Pulse generation models for daily intermittent streamflows / Modèles de génération d’impulsions pour des débits journaliers intermittents

Abstract

Abstract Generating pulses and then converting them into flow are two main steps of daily streamflow generation. Three pulse generation models have been proposed on the basis of Markov chains for the purpose of generating daily intermittent streamflow time series in this study. The first one is based on two two-state Markov chains, whereas the second uses a three-state Markov chain. The third model uses harmonic analysis and fits Fourier series to the three-state Markov chain. Results for a daily intermittent streamflow data series show a good performance of the proposed models.     

A value chain approach to crisis response system: the case of Qingdao

In this paper, we introduce a value chain approach, on the view of the value chain analytic in business management, to be the framework of a crisis response system serving for crisis management strategy in identifying risk sources, responding to unexpected events, and recovering from a shock. This system is not only a computer system but also a system of governmental emergency response mechanism and it is tremendous and complex. The system integrates and coordinates the correlative resources of emergency response units of the city. We consider the efficiency of the system. In addition, the run cost of the system also is taken into account. Based on this framework, the Qingdao’s practical situation is analyzed. As a result, a design proposal of the Qingdao’s crisis response system is put forward.     

地勘单位经济运行中关键环节管理与执行力问题探讨

对地勘单位经济运行中的资金管理、成本管理、制度管理等三个关键环节的作用及运行状况进行分析,指出其运行过程中存在的三个共性问题,即制度不健全,经营机制不完善;成本管理滞后,经济效益不明显;资金管理不规范,经济运行质量不高。地勘单位经济运行执行力就是地勘单位实现经济运行目标的能力。提高地勘单位经济运行执行力的关键是解决经济运行中存在的问题,为此提出了建立健全制度、完善经营机制,强化资金管理、确保生产经营正常进行,加强成本管理、提高经济运行质量等对策和措施。探索地勘单位提升管理水平,增强管理执行力,推动煤田地质经济健康持续发展。

First international payment for marine ecosystem services: The case of the Banc d’Arguin National Park,Mauritania

This article investigates whether the European Union-Mauritania fisheries agreement, which allocates part of the Europe's financial contribution to the conservation of marine ecosystems located within the Banc d’Arguin National Park, can be regarded as a payment for ecosystem service. A framework for qualification as such payment scheme was established based on an extensive literature review. The criteria identified for the qualification as a payment to ecosystem service pertain to: (1) the definition of the ecosystem service(s) involved; (2) the mechanism involved by the payment; and (3) the nature of the transaction. Interviews with local beneficiaries and subsequent data analysis led to the conclusion that this mechanism could be regarded as a payment to ecosystem service and so, through the European Union-Mauritania Fisheries agreement, the European Union were investing to protect local fish resources that could be exploited by its fishing fleet. This agreement, involving the first International Payment to Ecosystem Service of this kind, marks an important step towards better consideration of marine conservation in international public policy and foreign fishing policy in particular. However, this payment is small when compared to revenues generated through the exploitation of developing countries’ fishing grounds by fishing countries. Nevertheless it opens the door for more detailed applications of payment to ecosystem service schemes to other ecosystems contexts, and can provide a useful alternative source of financing of marine biodiversity conservation.     

传统农林复合系统:一种全球重要文化遗产类型(英文)

作为一种土地利用活动,传统农林复合系统已经经历了成百上千年的历史,并且依然发挥着重要的作用在世界上,特别是热带和亚热带地区。在全球变化和粮食安全等危机的时代背景下,传统农林复合系统受到越来越多政府和非政府组织的重视,因为传统农林复合系统具有重要的经济、生态和社会文化效益。这与全球重要农业文化遗产要求的特征也相一致,目前为止,已经有5个国家4个典型的传统农林复合系统被列为全球重要农业文化遗产。这些传统农林复合系统具有丰富的农业生物多样性,多重的生态系统服务功能,重要的社会文化价值,无论在区域还是全球水平上。目前传统农林复合系统面临一些威胁和挑战,如人口迁移、市场冲击、气候变化等,但是只要政府和非政府组织、社区、农民之间采取多种方式紧密合作,在未来的全球土地利用活动中,传统农林复合系统必将得到有效保护和推广。     

Total evaporation estimation for accurate water accounting purposes: an appraisal of various available estimation methods

The estimation of total evaporation is fundamental for water accounting, considering its influence on water availability. Moreover, the current increase in water consumption (e.g. in sub-Saharan Africa and the world over), land cover/use changes, deteriorating water quality and the climate change projections in most regions of the world underscore the need to understand water loss. So far, different approaches have been developed and implemented in estimating the variations of total evaporation, with varying accuracies. The aim of this work was therefore, to provide a review of these different approaches for estimating total evaporation, as well as a detailed discussion of their strengths and weaknesses. Findings from this review have shown that total evaporation estimates derived, using ground-based meteorological and micro-meteorological methods are inadequate for representing its large-scale spatial variations. On the other hand, remote sensing technology, which acquires data at different resolutions (i.e. radiometric, spectral, spatial and temporal), provides timely, up-to-date and relatively accurate spatial estimates of total evaporation over large geographic coverage, for sustainable and effective water accounting, which is key for well-informed and improved management of water resources at both catchment and regional scales. In this regard, more details on the remote sensing-based methods of estimating total evaporation are provided, especially considering the robust technological advancements and its potential in characterizing earth features over time and space. This work has also managed to identify research gaps and challenges in the accurate estimation of total evaporation, using remote sensing, especially with the emergence of more advanced sensors and the characteristics of the landscape.
