从日本节能中心的《工厂调查报告书》看节能监测的必要性

能源是国民经济和社会发展的重要物质基础，能源短缺已成为制约人类社会发展的重要问题。节约能源是国家和政府一项长远的战略方针，是促进和保持经济持续发展、快速增长、企业经济效益稳步提高的重要手段。《天津市节能监督检测管理办法》已以天津市人民政府令第70号发布施行。该《70号令》要求“本市行政辖区内生产、生活用能的企、事业单位、机关、团体和个人均应遵守本办法”。耗能企业特别是重点用能单位必须认真对待这项工作和问题。本从日本节能中心的几位专家通过对天津大沽化工厂有限责任公司进行节能潜力调查后所的《工厂调查报告书》入手，通过该《报告书》中述及的有关实例，说明企业节能管理中存在的问题和节能潜力，进而论述政府对企业实施节能监测的必要性。

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

某煤矿地面工业区噪声污染浅析

煤矿的噪声污染主要分布在矿井下和地面工业区，以往人们仅重视井下噪声污染，而忽视了地面工业区的噪声污染。本次对地面工业区噪声污染的调查结果显示，地面工业区噪声源相对集中，车间内外噪声较高，但对居住区基本不构成危害     

Vegetation patterns and nature reserve construction in an extremely-arid desert in Anxi,NW China's Gansu Province

Anxi County is located in the northwestern part of the Hexi Corridor in gansu Province and has the sole national level nature reserve of extremely-arid desert in China.Phytosociological methods (Braun-Blanquet,1964) are used to classify plant community types in this area.Eleven are disting uished,including six of deserts,four of oases and one transitional type between deserts and oases.Direct gradient analysis (DCA) is employed to correlate the distribution of plant communities to physiogeographic conditions.This study makes clear that water is the most important ecological factor for the distribution of plant species and communities in this area.The effects of water have been demonstrated in different ways.A vegetation gradient from lower altitude to higher altitude in the southern part of the reserve is driven by a precipitation gradient.The effects of the depth of ground water table contribute to the differentiation of vegetation from desert to oasis in the flat area.In a finer scale,the washed gullies have obviously higher species richness and also higher vegetation cover than the surround gobi surfaces,possibly caused by the effects of floods.The vegetation patterns demonstrate that the area of Anxi County is a complete landscape unit.The range of the current nature reserve is not large enough for the purpose of conserving the unique biodiversity in this area.
