Use of demand for and spatial flow of ecosystem services to identify priority areas

Policies and research increasingly focus on the protection of ecosystem services (ESs) through priority‐area conservation. Priority areas for ESs should be identified based on ES capacity and ES demand and account for the connections between areas of ES capacity and demand (flow) resulting in areas of unique demand–supply connections (flow zones). We tested ways to account for ES demand and flow zones to identify priority areas in the European Union. We mapped the capacity and demand of a global (carbon sequestration), a regional (flood regulation), and 3 local ESs (air quality, pollination, and urban leisure). We used Zonation software to identify priority areas for ESs based on 6 tests: with and without accounting for ES demand and 4 tests that accounted for the effect of ES flow zone. There was only 37.1% overlap between the 25% of priority areas that encompassed the most ESs with and without accounting for ES demand. The level of ESs maintained in the priority areas increased from 23.2% to 57.9% after accounting for ES demand, especially for ESs with a small flow zone. Accounting for flow zone had a small effect on the location of priority areas and level of ESs maintained but resulted in fewer flow zones without ES maintained relative to ignoring flow zones. Accounting for demand and flow zones enhanced representation and distribution of ESs with local to regional flow zones without large trade‐offs relative to the global ES. We found that ignoring ES demand led to the identification of priority areas in remote regions where benefits from ES capacity to society were small. Incorporating ESs in conservation planning should therefore always account for ES demand to identify an effective priority network for ESs.

干污泥高维填埋的堆体边坡稳定性模拟与分析

污泥高维填埋可以解决污泥产量剧增与填埋用地紧张的矛盾,但污泥混合高维填埋的边坡稳定性需进一步考证.本文以抗压强度和抗剪强度均较强的含水率60%左右的干污泥为研究对象,采用GEO-SLOPE软件对污泥高维填埋堆体稳定性进行模拟分析,发现填埋放坡坡度越缓,堆体稳定性越强,所允许的最大填埋高度相应越高,库容增加量越大;填埋高度越高,堆体稳定性越差;以上海老港填埋场为例,填埋单元的最佳放坡坡度为1：3.5,相应的最大允许填埋高度为28m,库容增加量为447.2万m³.     

Predication of Fhhh potential in PTA wastewater treatment

Ebis is the intelligent environmental biotechnological informatics software developed for judging the effectiveness of the microorganism strain in the industrial wastewater treatment system(IWTS) at the optimal status. The parameter, as the objective function for the judgment, is the minimum reactor volume ( Vmin ) calculated by Ebis for microorganism required in wastewater treatment. The rationality and the universality of Ebis were demonstrated in the domestic sewage treatment system(DSTS) with the data published in US Aand China at first, then Fhhh strain‘s potential for treating the purified terephthalic acid(PTA) was proved. It suggests that Ebis would be useful and universal for predicating the technique effectiveness in both DSTS and IWTS.     

基于SPSS的盐城自然保护区近海海域水质污染状况的分析

根据盐城自然保护区近海海域的监测数据,选取五大类代表指标,9个监测断面,运用SPSS统计软件对污染因子及主成分进行分析,研究主要污染因子的组合,并对相应污染源进行分析;通过聚类分析对近海海域的监测点及各监测点的污染数据进行分类,优化近海海域监测站点的分布,分析结果表明盐城自然保护区近海海域整体属于面源污染类型,但整个海域由北到南污染情况略有不同,海域北部偏重于化学污染类型,南部偏重于面源污染类型,分析的结论为该区域的环境监测及污染治理提供了重要的信息和依据.
