Empirical Trials of Plant Field Guides

We designed 3 image‐based field guides to tropical forest plant species in Ghana, Grenada, and Cameroon and tested them with 1095 local residents and 20 botanists in the United Kingdom. We compared users’ identification accuracy with different image formats, including drawings, specimen photos, living plant photos, and paintings. We compared users’ accuracy with the guides to their accuracy with only their prior knowledge of the flora. We asked respondents to score each format for usability, beauty, and how much they would pay for it. Prior knowledge of plant names was generally low (<22%). With a few exceptions, identification accuracy did not differ significantly among image formats. In Cameroon, users identifying sterile Cola species achieved 46–56% accuracy across formats; identification was most accurate with living plant photos. Botanists in the United Kingdom accurately identified 82–93% of the same Cameroonian species; identification was most accurate with specimens. In Grenada, users accurately identified 74–82% of plants; drawings yielded significantly less accurate identifications than paintings and photos of living plants. In Ghana, users accurately identified 85% of plants. Digital color photos of living plants ranked high for beauty, usability, and what users would pay. Black and white drawings ranked low. Our results show the potential and limitations of the use of field guides and nonspecialists to identify plants, for example, in conservation applications. We recommend authors of plant field guides use the cheapest or easiest illustration format because image type had limited bearing on accuracy; match the type of illustration to the most likely use of the guide for slight improvements in accuracy; avoid black and white formats unless the audience is experienced at interpreting illustrations or keeping costs low is imperative; discourage false‐positive identifications, which were common; and encourage users to ask an expert or use a herbarium for groups that are difficult to identify.

京津冀区域燃煤发电行业大气污染物排放时空变化特征研究

为了科学评估京津冀区域燃煤发电行业特别排放限值和超低排放相关要求实施后的大气污染物减排效果,以行业调查数据为基础,建立了2013年和2015年京津冀区域燃煤发电行业大气污染物排放清单,分析了装机容量与SO_2、NO_x和烟尘排放量的时空耦合关系,讨论了国家相关政策和标准的实施效果。结果显示:区域内2015年燃煤机组装机容量与2013年相比略有下降,SO_2、NO_x和烟尘排放量分别下降75.95%、83.09%和71.20%,减排效果明显。2015年100 MW以下等级机组3种污染物排放总量位居各机组首位,建议通过多种合理方式压减小型燃煤发电机组数量和排放浓度。
