污染物浓度进行调查研究,同时对6种污水处理工艺进行污染物去除率、建设运行费用、占地面积进行调查研究。结果显示:京郊农村污水主要由厨房污水、生活洗涤污水、冲厕污水、养殖污水组成;污水排放规律为夏季大、冬季小,污水污染物种类多,城乡结合部村水质最差,山区村水质最好。综合分析表明,MBR、MBR+土地渗滤、A/O+土地处理系统工艺适宜在平原地区经济条件较好的村庄及城乡结合部村庄使用;人工湿地工艺适宜在面积大、经济条件较差、对出水水质要求不高的平原区村庄使用;山区村庄可考虑采用厌氧生物滤池处理技术;民俗旅游村等经济条件较好、出水水质要求较高的村镇地区可考虑采用MBR工艺及一些高效组合工艺。

Research on the Achievement Motivation of the University Student Village Officials in the Suburbs of Beijing

[Objective] The aim was to explore the achievement motivation of the university student village officials in the suburbs of Beijing.[Method] The research made an investigation on 429 university student village officials in the suburbs of Beijing by the Achievements Motive Scale(AMS).[Result] The achievement motivation of these student village officials was not on a high level,but they tended to pursue the success motivation rather than the motivation to avoid failures obviously.There was a significant difference in the achievement motivation between different genders,majors and jobs.The males' motivation for success was higher than the females'.The motivation of avoiding failures among officials in Humanities was higher than in Science and in Fine Art.And the university student village officials in professional and technical posts or in business posts rated the motivation to avoid failures more important than in basic management posts.But achievement motivations in different urban-rural areas,educational levels,political backgrounds,whether student leaders or not,and durations were no definite differences.Besides,it had a significant effect on these student village officials' achievement motivation whether advices and suggestions were accepted;if yes,the motivation was higher.[Conclusion] This study had provided stability and development for building rural talent groups.

京郊生活污水处理设施运行现状调研与分析

北京农村地区水污染治理力度不断增大,但因缺乏借鉴模式和管理经验,加之部分规划设计不合理,在操作、运行等方面存在诸多问题。开展京郊污水处理设施运行现状调研及相关管理机制研究,已成为北京市新农村治污规划工作的迫切需求。通过实地调研,摸清了镇级和村级污水处理设施数量、分布及运行现状,明确了存在的主要问题,对其产生原因进行了深入分析,在此基础上,探讨并提出了三种污水处理设施管理模式,通过经济比选和实践效果分析,最终确定村镇与专业公司相结合的管理模式和机制是最适合京郊发展实际的。
