江苏省泰兴市土地资源的人口承载量研究

从人群的营养水平和主粮、副食品消费结构的变化出发，分别估算和预测了１９９３年和２０００年江苏省泰兴市土地资源的人口承载量。结果表明，该市土地资源１９９３年可供１２０万人过上宽裕型生活，到２０００年可供９５万人过上小康型生活，其余三分之一以上人口的粮食需求要依靠市外供给。     

无锡新区生态工业链网设计探讨

生态工业园区是按照工业生态学原理，通过模拟自然生态系统，建立工业系统中“生产者-消费者-分解者”的循环途径，实现物质闭路循环和能量多级利用。文中介绍了生态工业园区的概念、分类和中国工业生态园区的建设进展。结合无锡新区生态工业园区的建设现状，提出新区的生态工业链网设计思路，通过园区成员企业之间的协同管理，以取得资源、环境与经济、社会效益的增长最大化。     

Results from the first year of the Swedish dioxin survey

PCDD/F levels are presented for food baskets, raw and fried herring, wolf muscle and moose tallow collected from the same area, three burbot liver samples, a sediment core from the Baltic Sea and leach water from three garbage dumps. Levels in food baskets were at or below detection limits making the estimation of intake via the diet difficult. Frying herring produces no net change in PCDD/F levels. Moose have lower PCDD/F levels than wolf from the same area. Levels in burbot liver samples are much higher near industrial discharges than in a more undisturbed area. The top 4 cm of the sediment core contain the highest levels of PCDD/F. Thereafter the levels drop and reach a low level. This low level is probably caused by contamination during sampling and is not evidence of PCDD/F presence far back in time. Leach water from city dumps contains low levels of PCDD/F but that from a dump that takes industrial wastes had higher levels and a different congener pattern.     

铅锌冶炼行业循环经济产业链构建

运用循环经济理论,以某铅锌冶炼企业为例,在分析企业能流、物流的基础上,研究了企业的循环经济发展潜力,提出了铅锌冶炼行业"冶炼-制酸-发电-贵金属回收"的循环经济发展产业链模式.研究结果表明,通过构建铅锌冶炼企业循环经济产业链,可以提高企业的资源利用效率,降低能耗和生产成本,减少污染物的排放,获得显著的经济效益和环境效益.     

中国有机食品的研究与发展前景

介绍了有机食品的基本概念和有机食品所应具备的条件，并比较了有机食品与绿色食品的区别与联系；在对国内外有机食品的发展概况和中国发展有机食品的有利条件的全面论述和分析的基础上，阐明了中国有机食品的发展不仅有着良好的国内外市场，而且有着广阔的前景。     

中国食品中B(a)P污染和控制

本文总结了近十几年来我国城市蔬菜等食品中B(a)P污染的调查结果,表明随着大气污染的加剧以及工业"三废”排放的增大等,B(a)P在食品中的残留污染已不容忽视,具有面源污染的特点.探讨了蔬菜等食品受B(a)P污染的影响因素,提出了食品中B(a)P污染的控制方法.     

Space-time modeling for the Missouri Turkey Hunting Survey

The Missouri Turkey Hunting Survey (MTHS) is a postseason mail survey conducted by the Missouri Department of Conservation. The 1996 MTHS provides information concerning the number of turkeys harvested by hunters on each day and the total number of trips made to the counties by these hunters on each day of the hunting season. The success rates are then found from this information. Small sample sizes produce large standard errors for the estimates at the county level. We use a Bayesian hierarchical generalized linear model to estimate daily hunting success rates at the county level. The model includes an autoregressive process for the days of the hunting season and spatially correlated random geographic effects. The computations are performed using Gibbs sampling and adaptive rejection sampling techniques. Results show that there are significant spatial corelations between counties and correlations between days of the hunting season. The estimates are close to the frequency estimates at the state level and much more stable at the county level.     

丝瓜对食品废水的净化功能及经济效益

本文研究了丝瓜（Ｌｕｆｆａｃｙｌｉｎｄｒｉｃａ）在水面上的水培技术，对食品工业废水（啤酒废水）的净化功能及其经济效益。其试验结果表明：采用水培技术将丝瓜栽种在水面上是完全成功的。该法已经被应用到无锡市酿酒总厂食品工业废水净化处理。在５月份，丝瓜对啤酒废水中污染物ＴＮ的净化率为７８．６％，ＴＰ７８．０％，ＮＨ＋＿４－Ｎ９９．６％，ＣＯＤ２２．５％，浊度８０．９％。在６月份，丝瓜的净化率为ＴＮ８９．１％，ＴＰ９０．４％，ＮＨ＋＿４－Ｎ９９．２％，ＣＯＤ４４．１％和浊度８６．４％。由此可见，丝瓜是一种对食品废水净化的优良植物，其经济效益也很显著，每亩水面丝瓜（果实）可达２０００ｋｇ～２５００ｋｇ，经济价值达２０００元～２５００元。     

中国穿山甲的食性与觅食行为初步观察

通过野外观察及粪便和胃内容物分析,对中国穿山甲的食性进行了调查和研究.结果表明,中国穿山甲的觅食行为可分为6个类别,即行走、搜寻、行走/搜寻、挖掘、取食、暂停;取食地点主要发生在杂草、乔木、灌木的基部,落叶层下,倒木/枯枝、死树桩附近及白蚁巢内;以蚁类为食,且表现出明显的选择和偏爱,被拒食的蚂蚁和白蚁种数分别占83.87%(26/31)和53.85%(7/13),最喜爱的蚁类是台湾乳白蚁(Coptotermesformosanus)、黄翅大白蚁(Macrotermesbarneyi)、双齿多刺蚁(Polyrhachisdives);食谱由11种蚁类构成,占大雾岭保护区蚁类组成25%,其中蚂蚁5属5种,白蚁4属6种,夏季食谱主要由蚂蚁构成,冬季食谱主要由白蚁构成,台湾乳白蚁、黄翅大白蚁很可能是穿山甲食谱中的关键食物.表6参25     

浦东新区土壤—食物链中的铜锌

本文调查了浦东新区污灌区、吹泥区和一般区三种处理土壤中Ｃｕ、Ｚｎ的水平和垂直分布，Ｃｕ、Ｚｎ分层现象不明显，水平差异较大，但三种关型土壤差异不显著。Ｃｕ在食物链中累积系数铰小，一般小于１．０，而Ｚｎ的累积程度较大，尤其是以人为消费者的食物链中，累积系数最高达到１８。
