Between conflict and coexistence: Wildlife in rubber‐dominated landscapes 冲突与共存之间:橡胶林主导景观中的野生动物
Integrative Conservation, Volume 2, Issue 4, Page 240-254, December 2023., 2023 Natural habitat loss forces some wildlife species to increasingly extend their habitats into farmlands. Rubber‐dominated landscapes surrounding protected areas have the potential to facilitate coexistence between people and some wildlife species if young plants are better protected and plantation management is made more wildlife‐friendly.

Integrative Conservation, Volume 2, Issue 4, Page 201-213, December 2023., 2023 Livestock disturbances decreased the area of suitable habitat of forest pheasants by 14.28% in 7 years. Livestock activities remarkably increased the nest failure rate (by 2.18 times) of forest pheasants. Abstract The degradation and fragmentation of natural habitats, driven largely by anthropogenic activities such as grazing, represent growing ...

Time‐lagged effects of habitat fragmentation on terrestrial mammals in Madagascar
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Biodiversity is severely threatened by habitat destruction. As a consequence of habitat destruction, the remaining habitat becomes more fragmented. This results in time‐lagged population extirpations in remaining fragments when these are too small to support populations in the long term.

Gongye shui chuli, 2021 介绍了唐山某日资机械加工企业采用电絮凝破乳后再生物无害化处理废切削液的工程实例。工程采用电絮凝破乳+批处理对高浓度废切削液进行预处理，处理后的废水直接进入生化系统，出水COD＜300 mg/L。而后上述废水混入生活污水处理系统中继续处理，最终出水COD可稳定在150 mg/L以下。项目2019年8月全部建成，调试交工后运行至今，电絮凝破乳预处理系统及总处理系统运行稳定，出水各项指标可达到《污水综合排放标准》（GB 8978—1996）二级排放要求。

Gongye shui chuli, 2003 采用破乳-Fenton试剂法对机械厂磨床车间废乳化液进行处理(原水CODCr=290000mg／L,BOD5=28000mg／L)。结果表明：使用合适的破乳药剂，破乳后废水的CODCr去除率达到97．8％；之后投加适量的Fenton试剂进行氧化处理，最终出水CODCr为684mg／L；BOD5／COD由0．094增至0．47，可生化性大大提高。

Gongye shui chuli, 2000 乳浊液(通常称之为乳化液)中含有大量的油类和表面活性剂,并以微细的颗粒液珠高度分散在水中,具有相当的稳定性。因此,破乳是处理乳化液废水的关键之所在。以阴离子表面活性剂作乳化剂的O/W型乳化液为研究对象,通过试验,分析乳化液的浓度、乳化液的pH值等因素对破乳的影响。并比较了聚合硫酸铝与聚合硫酸铁的破乳效果,分析了聚合硫酸铁的破乳机理及特性。说明聚合硫酸铁是一种新型高效的破乳剂,值得广泛推广,以利于更经济有效地治理乳化液废水,减少乳化液废水对水体的污染。

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
Integrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

Gongye shui chuli, 2017 针对某机械制造厂机械加工过程中产生的高浓度切削液废水进行破乳预处理试验，比较8种絮凝剂的混凝破乳效果，研究了投加助凝剂聚丙烯酰胺（PAM）以及调节pH对混凝破乳的影响，通过正交试验，综合技术可行性，优选出最佳破乳条件。结果表明，聚合氯化铝（PAC）为最佳絮凝剂；废水加浓硫酸酸析，pH降至6后，PAC投加量为6 g/L，PAM投加量为0.1 g/L，混合快搅5 min，絮凝慢搅5 min，静沉30 min后，废水COD去除率可达61.2%。

Gongye shui chuli, 2005 印刷电路板生产中产生的显影废水是一种高有机物含量、成分复杂、难以生化降解的废水。作者采用酸化破乳—铁炭微电解—中和沉淀—SBR组合工艺处理该废水,并通过实验确定最佳工艺参数:酸化破乳pH为3～4,破乳后出水进入铁炭微电解柱,V(铁)∶V(炭)=1∶1,反应时间为45 min,出水加石灰乳调节pH为7～8,中和沉淀;SBR每12h为一个周期,最佳反应时间为8h。经组合工艺处理后,原废水CODCr由原来的11 000mg/L降至400 mg/L左右,去除率达到96%左右。
