乌鲁木齐城市灾害特征及减灾对策

论述了乌鲁木齐城市灾害的主要类型，特征，成因及经济损益分析，并就减灾问题提出预防对策，乌鲁木齐市地处欧亚大陆的中心，东，南，西三面环山，北面是广阔的冲积平原；复杂的地质，地貌和地形，多变的气候，加上脆弱的生态环境，为各种灾害的发生提供了重要条件，乌鲁木齐每年都不同程度地发生各类灾害，随着城市人必集和社会发展，生命线工程，城市基础设施和社会财富的增加，城市灾害所带来的损失和灾难将会以更大的比例增长，因此，研究如何防御和减轻自然灾害和人为灾害对城市的破坏，已成为一个重大的社会问题。     

神农架森林火灾发生率的长期预报

通过对神农架林区１９７０－１９９１年的森林火灾资料和前期青藏高原月平均气温的相关分析，建立该区３－５月林火发生率的长期预报统计模型，经１９９２年和１９９３年的实况验证，预报效果良好。     

论城市火灾的气象分析预报─—以金衢盆地两城市为例

通过对金华、衢州两市大灾发生情况的统计分析，揭示城市火灾发生与当地气象因子之间的相关关系，试图通过了解空气湿度、水汽压、降水量、蒸发量等气象因子的变化，对城市未来火灾发生情况作出预报，以便采取相应的预防措施。

喀斯特山区火灾迹地自然与人工恢复效益

针对桂西北喀斯特山区森林火灾频繁、火灾迹地面积大，森林生态系统退化严重，选择该地区5种主要造林林种及造林方式和自然抛荒恢复模式，分析和评价了各种模式的生态系统结构和效益。结果表明，随着经营年限的增加，6种经营模式土壤肥力、生物生产力都明显提高；水土保持最好的是自然抛荒恢复，其次是人工竹林和人工油菜，较差的是人工马尾松和人工桉树；投资效益除自然抛荒模式外，最高的是人工油菜和人工木荷，其次为人工桉树和人工马尾松，较差的是人工竹林。     

Impact of forest fires on regional air quality in Southeast Asia

Biomass burning, the burning of living and dead vegetation for land-clearing and land-use change, has been in practice in many tropical countries such as Brazil, Indonesia, Nigeria, and Mexico. Intense forest fires can also ignite subsurface organic soil components （e.g. peat）, which can continue to smolder long after the original surface fires are put out. Combustion of vegetation and peat has only recently been recognized as a major source of atmospheric pollution. The immediate effect of burning is the production and release of gases and particles into the atmosphere, in quantities that in some cases can be significant not only locally and regionally but also on a global scale. Vegetation fire emissions account for roughly half of the atmospheric constituents of hydrocarbon, carbon monoxide, nitrogen oxides, and precursors of tropospheric ozone and may be the second largest source of anthropogenic aerosols after the production of sulfates from SO2. As a result, there has been considerable interest in studying the contribution of forest fires to the production of air pollutants. In recent years, Southeast Asian countries have been affected repeatedly by episodes of smoke haze from forest fires in Indonesia. During 1997-1998, the region was again shrouded in a haze worsened by prolonged drought linked to the E1 Nino weather phenomenon. Satellite pictures confirmed that air pollutants, originating from fires covering an estimated 800000 hectares of southern Kalimantan, Sumatra, and Java, have been transported by southwesterly monsoon winds across neighbouring Malaysia and Singapore to as far as Thailand and the Philippines. The impact of these extensive fires on the health of the residents and ecology in the affected areas was substantial, costly, and possibly long lasting. Most of the research on the environmental aspects of biomass burning has been directed towards the tropics in Africa and America, specifically to the tropical rain forests of Brazil and to the savannas of Africa and South America.     

武汉市火险天气等级标准初探

通过对武汉市1980～1991年逐日火灾与气象资料的相关分析,发现火灾率与相对湿度呈负相关,与气温日较差、连旱天数、最大风速呈正相关,与当天降雨量不相关。通过权重系数法分季建立火灾率多因子综合预报方程,并制订合理的火险天气等级划分标准。经回代和试报检验表明,3级以上中、高火险日数少,但对火灾概括率高。
