延庆地区的湿地保护

1湿地的定义及其沿革 对许多人来说,湿地是一个十分生疏的的概念,只是近年来,随着环境问题的突出,人们开始关注湿地."湿地"一词源自英文Wetland,是对地球三大生态系统(海洋、湿地与森林)中的与水发生关联的生态系统的总称.例如无论是天然或人工的湖泊、沼泽、滩涂、水库、蓄洪区、鱼塘、芦苇荡、荷花淀、烂泥坑……更大一些的有海滩、泛洪平原,只要水深不超过6 m的水域,无论咸淡,一律被称做湿地.     

留住历史记忆 保护特色建筑文物

历代古典宫殿、教堂、寺庙、宗祠、园林、民宅以及桥梁古道,无论是雕龙画凤,还是斗拱飞檐等古法神工,越是历经风雨沧桑,沉积下来的"宝光"就越浓!一切古建筑文物都无不反映当时政治、经济、文化以及民风习俗的兴衰,无不体现我们先民的勤劳、智慧、心血和汗水,应该说,古建筑就是一部教科书,它记录了历史的文明与兴衰,寄托了人类的思想与灵魂的变迁。众所周知,人类在不断改造自己,推动社会发展的文明进程中,无论是帝王将相、才子佳人,还是文人墨客、富商豪爵,上到天官重臣,下至庶民百姓,学文习武,生活劳作都会受到古建筑古色、古香、古气陶冶。     

城市,让生活更美好——聚焦湖北“城管风暴”——大气魄，大手笔，大变化——武汉市“城管革命”成效初显

城管,是城市管理监察部门的简称,是城市管理的综合执法组织。城管的职责包括市容环境卫生、违法建设处罚、违法占路处罚、无照经营处罚、城市节水管理、停车管理、园林绿化管理、施工现场管理、拆迁工地管理、城市河湖管理、＂黑车＂管理……总之,城管＂无所不管＂,肩上的责任相当重大,然而,由于职权不清、相关部门之间缺乏配合、执法观念滞后等原因,城管执法往往治标不治本,甚至激化了矛盾。

浅析如何发挥财务管理的职能

一、发挥财务管理的决策职能,做好企业资金的筹措、投放和运营等工作,促进企业良性运行1．资金筹措决策。资金筹集的主要渠道有:国家财政资金、银行信贷资金、非银行金融机构资金、其他企业资金、民间资金、企业自留资金、外商资金。可以采取的筹资方式有:吸收直接投资、发行股票、银行借款、商业信用、发行债券、发行融资券、租赁筹资。不同的筹资渠道和筹资方式,有不同的契约条件、偿还期限、报酬支付方法,也有不同的使用代价,对利润也会产生不同的影响。财务人员及其决策者,必须把握不同筹资渠道和筹资方式的关系,综合考虑企业的经营状况、财务状况、资本结构、资金成本、投资风险等因素,在众多的组合方案中,通过定性分析与定量分析相结合的方法,选择适合本企业发展的最佳方案,以期获得结构优化、配置合理的资本结构,为企业取得最大的经营利润打基础。

Deformation of the rock foundation of the Bratsk hydroelectric station

Conclusion Deformations of the rock foundation of the Bratsk dam occurred mainly during filling of the reservoir and primarily due to the weight of the water operation. During operation, settlements have increased insignificantly with a clear tendency toward their fading away. The maximum settlement, 74 mm, which had been predicted as early as 1966, was reached in 1970; in 1977 it amounted to 74.4 mm. Horizontal deformations have practically stabilized. At the base of the dam, if slight consolidation occurred at all during construction (which, apparently, caused mainly differential settlement of the sections), then it was hardly noted by observations. Despite the explicit stabilization of the processes, observations of settlements and horizontal displacements retain their importance, considering the essential character of the structures, the seismicity of the region, and the slowness of processes characteristic for hydraulic structures. The geodetic base of the Bratsk hydrostation has certain shortcomings: the bench marks are located on a diabase sheet and can settle along with it; the nearness of the diabase rock quarry to the right-bank bench marks; the rather long and complex traverse along the foreshores. Use of the geodetic base is also difficult: the traverses along the foreshores are difficult and dangerous owing to the adjacent high (up to 80 m) steep cliffs, the natural disintegration of which causes rock falls. We consider that it would be more convenient and reliable to embed bench marks with anchors in sandstones below the upper zone of consolidation (depth 100–120 m) in the bank tunnels of the inspection gallery at the 27-m level.

