我院环境科研组与重庆环监所、西南农学院土化系合作,对重庆地区土壤背景值进行调查研究,获得可喜成果。 今年5月25日至27日,重庆市环境保护局主持召开省内外二十几个单位的有关专家、科技工作者和科研管理人员40多人参加的鉴定会,对这项科研成果作了肯定。与会者一致认为:这项成果在采样设计,分析方法,数据处理和结果表示等方面,较之以前有所进步,在某些方面具有国内先进水平,对我国土壤背景值研究工作作出了贡献。根据重庆地区的自然地理特征和土壤类型,创造性地采用点面结合,分层随机取样的设计方案,并在数理统计基础上初步验证了最佳样本容量。这种取
The environmental research team of our institute cooperated with Chongqing Environment Monitoring Office and Southwest Agricultural College to investigate and study the soil background value in Chongqing and obtained gratifying results. From May 25 to 27 this year, Chongqing Environmental Protection Bureau presided over an appraisal meeting attended by more than 40 experts, scientists and technologists and scientific research managers from over 20 units inside and outside the province, and affirmed the achievement of this scientific research . Participants agreed that this result has made some progress in sampling design, analysis method, data processing and result presentation, compared with the previous ones, and in some aspects, it has domestic advanced level and contributed to the research on soil background value in our country. Based on the natural geographical features and soil types in Chongqing, the design scheme of point-by-plane combination and stratified random sampling was creatively adopted. The optimal sample size was preliminarily verified on the basis of mathematical statistics. This kind of take
