江苏省盐城市环境空气质量综合评价及整治对策

随着经济发展的加速,盐城已逐步融入长三角经济体系中,城市现代化建设正在大踏步向前迈进,城市生态环境问题也日益受到关注,生态环境问题已成为社会关注的焦点,是衡量盐城社会经济发展的重要指标,实现环境、经济、社会的和谐发展已逐步成为人们的共识.文章针对盐城环境空气质量问题,运用SO2、NO2和PM10等指标表示空气环境质量,采用模糊综合评价方法对盐城空气环境质量等级进行了划分,并采用API指数评价方法对污染程度作出了评价,分析了盐城环境空气质量面临的挑战,提出了盐城市区污染的防控措施.     

模糊数学在室内空气质量评价中的应用

随着生活水平的提高和生活方式的改变,人们在室内生活的时间越来越长,室内空气质量的优劣直接影响到人们的工作和生活.尤其是近年来,出现了大规模的装修热,因此而引起的室内空气污染问题也日益突出.为了能够更客观直接准确的反映出室内空气质量好坏,本文依据国家标准GB/T18880-2002中的标准值,将空气质量分为五个等级.并根据模糊数学的基本原理,选取评价因子,建立室内环境质量模糊综合评价隶属函数,确定了模糊矩阵,把它应用于室内环境质量的综合评价中.

基于模糊相似关系的土地资源空间分布系统递阶结构模型

建立了土地资源多层次分类体系及分类子体系，用模糊相似矩阵描述了系统各单元的相关关系，通过λ截集矩阵的选择使之转化为表征系统是否相关的０－１矩阵，从而对系统结构模型予以改进，并应用该模型进行土地资源的递阶分类，实现了区域土地资源在地域空间合理分布。     

Exploring the Theoretical Interface of Climate Change and Resource Dependency: Application to the Vulnerability of Boreal Forest Regions

This paper addresses the combined effects of two sources of disturbance on the boreal forest – climate change and the economic relations of industrial forestry. It describes a theoretical blueprint constructed of concepts from the theory of dissipative structures (derived from the discipline of physical chemistry) and world-systems theory (derived from the discipline of sociology) into a proposed integrated theory pivoting on the concept of social vulnerability. The goal is to examine the key concepts of this theory – vulnerability, resilience and adaptive capacity – as elements of the complex systems perspective provided by dissipative structure principles. The focus on social vulnerability provides the means to establish the role of external economic linkages relevant to industrial forestry – the core/periphery relations of the world-system – as they influence the social vulnerability of the boreal forest SESs. These systems are posited as embedded peripheries, following world-system criteria, and as the focal scale of analysis within a larger hierarchically organized dissipative structure. The goal is to suggest and stimulate ideas for further discussion and exploration, motivated by the premise that any successful climate change mitigation efforts depend on having sound theoretical foundations on which to stand.     

非线性灰色模型在污染物总量预测中的应用

在前人工作的基础之上介绍了几种修正的ＧＭ（１，１）非线性模型，并以衡阳市１９９０～１９９６年城区污染物总量（ＣＯＤ）的预测为例，探讨了各种模型的应用效果。结果表明：非线性模型的拟合精度更高，具有更加广阔的发展前景。     

多环芳烃的分配系数与双区理论

以双区理论为基础,提出了多环芳烃的致癌性与其分配系数之间的定量关系方程,并利用该方程计算了77个多环芳烃的致癌性。计算值与实验值基本符合。     

多级模糊模式识别方法用于湖泊水质评价

进行模糊综合评估的应用与研究很多，在那些方法中主要应用最大隶属度原则进行最后的评定，但是湖泊水质评价涉及到多样点多项指标等多因素，一般模糊综合评价方法中的最大隶属度原则不能适用。本文利用多级模糊模式识别方法的基本理论，通过多目标优选，给出了更加合理、科学的评价模型；利用该模型我们对武汉市东湖水质监测结果做出了较为合理的评价。     

Optimizing the atmospheric sampling sites using fuzzy mathematic methods

A new approach applying fuzzy mathematic theorems, including the Primary Matrix Element Theorem and the Fisher Classification Method, was established to solve the optimization problem of atmospheric environmental sampling sites. According to its basis, an application in the optimization of sampling sites in the atmospheric environmental monitoring was discussed. The method was proven to be suitable and effective. The results were admitted and applied by the Environmental Protection Bureau (EPB) of many cities of China. A set of computer software of this approach was also comuletelv comniled and used.