江垭水电站地下厂房岩锚吊车梁岩台开挖

岩锚梁的岩台开挖是岩锚梁施工的关键技术，施工时，不仅要确保岩台在开挖过程中的稳定，而且也要确保岩台开挖前后的稳定，同时还要确保在后序开挖过程中不对已浇筑的岩锚梁自身结构的稳定性产生影响。江垭电站的岩锚梁施工，以工程地质体制论为理论基础，岩台开挖分４步进行：第１步在岩台以上２ｍ范围内进行预裂爆破；第２步进行岩面光面爆破；第３步在岩台以下２ｍ范围内进行预裂爆破；第４步在第３开挖层进行预裂爆破。岩台开挖

Classifying Sea Lamprey Marks on Great Lakes Lake Trout: Observer Agreement,Evidence on Healing Times between Classes,and Recommendations for Reporting of Marking Statistics

In 1997 and 1998 two workshops were held to evaluate how consistent observers were at classifying sea lamprey (Petromyzon marinus) marks on Great Lakes lake trout (Salvelinus namaycush) as described in the King classification system. Two trials were held at each workshop, with group discussion between trials. Variation in counting and classifying marks was considerable, such that reporting rates for A1–A3 marks varied two to three-fold among observers of the same lake trout. Observer variation was greater for classification of healing or healed marks than for fresh marks. The workshops highlighted, as causes for inconsistent mark classification, both departures from the accepted protocol for classifying marks by some agencies, and differences in how sliding and multiple marks were interpreted. Group discussions led to greater agreement in classifying marks. We recommend ways to improve the reliability of marking statistics, including the use of a dichotomous key to classify marks. Laboratory data show that healing times of marks on lake trout were much longer at 4°C and 1°C than at 10°C and varied greatly among individuals. Reported A1–A3 and B1–B3 marks observed in late summer and fall collections likely result from a mixture of attacks by two year classes of sea lamprey. It is likely that a substantial but highly uncertain proportion of attacks that occur in late summer and fall lead to marks that are classified as A1–A3 the next spring. We recommend additional research on mark stage duration.

Impact of Incision of Gravel‐bed Rivers on Ground Beetle Assemblages

The impact of river incision induced by channelization and gravel mining on the structure of ground beetle assemblages in riparian habitats was investigated on three montane rivers in southern Poland. Ground beetles were collected on three benches of different elevation in 11 incised and 14 vertically stable cross sections of the rivers. In total, 5821 individuals representing 106 species were collected. The effect of river incision on the diversity and abundance of ground beetles depended on bench height. Only on the lowest bench, inundated about once per year on average, species richness of the assemblages was significantly reduced in incised river cross sections. On this bench, the abundance of the specialists of exposed riverine sediments, i.e. small and medium‐sized predators with high dispersal power and spring breeding strategy, was highly negatively affected by river incision. On the highest bench, large, brachypterous species with spring and autumn breeding strategy, typical of undisturbed habitats, were more abundant in incised cross sections. As this bench is practically not subjected to flooding even in vertically stable cross sections, these species probably benefited from the occurrence of riparian forest along most incised river sections, whereas the riparian areas along vertically stable sections are subjected to higher agricultural pressure. This study shows that in the mountain region where high precipitation helps to maintain moisture of the riparian habitats, river incision has a negative impact only on the specialists of exposed riverine sediments.
