自然保护区旅游开发的生态影响

在自然保护区开发旅游余对其生态景观造成影响，旅游者行为也会对生态系统及其动，植物造成破坏，对大气，水质造成干扰。 云南的自然保护区具有完整的森林自然景观，各具特色的生物生态景观和人文旅游资源。应立足生态旅游，制订发展规划，加强建设和管理，实现自然保护区一的持续发展。     

战略环境评价的几个基本问题

阐述了战略、环境效应与环境影响、战略环境评价等基本概念，分析了战略环境影响发生机理，提出战略环境评价的三种类型，即预测型ＳＥＡ、监控型ＳＥＡ和回顾型ＳＥＡ，并探讨了三类ＳＥＡ的区别和联系。     

微电解处理低电导印染废水及热效应研究

针对低电导印染废水难处理的特点，采用微电解法对该废水进行了实验研究。在电压一定的条件下，通过改变NaCl电解质的投放量，得到处理该废水的最佳工况。同时，从实验现象中得出温度的变化是影响该废水处理效果的因素之一的结论。从热力学理论研究的角度出发，进一步论证了该结论。

Community richness and stability in agricultural landscapes: The importance of surrounding habitats

In this paper, the role played by habitat diversity in the landscape on species richness and on the stability of farmland bird communities was investigated. Species richness was estimated on 374 samples monitored in farmland by the French breeding bird survey during the 2001–2005 period. A capture–recapture approach was used to estimate species richness accounting for the variation in detection probability among species of the 100 most common species detected in farmland. Landscape structure and composition were measured both in farmland and in adjacent habitats. The independent effect of each variable on community richness and stability was further assessed using hierarchical variance partitioning and taking spatial autocorrelation into account. A strong matrix effect was detected: non-cropped land deeply influenced richness and stability of bird assemblages.     

A synergetic model for implementing an integrated management system: an empirical study in China

The implementation and certification of quality, environmental and occupational health and safety management systems have become a priority for many organizations. They are viewed as symbol for success and prerequisite for survival. However, it has been proved to be difficult to operate multiple parallel management systems covering quality, environment, and occupational health and safety and to ensure their alignment with the organization's strategy. To investigate the current status of integrated management system (IMS), a structured questionnaire survey was administrated. It is concluded that the major problems for enterprises to operate multiple parallel management systems include: it causes complexity of internal management, it lowers management efficiency, it incurs cultural incompatibility, it causes employee hostility, and increases management costs. The survey also examined the internal and external factors that affect the implementation of IMS. The internal factors include: (1) human resources, (2) organizational structure, (3) company culture, and (4) understanding and perception. The external factors consist of: (1) technical guidance, (2) certification bodies, (3) stakeholders and customers, and (4) the institutional environment. The article proposes a multi-level synergy model (strategic synergy, organizational structural-resource-cultural synergy, and documentation synergy) for an effective implementation of IMS.     

规模化牲畜养殖场的环境效应及其对策

通过对江苏省2个典型地区的4个生猪养殖场的饲料、牲畜排泄物、土壤、地表水及水土水中养分状况的调查采样与分析，对牲畜规模养殖的环境效应进行了评价。在此基础上，对牲畜养殖排泄物的养分管理与资源化利用提出了建议，并通过对牲畜排泄物中养分状况及作物养分需求状况的分析统计，提出了种植－养殖区域养分平衡管理模式。

裂变产物170Tm的体内蓄积特性诱发骨髓细胞突变效应研究

对裂变产物~(170)Tm的体内蓄积特性和诱发细胞突变效应的监测结果表明,当机体摄入~(170)Tm后,在短时间内即能迅速进入并滞留于骨组织中,其滞留量占体内各器官组织中的首位呈现高度选择性亲骨特征,在机体摄入~(170)Tm后的不同阶段,骨组织中的累积吸收剂量随着观察时间的延长而增升,其诱发骨髓细胞的染色体畸变率亦相应增高。由~(170)Tm内污染所诱发的染色体结构异常为染色单体型畸变,其中主要为染色单体断裂。随着骨组织中累积吸收剂量的增升,可观察到在一个细胞中同时有两个畸变发生,也诱发个别的染色体易位。
