节能认知的“单效偏见”

＂随手关灯＂这句＂名言＂,警示了我们几代人,一说起节约用电,很多人都会想到随手关灯。但在前不久上海的一次节能宣传活动上,专家却告知参观者：＂随手关灯,未必节能。＂     

李克强：动员全民力量 推动能源节约

Microbiological parameters and maturity degree during composting of Posidonia oceanica residues mixed with vegetable wastes in semi-arid pedo-climatic condition

The aim of this study was to characterize the biological stability and maturity degree of compost during a controlled pile-composting trial of mixed vegetable residues (VR) collected from markets of Tunis City with residues of Posidonia oceanica (PoR), collected from Tunis beaches. The accumulation in beaches (as well as their removal) constitutes a serious environmental problem in all Mediterranean countries particularly in Tunisia. Aerobic-thermophilic composting is the most reasonable way to profit highly-valuable content of organic matter in these wastes for agricultural purposes. The physical, chemical, and biological parameters were monitored during composting over 150 d. The most appropriate parameters were selected to establish the maturity degree. The main result of this research was the deduction of the following maturity criterion: (a) C/N ratio < 15; (b) NH₄⁺-N < 400 mg/kg; (c) CO₂-C < 2000 mg CO₂-C/kg; (d) dehydrogenase activity < 1 mg TPF/g dry matter; (e) germination index (GI) > 80%. These five parameters, considered jointly are indicative of a high maturity degree and thus of a high-quality organic amendment which employed in a rational way, may improve soil fertility and soil quality. The mature compost was relatively rich in N (13.0 g/kg), P (4.74 g/kg) and MgO (15.80 g/kg). Thus composting definitively constitutes the most optimal option to exploit these wastes.     

Effects of sediment dredging on water quality and zooplankton community structure in a shallow of eutrophic lake

Effects of suction dredging on water quality and zooplankton community structure in a shallow of eutrophic lake,were evaluated.The results showed that a decreasing trend for levels of phosphorus,organic matter,total suspended solids,Chlorophyll a and Secchi transparency in the water column was found,while levels of water depth,electrical conductivity,total dissolved solids and NO 3--N concentration increased markedly post-dredging.The effects of dredging on dissolved oxygen,pH value and temperature were alm...     

近50a来三亚鹿回头石珊瑚物种多样性的演变特征及其环境意义

2005～2006年三亚鹿回头珊瑚礁现状调查共记录石珊瑚13科24属69种,礁坪以滨珊瑚占绝对优势(重要值百分比>50%),礁坡以鹿角珊瑚最占优势(28.33%).Pielou、Simpson和Shannon-Wiener多样性指数值均高于礁坪.对比历史资料发现近50 a来该岸段珊瑚礁呈衰退趋势:七世纪五六十年代该岸段珊瑚种类繁多、群落垂直分带,生物多样性较高;20世纪七八十年代礁坪已不见成片的活珊瑚,礁坡繁茂程度降低;20世纪90年代珊瑚种类虽仍比较丰富,但总体多样性下降;本次研究显示澄黄滨珊瑚已成为礁坪优势种,鹿角珊瑚在礁坡的优势度降低,物种多样性继续缩减.过度捕捞、大规模挖礁、海上和沿岸养殖等人类活动是造成该岸段珊瑚礁现有衰退的主要原凶,三亚河和近海上程建设带来的泥沙和污染物以及正向鹿回头扩展的潜水旅游可能是影响其发展的潜在威胁.     

"我们就是专门挑刺儿的"

1月9日9时15分,山东淄博当地气温零下10摄氏度,中雪。 冰天雪地里,齐鲁石化HSE督察小组的段海涛正喘着粗气,跟供排水厂水井上的一个仪表箱“较劲”。他左手顶住仪表箱,右手拽住箱门把手,用力一拉,箱门纹丝不动。回头看了看搭档刘新猛,他嘟囔了一句,“看来是锁好了”。刘新猛说：“再试一下”。段海涛重新活动了几下把手,再次发力——仪表箱门仍然没有打开。
