Adapt to New Normal State of Environmental Protection,Fight a Tough Fight,and Make Full Efforts to Build a Beautiful Xi'an

In China, economic growing speed converts from high speed to moderate and high speed; economic structure enters from moderate and low end to moderate and high end; development power converts from investment drive to innovation drive, and investment of resource and environ- ment factors presents declining trend. Spatial pattern of economy development is changing greatly, which needs eco-civilization construction and en- vironmental protection field continuously adjusting focus, environmental rules and laws correspondingly regulating, eco-civilization construction and environmental protection field also entering into new normal state. It requires scientifically understanding, actively adapting to and responding to new normal state of eco-civilization construction and environmental protection,and fighting a tough fight. Firstly, we should handle with the relationship between environment and economy, and strive to explore the way of environmental protection. Secondly, we should insist protection priority and prevention oriented,and promote transformation of environmental management strategy. Finally, we should accelerate to promote eco-civilization system reform and environmental protection management system reform, and further promote environmental protection work in Xi＇an on new level from eight aspects.

The environment of coal mining areas and the economic evaluation of the land reclamation

The environment impact of the coal resources mining was analyzed. The method of economic evaluation for the coal mining was established to analyze land destruction. The opportunity cost method was used to quantitatively analyze and estimate the economic loss of the land destruction by coal mining. At the same time, the dump land reclamation of the Yuanbaoshan Open Pit was taken as an example to evaluate environmental and economical benefit with the method of economic evaluation for the coal mining areas land reclamation.

Dynamic Model for Evaluation of Risk Factors During Work in Hot Environment

Mathematical model is developed for prediction of physiological changes in man during work in hot environment taking into consideration intensity of work, clothing and environment. To evaluate human functional state the heat stress index was calculated. Modeling researches made the conclusion that the main risk factor during work in hot environment is water losses that happens through thermoregulatory sweat evaporation. Modeling showed that in humid environment man wearing protective clothing has short time to work as water losses became more than 2% of human weight that means body dehydration. Preliminary model prediction can be used as preventive method to avoid hazard of human health.

Assessment tools of nursing work environment in magnet hospitals: A review

In the 1990s,the American Nurses Association established a certification program called the Magnet Recognition Program through the American Nurses Credentialing Centre(ANCC)to complement the quality care provided to patients by hospitals.After the program was recognised,hospitals were identified as magnet hospitals[1].Some studies show that magnet hospitals provide a healthier working environment for nurses,accompanied by higher nurse satisfaction and better patient prognosis than non-magnet hospitals[2e5].The nursing work environment is the sum of various elements that directly or indirectly affect the patient care system[6].Improving the nursing work environment is a focal point and challenge for nursing administrators.Therefore,administrators in magnet hospitals usually apply a variety of assessment tools for effective evaluation of the nursing work environment to maintain and improve the health of the environment.

PERMAFROST CHANGES AND ENVIRONMENTAL PROBLEMS ALONG THE QINGHAI－XIZANG HIGHWAY

The Environment of permafrost region along Qinghai-Xizang highway has been interfered and damaged seriously during the last years by mankind economic activities. Permafrost under the roadbed has been degenerated obviously. Tank range has been extended gradually and original natural environment around it has been damaged. The mileages of highway crossing the permafrost region today are shortened 18km than that of the 70's. In this paper, according to ice content, class of permafrost. relief and landforms etc., permafrost region along the highway and comprehensive evaluation zonation have been made. And specific measures for protecting the permafrost environment has been put forward.

石油石化企业ESG评价对标及对中国企业的启示

环境保护、社会责任和公司治理(ESG)是用来评估企业可持续发展的重要指标。全球ESG评价体系正在蓬勃发展,普遍采用金字塔结构的ESG评价指标体系模型。采用彭博ESG评价数据库,选取2023年《财富》世界500强排名靠前的23家石油石化公司,对标分析2023年度的ESG表现。23家石油石化公司2023年环境保护维度方面的评分呈现较明显的两极分化现象,社会责任维度中各地域公司评分情况较为均衡,欧美公司在公司治理维度评分普遍较高。中国公司的指标披露力度和深度不足,环境保护指标实际表现不佳,战略及风险分析深度不足,公司治理模式与欧美公司有差异。中国公司应进一步加强ESG治理顶层设计,让ESG成为推动企业高质量发展的重要抓手;加强ESG信息披露及评价体系和能力建设,做好国内外信息披露新规的应对工作;积极参加国家与行业ESG管理标准和规则的制定、完善和提升工作。

企业环保信用评价主体的适格性法理

评价主体适格性是企业环保信用评价制度的基础性法律问题。现有规范规定企业环保信用评价的主体是生态环境部门,生态环境部门作为评价主体是否适格,理论及实践中一直存有疑虑,但既有成果仅限于基本判断,尚缺乏逻辑自洽的法理论证。生态环境部门作为评价主体实施的评价行为在行政法上定性困难,既有的非强制行政手段说、非行政许可审批说、行政确认说等均不能周延解释生态环境部门评价行政行为的定性问题。第三方机构作为环保信用评价主体存在正当的评价权源,即第三方的评价权利具有明确的社会利益需求来源,同时也具备权利来源的认识论基础。企业环保信用评价主体从生态环境部门向第三方机构的转向具有域外法移植的基础,解决了企业环保信用评价活动中权力-权利配置错位问题,妥当厘清了政府权力和市场权利行使的适宜边界。环保信用评价主体适格性的保障规范应从第三方机构的权利配置与义务设定、外部行政监管与内部自我规制协同、法律责任承担规范补强等方面展开。
