环境污染事故危险源评级方法研究

将环境污染事故危险源分成空气污染型和水体污染型两大类,并考虑危险源自身特性和周围环境状况两个主要因素对两类危险源分别提出了评级模式,依据危险指数大小将危险源分为特大、重大、较大和一般四级;利用试点调研的63家企业的183个危险源数据,对危险源评级模式进行了参数选定和验证,证明所建议的方法和模式是可行的,可供危险源调研和建立数据库等实际工作应用。     

Study on the effect of porous fence on air quality and traffic noise level around a double-decked road structure

Fence for traffic noise control sometimes causes adverse effect on air pollution. Thus in this study, performance of porous fence as a tool for control of both air pollution and noise pollution was evaluated. A two-dimensional numerical model for flow and pollutant concentration and an analytical model for traffic noise were utilized in the analysis of a double-decked road structure with fences only at ground (Case 1) and at both ground and upper deck (Case 2). Porous fences were assumed only at the ground level since the solid fences at the upper deck usually leads to desirable result on air pollution. Effects of the variable porosity on air quality and noise level near road were evaluated. Obtained results showed: (1) flow pattern in leeward of fence was drastically changed at 40–50% porosity in Case 1 and 50% in Case 2. The porosity larger than 40% excluded presence of a circulation behind the fence. (2) Effect of porous fence on air pollution was different in Cases 1 and 2. In Case 1, the porous fence generally resulted in the reduction of air pollution at the ground level; on the other hand, in Case 2, it rather led to increase of the concentration. (3) Traffic noise level was also largely changed by the porosity of the fence; an example of simultaneous evaluation of the effects of porous fence on both air and noise pollution in Case 1 showed that the fence of 60% porosity leads to reduction of air pollution by 20% compared with solid fence case, and reduction of noise pollution by 4–6% in dB compared with no fence case, at l m high and 10 m from the road.

厂房、办公楼租赁、转让的环境保护问题

随着市场经济的迅速发展，大量厂房办公楼租赁、转让产生新类型的环境问题。由于其具有突发性、隐蔽性、难追究、治理难的特点，因而应将合同(契约)等重要经济环节纳入环境约束，加强管理，切实实施。     

试论移民对生态环境与社会经济环境的影响--以湖南省涔天河水库扩建工程为例

库区移民会对当地森林植被、野生动物、水土流失、水体污染和城镇环境、农村聚落环境等造成影响。为此，必须从制订环保规划、保护森林资源、防止水土失流，解决移民粮食问题等方面采取对策。     

南汀河流域生态环境特点及其保护

南汀河流域水土流失严重，洪涝灾害频繁，可耕地少，且上游植被稀少。应采取切实措施提高森林覆盖率，制止不合理人为活动对水土保持的破坏，推进清洁生产，提高环境意识，改善和保护流域的生态环境。     

遥感调查方法在河北省省级自然保护区生态环境变化评估方面的应用研究

河北省省级自然保护区以自然生态系统类型为主,人类活动较为频繁,将遥感评估方法应用于河北省省级自然保护区生态环境变化评估具有重要意义。本文通过分析高分辨率遥感卫星影像的特点,结合河北省省级自然保护区的实际情况,优先选取分辨率为2m的民用卫星,提出了遥感调查方法在自然保护区人类活动和开发建设活动中自动监测、生态系统格局变化、生态系统质量变化以及人类活动干扰程度四方面的评估应用。     

城市生态休闲绿地建设研究

城市生态休闲绿地不同于城市绿地,主要包括其中的城市公园绿地和其他绿地。结合市民平时主要在居住地附近散步、节假日喜欢到郊区游憩的休闲活动特点,把生态休闲绿地分为日常短时休闲绿地和节假日长时休闲绿地。在城市生态休闲绿地建设中,应重点建设日常短时休闲绿地,配套开发节假日长时休闲绿地,完善城市公共绿地的休闲设施,增强城市公共绿地的大众性,提高专有绿地的开放性。     

浅谈秦皇岛外语语言软环境的优化策略

秦皇岛作为著名的沿海旅游城市,外语语言环境作为旅游软环境的一个重要因素直接影响着整个旅游产业的综合竞争力。鉴于此,对秦皇岛市外语语言软环境进行调查摸底。调查结果表明,旅游景区标示语及城市公示语的翻译存在不同程度的问题,旅游从业人员总体素质不高,市民的外语能力普遍偏低。以调查结果为依托,从政府导向、行业把关、全民参与三方面提出了优化秦皇岛市旅游业外语语言软环境的建议。
