重庆市不同类型屋顶绿化的降温增湿效应

屋顶绿化是城市立体绿化的主要方式之一,能有效改善城市生态环境。本文以重庆市主城区办公楼屋顶绿化为研究对象,开展不同类型屋顶绿化的降温、增湿效应研究。研究结果表明：绿化屋顶较未绿化屋顶具有明显的降温、增湿效应,且花园式屋顶绿化降温、增湿效应高于简单式屋顶绿化类型;花园式屋顶绿化降温率（T%）为22.14%,增湿效应（R%）为81.16%,而简单式屋顶绿化降温率（T%）为3.71%,增湿效应（R%）为14.7%。本研究以期为改善城市环境,实现城市的可持续发展提供理论依据。     

Book reviews and notices

This study aims to examine the mediating role of the customer environmental satisfaction in the effect of environmental friendliness of products and the company on customer loyalty in using green products in Malaysia. Structural equation modeling (SEM) analysis is performed to test the proposed hypotheses among 200 full time university students with purchasing experience at least once a week green products like organic vegetables. SEM results showed that customer environmental satisfaction significantly affected customer loyalty. This pair of relationships has the highest standardized beta coefficients, signifying the most important aspect of consideration by respondents among the rest of the proposed hypotheses. Next, customer environmental satisfaction partially mediated the relationship between environmental friendliness of products and customer loyalty in using green products. The results confirmed that customers are satisfied with their decision to purchase green products as they consume the least amount of resources and energy which results in minimum environmental damage and are also easy to recycle, disassemble, decompose, and reuse. Marketers should focus on creating effective marketing strategies and green promotional activities to attract customers for their green products. Marketers should control and enhance the quality of green products, as well as emphasizing their environmental satisfaction and increasing customer loyalty levels. This empirical study advanced marketers’ and policy makers’ understanding of the identification of customer environmental satisfaction as a mediator in the relationship between environmental friendliness of products and customer loyalty has been inspected in Malaysian context.     

国内外绿色建筑评价体系及其理论分析

从评价指标、权重体系、评分方式等方面论述了国内外现有的绿色建筑评价体系,理论分析表明：现有评价体系的主要特点为从全生命周期角度确定评价指标、用AHP确定评价体系的层次结构、特尔菲法确定指标权重、指标合成方法由线性求和向加乘混合发展、评价结果都采用分级制以确定建筑实现绿色的程度。最后指出了当前绿色评价体系中存在的两点不足：评价结果存在较强的主观性;重视技术的应用,忽视实际运行效果。     

绿肥轮作对植烟土壤酶活性与微生物量碳和有机碳的影响

为探讨绿肥作物改良土壤的生态作用,试验以冬闲连作地为对照,在云南曲靖和晋宁烟草种植区,研究了小麦轮作收获后留根茬（20 cm左右）翻压后种植烟草（麦-烟）,紫花苕子收获后留根茬（30 cm左右）翻压后种植烟草（绿-烟）及豆类轮作（豆-烟）收获后根茬及秸秆全部移除地外种植烟草的4种轮作模式,结果表明：绿-烟和豆-烟复种模式下,植烟生长期内根区土壤酶活性（SEA）、土壤微生物量碳（SMBC）及土壤有机碳（SOC）均高于麦-烟复种及冬闲连作地,并且差异达显著或极显著水平;不同复种模式的SMBC、SOC及SMBC/SOC间呈显著相关性,对提高土壤SEA、SMBC与SOC质量分数影响为：绿-烟〉豆-烟〉麦-烟〉冬闲地。研究认为,SEA及SMBC/SOC可作为评价轮作模式影响烟地红壤质量变化的生物学指标。     

Brown marine algae turbinaria conoides as biosorbent for Malachite green removal: Equilibrium and kinetic modeling

In this study, the biosorption of Malachite green (MG) onto Turbinaria conoides, brown marine algae, was studied with respect to initial pH, temperature, initial dye concentration, and sorbent dosage. The optimum initial pH and temperature values for MG removal were found to be 8.0 and 30°C, respectively. Sorbent dosage was found to strongly influence the removal of MG. Equilibrium studies were carried out to test the validity of the Langmuir (q _max = 66.6 mg/g and b = 0.526 mL mol/L) and the Freundlich (n = 1.826 and K = 3.751 mg/g) isotherms. The kinetic studies indicated the validity of the pseudo first-order and second-order equation.

金融科技与企业绿色转型——影响特征、作用机制与空间溢出效应识别

数字经济时代下的金融科技,是金融服务实体经济高质量发展的新业态新模式。本文基于中国上市企业2011—2021年数据集,对金融科技和企业绿色转型之间的影响和机制进行实证检验。实证结果发现,金融科技能够有效赋能企业绿色转型。特别地,金融科技对于高科技企业、非国有企业和重污染企业的绿色转型驱动力更为突出。机制识别检验发现,金融科技能够缓解财务困境、平滑企业风险与增强绿色创新活力,这些都有助于企业绿色转型实践的深度开展。进一步研究发现,金融科技具有强烈的地理扩散溢出效应,并形成较为显著的“本地—外地”金融科技协同效果,对企业绿色转型产生了可叠加的积极影响。本项研究能够为理解金融科技发展,促进实体经济绿色转型提供新的思路借鉴。
