关于高原水电站更新改造的投资体系思考

高原水电站不同于其他的水电站,由于其地理位置特殊,水电站的重要性毋庸置疑,所以,对于高原水电站的更新改造工程至关重要。本文对高原水电站更新改造投资体系进行了思考。     

黄土高原开发生态旅游前景看好

现代旅游业被视为促进经济发展的推动力，应成为黄土高原地区的先导产业，生态旅游应成为优先发展的旅游项目，本文概述了生态旅游的原则，特性和实质及在黄土高原地区开发生态旅游的必要性前提下，将黄土高原分为12个旅游区，指出黄土高原地区发展生态旅游的不足之处并提出应对策略。     

黄土高原生态环境建设与土壤质量演变

土壤质量高低对植被恢复具有重要作用，它不仅影响植物群落的发生、发育和演替的速度，而且也对生态系统过程、生产力和结构等具有重要影响。植物演替过程．也是物种对土壤肥力逐渐适应、改造及不同物种在不同肥力梯度下相互竞争和代替的过程。因此，植被恢复过程也从多个方面影响着土壤质量，植被是土壤质量改善的重要驱动力之一。黄土高原地区实施退耕还林还草后土壤质量将在某种程度上得以恢复．不同类型植被土壤质量恢复还具有明显差异，并且在一定时间范围内，随恢复时间延长，土壤质量不断改善。

Specialization or diversification? The situation and transition of households’ livelihood in agricultural heritage systems

Zhagana Agriculture-Forest-Animal Husbandry Composite System (ZCS) is the first Globally Important Agricultural Heritage Systems site in the Tibetan Plateau. Similar to many traditional agricultural regions, with the development of tourism and leisure agriculture, the peasant households in ZCS have gradually changed their livelihood strategies and livelihood activities in the past 10 years, resulting in the disappearance of some traditional farming methods and agricultural landscapes with a long history. By taking livelihood assets as the entry point and livelihood strategies as the core, this paper analyzed the basic situation of households’ livelihood and the transition mechanism of different livelihood strategies in order to offer suggestions for the dynamic conservation and sustainable development of Agricultural Heritage Systems (AHS). (1) The livelihood strategies of peasant households in ZCS can be divided into two major categories: specialized strategies and diversified strategies. (2) According to the empirical calculation of the livelihood asset accounting framework of AHS, the average livelihood asset value of peasant households in ZCS is 2.040, showing that the situation of peasant households’ livelihood is inadequate. (3) The transition of peasant households’ livelihood strategies from traditional strategy to specialized or diversified livelihood strategies is mainly influenced by natural assets, human assets, cultural assets, social assets and informational assets. In order to meet the growing material and spiritual needs of peasant households and achieve the sustainable development of ZCS simultaneously, it is suggested that the agriculture-forestry-animal husbandry-tourism composite strategies shall be taken as the development direction of peasant households’ livelihood strategies.     

云南九大高原湖泊的演变与生态安全调控

系统梳理了云南九大高原湖泊(滇池、洱海、抚仙湖、程海、泸沽湖、杞麓湖、星云湖、阳宗海、异龙湖)的演变历程,依据湖泊演化阶段、湖泊生态系统发育阶段、流域社会经济特征、湖泊富营养化阶段、水质类别、生态安全水平、主导功能核心导向划分9个湖泊的管理类型,并提出了预防型、控制型、治理型湖泊流域生态安全调控途径。     

黄土高原地区气候与北大西洋、低纬地区的遥相关

西风带是北大西洋气候区和东亚季风区的纽带,ENSO对西太平洋副高、东南季风和西南季风都有重要影响,因此,对黄土高原地区气候与北大西洋、ENSO区的关系做了进一步的分析,建立了神经网络模型,其模拟值与真实值趋势一致,误差较小,为气候预测的估算提供了新的思路。     

How career plateau beliefs and leader interpersonal unfairness harm job performance in dysfunctional organizational settings

Building on social exchange theory and attribution theory, this study unpacks the relationship between employees' perceptions of organizational politics and job performance, considering the mediating effect of career plateau beliefs and the moderating effect of leader interpersonal unfairness. The findings provide empirical support for the theoretical predictions. An important reason for which perceptions of dysfunctional organizational politics reduce job performance is that employees develop beliefs that opportunities for their career development are limited. This mediating role of career plateau beliefs is particularly salient to the extent that employees are exposed to organizational leaders who treat them with disrespect. Organizations can mitigate the risk that highly politicized decision-making processes lead to negative performance outcomes by stimulating fair interpersonal relationships.
