长湖水质现状调查及评价

通过对长湖13个点位的采样监测结果表明：（1）长湖的各项主要指标均已超标,特别是化学需氧量（CODcr）、高锰酸盐指数（OC）、总氮（TN）、总磷（TP）等超标严重;（2）从总体上看,长湖水体监测点位的水质是,上游污染情况较重,下游的出水口及大湖湖心水质稍好;（3）采用单项水质参数评价方法对长湖水质进行评价,水体已达到劣Ⅴ类.     

环境生物技术的研究现状及发展前景

环境生物技术（Environmental Biotechnology）简称EBT，是近20年来才定义的新型边缘学科。环境生物技术主要由生物技术、工程学、环境学和生态学组成。一般认为生物工程即生物技术，是指综合应用生物学、化学和工程学等手段，直接或间接地利用生物体本身，生物体某些组分或某些特殊机能，生产有用物质的一门综合性科学体系。它的产生和发展涉及多种学科，既反映了基础科学研究的最新成果，也体现了工程科学开拓出来的新技术和新工艺。     

Children’s fear in traffic and its association with pedestrian decisions

Introduction: Research on risk for child pedestrian injury risk focuses primarily on cognitive risk factors, but emotional states such as fear may also be relevant to injury risk. The current study examined children's perception of fear in various traffic situations and the relationship between fear perception and pedestrian decisions. Method: 150 children aged 6–12-years old made pedestrian decisions using a table-top road model. Their perceived fear in the pedestrian context was assessed. Results: Children reported greater emotional fear when they faced quicker traffic, shorter distances from approaching traffic, and red rather than green traffic signals. Children who were more fearful made safer pedestrian decisions in more challenging traffic situations. However, when the least risky traffic situation was presented, fear was associated with more errors in children’s pedestrian decisions: fearful children failed to cross the street when they could have done so safely. Perception of fear did not vary by child age, although safe pedestrian decisions were more common among the older children. Conclusions: Children’s emotional fear may predict risk-taking in traffic. When traffic situations are challenging to cross within, fear may appropriately create safer decisions. However, when the traffic situation is less risky, feelings of fear could lead to excessive caution and inefficiency. Practical applications: Child pedestrian safety interventions may benefit by incorporating activities that introduce realistic fear of traffic risks into broader safety lessons.

桐麦间作人工群落空间分布格局的灰色局势决策

本文采用多目标灰色局势决策的方法，以桐麦间作人工群落为例，以１０年为泡桐生长的一个轮伐期，以６种不同的空间配置方式作为对策，以林业经济收益、农业经济收益和系统总体效益为目标，进行多目标决策，定量研究其空间分布格局。研究结果表明，以农为主间作型泡桐的最佳株行距为５×４０ｍ，以桐为主间作型的为５×５ｍ，农桐并重间作型的为５×２０ｍ。
